Kapslar

Kapslar is a term with multiple meanings across languages and fields. In Swedish, kapslar is the plural of kapsel, meaning capsule. In pharmacology, a capsule is a dosage form consisting of a shell that encloses an active ingredient. Shells are typically made from gelatin or plant-based materials such as hydroxypropyl methylcellulose. Hard capsules contain powders or pellets; soft capsules hold liquids or semi-solid substances. Capsules offer advantages including taste masking, dosing accuracy, stability, and flexibility in releasing the active ingredient over time or at a specific site in the digestive tract.

In botany, a capsule refers to a type of dry fruit that splits open (dehisces) to release seeds when ripe; many plant families produce capsule fruits with diverse shapes and splitting patterns.

In aerospace and space exploration, a capsule (sometimes called a reentry capsule) is a spacecraft module designed to return to a planet or moon. Such capsules require heat shielding, reliable guidance, and a landing system, often parachutes or retrorockets. Capsule designs have enabled human spaceflight, sample-return missions, and atmospheric reentry research.

In medicine, capsule endoscopy uses a swallowable capsule containing a camera to visualize the gastrointestinal tract, a noninvasive diagnostic method.

Regulatory and safety aspects: Pharmaceutical capsules are regulated for content uniformity, dissolution, and packaging, with manufacturing governed by good manufacturing practices and oversight by agencies such as the FDA or EMA.
