What is the Origin of Transdermal Testosterone Delivery?

The term combines "transdermal," from the Latin trans (across) and Greek derma (skin), with "testosterone delivery," referring to the method of introducing the hormone into the body. The development of this method aimed to overcome the limitations and side effects of oral and injectable formulations.

What is the Mechanism of Transdermal Testosterone Delivery?

The testosterone molecule is formulated to penetrate the stratum corneum, the outermost layer of the skin, through passive diffusion down a concentration gradient. Once in the dermis, it enters the capillaries and subsequently the systemic circulation, avoiding the gastrointestinal tract and liver. This mechanism facilitates a continuous, slow release of the hormone, helping to mimic the natural diurnal rhythm of endogenous testosterone production.

Transdermal Testosterone Delivery

Meaning

Transdermal Testosterone Delivery is a pharmaceutical method for administering testosterone by applying the hormone directly to the skin, where it is absorbed into the systemic circulation. This non-invasive route, utilizing gels, patches, or creams, is designed to bypass the hepatic first-pass metabolism associated with oral administration, leading to more stable and physiological serum testosterone levels. This delivery system is a standard approach for testosterone replacement therapy (TRT) in patients with hypogonadism.
