local drug therapy

Local drug therapy involves applying medications directly to a specific area of the body to treat conditions. This includes local anesthetics used for minor surgeries or to block pain in specific nerves, as well as spinal and epidural anesthesia for childbirth or pelvic surgery. Topical anesthetics are applied to the skin, eyes, or mucous membranes.

Dermatologic disorders are frequently treated with local therapies, such as corticosteroid preparations for eczema and dermatitis, sunblocks for sun protection, and topical antibiotics for acne. Various formulations like lotions, creams, and ointments are used for inflamed skin, burns, and fungal infections like thrush. Ophthalmic drugs, such as eye drops for glaucoma or infections, are also administered locally.1
