Coated tablets are solid dosage forms of medication that have a protective layer on their surface. This coating can help mask the taste of the drug, make it easier to swallow, and protect the active ingredients from moisture and light. The coating can also control the release of the medication in the body, allowing for a more effective treatment. The coating materials can vary, including substances like sugar or polymer. Some coated tablets are designed to dissolve in the stomach, while others may be enteric-coated to prevent dissolution until they reach the intestine. This targeted release can enhance the drug's effectiveness and reduce side effects.
