kovakapselikuori

Kovakapselikuori, often translated as hard-shell capsule, is a type of pharmaceutical dosage form. It consists of an outer shell, typically made from gelatin or hydroxypropyl methylcellulose (HPMC), which encloses a medicinal substance. The shell is formed by two interlocking halves, which are filled and then sealed together. This design provides a convenient and stable way to administer drugs, particularly those that are bitter, have an unpleasant odor, or are sensitive to degradation.

The primary function of a kovakapselikuori is to protect the active pharmaceutical ingredient (API) until it reaches its intended site of action, usually the gastrointestinal tract. The capsule shell dissolves in the stomach or intestines, releasing the medication for absorption into the bloodstream. The choice of material for the shell can influence the dissolution rate and thus the drug's release profile. Gelatin, derived from animal collagen, is a common and widely used material. HPMC, a plant-derived alternative, is often chosen for vegetarian or vegan formulations, or when there are concerns about gelatin-related allergies.

Kovakapselikuori can contain various forms of medication, including powders, granules, pellets, or even liquids and semi-solids. The manufacturing process involves filling the pre-formed capsule halves with the drug formulation and then sealing them. This method ensures accurate dosing and improves patient compliance due to the ease of swallowing. The integrity of the kovakapselikuori is crucial for the drug's efficacy and safety, as a compromised shell can lead to premature drug release or degradation.
