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.

Therefore, plasmatic concentrations of drugs that are administered by nasal route result from local and oral absorption. 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. 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.

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.

Acceptance of clinical trials conducted in third countries, for evaluation in MAAs: Author information Article notes Copyright and License information Disclaimer. Good clinical practice GCP: Provides information about pharmaceutical equivalence determination and dissolution profile comparison. In the continuous process of revising and updating regulatory recommendations, it is essential that international regulatory authorities and organizations share their experiences.

However, in the case of parenteral oily solutions, the type of oil used as a vehicle has to be qualitatively the same. Initially, all volunteers who had all samples collected must be included in analysis. The profile comparison should be done by f2 metric.

Parenteral aqueous solutions do not have to be formulated with the same inactive ingredients as their reference formulations. Nonetheless, only the post-approval guidance RDC48, of October 6thhas 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 ]. Current Regulatory Agenda of ANVISA, which contains possible future resolutions to be revised over —, includes a discussion on biowaiver requirements and on possible in vitro and in vivo comparability tests for these products.

Guideline for pharmaceutical equivalence determination and dissolution profile comparison—RDC n. The batches must be submitted in parallel to the essays established in the monograph of the Brazilian Pharmacopoeia or remaining official publications, as per the current Resolutions and the referred Guidance.


Thank you for your patience.

Journal of Bioequivalence & Bioavailability

Shall be conducted in 10 flasks, one collection in the beginning and another at the end of the doses. Test must be conducted in unities that have been primed in accordance with the instructions of use.

Accessed 5 Nov Bioequibalence is recommended that time elapsed between first and last actuation does not exceed 1 minute; After last application, volunteers must receive a ml glass bioequivakence 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.

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. Analysis follows the methods of Brazilian Pharmacopeia using the amount of flasks and the specification in accordance with stated volume.

The statistical objective is extract valid inferences from a set of data.

Regarding the dose strength used in the in vivo studies, a guideline vuidelines in RDC n. 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 ].

Such techniques are named resistant or robust. Analysis of the Charge and Recharging data: Other regulatory guidances that should be followed for the establishment of BE are the following: Analysis of acidity or alkalinity of a solution. All information generated, as well as SOP to conduct analysis must be printed and submitted.

For drugs that are administered by nasal route, bioavailability is related to a series of factors: Analysis of distribution of size of particle: Advice on the design of BE studies: The distinction is that the Brazilian agency usually requests either fast guidelinws fed studies, based on how food interacts with the PK 2. Study must be conducted with healthy volunteers, of both genders, whose weights are within the normal range.

International guidelines for bioequivalence of systemically available orally administered generic drug products: Provides information about alteration, inclusion, suspension, reactivation, cancelation post approval of medicines.

Successful approaches implemented internationally could lead to a global alignment in regulatory requirements and would improve the efficacy of topically administered generic formulations. The continuous training must be monitored and capable of identifying improvement needs. 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.


Inform that the Resolution proposal shall be availed, in its totality, during the consultation period at the address http: Schedule of collection of samples must warrant proper characterization of plasmatic profile of drugs, however it must be considerate, besides half-life of elimination, the capability of analytical method to quantify drug by proposed period.

The closer they are from the extremes bioequivalencr or 1 the stronger is the linear association between the studied variables: Molecular mechanisms of corticosteroid actions. 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.

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 weighted after 5 actuations and, again, after administration in the volunteers.

A detailed description of test and reference drug products as to appearance colorcharacteristic odor, viscosity, presence of particles to characterize each one of them. The number of units of test product to be manufactured for the BE study is specified in the IN n. Headed by Coordination of Inspection in Pharmaceutical Equivalence and Bioequivalence Centers CIBIOa working group composed of technicians of Anvvisa Office of Drugs, representatives of universities, manufacturing companies, CROs and professionals was constituted to gather and evaluate data regarding the major aspects of efficacy, safety and quality of these products.

Study must be conducted, preferably, with one single dosage, and multiple dose studies must be justified in protocol.
