For suspensions, the dose must be released in a proper recipient, which might allow the due transfer of the content. In addition, because new standards are issued on a continuing basis, this Collection should not be considered an exhaustive source of all bioeuqivalence applicable laws, regulations, and guidelines in the field.

Uniformity of Delivered Dose: Test must be conducted in unities that have been primed in accordance with the instructions of use. Weightings are executed by a scale with proper sensitivity, bioequivslence calibrated. Consideration for equivalence includes formulation general aspect, pH, viscosity, density, drug active concentration assay, and microbiological tests results [ 4 ]. However, it is noted snvisa several of these drugs are formulated as a suspensions.

The determination of uniformity of delivered dose must be executed in accordance with the following description, taking into account the Pharmacopeia methodology available and assay method for the active ingredient. Accessed 5 May Copies available at our site are denoted by this icon: 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 future.


Data and documents generated must be submitted, as well as essay execution SOP. Waiver of In Vivo Bioa Bioequivalence of dermatological topical medicines: Multisource generic pharmaceutical products: Objective The objective of this document is to introduce 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 guidwlines prove safety and efficacy of these drugs for registration as a generic and similar drug.

Follow official methodology and specification of each active ingredient. To warrant reproducibility of collection of samples, the employment of mechanical actuation methods is recommended.

In addition to considering the data itself, any analysis is based on some hypothesis or assumptions guideliens study situation. Actually, bioequivalence studies with pharmacodynamic endpoints are not required for any topical dosage form.

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.

Plumes generated by actuation of this kind of drug products can be characterized in three stages: The statistical objective is extract valid inferences from a set of data. In this note, we would like to comment a recently published review article on the similarities and differences among some international jurisdictions in accepting bioequivalence approaches for generic topical dermatological drug products [ 1 ]. According to Resolutions RE n.

In addition, data of two different distances from the laser and the orifice of flasks must be evaluated. Shall be conducted in 10 flasks, one collection in the beginning and another at the end of the doses. The results obtained amvisa test drug Tshall be compared to the results of the reference drug Rthus, determining existence or lack of Pharmaceutical Equivalence. Analysis follows the methods of Brazilian Pharmacopeia using the amount of flasks and the specification in accordance with stated volume.


Pharmacodynamic Studies for Nasal Sprays and Aerosols. The scientific advances, as well as new ideas will be welcomed, always, to contribute for the discussion of bloequivalence matter, whose main objective is to offer safe, and efficient and quality products to population.

The analytical method for assay shall yield the determination of the quantity of active ingredient in each delivered dose and the data must be reported as percents of labeled dose.

BCS -based Biowaivers; M 9: Mon Arch Chest Dis.

National Center for Biotechnology InformationU. The essay must be executed with the collection of the first delivered dose immediately after priming and the last labeled dose. The closer they are from the extremes -1 or 1 the stronger is the linear association between the bioequivalemce variables: Considering guiedlines 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.
