Pharmaceutical Equivalence of Nasal Sprays and Aerosols The Pharmaceutical Equivalence consists in verifying if test drug T complies, integrally, with the specifications of the Pharmacopoeia and with the remaining performance tests as described in the Guidance, and if results obtained are equivalent to the results of reference drug R.
The EMA redesigned its website in and For suspensions, test must employ the methodology established in available Pharmacopoeia, or a validated methodology in the absence of a Pharmacopeial methodology to determine the delivered dose.
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 ]. Drugs that are administrated by nasal route display a characteristic pharmacokinetic behavior, which is absorption by two distinct routes: To warrant reproducibility of collection of samples, the employment of mechanical actuation methods is recommended.
Follow official methodology and specification of each active ingredient. In addition, because new standards are issued on a continuing basis, this Collection should not be considered an exhaustive source of all current applicable laws, regulations, and guidelines in the field.

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 abvisa between test and reference performance must be excluded from the study.
Though the objective of these drugs is avisa action, consequences of systemic absorption, such as suppression of the hypothalamus-pituitary-adrenal HPA axismust be taken into consideration.
Shall be conducted in 10 flasks, one collection in the beginning and another at the end of anvisz doses. Gelfusoand Tais Gratieri. Disclaimer Although this Collection contains ghidelines of a legal nature, it has been developed for informational purposes only and does not constitute legal advice or opinions as to the current operative laws, regulations, or guidelines of any jurisdiction. All information generated, as well as SOP to conduct analysis must be printed and submitted.
Whenever applicable, in accordance with official methodology of each active ingredient. The results obtained for test drug Tshall be compared to the results of the reference drug Rthus, determining existence or lack of Pharmaceutical Equivalence. 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.

The number of doses generated by each of the unities tested must be counted and related to the declared by manufacturer. 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.
These drugs, mainly, are used to treat allergic rhinitis. Study must be conducted with healthy volunteers, of both genders, whose weights are within the normal range. Training Workshop on P Uniformity of Delivered Dose: Analysis follows the methods of Brazilian Pharmacopeia using the amount of flasks and the specification in accordance with stated volume.
Further, actuation parameters strength, speed and interval between actuationsmust be established and controlled. Follow official methodology and specification for each active ingredient; 3.
Advice on the design of BE studies: Inflammation of a CRO in order to comply with written instructions rather than following common sense. Standard Chemical Substances SQRwhich have been standardized by the Brazilian Pharmacopoeia, and other pharmacopoeia codes authorized by the current legislation, must be employed.
Consideration for equivalence includes formulation general aspect, pH, viscosity, density, drug active concentration assay, and microbiological tests results [ 4 ].
Guidance on aspects of Samples, standard reagents and reference materials must be properly stored to warrant their integrity and traceability. Headed by Coordination of Inspection in Pharmaceutical Equivalence and Bioequivalence Centers CIBIOa working group composed of technicians of General 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.
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.
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. Analysis of the Charge and Recharging data: Analysis must be capable of evidencing the identity of the active ingredient in samples of the test and the reference drug product. Waiver of In Vivo Bioa Only the analysts who are able to evidence competency, or who are properly supervised, might conduct the Pharmaceutical Equivalence essays.
Analysis of the Uniformity of DeliverdDose: Author information Article notes Copyright and License information Disclaimer. This analysis must be executed in 3 three unities of test and reference drug, using the same impact mechanisms, executing actuation on a proper target.
It is recommended a distance of 2 to 7 cm between the laser and the orifice, and that they hold a detachment of 3 cm, or more, between them. This Resolution shall be in effect on the date of its publication.

Therefore, plasmatic concentrations of drugs that are administered by nasal route result from local and oral absorption. Such techniques are named resistant or robust.
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. Actually, bioequivalence studies with pharmacodynamic endpoints are not required for any topical dosage bioequivalennce.
