This can make coated tablets more palatable for patients, and can also help to reduce the risk of nausea and vomiting.

The coating on coated tablets can also be used to improve the stability of the active ingredients. This is important for drugs that are sensitive to moisture or light. The coating can also help to protect the active ingredients from being broken down by stomach acid.

Coated tablets are often used for drugs that are taken on a regular basis, such as blood pressure medications and antidepressants. Coated tablets can also be used for drugs that are taken as needed, such as pain relievers and allergy medications.

Dissolution

The dissolution rate of a tablet is an important factor to consider, as it affects the bioavailability of the drug. Coated tablets dissolve more slowly than uncoated tablets, as the coating delays the release of the active ingredients. This can be advantageous for drugs that need to be released slowly over time, such as extended-release drugs. However, it can also be disadvantageous for drugs that need to be released quickly, such as immediate-release drugs.

Controlled Release: Coated tablets can be used to control the release of the active ingredients. This can be important for drugs that need to be released slowly over time, such as extended-release drugs. The coating can be designed to release the active ingredients at a specific rate, which can help to improve the efficacy and safety of the drug.
Protection from Stomach Acid: The coating on coated tablets can also protect the active ingredients from stomach acid. This can be important for drugs that are sensitive to stomach acid, such as enzymes and proteins. The coating can help to prevent the drug from being broken down in the stomach, which can improve its bioavailability.
Taste Masking: The coating on coated tablets can also be used to mask the taste of the active ingredients. This can be important for drugs that have a bitter or unpleasant taste. The coating can help to make the drug more palatable, which can improve patient compliance.
