O estudo foi do tipo aberto, randomizado, cruzado, com 2 tratamentos, 2 seqüências, 2 períodos, com uma semana de intervalo entre as doses, nos quais os voluntários receberam em cada período a formulação teste e a formulação de referência. Uma única dose de cada formulação foi administrada a 26 voluntários sadios. A seqüência de tratamento foi determinada por uma lista de randomização gerada automaticamente pelo sistema SCPCM (Sistema de Controle de Pesquisas Cínicas de Medicamentos). As amostras de plasma foram coletadas num intervalo de 36 horas. As concentrações de Fenoximetilpenicilina foram analisadas por cromatografia líquida de alta eficiência acoplada a um detector UV-visível. A partir da curva da concentração de Fenoximetilpenicilina no plasma vs tempo foram obtidos os parâmetros farmacocinéticos: ASC0-t,, ASC0-inf, e Cmax. As médias geométricas da Meracilina e Pen-Ve-Oral® foram: 99.89% (90% CI = 94,62%; 105,46%) para ASC0-t 99.76 (90% CI = 94,09%; 105,78%) para ASC0-inf 101.11% (98.61% - 103.37% ) para Cmax,. Diante dos resultados encontrados de Cmax e ASC0-t e estando dentro do intervalo de confiança entre 80% e 125% proposto pela Agência Nacional de Vigilância Sanitária (ANVISA) e pelo Food and Drug Administration (FDA), conclui-se que a Meracilina - comprimidos (500.000 UI) é bioequivalente ao Pen-Ve-Oral®, de acordo com sua taxa de extensão e biodisponibilidade / Abstract: This study aimed to compare the bioequivalence between Phenoxymethylpenicillin tablets (500.000 UI), a test formulation Meracilina by Aché Laboratórios S/A, and the Pen-Ve-Oral® tablet formulation elaborated by Eurofarma Laboratórios Ltda., Brazil, in healthy human volunteers of both sexes. The study was carried out by using an open, randomized-crossover design, consisting of a two-period treatment, in which the volunteers received, in each period, the test formulation or the reference formulation, with a seven-day washout interval. A single dose of each formulation was administered to 26 healthy volunteers. The treatment sequence was determined by a randomization list, automatically produced by the Clinical Trial Medicine Control System. Plasma samples were obtained over a 36-hour period. Phenoxymethylpenicillin concentrations were analyzed by high pressure liquid chromatography and UV-visible detection (HPLC-UV). From the Phenoxymethylpenicillin plasma concentration vs. time curves, the following pharmacokinetic parameters were obtained: ASC0-t, ASC0-inf, and Cmax. The mean of Meracilina/Pen-Ve-Oral® 500.000 UI percent geometric mean was 99.89% for AUC0-t, 100.86% for AUC0-? and 101.11% for Cmax. The 90% confidence intervals were 94.62 - 105.46%, 95.22 - 106.83% and 98.61 - 103.87%, respectively. Considering the results of Cmax. and AUC0-t within the confidence interval between 80% and 125% proposed by the Brazilian National Agency for Sanitary Surveillance (Anvisa) and for the US Food and Drug Administration (FDA), it was concluded that Meracilina tablet (500.000UI) by Eurofarma Laboratórios Ltda. is bioequivalent to Pen-Ve-Oral® tablet for both rate and extent of bioavailability / Mestrado / Farmacologia / Mestre em Farmacologia
