Loratadine is marketed under which brand name?

Loratadine is marketed under the brand name Claritin. This antihistamine is primarily used to relieve allergy symptoms such as sneezing, runny nose, and itching. Claritin works by blocking the action of histamine, a substance in the body that causes allergic symptoms. It is a second-generation antihistamine, meaning it is less likely to cause drowsiness compared to first-generation antihistamines.

The other options are associated with different medications and purposes. Flonase is a nasal spray containing fluticasone used to treat nasal symptoms from allergies. Dulcolax is a brand name for bisacodyl, a stimulant laxative. Metamucil is a fiber supplement used to treat constipation. Each of these medications serves distinct functions unrelated to Loratadine, highlighting why Claritin is the correct association for this specific antihistamine.
