Bioequivalence studies: Biowaivers01:13

Bioequivalence studies: Biowaivers

292
Body:In certain scenarios, in vitro dissolution tests can replace in vivo bioequivalence studies. This is particularly true when a drug product, though available in varying strengths, maintains proportional similarity in its active and inactive ingredients. In such cases, the need for in vivo bioequivalence studies for lower strength variants may be waived, provided dissolution tests and in vivo studies on the highest strength yield satisfactory results.Bioequivalence can be indicated through...

Drug Products: Biologics, Biosimilars and Interchangeables

288
Body:Biologics, derived from living sources such as humans, animals, or microorganisms, represent a significant category of pharmaceuticals. These complex molecules, developed through advanced biotechnological methods or purified from natural sources, include essential medical treatments like insulin and growth hormones. The complexity of biologics arises from their large molecular structures and the intricate processes required for their production, making them distinct from conventional...

Bioequivalence Data: Statistical Interpretation

240
Body:The statistical interpretation of bioequivalence data is a significant aspect of pharmaceutical research. Bioequivalence refers to the absence of any significant difference in the rate and extent to which the active ingredient in pharmaceutical products becomes available at the site of drug action when administered at the same molar dose under similar conditions. This helps determine if different drug products have similar absorption rates, ensuring their interchangeability.Statistical...

Bioequivalence: Overview01:16

Bioequivalence: Overview

2.0K
Pharmaceutical equivalents, by definition, are drug products with the same active ingredient in the same quantities, encapsulated in identical dosage forms, and intended for the same administration routes. These pharmaceutical equivalents are deemed bioequivalent if the bioavailability of the active entity in the drug preparations is similar. Moreover, pharmaceutical equivalents demonstrating bioequivalence are also regarded as therapeutically equivalent. This means that when used as directed,...

Equivalence: In Vitro and In Vivo Bioequivalence01:17

Equivalence: In Vitro and In Vivo Bioequivalence

259
Body:Bioequivalence studies are crucial in evaluating whether new drugs can match an approved one regarding pharmacological effects and clinical performance. These studies test if drugs, despite different dosage forms, share identical plasma concentration-time profiles. Three types of equivalence are central to these studies: chemical, pharmaceutical, and therapeutic. Chemical equivalence indicates that two or more drug products contain identical active ingredients in equal amounts.

    Area of Science:

    • Biological Sciences
    • Public Health
    • Regulatory Affairs

    Background:

    • The World Health Organization (WHO) Expert Committee convened to standardize the production and control of vaccines and biological substances.
    • International biological reference materials are crucial for ensuring product quality and safety.

    Purpose of the Study:

    • To outline the adoption of new and revised WHO Recommendations, Guidelines, and guidance documents for biological products.
    • To provide an update on international biological reference materials and standards.

    Main Methods:

    • The committee reviewed and adopted several key WHO documents, including guidelines on regulatory assessment of rDNA-derived biotherapeutics, vaccine stability evaluation, and good manufacturing practices.
    • Discussions focused on the development and adoption of international standards for biological substances.

    Main Results:

    • Adoption of WHO guidance on regulatory assessment of rDNA-derived biotherapeutics.
    • Adoption of WHO Guidelines on vaccine stability evaluation and good manufacturing practices for biological products.
    • Adoption of revised WHO Recommendations for recombinant human papillomavirus virus-like particle vaccines.

    Conclusions:

    • The committee's work advances international harmonization in the production and quality control of vaccines and biologicals.
    • Updated reference materials and guidelines support global regulatory authorities and manufacturers in ensuring product safety and efficacy.
