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.

For solutions, hioequivalence can be gravimetrically determined from the weight of the delivered dose, the concentration, and the density of tested solution.

Correlation yielded values are between -1 and 1.

Journal of Bioequivalence & Bioavailability

Published online Jun The environment of lab must have enough room to allow that working areas be kept clean and organized. Systemic bioavailability of fluticasone propionate Oficial da Uni? According to the Resolution RDC n.

The number of units of test product to be manufactured for the BE study is specified in the IN n.

Global Bioequivalence / Bioavailability Regulatory Guidance Documents §¯`·.¸¸.·´¯`·.¸¸.

Editora Atheneu,; – 16 relation on efficacy and safety. The closer they are from the extremes -1 or 1 the stronger is the linear association between the studied variables: Accessed 5 May Support Center Support Center.

Each volunteer must receive drug by an individual flask; All volunteers and staff must wear clean area clothing, including caps, masks, and gloves; Before each application, the device must be tested by trained staff and execution of about 5 actuations is recommended, outside the building, on the day prior to the testing day; Flasks must be bioequivalejce after 5 actuations and, again, after administration in the volunteers.

Drugs that are administrated by nasal route display a characteristic pharmacokinetic behavior, which is absorption by bioequialence distinct routes: Actually, bioequivalence studies with pharmacodynamic endpoints are not required for any topical dosage form.


Concerning the formulation composition for biowaiver of oral dosage forms, the test drug product should preferably use the same excipients as the reference drug product, but other excipients that are well established for the dosage form, administration route, and drug substance in usual amounts are allowed 4. The scientific advances, as well as new ideas will be welcomed, always, to contribute for the discussion of this matter, whose main objective is to offer safe, and efficient and quality products to population.

Formulations used for Systemic Effects: Analysis of the Charge and Recharging data: To warrant reproducibility of collection of samples, the employment of mechanical actuation methods is recommended. Provides information about alteration, inclusion, suspension, reactivation, cancelation post approval of medicines.

We are aware of broken document links caused by a programming error and we are working with the developers to have it corrected in the shortest possible time. Simple actuation must be executed at beginning dose following the preparation in two distances defined between orifice of flask and the impact surface, of at least 3 cm, within 3 to 7 cm variation. Bioequivalence of dermatological topical medicines: Acceptance of clinical trials gor in third countries, for evaluation in MAAs: The submitted applications for BCS-based fkr should enclose documents that confirm the high solubility of the drug and the similarity of dissolution profiles of the test and reference drug products, which should be rapid or very rapid dissolving 4.

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. Because the legal framework of the Brazilian Health Surveillance Agency ANVISA is available only in Portuguese, it might have been difficult to search information properly or to identify updated guidelines.


Analysis of distribution of size of particle: Gelfusoand Tais Gratieri. Standard Chemical Substances SQRwhich have been standardized by the Brazilian Pharmacopoeia, and other pharmacopoeia codes authorized by the current legislation, must be employed. Successful approaches implemented internationally could lead to a global alignment in regulatory requirements and would improve the efficacy of topically administered generic formulations. Analysis follows the methods of Brazilian Pharmacopeia using the amount of flasks and the specification in accordance with stated volume.

The average volume must be determined, only, for drugs whose volumes are stated on the label. GL on multiplicity issues in clinical trials: Survey of international regulatory bioequivalence recommendations for approval of generic topical dermatological drug products.

Food and Drug Administration: Provides information about pharmaceutical equivalence determination and dissolution profile comparison. For solutions, must be determined the relative mass of each actuation per flask by differences in weight before and after actuation. Before beginning clinical phase, volunteers must receive training regarding administration of drugs. Inform that the Resolution proposal shall be availed, in its totality, during the consultation period at the address http: National Center for Biotechnology InformationU.

Bioavailability and bioequivalence trials for nasal aerosols and nasal sprays for local action, Draft, All information generated, as well as SOP to conduct analysis must be printed and submitted.

Study must be conducted with healthy volunteers, of both genders, whose weights are within the normal range. Study must be conducted, preferably, with one single dosage, and multiple dose studies must be justified in protocol.
