ABSTRACT:

In the past, drugs were frequently administered orally, as liquids or in powder forms incurred through the utilization of the oral route of drug administration, new dosage forms containing the drug(s) were introduced. As time progressed, there was a need for delivery systems that could maintain a steady release of drug to the specific site of action. Therefore, drug delivery systems were developed to optimize the therapeutic properties of drug products and render them more safe, effective, and reliable. Implantable drug delivery systems (IDDS) are an example of such systems available for therapeutic use. The study of currently available implantable drug delivery systems is the main focus of this review. The major advantages of these systems contain targeted local delivery of drugs at a constant rate, fewer drugs required to treat the disease state, minimization of probable side effects, and better efficacy of treatment. Due to the development of such sustained release formulations, it is now possible to administer unstable drugs once a week to once a year that in the past required frequent daily dosing. Preliminary studies using these systems have shown superior effectiveness over conventional methods of treatment. However, one limitation of these newly developed drug delivery systems is the fact that their cost-to benefit ratio (cost/benefit) is too high which restricts their use over conventional dosage forms. Some of the most recently discovered implants are in the early developmental stages and more rigorous clinical testing is required prior to their use in standard practice.

Key Words: IDDS, Controlled Release, Injectable preparation.
