What is the primary use of an ointment?

The primary use of an ointment is as a semi-solid preparation that is applied externally to the skin or mucous membranes. Ointments are designed to provide a protective barrier, deliver medication, or moisturize skin. Their semi-solid nature allows them to adhere well to the skin, which can enhance the absorption of the active ingredients into the treated area.

Ointments are commonly used for various purposes, including treating skin conditions, providing relief for irritation, and promoting healing. The formulation is typically oil-based, which helps to retain moisture and create a suitable environment for healing. This contrasts with other forms of medication which may serve different purposes, such as liquid medications meant for oral consumption or injections that deliver medication directly into the bloodstream.
