Loratidine (Claritin) is best described as which type of drug?

Explanation:
Loratadine is an antihistamine because it blocks histamine H1 receptors, preventing histamine from triggering typical allergy symptoms such as sneezing, itching, runny nose, and watery eyes. It’s a second‑generation antihistamine, designed to minimize sedation, so it often has fewer CNS side effects than older antihistamines. It is not a decongestant (which relieves nasal congestion by vasoconstriction), not an expectorant (which helps loosen mucus), and not a bronchodilator (which opens airways). So its primary action and use align with being an antihistamine.
