Formulations are evaluated through a series of tests to ensure they meet predefined criteria. These tests include: 1. Dissolution Testing: Assessing the rate at which the API is released from the formulation. 2. Stability Testing: Monitoring the formulation under various environmental conditions. 3. Bioequivalence Studies: Comparing the new formulation to existing products to ensure similar bioavailability. 4. Sensory Evaluation: Testing the taste, smell, and texture of oral formulations.
