The purpose of the evaluation of generic products, such as tablets and capsules, is to establish that the two or more products containing the same drug provide the same/similar plasma profiles of the drug -independent of their formulation and manufacturing attributes. Thus, evaluation or testing must be product-independent. If requirements and standards are based on product-specific attributes, then these would not be applicable to other products, including generics, as they could have different attributes (formulation/manufacturing). In addition, product-specific testing and standards are similar in concept to labeling an item’s weight (drug, excipient, etc.) with a weighing-scale associated with it – which obviously would be unacceptable.

The concept of product-independent product evaluation would be scientifically valid and facilitate simpler and expeditious product evaluation and approval.

Therefore, the concept of product-dependent assessment of products requires reconsideration. I hope this suggestion will be given favorable consideration.

In my view, the collapse of the regulatory pharmaceutical science as we know it is coming because it is reaching the limits of promoting fake science, regulatory bullying, and disregarding consumer/patient needs and affordability.

To begin with, it is not even possible to know what one means by regulatory pharmaceutical science or regulatory science. It may be considered a hodgepodge collection of documents and checklists, often termed Regulatory Guidance/Guidelines or pharmacopeial monographs, which like-minded groups of people compile them. The main promoted objective of such exercises is to provide “care or help” to customers/patients by establishing the “quality” of pharmaceutical products, such as tablets/capsules, which should be available at reasonable prices. The irony is that no definition or criterion is provided for evaluating the quality of products. The regulatory authorities and pharmaceutical community never defined what a quality pharmaceutical product is. Compliance with guidance reflects quality without an established link between the two (compliance and quality). Thus, everything related becomes illusionary and scientifically invalid, requiring extraordinary efforts, mostly bullying, to promote and maintain the pretense of patients’ safety and product quality

There is, thus, an urgent need for reassessing current regulatory practices so that the manufacturing of pharmaceutical products and their assessments start to make sense and consumers/patients have access to affordable quality pharmaceutical products. Some ideas and suggestions, as links to some articles, are provided in this regard.

Issues:

(1)    Defining roles and practices of pharmaceutical regulatory authorities (Link)

(2)    In-compliance with regulatory standards and requirements do not necessarily mean that a pharmaceutical product (tablet/capsule) or process is of quality! (Link )

(3)    In all seriousness – this is really an “abracadabra” exercise! (Link).

(4)    Quality assessment and prevailing illusions! (Link)

(5)    KABOOM! Pharmaceutical Product Quality Issue (Link)

(6)    Something to think about! (Link).

(7)    Bio-waivers! (Link)

(8)    Inspections and quality of pharmaceutical products and/or manufacturing processes – dilemma! (Link)

(9)    Fashionable Nonsense (Link)

(10)Non-GMP compliant dissolution testers but no warning letters! (Link)

(11)A Quality Product – Please Define! (Link).

(12)Let me be bold and direct! (Link)

(13)Assessing quality of pharmaceutical products! (Link).

(14)Scientific and GMP violation! (Link)

(15) Guidance Documents – Deficiency (Link )

(16)f2 – Similarity Factor (Link)

(17)If one likes that a manufactured drug product should be of quality, then one needs to define (tell) what a quality product is? (Link).

Suggested Solutions:

(1)    Quality of Pharmaceutical Products (Link)

(2)    The missing quality definition or metric (Link)

(3)    Product Quality Metric (do not confuse it with drug/medicine quality) (Link

(4)    Universal Dissolution Test/Tester (Link)

(5)    Universal Dissolution Test/Tester – Second Part (Link)

(6)    Promoting quality standards for drug products: Scientifically speaking, please be systematic and logical! (Link)

(7)    Establishing safety, efficacy and quality of drugs and drug-products (tablet/capsule) – serious confusion! (Link)

There is no doubt that regulatory authorities worldwide are facing numerous challenges in establishing efficient availability of quality pharmaceutical products, in particular tablets and capsules. It appears that a lack of clarity of objective/mandate may be the main cause of the problem and, by extension, the reason there are difficulties in addressing these. The following suggestions maybe considered in addressing the current challenges.

  1. If the objective is to facilitate bringing quality products to patients, which indeed is the objective. In that case, authorities should establish a definition of “quality products,” providing a reference quality product with associated measurable quality parameters. No one can manufacture and/or evaluate a quality product without a definition. A suggested definition in this respect is provided here.
  2. On the other hand, if the objective is monitoring the manufacturing quality, which appears to be the main emphasis of current regulatory practices (cGMP etc.). Then, authorities should not be in this business because this is neither their mandate nor they possess competency/expertise in the area. Moreover, they have never developed or manufactured products or run or maintained cGMP manufacturing facilities for commercial purposes. It would, therefore, be impossible to evaluate or guide the industry adequately to establish or run efficient manufacturing facilities.

It is hoped that these suggestions will be given favorable consideration.
