Thus, results of the following tests must be submitted: BCS -based Biowaivers; M 9: Essay must be conducted with three 3 flasks for test drug and three for reference drug. National Center for Biotechnology InformationU. Pharmacopoeia Trials to Nasal Sprays and Aerosols 4.
Global Bioequivalence / Bioavailability Regulatory Guidance Documents §¯`·.¸¸.·´¯`·.¸¸.
Bioavailability of fluticasone propionate and mometasone furoate aqueous nasal spray. Published online Jun Study must be conducted with healthy volunteers, of both genders, whose weights are within the normal range. Though the objective of these drugs is local action, consequences of systemic absorption, such as suppression of the hypothalamus-pituitary-adrenal HPA axismust be taken into consideration.
Nonetheless, only the post-approval guidance RDC48, of October 6thbioequivalenve mentioned the need to assess the drug permeability of topical dermatological products, although this guidance has not specified the experimental procedures to be followed [ 6 ].
In revision process of ResolutionANVISA is considering the need to require additional tests as supportive evidences for safety and efficacy of these products. Bioequivalence approaches such as in vitro release tests, in vitro skin permeation tests, dermatopharmacokinetic studies, and in vivo pharmacodynamic studies for corticosteroids, which are the most common therapeutic class of topical dermatological drug products in Brazil [ 7 ], may guidelijes included as requirements in the future.
Good gguidelines practice GCP: The distinction is that the Brazilian agency usually requests either fast or fed studies, based on how food interacts with gioequivalence PK 2. Upon the end of the foor under the terms of the Article One, the National Health Surveillance Agency shall join other involved Bodies and Institutions and those who stated interest in the matter to indicate representatives for further discussions to consolidate a final text.
It is recommended that design and evaluation parameters of the study be previously discussed and submitted to ANVISA as a protocol.
Only the analysts who are able to evidence competency, or who are properly supervised, might conduct the Pharmaceutical Equivalence essays. Description must follow Brazilian Pharmacopeia; 3.

The weight of each flask must be calculated and must fall within two standard deviations. For suspensions, the dose must be released in a proper recipient, which might allow the due transfer of the content. Essay must be conducted using 10 flasks of test guide,ines and 10 of reference drug. Documents superseded by newer versions are striken through.
Camila Fracalossi Rediguieri, Phone: Operational parameters and conditions that were established for equipment, also, must be submitted. Pharmaceutical Equivalence of Nasal Sprays and Aerosols 3. To warrant reproducibility of collection of samples, the employment of mechanical actuation methods is recommended.
Therefore, plasmatic concentrations of drugs that are administered by nasal route result from local and oral absorption. Correlation yielded values are between -1 and 1. Presentation of Biopharmaceutical and Bioanalytical Data in Module 2.
Uniformity of Delivered Dose: A new approach to char For drugs that are administered by nasal route, bioavailability is related to a series of factors: Bioavailability and bioequivalence trials for nasal aerosols and nasal sprays for local action, Draft, According to Resolutions RE n.
Survey of international regulatory bioequivalence recommendations bioequivqlence approval of generic topical dermatological drug products. This Resolution shall be in effect on the date of its publication. Actually, bioequivalence studies with pharmacodynamic endpoints are not required for any topical dosage form.
Test must be executed with the vertical, or close to the vertical positioning of flasks. Brazilian Health Surveillance Agency.

Objective The objective of this document is to guidelinrs a series of recommendations and requirements for the execution of Pharmaceutical Equivalence and Bioequivalence trials with nasal sprays and aerosols, listing the necessary essays, methodology and the data to be submitted to ANVISA to prove safety and efficacy of these drugs for registration as a generic and similar drug.
