BCS -based Biowaivers; M 9: Quality Assurance Management of lab must assure that staff received the proper training to perform these tests and to operate equipments. Therefore, only in vitro studies are required for registration of all generic topical dermatological drug products, including those containing corticosteroids. The continuous training must be monitored and capable of identifying improvement needs.

Waiver of In Vivo Bioa Volunteers whose quantification of drug in biological samples were above limit of quantification in less than 4 collection points in one of the treatments, and to whom the quantification of samples displays sufficiently expressive issues that impair comparison between ghidelines and reference performance must be excluded from the study.

National Health Surveillance Agency. Actually, bioequivalence studies with pharmacodynamic endpoints are not required for any topical dosage form.

Journal of Bioequivalence & Bioavailability

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 abvisa in Brazil [ 7 ], may be included as requirements in the future. Brazilian Health Surveillance Agency. Description must follow Brazilian Pharmacopeia; 3.

aanvisa The current guideline describes how pharmacokinetics tests should be performed for those medicines requiring a demonstration of blood level bioequivalence and, in cases where it is not possible to precisely and accurately quantify the drug in circulation, when pharmacodynamic measurements may be accepted.


Standard Chemical Substances SQRwhich have been standardized by the Brazilian Pharmacopoeia, and other pharmacopoeia codes authorized by the current legislation, must be employed. A new approach to char Pharmaceutical Equivalence of Nasal Sprays and Aerosols The Pharmaceutical Equivalence consists in verifying if huidelines drug T complies, integrally, with the specifications of the Pharmacopoeia and with the remaining performance tests biofquivalence described in the Guidance, and if results obtained are equivalent to the results of reference drug R.

Thus, results of the following tests must be submitted: It bbioequivalence recommended that time elapsed between first and last actuation does not exceed 1 minute; After last application, volunteers must receive a ml glass of water to conduct particles of drug that might have remained in oral cavity to gastrointestinal tract; Drug must be administered in a room, and volunteers must be led to another room where blood samples will be drawn, minimizing the cross-contamination.

For suspensions, test must employ the methodology established in available Pharmacopoeia, or a validated methodology in the absence of a Pharmacopeial methodology to determine the delivered dose.

It is biequivalence that design and evaluation parameters of the study be previously discussed and submitted to ANVISA as a protocol. Analysis must be capable of evidencing the identity of the active ingredient in samples of the test and the reference drug product. The weight of flasks after administration is an exclusion criteria, and the mean of the values.

The batches must be submitted in parallel to the essays established in the monograph of the Brazilian Pharmacopoeia guidelknes remaining official publications, as per the current Resolutions and the referred Guidance. Considering that drugs bioequivapence by nasal route reach low plasmatic concentrations, doses administered can be equal, or higher, than therapeutic doses, as long as safety of volunteers is warranted. Formulations used for Systemic Effects: The matter is complex and originates diverging opinions and this proposal does not represent the depletion of this discussion.


GL on multiplicity issues in clinical trials: Objective The objective of this document is to introduce a series of recommendations and requirements for the execution of Pharmaceutical Equivalence and Bioequivalence bioequiivalence 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 bioequivvalence a generic and similar drug.

Molecular mechanisms of corticosteroid actions. The average volume must be determined, only, for drugs whose volumes are stated on the label. Presentation of Biopharmaceutical and Bioanalytical Data in Module 2. Essay must be conducted with three 3 flasks for test drug and three for reference drug. In addition, because new standards are issued on a continuing basis, this Collection should not be considered an exhaustive source of all current applicable laws, regulations, and guidelines in the field.

Before beginning clinical phase, volunteers must receive training regarding administration of drugs. All information generated, as well as SOP to conduct analysis must be printed and submitted. Advice on the design of BE studies: The environment of lab must have enough room to allow that working areas be kept clean and organized. Trials employing working standards, as long as the certification is evidenced, in absence of SQR, shall be admitted.

The weight of each flask must be calculated and must fall within two standard deviations. Provides information about alteration, inclusion, suspension, reactivation, cancelation post approval of medicines.

Acceptance of clinical trials conducted in third countries, for evaluation in MAAs:
