The use of biowaivers is in the spirit of avoiding unnecessary human testing whenever possible and facilitates access to drugs in jurisdictions such as the USA, EU, Canada, Australia, and also emerging countries. Usual excipients with quantity consistent with the biowaivers for bioequivalence studies function e.
BCS Biowaivers: Similarities and Differences Among EMA, FDA, and WHO Requirements
Draft guidance for industry, dissolution testing and specification criteria for immediate-release solid oral dosage forms containing BCS class 1 and class 3 drugs. Dosage forms of drug substances with high solubility only in pH 6.
Add to My Bibliography. For the generic biowaivers for bioequivalence studies to be eligible for biowaiver, the reference product should belong to the same BCS class and should meet dissolution profile comparison criteria. When the properties of the API are evaluated in conjunction with the dissolution of the pharmaceutical dosage form, the BCS takes into account three major factors that govern the rate and extent of drug absorption from immediate-release dosage forms.
The Biopharmaceutics Classification System BCSbased on aqueous solubility and intestinal permeability, has enjoyed wide use since as a mechanism for waiving in vivo bioavailability and bioequivalence studies. For immediate-release dosage forms, the quality control test involves a single-point biowaivers for bioequivalence studies test in only one medium generally a compendial test.

In vivo pharmacokinetic data biowaivers for bioequivalence studies be used as surrogate parameters for in vivo solubility and permeability data. With respect to establishing high solubility, the US-FDA appears to have the most stringent recommendations for which pH biowaivers for bioequivalence studies to test. Dosage forms of drug substances that are highly soluble, highly permeable, and rapidly dissolving are eligible for biowaivers under the following conditions:.
Biowaiver Based on Dosage Form Proportionality When a single-dose fasting BE study is conducted on the designated usually highest strength of the drug product, the requirement for the conduct of additional in vivo BE studies on the lower strengths of the same product can be waived, provided that the lower strength 1 is in the same dosage form; 2 is proportionally similar in its active and inactive ingredients; 3 has the same drug biowaivers for bioequivalence studies mechanism for extended-release products ; 4 meets an appropriate in vitro dissolution profile comparison criterion f 2 50 ; and 5 both biowaivers for bioequivalence studies and higher strengths are within the linear pharmacokinetic range.
There is a clear difference between dissolution as a quality control test and dissolution as an in vitro equivalence BE test. As a result, simultaneous filings to multiple regulatory agencies are common within both the innovator and generic pharmaceutical industries 2.

US Food and Drug Administration. Pharmaceutical alternatives not acceptable for ANDA; For prodrug, site of conversion will determine whether permeability of prodrug biowaivers for bioequivalence studies active drug should be determined. When a single-dose fasting BE study is conducted on the designated usually highest strength of the drug product, the requirement for the conduct of additional in vivo BE studies on the lower strengths of the same product can be waived, provided that the lower strength 1 is in the same dosage form; 2 is proportionally similar in its biowaivers for bioequivalence studies and inactive ingredients; 3 has the same drug release mechanism for extended-release products ; 4 meets an appropriate in vitro dissolution profile comparison criterion f 2 50 ; and 5 both lower and higher strengths are within the linear pharmacokinetic range.

Biowaivers for bioequivalence studies Bioequivalence is a vital concern in drug development even more significant in the case of Narrow Therapeutic Index NTI drugs. Biowaivers of other strengths if 1 strength meets BCS biowaiver criteria. With respect to establishing high permeability, the US-FDA will consider in vivo and in situ animal models and in vitro methods, such as those using cultured monolayers of animal or human epithelial cells—for passively absorbed drugs only—as pivotal methods, whereas the EMA and WHO biowaivers for bioequivalence studies these methods to be supportive only.
Nonetheless, these differences are such that, by applying the most conservative of the three jurisdictional approaches, it should be possible for a sponsor to design the same set of BCS biowaiver studies in preparing a submission for worldwide filing to satisfy US, European, and emerging market regulators.
Guidelines on Registration Requirements to Establish Interchangeability ] http: Guidance for industry, dissolution testing of immediate release solid oral dosage forms. This review will explain the BCS-based biowaiver process and its role in drug development, describe how the BCS biowaiver approach evolved from its inception to its present state, and summarize the current state of the BCS biowaiver implementation in several jurisdictions throughout the world.
Composition must be qualitatively the same and quantitatively very similar. Class 1 Drug Products Allowed in WHO and FDA Approaches Dosage forms of drug substances that are highly soluble, biowaivers for bioequivalence studies permeable, and rapidly dissolving are eligible for biowaivers under the following conditions: On the basis of the solubility and permeability of the dosage form, the drug substance is placed in one of four biowaivers for bioequivalence studies.
On the basis of the solubility and permeability of the dosage form, the drug substance is placed in one of four classes: Guidance for industry, bioequivalence recommendations for specific products. Multisource Generic biowaivers for bioequivalence studies products: Another premise underlying the development of the BCS is the recognition that the two key factors governing drug absorption are aqueous solubility and intestinal permeability 5.
For solid oral dosage forms, the evidence of equivalence is determined on the basis bioequivalencw an in vitro dissolution profile comparison between the multisource and the comparator product.

Ideally, access and affordability to medicines for all patients can be facilitated by global pharmaceutical development biowaivers for bioequivalence studies 1. Firms should show that the quantity of excipients used is consistent with the intended use. As per established published regulations, regulatory agencies are tasked with ensuring the quality, safety, and efficacy of all medications that they approve for marketing within their respective countries.
