The topical route involves applying a drug to the:

• A. Skin or mucous membranes
• B. Bloodstream
• C. Muscles
• D. Hair follicles

Answer: (A)

The topical route means applying the drug to the body's surfaces where contact occurs with the skin or mucous membranes. This delivery is intended to act mainly at the site of application, providing a local effect (such as a cream for a skin rash) with minimal systemic distribution. While some absorption into the bloodstream can happen, the primary purpose is local treatment, not delivering medicine through the bloodstream or into muscles. Hair follicles are part of the skin, but the route is defined by application to skin or mucous membranes, not by targeting follicles specifically.
