Transdermal patches are a popular route for drug delivery because of the sustained drug levels, low side effects, reduced hepatitic first-pass effect and ease of use, including self– administration. The basic components of any transdermal delivery system include one or more active pharmaceutical ingredient s (APIs) dissolved or dispersed in a reservoir or inert polymer matrix; an outer backing ...

OBJECTIVE Buprenorphine and fentanyl transdermal patches are used widely for the management of persistent malignant and nonmalignant pain. Buprenorphine and fentanyl transdermal patches, both potent opioids, are considered to be equally efficacious in managing persistent pain. Various retrospective studies comparing dosage changes of buprenorphine and fentanyl patches in persistent pain patient...

Vasomotor symptoms (VMS) are among the most bothersome complaints of postmenopausal women. To date, the most widely studied and effective treatment for VMS is hormone replacement therapy, consisting of estrogen (in women without a uterus) or estrogen plus progestin (in women with a uterus). Traditionally, oral estrogens have been used for treatment. However, over the years, additional estrogen ...

Transdermal drug delivery systems have been around for decades, and current technologies (e.g., patches, ointments, and creams) enhance the skin permeation of low molecular weight, lipophilic drugs that are efficacious at low doses. The objective of current transdermal drug delivery research is to discover ways to enhance skin penetration of larger, hydrophilic drugs and macromolecules for dise...

The efficacy of oral aspirin treatment in the secondary prevention of cardio and cerebro vascular disease is well known. However oral administration is often associated with abdominal discomfort. The feasibility of delivering aspirin transdermally from eudragit and polyvinyl acetate (PVA) matrix-type patches to enhance its antithrombotic efficiency of aspirin was investigated. Transdermal films...

Transdermal Drug Delivery System (TDDS) is one of the systems lying under the category of controlled drug delivery, in which the aim is to deliver the drug through skin in a predetermined and controlled rate. Hypertension is one of the common disorder for the mankind. It is not a disease in itself, but is an important risk factor for cardiovascular mortality and morbidity. The present article d...
