What is the objective of using capsules in medicines?

Hard Gelatin Capsules are used in medicines to make drugs easier to take. Many medicines taste bitter or smell unpleasant. Capsules cover the drug inside a smooth shell, so the taste and smell are hidden. This helps patients swallow them comfortably without discomfort. Capsules also protect sensitive medicines from air, light, and moisture, which can spoil the drug. Some capsules are made to dissolve quickly in the stomach for fast action. Others are designed to release the medicine slowly over time for longer effect. Doctors often prefer capsules because they give accurate doses and are easy to handle. Overall, the main purpose of using capsules is to improve safety, effectiveness, and patient comfort when taking medicines.
