Abstract
Subcutaneous delivery of drugs is the application of medication to the skin surface to enter the skin and to achieve adequate concentration systemic circulation to ensure a therapeutic effectiveness. SDDS offers many benefits over traditional system: it offers controlled drug release, prevents first-line symptoms, compliance with clinicians, ease of use and risk elimination and reducing side effects in contrast to conventional treatment. SDDS includes a continuous drugs release system (SDDS). Stratum corneum works as a barrier to the skin penetration and permeation enhancement techniques can overcome this cap. A subcutaneous patch has a few components including the backup membrane, the drug storage tank, the adhesive layer and the lining. This project provides a survey of SDDS and recent developments in SDDS, its benefits over conventional dosage forms, limitations, different parts for subcutaneous patches, subkutaneous patch types, assessment methods, and progress in this field. This is a comprehensive project.
