Formulation and Optimization of Sustained-Release Gastroretentive Microspheres of Vonoprazan Using Box– Behnken Design
Background: Vonoprazan is a novel potassium-competitive acid blocker (P-CAB) with potent acid-suppressive activity; however, its therapeutic efficacy may be limited by rapid gastric emptying. The present study aimed to formulate and optimize sustained-release gastroretentive microspheres of vonoprazan using the ionotro...
