A drug delivery system (DDS) is defined as a system for delivering a required amount of a drug to the target site at the expected time.
When a drug is taken orally, the amount of the drug that reaches the affected area and exerts therapeutic effects is only 1/100 to 1/10,000 of the dose taken; the remainder may cause adverse effects in other tissue compartments and body systems. DDS is a technology designed to minimize these disadvantages.
Specifically, technology intended to 3points below.
(1) Targeting (2) Release Control (Slow-release) (3) Stealth (avoidance of metabolic and phagocytosis ※ )
※Pharmacological agent is taken up and digested within phagocites.
DDS controls the pharmacokinetics of drugs in the delivery process from the site of administration to the site of action so as to contribute to improvement of quality of life (QOL) of patients by improving the efficacy of drugs, allowing lower doses to be taken with less frequent administration schedules, and reducing the incidence of adverse reactions.
