What is a transdermal patch?
Transdermal patches are now widely used as cosmetic, topical and transdermal delivery systems. These patches represent a key outcome from the growth in skin science, technology and expertise developed through trial and error, clinical observation and evidence-based studies that date back to the first existing human records. This review begins with the earliest topical therapies and traces topical delivery to the present-day transdermal patches, describing along the way the initial trials, devices and drug delivery systems that underpin current transdermal patches and their actives. This is followed by consideration of the evolution in the various patch designs and their limitations as well as requirements for actives to be used for transdermal delivery. The properties of and issues associated with the use of currently marketed products, such as variability, safety and regulatory aspects, are then described. The review concludes by examining future prospects for transdermal patches and drug delivery systems, such as the combination of active delivery systems with patches, minimally invasive microneedle patches and cutaneous solutions, including metered-dose systems.
When did transdermal products become non-believers?
The late 19th century as a phase of ‘non-belief’ in transdermal products
What are the components of transdermal delivery?
Important components of that work, often associated with transdermal delivery, are the defined delivery system in dose, area, vehicle and device; the quantification of the time course of absorption into urine; and the application of pharmacokinetic principles to quantify the resulting drug delivery kinetics. In Wurster's first set of transdermal studies, his student Sherman Kramer glued a diffusion cell containing a defined dose of salicylate esters to the forearm of his human volunteers and then measured their systemic absorption by the excretion of salicylates in the urine. The extent of absorption could be modified by varying the diffusion area of the cell and by changing the level of skin hydration (Wurster and Kramer, 1961). The primitive diffusion cell designed (Figure 1G) and used in their study appears very much to be the forerunner of cells currently used in transdermal research and could even be considered a first prototype of today's commercial transdermal devices in that the in vivodiffusion cell permitted a precise, area-dependent dosing of a topically applied drug (Roberts, 2013). There are now a number of salicylate esters and other non-steroidal anti-inflammatory products on the market for local pain relief. Skin biopsies and microdialysis have been used to show their selective targeting of deeper tissues in preference to the systemic blood supply (Cross et al., 1998; Roberts and Cross, 1999). More recently, we have suggested that the dermal vasculature is a major conduit to deeper tissues for highly bound anti-inflammatory drugs based upon our analysis of the available microdialysis data (Dancik et al., 2012) and for corticosteroids by biopsy (Anissimov and Roberts, 2011).

Is ephedrine a transdermal drug?
In vitroand in vivoskin permeation studies showed that ephedrine might be a likely candidate for administration by way of the transdermal route (Beckett et al., 1972; Michaels et al., 1975). It was thought that the drug could be incorporated in a polymeric transdermal patch for its decongestant effect (Keith and Snipes, 1981d) and for potential anti-asthmatic therapy (Bhalla and Toddywala, 1988). Subsequent in vitrodrug release studies from a polymeric matrix patch and in vivoabsorption studies in nine healthy volunteers looked promising (Jain et al., 1990). Inventions describing matrix patches containing phenylephrine and phenylpropanolamine were also reported (Keith and Snipes, 1981b,c,). A phenylpropanolamine transdermal patch was investigated in a pilot study with three subjects and showed effective plasma levels for appetite suppression (Devane et al., 1991). However, none of these transdermal patches reached the market. Nevertheless, the lay press has also reported the use of ephedrine patches as an aid to weigh loss (Real Pharma, 2014). However, since 2004, ephedra-containing dietary supplements have been banned by the FDA due to serious toxicities (FDA, 2004).
Is Captopril a transdermal patch?
Captopril, an angiotensin-converting enzyme inhibitor, has also been incorporated into transdermal patches and tested in vivoin animal models.

How does a THC patch get its name?

How does THC work in a matrix patch?

A THC patch delivers an accurate dose all the time, every time. You really can’t say that about most of the common ways to get THC into your system.
What happens when you apply a THC patch?
When you apply a THC patch to your skin, you set up a drug concentration gradient. That just means that at one point (in the patch), there’s a lot of the cannabinoid, while at another point (in your skin), there’s not a lot of the cannabinoid.
