Which form of medication involves a gel, ointment, or paste absorbed through the skin?

The form of medication that involves a gel, ointment, or paste absorbed through the skin is classified as skin preparation. This method takes advantage of transdermal absorption, where the active ingredients are delivered directly into the bloodstream through the skin. Skin preparations are designed to provide a localized effect at the site of application or a systemic effect, depending on the formulation and the medication’s properties.

This type of medication is often used for various purposes, including pain relief, hormone replacement therapy, and management of chronic conditions. The use of gels, ointments, or pastes allows for a controlled release of medication into the body, making it a beneficial option for both patients and healthcare providers.

Other options like liquid medications are typically administered orally or via injection, while suppositories are designed for rectal or vaginal administration. Inhalers or sprays are used for delivering medication directly into the respiratory tract. Each method has its own unique application, but skin preparations specifically involve topical absorption through the skin.
