Schematic representation delivery of the drug from the patch into the skin
Therapeutic transdermal drug delivery systems (TTDDS) also known as “patches”. Transdermal patch is an alternative dosage form. It is designed to deliver a therapeutically effective amount of drug across a patient’s skin. TTDDS have many indisputable and obvious advantages over other dosage forms:
- The ability to provide more rapid drug effect
- Easy way to use
- Reducing the frequency of the appointment by delivering the required dose of the drug over a longer period of time.
