Transparency in Drug Trial Data: Thwarted by Lobbyists or Embroiled in Controversy?

Posted on by
Reply

Based on a leaked letter from overseas pharma industry bodies, a leading international daily in late July 2013 reported:

“Big pharma mobilizing patients in battle over drugs trials data.”

Some experts consider it as a poignant, if not a bizarre moment in the history of drugs development, keeping patients’ interest in mind. However, the concerned trade bodies could well term it as a business savvy strategy to maintain sanctity of ‘Data Exclusivity’ in real sense.

That said, it is important for the stakeholders to figure out where exactly does this strategy stand between the larger issue of patients’ drug safety and efficacy concerns and the commercial interest of the innovator companies to grow  their business.

Lack of transparency in drug trials data and consequences:

Outside pharmaceutical marketing, some of the biggest scandals in the drug industry have been alleged hiding of data related to negative findings in drug Clinical Trials (CTs) by the innovator companies.

Many stakeholders have already expressed their uneasiness on this wide spread allegation that research based pharmaceutical companies publish just a fraction of their CT data and keep much of the drug safety related information to themselves. Not too distant withdrawals of blockbuster drugs like Vioxx (Merck) and Avandia (GSK) will vindicate this point.

Examples of global withdrawals of drugs, including blockbuster ones, available from various publications, are as follows.

Questionable efficacy for the treatment of sepsis

A recent example:

A recent report indicates that Japan (Tokyo) based Jikei University School of Medicine plans to withdraw a paper on the hypertension drug Diovan of Novartis from the prestigious British Medical Journal (BMJ) due to “data manipulation,” suggesting the drug could help treating other ailments.

The report also indicates that an investigative panel formed by the university to look into the allegations of ‘rigged data’ for Diovan concluded that the results were cooked.

The decision of the Japanese University to withdraw this paper is expected to hurt the reputation of Novartis Pharma AG and at the same time raise ethical concerns about the company’s behavior concerning its best-selling hypertension drug, the report says.

Drug regulators contemplating remedial measures:

Now being cognizant about this practice, some drug regulators in the developed world have exhibited their keenness to disband such practices. These ‘gatekeepers’ of drug efficacy and safety are now contemplating to get the entire published CT data reanalyzed by the independent experts to have a tight leash on selective claims by the concerned pharma companies.

A review reportedly estimates that only half of all CTs were published in full and that positive results are twice as likely to be published than negative ones.

Recently the European Medicines Agency (EMA) has published a draft report for public consideration on greater openness of CT data. As stated above, this proposal allows independent experts to conduct a detail analysis on the safety and effectiveness of new drugs.

Mobilizing patients to thwart transparency?

Interestingly, as stated in the beginning, it has recently been reported that to thwart the above move of the drug regulator in favor of patients’ interest:

“The pharmaceutical industry has mobilized an army of patient groups to lobby against plans to force companies to publish secret documents on drugs trials.”

The same report highlights that two large overseas trade associations had worked out a grand strategy, which is initially targeted at Europe. This is for the obvious reason that the EMA wants to publish all of the clinical study reports that drug companies have filed, and where negotiations around the CT directive could force drug companies to publish all CT results in a public database.

Embroiled in controversy:

It has also been reported simultaneously, “Some who oppose full disclosure of data fear that publishing the information could reveal trade secrets, put patient privacy at risk, and be distorted by scientists’ own conflicts of interest.”

Pharmaceutical trade associations in the west strongly argue in favor of the need of innovator companies to keep most of CT data proprietary for competitive reasons. They reiterate that companies would never invest so much of time and money for new drug development, if someone could easily copy the innovative work during the patent life of the product.

However, the report also states, “While many of these concerns are valid, critics say they can be addressed, and that openness is far more important for patients’ drug safety reasons.“

Addressing the concerns:

To address the above concerns the EMA has reportedly separated clinical data into three categories:

  • Commercially confidential information.
  • Open-access data that doesn’t contain patients’ personal information.
  • Controlled-access data that will only be granted after the requester has fulfilled a number of requirements, including signing of a data-sharing agreement.

However experts do also reiterate, “Risks regarding data privacy and irresponsible use cannot be totally eliminated, and it will be a challenge to accommodate diverse expectations across the scientific and medical community. However, the opportunity to benefit the health of individuals and the public must outweigh these concerns.”

Some laudable responses:

Amidst mega attempts to thwart the move of EMA towards CT data transparency surreptitiously, there are some refreshingly good examples in this area, quite rare though, as follows:

  • As revealed by media, GlaxoSmithKline (GSK) has recently announced that it would share detailed data from all global clinical trials conducted since 2007, which was later extended to all products since 2000. This means sharing more than 1,000 CTs involving more than 90 drugs. More recently, to further increase transparency in how it reports drug-study results, GSK reportedly has decided to disclose more individual patient data from its CTs. GSK has also announced that qualified researchers can request access to findings on individual patients whose identities are concealed and confidentiality protected.The company would double the number of studies to 400 available by end 2013 to researchers seeking data of approved medicines and of therapies that have been terminated from development.
  • Recently Canada reportedly announced the launch of Canadian Government’s new public database of Health Canada-authorized drug CTs. It is believed that providing access to a central database of clinical trials is an initial step that will help fill an existing information gap as the government works to further increase transparency around CTs.
  • The well-known British Medical Journal (BMJ) in one of its editorials has already announced, “BMJ will require authors to commit to supplying anonymised patient level data on reasonable request from 2013.”

All these are indeed laudable initiatives in terms of ensuring long term drug safety and efficacy for the patients.

Conclusion:

It is quite refreshing to note that a new paradigm is emerging in the arena of CT data transparency, for long-term health interest of patients, despite strong resistance from powerful pharmaceutical trade bodies, as reported in the international media. This paradigm shift is apparently being spearheaded by Europe and Canada among the countries, the global pharma major GSK and the medical Journal BMJ.

A doubt still keeps lingering on whether or not independent expert panels will indeed be given access to relevant CT data for meaningful impartial reviews of new drugs, as the issue, in all probability, would increasingly be made to get embroiled in further controversy.

Moreover, if the innovator companies’ often repeated public stand – “patients’ interest for drug efficacy and safety is supreme” is taken in its face value, the veiled attempt of thwarting transparency of CT Data, with an utterly bizarre strategy, by the lobbyists of the same ‘patient caring’ constituent, can indeed be construed as a poignant moment, now frozen in time, in the history of drug development for mankind.

Be that as it may, to resolve this problem meaningfully and decisively, I reckon, a middle path needs to be carefully charted out between reported thwarting moves by pharma lobbyists and the embroiled controversy on the burning issue.

Thus, the final critical point to ponder:

Would the commerce-driven and cost-intensive pharma innovation also not be in jeopardy, affecting patients’ interest too, if the genuine concerns of the innovator companies over ‘CT Data Protection’ are totally wished away?

In the Wonderland of Pharma Generics: Some Steps In, Some Steps Over the Line

Posted on by

To scale-up access to healthcare, especially for the marginalized population of any country, greater access to affordable generic drugs will always remain fundamental, besides improving healthcare infrastructure and its delivery mechanism.

Thus, there should be a robust mechanism across the world to facilitate quick entry of cheaper generic equivalents immediately after patent expiry of the original molecule. Any attempt to step over the line, blocking entry of generics surreptitiously by vested interests must be brought to justice sooner. Such measures assume increasing importance, as without availability of newer generics, unmet medical needs of the most vulnerable section of the society cannot be met effectively by any country.

Newer generics will play a critical role even in the Indian context. Besides many other diseases, India is already known as the diabetic capital of the world with an estimated population of 70 million diabetics by 2020.

Greater access to treatment for such chronic ailments and many other dreaded diseases with increasing trend of prevalence, like cancer, multiple sclerosis, Alzheimer and autoimmune disorders, besides common tropical diseases, would also depend on the availability of cheaper and newer generic medicines.

Global innovators stepping into generics business in emerging markets:

Sniffing the growth opportunities in the generics business in an environment of patent cliff, even many hard-nosed innovator companies have been entering into this business either through local acquisitions or through various collaborative arrangements. Examples of some of these companies are as follows:

  • Novartis entered in generic business with its Sandoz arm
  • Pfizer with collaborative arrangements in India with Aurobindo Pharmaceuticals (India) in March 2009 and with Strides Arcolab in January 2010
  • Daiichi Sankyo acquired Ranbaxy of India
  • GlaxoSmithKline acquired 16 percent stake of Aspen Pharmacare of South Africa,  Laboratorios Phoenix
in in Argentina and signed a development and commercialization license with Dr. Reddy’s Laboratories (DRL)
  • Sanofi acquired Shantha Biotechnics and Universal Medicare of India, Zentiva in Czech Republic, Laboratorios Kendrick in Mexico, Medley in Brazil and Helvepharm in Switzerland
  • Abbott Laboratories acquired the pharmaceutical formulations business of Piramal Healthcare and collaborated with Zydus Cadila

A pro-generic initiative in the west: 

Ireland’s parliament has recently passed a bill on pro-generic initiatives. Under this new law pharmacists will be permitted to substitute branded medicines, which have been designated by the Irish Medicines Board (IMB) as interchangeable.

Currently in Ireland, if a specific brand of medicine is prescribed for a patient, the pharmacist must supply only that brand.

Some steps over the line blocking entry of generics:

Interestingly, to continue marketing high priced innovative drugs even after patent expiry, attempts are still being made to block entry of cheaper generics through equally innovative means by stepping over the line.

On April 15, 2013 ‘The New York Times’ reported several such cases of the recent past in the United States. The report gives details of the players involved in each of these cases.

Prompted by these unfortunate incidents, the Federal Trade Commission (FTC) of the US investigated into the matter involving the American drug companies and charged many of them with ‘anticompetitive behavior’. These practices are no longer new and are being followed by some companies over a long period of time.

One of the latest and elegant, yet a very simple strategy reportedly works as follows:

  • Generic drug makers need samples of patented drugs to generate required regulatory data to obtain marketing approval for launch after the molecules go off patent.
  •  Some innovator companies (named in the report) refuse to sell their patented drugs to generic manufacturers for development of generic equivalents.
  • Traditionally, the generic drug makers purchase their requirements from the concerned wholesalers.
  •  However, because of safety concerns, drugs are now mostly sold with restrictions on who can buy them.
  • This compels the generic manufacturers to ask the innovator companies for samples of the patented products.
  • Unfortunately, mostly they get a negative answer.
  •  In defense, innovator companies explain that they are ensuring any possible improper use of their innovative drugs and also say that no law binds any company to do business with another.

It is alleged that the companies, which most aggressively pursue such measures are those with drugs nearing end of their patent life.

The report indicates that the federal regulators in USA do consider this strategy of creative interpretation of drug safety laws, is illegal.

The news item also indicates that most of these drugs are for serious illnesses like various types of cancers, multiple sclerosis and other rare diseases costing US$ 79,000 to US$ 229,000 a year to patients.

More instances:

Another recent report  highlights that European Union’s anti-trust regulator will fine two European pharmaceutical Company and seven other drug makers for blocking generic drugs against “pay-for-delay” deals. Ranbaxy’s name also features in this report.

The report also states that brand name companies, especially in the western world, have been defending “pay-for-delay” deals to extend patents and avoid costly litigation.

It reports that in a typical case, a generic rival may challenge the patent of a brand-name competitor, which then pays the rival a sum of money to drop its challenge. Interestingly, defenders of the practice call it a legitimate means to resolve patent litigation.

A recent debate:

Another interesting development has come up with the pain killer drug OxyContin of Purdue Pharma, which went off patent in April 2013.

Just before patent expiry, Purdue Pharma reportedly reformulated and pulled out its previous version of OxyContin, without abuse-deterrent measures, from the market giving reasons related to safety and efficacy of the drug.

In the notice to the Federal Register, US-FDA reportedly said, “Compared to original OxyContin, reformulated OxyContin has an increased ability to resist crushing, breaking, and dissolution using a variety of tools and solvents.” The regulator, consequently, barred the generic companies from making copies of the older versions of OxyContin without tamper-resistant qualities.

This development, will not allow drug manufacturers like Teva and Impax to make and launch generic equivalents of older versions of OxyContin.

This report also says that similar request has been filed with US-FDA by Endo Health Solutions Inc. for safety of its old painkiller drug Opana, which could force the generic version of the drug manufactured by Impax’s going out of the market in favor of high priced medicine.

On this development the Generic Pharmaceutical Industry in America has reportedly commented, “Blocking generic drugs could mean leaving behind the millions of patients who stand to benefit from access to lower-cost versions of OxyContin”. Some experts have also expressed apprehension that such a precedent would likely to encourage many others to work for similar safety related changes to extend patent life of a product.

Having said that, it appears to be a complex regulatory issue where the possibility of drug abuse has to be carefully weighed against the benefits of low cost generic entry for greater access to patients.

‘Disparaging’ generic drugs:

Reuters , quoting the French Competition Authority, recently reported from Paris that a global pharmaceutical major has “created a doubt over the quality and the safety of generics, without any proven basis.”

As a result, the report says, the French Competition Authority has fined the drug maker 40.6 million euros (US$52.7 million) for “disparaging” generic competition.

The news report further indicates that this decision followed a complaint of Teva Sante filed in 2010 against communication practices of the branded molecule discouraging the use of its generic versions by the doctors.

The innovator company may appeal against this decision.

European Commission found similar practices:

It is interesting to note that in 2009, the European Commission also reportedly found similar practices, including ‘pay-for-delay deals’ which not only adversely impacted competition, but also delayed entry of cheaper generic drugs into the EU markets.

That said, entry of generic drugs is still not speedy in all therapy areas. In this context, a study titled, “Drug patent expirations and the speed of generic entry,” concluded that the generic industry mostly target chronic drug markets with high turnover products and entry of a generic drug is also greatly influenced by the existing branded substitutes in the marketplace.

Importance of the Indian generic drugs:

According to BCC Research, the global generic drug market is expected to grow at a CAGR of 15 percent over five years registering a turnover of US$ 169 billion in 2014.

In this market, India is now the world’s biggest provider of low priced high quality generic medicines to the developing world. The experts opine in various context, the world must ensure that this vibrant hub of generic drugs does not get adversely impacted at any cost for any vested interest.

According to Pharmexcil pharma exports from India stood at an impressive US$ 14.6 billion during 2012-13 compared to US$ 13.2 billion in 2011-12. Indian Ministry of Commerce had unfolded a ‘Strategy Plan’ to take it to US$ 25 Bn by 2013-14, which currently appears to be a very ambitious objective.

Taken together, India and China now reportedly manufacture over 80 percent of the Active Pharmaceutical Ingredients (APIs) of all drugs used in the United States.

As reported by BMJ from 2003 to 2008, in various programs supported by donor organizations like the Global Fund, generic drugs from India contributed over 80 percent of the medicines used to treat AIDS, including 91 percent of pediatric antiretroviral products and 89 percent of the adult nucleoside and non-nucleoside reverse transcriptase inhibitor markets.

In addition, India is considered to be an extremely valuable source of high quality affordable generic drugs for the treatment of cancer, cardiovascular conditions, infections and other non-infectious chronic diseases and conditions.

Allegations against Indian generic drugs:

In a situation is like these, some aberrations within the Indian generic space like, what has happened currently with Ranbaxy are, at times, made universal and blown out of proportion, probably on behalf the interested players to paint the domestic pharmaceutical industry, in general, black. There is no doubt, however, all such cases of fraud on patients, wherever these take place must be brought to justice.

The issue arises when such instances are grossly generalized. For example, an American Enterprise Institute report titled, “Cheap Indian generic drugs: Not such good value after all?” quoting US-FDA, highlights that “Pharmaceutical companies in developing countries are increasingly falsifying data about the quality of their medicines.”

It further alleges, Indian producers in particular strive to reduce costs by substituting cheaper ingredients or skimping on good manufacturing practices, and often patients and well-informed pharmacists alike will overlook the flaws.

The article laments, “Indian companies and regulators simply deny there is any difference in product quality between their products and those made in the West.”

Indian perspective to the allegation:

In response to such allegations a very recent FICCI –Heal 2012 publication titled “Universal Healthcare: Dream or Reality?” articulated as follows:

“Selected reporting of malpractices in healthcare has painted a poor picture of the sector. However, the instances of misconduct/corruption are miniscule compared to public perception.”

Some important campaigns in favor of generics:

However, a publication from ‘Global Pharmacy Canada’ says,

“Generic medications are just as safe and effective as their brand-name equivalents. All the drugs supplied by the pharmacies we deal with are government approved. The manufacturers they buy from follow strict World Health Organization (WHO) standards for Good Manufacturing Practices (GMP). One or several of the following agencies have approved these manufacturing facilities:

  • Food and Drug Administration (FDA), USA
  • Medicines Control Agency (MCA), UK
  • Therapeutic Goods Administration (TGA), Australia
  • Medicines Control Council (MCC), South Africa
  • National Institute of Pharmacy (NIP), Hungary
  • Pharmaceutical Inspection Convention (PIC), Germany
  • State Institute for the Control of Drugs, Slovak Republic
  • Food and Drug Administration (FDA), India”

Similarly USFDA comments on generic drugs as follows:

“Generic drugs are important options that allow greater access to health care for all Americans. They are copies of brand-name drugs and are the same as those brand name drugs in dosage form, safety, strength, and route of administration, quality, performance characteristics and intended use.”

“Health care professionals and consumers can be assured that FDA approved generic drug products have met the same rigid standards as the innovator drug. All generic drugs approved by FDA have the same high quality, strength, purity and stability as brand-name drugs. And, the generic manufacturing, packaging, and testing sites must pass the same quality standards as those of brand name drugs.”

The growth drivers:

According to a recent study, following are the key growth drivers of the global generic pharmaceutical industry:

  • Governments’ and payers’ need to contain rapidly increasing healthcare expenditures
  • A growing middle-class in emerging markets
  • Longer life expectancy
  • A large number of patent expiries for innovator drugs, many of them are mega blockbusters

All these have contributed to the growth of global generic industry from less than US$ 50 billion in 2004 to over $80 billion by 2011 improving global patient-access to medicines significantly.

The report also says, if a more general definition of off-patent medicines is used to define generics, estimates have placed the size of the industry at closer to $150 billion. In the United States alone, generic sales have more than tripled since 2000 and now exceed $51 billion in 2011.

Encourage speedy entry of generics:

Even the Federal Trade Commission (FTC) in a report titled “Generic Drug Entry Prior to Patent Expiration: An FTC Study,” stated as follows:

“Expenditures on pharmaceutical products continue to grow and often outpace expenditures for other consumer products. Pharmaceutical expenditures concern not only consumers, but government payers, private health plans, and employers as well. Generic drugs offer opportunities for significant cost savings over brand-name drug products.”

In its report FTC recommended that generic drugs should not experience delays when entering the market. The Commission also highlighted that both pharmaceutical innovation and cheaper generic drugs bring enormous benefits to patients.

Conclusion:

It is widely recognized that generic medicines play a key role to improve access to medicines to a very large section of population of the world.

Currently, important policy measures taken by the countries like, United States, United Kingdom, Canada, Holland, Denmark and Germany for increasing use of generic drug have started helping them to achieve this objective. At the same time, such policies are helping them to garner significant savings in their respective healthcare cost.

Out of pocket expenditure towards healthcare being around 80 percent in India, un-interrupted availability of high quality affordable generic medicines will help the patients significantly. This should, no doubt, need to be ably supported by the Government by rolling-out much awaited ‘The Universal Healthcare’ proposal of the High Level Expert Group (HLEG) appointed by the Planning Commission of India, sooner.

To improve demand of generic drugs, the prescribers too need to be influenced by the regulators, as has happened in many countries of the world.

Finally, the requirement to maintain high quality standards for generic medicines should be non-negotiable and continuously be kept under careful vigil of the drug regulators.

The complex dynamics of the global generic drugs market are indeed intriguing. It is indeed a ‘Wonderland’, as it were.

Be that as it may, in this wonderland of pharma generics, as some continue to step in and some others continue to step over the line, it is also important to understand how this industry caters to the healthcare needs of billions of poor and needy.

Respective Governments across the world should facilitate speedy entry of more number of newer generic drugs in the market. Simultaneously, the drug regulators will require bringing to justice to all those forces, which will attempt blocking or delaying entry of generics, causing great harm to a vast majority of patients across the world.

MCI asks Doctors to Prescribe Medicines in Generic Names

Posted on by
Reply

Last week, on January 21, 2013, in a circular addressed to the Dean/Principals of all the Medical Colleges, Director of all the hospitals and Presidents of all the State Medical Councils, the Medical Council of India (MCI) called upon the doctors practicing medicine to prescribe Drugs with Generic names, as far as possible.

The MCI circular reinforced that all Registered Medical Practitioners under the Indian  Medical Council (Professional Conduct, Etiquette and Ethics) Regulations, 2002 will comply with it without fail. At the same time, wide publicity of this regulation be given and necessary steps be taken to ensure observance of this provision in its letter and spirit.

PSC also recommended it:

Prior to this circular, Parliamentary Standing Committee (PSC) for Health and Family Welfare in its recommendation to the ‘Rajya Sabha’ of the Indian Parliament on August 4, 2010, also recommended prescription of medicines by their generic names.

The basic premises:

All these recommendations are reportedly based on the basic premises that high ‘Sales and Marketing’ costs of branded generic drugs in India can be significantly reduced, if prescription in generic names are encouraged, to make medicines available to patients at cheaper and much affordable prices.

‘Sales and Marketing’ expenses of ‘Branded’ drugs:

According to a recent report in BMJ every dollar that the pharmaceutical companies spend on “basic research,” US$ 19 goes toward promotion and marketing.

Another recent report from Forbes India titled “Will Pharma Companies Have to Stop ‘Gifting’ Doctors?“ states as follows:

“The budget that pharma companies have for freebies is huge. According to one estimate, the top 20 drug makers in India spend about $600 million a year on only freebies for doctors. It is still a paltry sum compared to the US, where drug makers spend $58 billion or more annually on marketing drugs, including freebies for doctors.

While the practice of giving gifts to doctors is rampant internationally, several sources told Forbes India that in India it borders on petty corruption. Doctors often refuse to write prescriptions unless they are offered at least Rs 50,000 in cash every time a new drug needs to be prescribed.” 

The prescribers’ ‘diplomatic’ stand:

It is interesting to note that some doctors reportedly are of the view that:

“For the benefit of patients and to get the best possible results, highest quality drugs with best possible pharmacological properties should be used by all doctors. If the quality of generic drugs is up to high standards, doctors should prescribe generic medicines.”

This comment needs to be taken considering that it has been made in response to the above MCI circular by a doctor. However, I reckon, in the real world such intent, as reflected in various independent retail audit reports, is hardly seen getting translated into reality, at least not just yet.

Ongoing debate on the quality issue with generic medicines:

Many opine that there could be a huge quality issue with generic medicines, which could make such drugs unsafe for the patients.

In response, other school of thought leaders often raise, among many others, the following questions:

  1. Are all generic medicines of dubious quality and branded generics are of good quality?
  2. If quality parameters can be doubted for both in many cases, why then raise this issue only in context of generic medicines?
  3. If the quality issues are not much with the larger companies and are restricted to only smaller companies, why then some branded generic drugs of smaller companies prescribed so much by the doctors?
  4. Currently many large companies market the same drugs both as generics and also as branded generics, why then the branded generic versions sell more than their generic equivalents, though manufactured by the same large companies?
  5. Why are the generic medicines available at ‘Jan Aushadhi’ outlets (though small in number) cost a fraction of their branded generic equivalents?
  6. Why do the doctors also not show much interest in prescribing generic medicines as of date?
  7. Why not those who argue that phonetically similar or wrong reading of generic names at the chemist outlets may cause health safety hazard to the patients, also realize that many already existing phonetically similar brand names in totally different therapy areas may cause similar hazards too?
  8. How does a doctor while prescribing a branded generic or generic medicine decide which ones are of good quality and which others are not?

A recent study:

As reported by the US FDA, ‘A recent study evaluated the results of 38 published clinical trials that compared cardiovascular generic drugs to their brand-name counterparts. There was no evidence that brand-name heart drugs worked any better than generic heart drugs. [Kesselheim et al. Clinical equivalence of generic and brand name drugs used in cardiovascular disease: a systematic review and meta-analysis. JAMA.  2008; 300(21) 2514-2526]‘.

Similar studies are also required in India to resolve much hyped ‘quality issue’ for generic medicines.

Some countries are taking similar steps: 

Just to cite an example, as reported by ‘The Guardian” on August 23, 2011, the Spanish government enacted a law compelling the doctors of Spain to prescribe generic drugs rather than more expensive patented and branded pharmaceuticals, wherever available. This move is expected to help the Spanish government to save €2.4 billion (£2.1billion) a year, as in Spain the drugs are partly reimbursed by the government.

As a result, the doctors in Spain will now have to prescribe only in the generic or chemical names of the respective drugs. Consequently the pharmacies will be obliged to dispense ‘the cheapest available versions of drugs, which will frequently mean not the better-known brand names sold by the big drugs firms’.

Interestingly, the above point, though considered as a positive fall-out in Spain, is reportedly taken negatively in India with the oft repeated argument, ‘India is different’.

Prescriptions for generic medicines were a record high in America in 2010:

As per published reports, last year i.e. in 2010, generic medicines accounted for more than 78 percent of the total prescriptions dispensed by retail chemists and long-term care facilities in the US. This is a record high and is four percentage points more than what it was in 2009 and came up from 63% as recorded in 2006.

This vindicates that prescription in generic names is encouraged in the US too for various reasons.

Concerns over pharmaceutical marketing malpractices in India:  

Ethical concerns on significant expenditure towards alleged sales and marketing malpractices since quite some time has further strengthened the demand for prescriptions only in the generic name of a drug.

Frequent reports by Indian media have already triggered a raging debate in the country on the subject, involving even the Government and also the Parliament. It has been reported that a related case is now pending with the Supreme Court for hearing in not too distant future.

In 2010, “The Parliamentary Standing Committee on Health’ expressed its deep concern that ‘the evil practice’ of inducement of doctors continued because the Medical Council of India (MCI) has no jurisdiction over the pharma industry and it could not enforce the code of ethics on it.”

It was widely reported that the letter of a Member of Parliament, Dr. Jyoti Mirdha to the Prime Minister Dr. Manmohan Singh, attaching a bunch of photocopies of the air tickets claiming, “Doctors and their families were beating the scorching Indian summer with a trip to England and Scotland, courtesy a pharmaceutical company”, compelled the Prime Minister’s Office (PMO) to initiate inquiry and action on the subject.

The letter had claimed that as many as 30 family members of 11 doctors from all over India enjoyed the hospitality of the said pharmaceutical company.

In addition Dr. Mirdha reportedly wrote to the PMO stating, “The malpractice did not come to an end because while medical profession (recipients of incentives) is subjected to a mandatory code, there is no corresponding obligation on the part of the healthcare industry (givers of incentives). Result: Ingenious methods have been found to flout the code.”

The report also indicated that the Department of Pharmaceuticals (DoP) is trying to involve the Department of Revenue under the Ministry of Finance to explore the possibilities in devising methods to link the money trail to offending companies and deny the tax incentives.

Incidences of such alleged malpractices related to financial relationship between the pharmaceutical companies and the medical profession are unfolding reasonably faster now. All these issues are getting increasingly dragged into the public debate where government can no longer play the role of a mere bystander.

Taking the first step closer to that direction, Central Board of Direct Taxes (CBDT), which is a part of Department of Revenue in the Ministry of Finance, has now decided to disallow expenses on all ‘freebies’ to Doctors by the Pharmaceutical Companies in India.

A circular dated August 1, 2012 of the CBDT that the any expenses incurred by the pharmaceutical companies on gifts and other ‘freebies’ given to the doctors will no longer be allowed as business expenses. 

The response in favor of ‘Branded Generics’:

The proponents of ‘Branded Generics’ argue that the brand name is built on various differential value parameters to create a proper position of the brand in the minds of healthcare professionals as well as the patients. Thus, brand names offer a specific identity to generic drugs and is of high importance for both the doctors and the patients. 

The areas of complexity:

Those who favor branded generics also highlight, among others, the following three areas of complexity:

1. In India, over 50% medicines prescribed by the physicians are for Fixed Dose Combinations (FDCs), spanning across almost all therapeutic categories. Thus, it could be difficult for doctors to prescribe such medicines in generic names and might equally be difficult for the chemists to dispense such prescriptions.

They also argue that in case of any mistake of dispensing the wrong drug by the chemist inadvertently, the patients could face serious consequences.

2. Currently doctors use brand names to differentiate one formulation from the others. Different brands of even single ingredient medicines may have inherent differences in their formulations like, in the drug delivery systems (controlled/sustained release), kind of coatings allowing dissolution in different parts of alimentary canal, dispersible or non-dispersible tablets, chewable or non-chewable tablets etc. Since doctors are best aware of their patients’ conditions, they may wish to prescribe a specific type of formulation based on specific conditions of the patients, which may not be possible by prescribing only in generic names.

3. Patients also could face other difficulties due to generic prescribing. As is known, different brands of FDCs may have different proportions of same active ingredients. If chemists do not know or have the exact combination prescribed by the doctor in their shops, they would possibly substitute with a different combination of same drugs, which could well be less effective or even harmful to the patients.

The common perception:

The entire issue arises out of the key factor that the patients do not have any say on the use/purchase of a brand/brands that a doctor will prescribe.

It is generally believed by many that doctors predominantly prescribe mostly those brands, which are promoted to them by the pharmaceutical companies in various questionable ways, as reported above.

Thus, in today’s world and particularly in India, the degree of commercialization of the noble healthcare services, as often reported by the media, has reached a new high, sacrificing the ethics and etiquette both in the medical and also in the pharmaceutical sales and marketing practices at the altar of greed and conspicuous consumption.

Conclusion:

The recent MCI circular to doctors calling upon them to prescribe medicines in the generic names making them more affordable to patients, may be an important step towards a better future.

This assumes even greater importance when medicines constitute over 70 percent of the total treatment cost, especially for domiciliary treatment, and around 80 percent of total healthcare expenses is ‘out of pocket’ in our country.

However, the moot point is, the need of the hour calls for a total change in the mindset of all concerned. The importance of genuine care for the societal needs, while being in pursuit of professional excellence, in tandem, should ideally be demonstrated through voluntary measures by the concerned players in this area, leaving enforcement of stringent regulations as a last resort by the Government.

That said, while generic drugs per se are in no way bad for the patients, a careful analysis of all possible risk factors against expected benefits, especially for FDCs and different drug delivery formulations, will be important in the Indian perspective. Without effectively addressing the above issues, if prescriptions in generic names are made mandatory for all drugs, it could possibly be counter productive jeopardizing patients’ safety and interest.
