Formulation of Catechin Hydrate Nanocapsule and Study of its Bioavailability

Drug delivery refers to approaches, formulations, technologies, and systems for transporting a pharmaceutical compound in the body as needed to safely achieve its desired therapeutic effect. It may involve scientific site targeting within the body, and also facilitating systemic pharmacokinetics; in any case, it is typically concerned with both quantity and duration of drug’s persistence in the system. Drug delivery is often executedvia a drug’s chemical formulation alone, but it may also involve in drug-devicecombination products. Drug delivery is a concept where much emphasis should be given to dosage form and route of administration.

The choice of the delivery systems is to allow the safe application of the drug with minimum losses. This suggests that the drug in theformulation must be chemically, physically and microbiologically stable. Side-effects of the drug and drug interactions should be avoided or minimized by the use of suitable drug delivery systems.
