Quick dissolving capsules, also known as fast-dissolving capsules, are a type of oral dosage form that is designed to dissolve quickly in the mouth without the need for water.

They are different from other types of capsules, such as traditional hard capsules and soft gel capsules, in several ways:

Formulation: Quick-dissolving capsules are made with ingredients that are formulated to dissolve rapidly in the mouth, such as polymers and other excipients. They are also made in a way that the capsule shells dissolve quickly as well

Dosage form: Quick-dissolving capsules are typically smaller in size than traditional hard or soft gel capsules, which makes them easier to swallow.

Convenience: Quick-dissolving capsules do not require water to swallow, which makes them more convenient for people who have difficulty swallowing pills or have limited access to water.

Taste: Quick-dissolving capsules are designed to have a pleasant taste and can be formulated to mask unpleasant flavors, which makes them more palatable for some people.

Bioavailability: Quick-dissolving capsules can have a faster onset of action due to the fact that they are absorbed directly into the bloodstream via the oral mucosa, bypassing the first-pass metabolism in the liver, which can increase the bioavailability of the active ingredient.

Applications: Quick-dissolving capsules are commonly used for medications that treat conditions such as nausea, motion sickness, and allergies, as well as for vitamins, minerals, and other dietary supplements.
