Topical or cutaneous administration is primarily used to achieve what kind of effect?

• A. Systemic effects
• B. Local effects on the skin
• C. Effects on the respiratory tract
• D. Effects on the brain

Answer: (B)

Topical or cutaneous administration is chosen to produce effects at the site where the drug is applied. The formulations are designed to act locally on the skin—relieving inflammation, itching, or infection right at that surface or within the skin layers—with minimal entry into the bloodstream. This local action is preferred to avoid systemic effects in distant organs. If systemic effects were desired, other routes like oral or injectable delivery (or a transdermal patch intended to distribute the drug systemically) would be used instead. So the primary aim here is local effects on the skin.
