ABSTRACT The present research had as objective to compare the dissolution profiles between the formulations of Ranitidina multifuente manufactured by a national laboratory with the innovative drug. The process was carried out under the same conditions of temperature and time, evaluating 12 tablets of both multi-source and innovative medication in three dissolution media (hydrochloric acid pH 1.2, buffer acetate pH 4.5 and phosphate buffer pH 6.8 ), Which simulated the physiological conditions to which the drugs are exposed inside the organism. A ranitidine standard was used to prepare the calibration curves for each dissolution medium, with solutions being prepared with increasing stimulation. The values of f2 (factor of similarity) found were 83,2561; 75.8412 and 71.0231 for pH 1.2; 4.5, and 6.8, respectively, an independent model used to compare the profiles, being between the 50- 100 range, a specification established by the Food and Drug Administration (FDA), to indicate similarity between two dissolution profiles. To evaluate the drug release kinetics, five mathematical models were applied (zero order, one order, square root, Higuchi and Weibull equation). It was identified that the best solution kinetics of Ranitidine, 300 mg multifuente and innovative tablets, using the Akaike model, was the order one function for the three pH with respect to the multifuente product, and for the innovator was the cubic root function. The results showed that there is no statistically significant difference between the products, which is why the similarity of the multi-source product was demonstrated in relation to the innovative product, based on in vitro dissolution tests
