Kapselhülle

Kapselhülle refers to the outer casing of a capsule, a common pharmaceutical dosage form. This shell, typically made of gelatin or cellulose, encloses the medicinal substance, which can be in powder, liquid, or granular form. The primary function of the Kapselhülle is to protect the enclosed medication from environmental factors such as moisture and light, thereby extending its shelf life and maintaining its potency. It also serves to mask unpleasant tastes or odors of the active pharmaceutical ingredient, making it more palatable for patients.

The Kapselhülle aids in the controlled release of the medication. Depending on the composition and properties of the shell, it can dissolve at different rates within the gastrointestinal tract, influencing how quickly the drug is absorbed into the bloodstream. This characteristic is crucial for optimizing therapeutic efficacy and minimizing potential side effects. Furthermore, capsules are generally easy to swallow, contributing to improved patient compliance, especially for individuals who have difficulty with solid tablets.

There are two main types of capsules based on their structure: hard-shell capsules and soft-shell capsules. Hard-shell capsules, often made of two interlocking cylindrical pieces, are typically used for dry powders or granules. Soft-shell capsules, which are one-piece, elastic shells, are commonly used for liquids or semi-solid fills. The material used for the Kapselhülle can also be adapted for specific needs, such as vegetarian or vegan alternatives to gelatin.
