Soft Gelatin Capsules

Soft gelatin capsules consist of a filling, containing the dissolved or suspected active substance, and of a one-piece shell. Owing to the hermetic seal, the filling ingredients are protected against any harmful influence of the environment. Physical properties of solutions and suspensions, especially their homogeneity, allow the precision of dosage of active ingredients, rare in dry, orally received medications. In comparison with tablets and hard capsules, soft capsules require much less auxiliary substances, most of which are of herbal origin. The possibility to adjust the shell ingredients enables the adaptation of its parameters to specify requirements of storage conditions and especially to chemical as well as pharmacological properties of a medication.
