Nutraceuticals: Still An Oasis Amidst Well Regulated Pharmaceuticals

Nutraceuticals: Still An Oasis Amidst Well Regulated Pharmaceuticals

On November 24, 2016, the food-safety watchdog of India announced that health supplements or Nutraceuticals cannot be sold as ‘medicines’ anymore. This new regulatory standard has been set for the manufacturers of Nutraceuticals and food supplements, and is aimed at controlling mislabeling of such brands. The fine prints of the notification are yet to be assessed.
On the face of it, this new announcement seems to be a good step, and would largely address a long-standing issue on the such products. Prevailing undesirable practices of labeling some pharma brands as food supplements or Nutraceuticals, with some tweaking in the formulations, mainly to avoid the risk of price control, is also expected to be taken care of by the food-safety authority of India, while granting marketing approval.
Nevertheless, it is often construed that off-label therapeutic claims, while promoting these products to the doctors, help achieving brand positioning objective as medicines, though indirectly. Appropriate authorities in India should probably resolve this issue, expeditiously.
In this article, I shall focus on the rationale behind different concerns over the general quality standards, claimed efficacy and safety profile of Nutraceuticals and food supplements, in general, and how the regulatory authorities are responding to all these, slowly, albeit in piecemeal, but surely.
The ‘gray space’ is the issue:
The close association between nutrition and health has assumed a historical relevance. Growing pieces of evidence, even today, suggests that nutritional intervention with natural substances could play an important role, especially in preventive health care. The World Health Organization (WHO) has also highlighted that mortality rate due to nutrition related factors in the developing countries, like India, is nearly 40 percent.
However, as one of the global consulting firm of repute has aptly pointed out, “At one end of this natural nutrition spectrum, are functional foods and beverages as well as dietary supplements, aimed primarily at maintaining health. On the other, more medical end of the spectrum, are products aimed at people with special nutritional needs. In the middle, is an emerging gray area of products that have a physiological effect to reduce known risk factors, such as high cholesterol, or appear to slow or prevent the progression of common diseases such as diabetes, dementia or age related muscle loss.”
This gray space between Pharmaceutical and Nutraceuticals, therefore, holds a significant business relevance, from various perspectives.
An Oasis amidst highly-regulated pharmaceuticals:
Mostly because of this gray space, several pharma companies and analysts seem to perceive the Nutraceutical segment virtually an oasis, lacking any transparent regulatory guidelines, amidst well-regulated pharma business. This perception is likely to continue, at least, for some more time.
Such pattern can be witnessed both within the local and global pharma companies, with some differences in approach, that I shall deliberate later in this article.
However, regulators in many countries, including India, have started expressing concerns on such unfettered manufacturing, marketing and other claims of Nutraceuticals. Many of them even ask, do all these Nutraceuticals deliver high product quality, claimed effectiveness and safety profile to their consumers, especially when, these are promoted by several pharma companies, though mostly off-label, to generate physicians’ prescriptions for various disease treatments?
Not just domestic pharma companies:
This concern is not restricted to the domestic companies in India.
Global pharma players, who generally believe in scientific evidence based medicines, have been reflecting an iffiness towards Nutraceuticals. For example, whereas both Pfizer and Novartis reportedly hived off their nutrition businesses, later Pfizer invested to acquire Danish vitamins company Ferrosan and the U.S. dietary supplements maker Alacer. Similarly, both Sanofi and GlaxoSmithKline also reportedly invested in mineral supplements businesses that could probably pave the way of the company’s entry into medical foods.
However, it is worth underscoring that generally the consumer arms of global pharma companies focus on OTC, and Nutraceuticals do not become an integral part of the pharma business, as is common in India.
Interestingly, not very long ago, Indian pharma industry witnessed a global pharma major virtually replicating the local marketing model involving Nutraceuticals. It also became an international news. On August 24, 2011, ‘Wall Street Journal (WSJ)’ reported that ‘Aventis Pharma Ltd. (now Sanofi India) agreed to buy the branded nutrition pharmaceuticals business of privately held Universal Medicare Pvt. Ltd for an undisclosed amount, as its French parent Sanofi looks to expand in the fast-growing Indian market.’
Universal Medicare, which posted about US$ 24.1 million revenue in the year ended March 31, 2011, will manufacture these branded Nutraceutical products and Aventis will source them from Universal Medicare on mutually agreed terms. Around 750 of the Universal Medicare’s employees also moved to the French Company along with its around 40 Nutraceutical brands, the report said.
If all these acquired brands, do not fall under the new FSSAI guidelines related to the required composition of food supplements and Nutraceuticals in India, it would be worth watching what follows and how.
Nutraceuticals are also promoted to doctors:
Let me reemphasize, India seems to be slightly different in the way most of the pharma companies promote Nutraceuticals in the country. Here, one can find very few standalone ‘Over the Counter (OTC)’ pharma or Nutraceutical product company. For this reason, Nutraceutical brands owned by the pharma companies, usually become an integral part of their prescription product-portfolio. Mostly, through off-label promotion Nutraceuticals are often marketed for the treatment or prevention of many serious diseases, and promoted to the doctors just as any other generic pharma brand.
Need to generate more scientific data based evidences:
A 2014 study of the well-known global consulting firms A.T. Kearney titled, “Nutraceuticals: The Front Line of the Battle for Consumer Health”, also recommended that ‘a solid regulatory framework is crucial for medical credibility, as it ensures high-quality products that can be relied on to do what they say they do.’............

Escalating Antibiotic Resistance, And Thwarting Ban of Irrational FDCs

Escalating Antibiotic Resistance, And Thwarting Ban of Irrational FDCs

September 2016 ‘Fact Sheet’ of the World Health Organization (W.H.O) raised a red flag on fast increasing incidence of Antimicrobial Resistance (AMR). It poses a serious threat to global public health, more than ever before. Consequently, effective prevention and treatment of an ever-increasing and complex range of infections caused by bacteria, parasites, viruses and fungi are becoming more and more challenging.
In this situation, various medical procedures, such as, organ transplantation, cancer chemotherapy, diabetes management and major surgery like, caesarean sections or hip replacements, invite much avoidable a very high element of risk.
Further, a July 2014 paper titled ‘Antibiotic resistance needs global solutions’, published in ‘The Lancet’ reports increase of incidences of drug-resistant bacteria at an alarming rate. In fact, antibiotic resistance is one of the most serious threats in the history of medicine, and new antibiotics and alternative strategies should be sought as soon as possible to tackle this complex problem.
Another more recent paper titled ‘Fixed-dose combination antibiotics in India: global perspectives’, published in ‘The Lancet’ on August, 2016 finds that nowhere in the world this problem is as stark as in India. It emphasizes that the crude infectious disease mortality rate in India today is 416.75 per 100,000 persons, which is twice the rate prevailing in the United States. Misuse, or rather abuse, of Antibiotics is a major driver of resistance. In 2010, India was the world’s largest consumer of antibiotics for human health, the paper says.
Thus, this critical issue calls for urgent action across all government sectors and the society, in general, as W.H.O cautions.
The Devil is also in irrational antimicrobial FDCs:
The reasons for the fast spread of antimicrobial resistance are many, and each one is well documented. One such factor is the use of irrational antimicrobial FDCs. Some of these have already been banned by the Union Government of India, though continue to be manufactured, promoted, prescribed, sold and consumed by the innocent patients unknowingly.
In this article, I shall focus on the banned FDCs of such kind, highlighting how the consequential serious threat to public health and safety is repeatedly getting lost in the cacophony of protracted court room arguments against these bans.
Irrational FDCs and antimicrobial resistance:
That ‘irrational’ FDCs of antibiotics very often hasten the spread of antimicrobial resistance, is now a well-documented fact.
The ‘National Policy for Containment of Antimicrobial Resistance in India 2011’ clearly recognizes that: “Antimicrobial resistance in pathogens causing important communicable diseases has become a matter of great public health concern globally including our country. Resistance has emerged even to newer, more potent antimicrobial agents like carbapenems.” The Policy also recommends removal of irrational antibiotic FDCs from the hospital drug list.
‘The Lancet’ article of August, 2016, as mentioned above, also reiterates, while citing examples, that “Studies of several antibiotic combinations, such as meropenem and sulbactam, have reported no additional advantage over their individual constituents, and have been reported to cause toxic reactions and promote resistance. Despite repeated investigations into the shortcomings of some FDCs, such drugs are still being manufactured and promoted on the Indian drug market.”
Why does it matter so much?
Corrective regulatory measures to contain the spread of antibiotic resistance are absolutely necessary in India, for the sake of the patients. According to a paper titled ‘Antibiotic Resistance in India: Drivers and Opportunities for Action’, published in the PLOS Medicine on March 2, 2016: “Out of around 118 antibiotic FDCs available in the Indian market, 80 (68 percent) are not registered with the Central Drugs Standard Control Organization (CDSCO). Moreover, 63 (19 percent) of around 330 banned FDCs are antibiotics.”
The global relevance:
Such regulatory bans of antimicrobials FDCs in India are important from a global perspective too, as ‘The Lancet’ article of August 2016 observes.
The article recapitulates that the ‘New Delhi metallo-β-lactamase’ – an enzyme that causes bacteria to be resistant to antibiotics, was first reported in India in 2008 and is now found worldwide. The growth of worldwide trade and travel has allowed resistant microorganisms to spread rapidly to distant countries and continents. In addition, some of these banned FDCs in India are reported to be exported to African and Asian countries too.
That said, each country will also need to play a significant role to curtail the abuse or misuse of antibiotics, locally. I find a glimpse of that in England, besides a few other countries.
research paper of Antibiotic Research UK and EXASOL dated November 12, 2015, concluded that overall antibiotic prescriptions are coming down across England. However, the same paper also articulated that in the deprived areas of the country, such as Clacton-on-Sea, antibiotic prescribing rates are almost twice the national average.
Some big MNCs are no different:
In the Government’s ban list of irrational FDCs even some top brands of pharma MNCs feature, including antibiotic FDC of antibiotics. For example, on Mar 14, 2016, Reutersreported that one of the largest pharma MNCs operating in India – Abbott Laboratories, was selling a FDC of two powerful antibiotics Cefixime and Azithromycin, without approval of the DCGI. This could possibly be a legacy factor, arising out of its acquisition of a good number of branded generic drugs, together with their management, from a domestic pharma company. Abbott, otherwise is well regarded by many as a distinguished global institution, practicing high standards of business ethics and values, across the world.
Be that as it may, this powerful antibiotic cocktail that poses huge health risk to patients has reportedly not received marketing approval in the major global pharma markets, such as, the United States, the United Kingdom, Germany, France or Japan.
The Reuters report also elaborates that the drug ‘had been promoted and administered as a treatment for a broad array of illnesses, including colds, fevers, urinary tract infections, drug-resistant typhoid and sexually transmitted diseases.’ It also found chemists who were selling the drug to prevent post-operative infection and for respiratory problems. After the ban, the company has reportedly stopped manufacturing and sales of this antibiotic FDC.
Irrational FDC ban – a significant corrective measure:
Keeping all this in perspective, the regulatory ban on irrational FDCs of antibiotics on March 10, 2016, along with products falling in several different therapy areas, was a significant regulatory measure, among many others, to contain the menace of AMR in India........
