Which statement about topical medications is true?

• A. They are used systemically to affect the entire body.
• B. They are applied to skin and affect only the treated area.
• C. They require inhalation to be absorbed.
• D. They are always liquids.

Answer: (B)

The main concept is that topical medications are meant to act locally where they’re applied. When you put them on the skin, their primary purpose is to affect the treated area rather than produce widespread effects throughout the body. This is why creams, ointments, gels, and similar forms are used to treat localized skin conditions. Absorption through the skin can occur, and in some cases this can lead to systemic effects if a lot is absorbed or if the skin is compromised, but the goal of topical therapy is typically local action. The other statements aren’t correct: systemic drugs are used to affect the whole body, inhaled medications require inhalation to reach the body, and topical products aren’t restricted to liquids—they come in creams, ointments, gels, sprays, patches, and more.
