In its first reading, the 18-page draft Pharma Policy, 2017 gives me a sense that the Government has followed the much-desired principle of ‘walk the talk’, especially in some key areas. One such space is what Prime Minister Modi distinctly hinted on April 17, 2017, during the inauguration function of a charitable hospital in Surat. He clearly signaled that prescriptions in generic names be made a must in India, and reiterated without any ambiguity whatsoever that, to facilitate this process, his government may bring in a legal framework under which doctors will have to prescribe generic medicines.
Immediately following its wide coverage by both the national and international media, many eyebrows were raised regarding the feasibility of the intent of the Indian Prime Minister, especially by the pharma industry and its business associates, for the reasons known to many. A somewhat muted echo of the same could be sensed from some business dailies too, a few expressed through editorials, and the rest quoting the views on the likely ‘health disaster’ that may follow, if ‘branded generics’ are not prescribed by the medical profession. Obviously, the main apprehension was centered around the ‘shoddy quality parameters’ of unbranded generic drugs in India. It’s a different matter though, that none can possibly either confirm or pooh-pooh it, backed by irrefutable data with statistical significance.
Be that as it may, making high quality generic drugs accessible to most patients at affordable prices, avoiding any possible nexus between the doctors and pharma companies, which could jeopardize the patients’ economic interest, deserves general appreciation, shrill voices of some vested interests notwithstanding. Nonetheless, if the related proposals in the new pharma policy come to fruition as such, it would be a watershed decision of the government, leaving a long-lasting impact both on the patients, as well as the industry, though in different ways, altogether.
I raised this issue in my article titled, “Is Department of Pharmaceuticals On The same Page As The Prime Minister?”, published in this blog on May 15, 2017. However, in today’s discussion, I shall focus only on how has the draft pharma policy 2017 proposed to address this issue, taking well into consideration the quality concerns expressed on unbranded generics, deftly.
Before I do that, let me give a brief perspective on ‘brand name drugs’, ‘generic drugs’, ‘branded generics’ and ‘unbranded generic drugs’. This would basically serve as a preamble to arrive at the relevance of ‘branded generic’ prescriptions, along with the genesis of safety concern about the use of un-branded generic drugs.
No definition in Indian drug laws:
Although, Drugs and Cosmetics Act of India 1940 defines a drug under section 3 (b), it does not provide any legal definition of ‘brand name drugs’, ‘generic drugs’, ‘branded generic drugs’ or ‘un-branded generics’. Hence, a quick landscaping of the same, as follows, I reckon, will be important to understand the pertinence of the ongoing debate on ‘branded generic’ prescriptions in India, from the patients’ health and safety perspectives:
‘Brand name’ drugs:
Globally, ‘brand name drugs’ are known as those, which are covered by a product patent, and are usually innovative New Chemical Entity (NCE) or a New Molecular Entity (NME). Respective innovator pharma companies hold exclusive legal rights to manufacture and market the ‘brand name drugs’, without any competition till the patents expire.
Generic drugs:
Post patent expiry of, any pharma player, located anywhere in the world, is legally permitted, as defined in the Intellectual Property Rights (IPR) regulations, to manufacture, market and sell the generic equivalents of ‘brand name drugs’. However, it’s a global norm that the concerned generic manufacturer will require proving to the competent drug regulatory authorities where these will be marketed, that the generic versions are stable in all parameters, and bioequivalent to the respective original molecules. According to US-FDA, a ‘generic drug’ will require to be the same as the original ‘brand-name drug’ in dosage, safety, strength, quality, purity, the way it works, the way it is taken and the way it should be used.
‘Branded generic’ drugs:
Branded generics are generic molecules marketed and prescribed by their respective brand names. Around 90 percent of generic formulations are branded generics in India, involving heavy sales and marketing expenditure in various forms, which has become a contentious issue today in India. The reason being, although branded generics cost significantly more than unbranded generics, the former variety of generic drugs are most preferred by the medical profession, as a group, in India. Interestingly, there is no difference whatsoever in the marketing approval process between the ‘branded generics’ and other generic varieties without any brand names.
Unbranded generic drugs:
Unbranded generic drugs are those, which are sold only in the generic names, sans any brand name. I reiterate, once again, that there is no difference in the marketing approval process between the ‘branded generics’ and ‘unbranded generic medicines’.
The core issue:
The whole debate or concern related to both efficacy and safety on the use of unbranded generic drugs in India stems from a single regulatory issue, which is widely construed as scientifically improper, and totally avoidable. If this subject is addressed in a holistic way and implemented satisfactorily in the country, by and large, there should not be any worthwhile concern in prescribing or consuming single ingredient unbranded generic drugs in India, which generally cost much less than their branded generic equivalents.
This core issue is primarily related to establishing bioequivalence (BE) with the original molecules for all generic formulations, regardless of whether these are branded or unbranded generic drugs. Thus, positive results in bioequivalence studies, should be a fundamental requirement for the grant of marketing approval of any generics in India, as is required by the regulators of most countries, across the world.
This has been lucidly articulated also in the publication of the National Institute of Health (NIH), USA, underscoring the critical importance of generic drugs in healthcare is unquestionable. The article says: “it is imperative that the pharmaceutical quality and ‘in vivo’ performance of generic drugs be reliably assessed. Because generic drugs would be interchanged with innovator products in the market place, it must be demonstrated that the safety and efficacy of generics are comparable to the safety and efficacy of the corresponding innovator drugs. Assessment of ‘interchangeability’ between the generic and the innovator product is carried out by a study of ‘in vivo’ equivalence or ‘bioequivalence’ (BE).”
The paper further highlights, “the concept of BE has, therefore, been accepted worldwide by the pharmaceutical industry and national regulatory authorities for over 20 years and is applied to new as well as generic products. As a result, thousands of high-quality generic drugs at reduced costs have become available in every corner of the globe.”
Why is BE not mandatory for marketing approval of all generic drugs in India?
It is intriguing, why is this basic scientific and medical requirement of proving BE is not mandatory for granting marketing approval of all generic drugs at all time, without any exception – covering both branded generics and their unbranded equivalents, in India.
As I have already deliberated on this subject in my article titled “Generic Drug Quality: Cacophony Masks An Important Note, Creates A Pariah ”, published in this blog on May 08, 2017, I shall now proceed further to relate this critical issue with the Draft Pharma Policy 2017.
Brand, branding and branded generics:
Nevertheless, before I focus on the draft pharma policy 2017, let me skim through the definitions of a ‘brand’ and the ‘branding process’, in general, for better understanding of the subject…continue
