SLN and NLC not only have the advantages of high physical stability of polymer nanoparticles and slow drug leakage, but also the advantages of liposomes and emulsions with low toxicity, strong transdermal ability, and large-scale production. PhBiochem(vjay_061) TRANSDERMAL DRUG DELIVERY SYSTEM − AKA as transdermal patch − self-contained, discreet dosage form − applied to an intact skin to deliver the drug to the layers of the skin at a controlled rate to the systemic circulation − delivers drug to the general circulation − facilitate the passage of therapeutic quantities of drug substances through the skin and into … The first Transdermal system, transdar -SCOP was approved by FDA in The TDDS avoids first-pass metabolism, which is a significant hindrance for as Transdermal drug delivery systems, Controlled release systems, Transmucosal delivery systems etc. Transdermal drug delivery system is the desirable drug delivery system to control and sustain the drug release via, skin. Transdermal drug delivery (TDD) has recently emerged as an effective alternative to oral and injection administration because of its less invasiveness, low rejection rate, and excellent ease of administration.

Transdermal Drug delivery System: A review. The fentanyl patient-controlled transdermal system incorporates advantages of patient-controlled analgesia (PCA) with a transdermal delivery system. The rate of drug release in this system is defined by: where Ka/r is the partition coefficient for the interfacial portioning of the drug from the reservoir layer to adhesive layer. Transdermal drug delivery system releases the drug by zero (or pseudo zero order) or by first order or both kinetics and which maintain the drug level for prolonged period for desired action. A short summary of this paper. Transdermal delivery systems are topically administered medicaments in the form of patches that deliver drugs for systemic effects at a predetermined and controlled rate.

They produce smooth and nonfluctuating plasma concentration of the drug C. They minimise interindividual variations in the achieved plasma drug concentration D. They avoid hepatic first-pass metabolism of the drug The transdermal route of drug delivery has attracted researchers due to many biomedical advantages associated with it. Avoid GIT absorption problems for drugs. Transdermal patch: A discrete dosage form. More improved and convenient patient compliance. TDDS are more convenient and less invasive tools for disease and viral infection treatment, prevention, detection, and surveillance.
