Guidance for Organizations performing in vivo Bioequivalence Note: ANVISA is constantly redesigning its website starting in Aug Anvisa-Guidance-for-Pharmaceutical-Equivalence-and-Bioequivalence-of-Nasal -Sprays-and-Aerosols_生物学_自然科学_专业资料。Agência. Since , ANVISA has been publishing several Resolutions to establish criteria and requirements to conduct a bioequivalence Trial to register drugs that have.

In the absence of Pharmacopeial method, the study must be undertaking using a method that has been validated by test drug product manufacturer and must be co-validated by the study executer lab, with the complementation of essays described in General Methods of current Brazilian Pharmacopoeia. Analysis follows the methods of Brazilian Pharmacopeia using the amount of flasks and the specification in accordance with stated volume.

For solutions, must be determined the relative mass of each actuation per flask by differences in weight before and after actuation. Author information Article notes Copyright and License information Disclaimer. Please review our privacy policy. It mentions also that the number of subjects in a BE study should be at least 12, but in the case of unknown within-subject variability, the researcher should opt to use a minimum of 24 subjects.

In absence of an official Pharmacopeia monograph, assay must employ validated method provided by the requesting Company that must be co-validated by study executor lab. Uniformity of Delivered Dose: Volunteers, in order to be included in these studies, must be submitted in a clinical evaluation, and no respiratory disease must be found, which includes allergic rhinitis, nasal septal debytion, and adenoid, as they might alter deposition of drug into nasal mucous.

The weight of flasks after administration is an exclusion criteria, and the mean of the values. Qualification of GC Equipment: Copies available at our site are denoted by this icon: Pharmacodynamic studies must comply with the following criteria: In this context, we would like to clarify some misunderstood definitions.


The essays that are required to evidence Pharmaceutical Equivalence of these drugs are: Analysis of the Charge and Recharging data: Mon Arch Chest Dis. It is important to highlight that only BE studies conducted by certified contract research organizations CROs are accepted to support the registration of a generic drug product. Plumes generated by actuation of this kind of drug products can be characterized in three stages: The number of units of test product to be manufactured for the BE study is specified in the IN n.

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 be included as requirements in the cor.

National Center for Biotechnology InformationU. To conduct the essay, is recommended the compliance with the equipment’s manufacturing instructions regarding to obscuration and transmittance percent.

Ajvisa the form and the density of the plume generated by both test and reference spray, using non-impact mechanisms, with visualization by laser light or impact mechanism system, using a proper target that must allow the visualization of the generated spray. Documents superseded by newer versions are striken through.


Molecular mechanisms of corticosteroid actions. Bioavailability and bioequivalence trials for nasal aerosols and nasal sprays for local action, Draft, Drugs that are administrated by nasal route display a characteristic pharmacokinetic behavior, which is absorption by guidelinees distinct routes: Both fast and fed studies are demanded only for prolonged release dosage forms. Linear association measured between two variables.


The results obtained for test drug Tshall be compared to the results of the reference drug Rthus, determining existence or lack of Pharmaceutical Equivalence.

Essay must be conducted using 10 flasks of test drug and 10 of reference drug. International guidelknes for bioequivalence of systemically available orally administered generic drug products: Essay must be conducted with three 3 flasks for test drug and three for reference drug.

Only the analysts who are able to evidence competency, or who are properly supervised, might conduct the Pharmaceutical Equivalence essays. Before beginning clinical phase, volunteers must receive training regarding administration of drugs.

Journal of Bioequivalence & Bioavailability

Determination of nominal volume in liquid products with multiple doses is executed by content weight. Considering that drugs administered 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: We would like to comment on an interesting review article on the similarities and differences among international guidelines for determining bioequivalence BE of generic drug products 1.

Food and Drug Administration: Accepted in February, 29th, Training Workshop on P Camila Fracalossi Rediguieri, Phone: Study must be conducted with healthy volunteers, of both genders, whose weights are within the normal range. The weight of each flask must be calculated and must fall within two standard deviations.

Shall be conducted in 10 flasks, one collection in the beginning and another at the end of the doses.
