Formulation and Evaluation of Tablets Using the Solvent Evaporation Method to Increase the Solubility of Lansoprazole
Abstract
The inability to determine sufficient and repeatable bioavailability and/or desirable pharmacokinetic features in humans is one of the biggest obstacles to the oral administration of new medicines. The solubility and absorption of a medicine determine its bioavailability, which in turn determines its therapeutic efficacy. Achieving the target drug concentration in the systemic circulation and ensuring drug biological activity in humans are both affected by solubility. A stomach ulcer has the potential to rip through the stomach lining, the initial section of the small intestine, and possibly even the lower esophagus. Distinct ulcers form in different parts of the intestines; one forms in the duodenum and one in the stomach. Duodenal ulcers are most commonly characterized by upper abdominal pain at night that subsides after eating. Eating might exacerbate the discomfort from a stomach ulcer. Preparing and assessing the pills will yield optimal outcomes. The active component content is 99.90%, as is the active ingredient release rate. Compared to other formulations, solid dispersion tablets performed better in in-vitro tests (98.85%). The optimized formulation (lansoprazole solid dispersion tablets) outperformed the labeled formulation (conventional lansoprazole tablet) in terms of drug-releasing capacity within 6 hours, outperforming both formulations.
