Abstract: Introduction: Enalapril, an antihypertensive drug commonly used in populations with arterial hypertension, is also a therapeutic option for obese patients. However, the process of bariatric surgery, a prevalent intervention in obesity, introduces a significant challenge. This surgery involves a restriction in nutrient absorption, which can complicate the dissolution and absorption of orally administered drugs, including antihypertensives like Enalapril. Objective: To compare the dissolution profile of Enalapril 20mg tablet presentations marketed in Colombia, simulating pre- and post-bariatric surgery conditions using an in vitro model. Materials and Methods: A biopharmaceutical dissolution profile study of 4 brands of Enalapril was performed by simulating the gastrointestinal conditions of pre- and post-surgical patients undergoing bariatric surgery according to the specifications established in the United States Pharmacopeia 38 for dissolution profiles modifying the pH to emulate the pre-surgical and post-surgical environment. The behavior of each drug in the different media was compared. Results: The methodology, validated using UV-Vis spectroscopy for both acidic and basic media, demonstrated a high level of accuracy with a percentage recovery of 97.53±0.43; 97.67±0.39 for acidic and basic media, respectively. The study confirmed that Enalapril not only met but exceeded the %Q standards set in USP38, a testament to its quality. Importantly, all brands exhibited identical behavior in both pH and volume. Notably, the innovator drug showed no discernible differences from the other brands. Conclusions: This research, with its robust methodology, unequivocally demonstrated that there was no significant difference between the dissolution profiles for each enalapril brand marketed in Colombia, regardless of the pH of the pre-surgical and simulated post-surgical environment. This finding is of utmost importance for the pharmaceutical industry, as it suggests the interchangeability of these brands.
