Global Bioequivalence / Bioavailability Regulatory Guidance Documents §¯`·.¸¸.·´¯`·.¸¸.
The document is an unofficial translation I received at my workshop in Istanbul in March ; I have no idea whether anything has changed in the meantime. Shall be conducted in 10 flasks, one collection in the beginning and another at the guidelimes of the doses. Successful approaches implemented internationally could lead to a global alignment in regulatory requirements and would improve the efficacy of topically administered generic formulations.
Another exclusion criteria used for nasal sprays and aerosols is the occurrence of a sneeze two hours after administration of the drug.
Journal of Bioequivalence & Bioavailability
Volunteers must be previously trained to use the apparatus that will receive the formulation to inhale properly; Before nasal administration 1 minutevolunteers must blow their noses; During nasal application, one of the nostrils must be obstructed while administration is executed anvksa the other nostril. Analysis follows the methods of Brazilian Pharmacopeia using the amount of flasks and the specification in accordance with stated volume.
Mon Arch Chest Dis. 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.
Multisource generic pharmaceutical products: Initially, all volunteers who had all samples collected must be included in analysis. The statistical objective is extract valid inferences from a set of data. Bioavailability and bioequivalence trials for nasal aerosols and nasal sprays for local action, Draft, Good clinical practice GCP: Documents superseded by newer versions are striken through.
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 trials 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 as a generic and similar drug.
Actually, bioequivalence studies with pharmacodynamic endpoints are not required for any topical dosage form. 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.
Whenever applicable, in accordance with official methodology of each active ingredient. To warrant reproducibility of collection of samples, the employment of mechanical actuation methods is recommended. As a result of the low bioavailability of some drugs by nasal administration, it might not be possible to determine elimination half-life t?
National Center for Biotechnology InformationU. Guidance on aspects of Copies available at our site are denoted by this icon: Waiver of In Vivo Bioa For drugs that are administered by nasal route, bioavailability is related to a series of factors: 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 test and reference performance must be excluded from the study.
Published online Jun According to the Resolution RDC n. 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.
Only the analysts who are able to evidence competency, or who are properly supervised, might conduct the Pharmaceutical Equivalence essays. Accessed 5 May 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.
Characterizes 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.
Study must be conducted with healthy volunteers, of both genders, whose weights are within the normal range. Determination of nominal volume in liquid products with multiple doses is executed by content weight.
National Health Surveillance Agency. A detailed description of test and reference drug products as to appearance colorcharacteristic odor, viscosity, presence of particles to characterize each one of them.
Data and documents generated must be submitted, as well as essay execution SOP.
Analysis of the Charge and Recharging 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 ]. Proceed the bioequivlaence using part of the content of ten 10 different flasks, disposing the first actuations necessary for priming, whenever applicable.
For suspensions, the dose must be released in a proper recipient, which might allow the due transfer of the content. Thus, results of the following tests must be submitted: Survey of international regulatory bioequivalence recommendations for approval of generic topical biofquivalence drug products.
