What is the main therapeutic use of loratadine?

Loratadine is an antihistamine primarily used to relieve allergy symptoms. It works by blocking the action of histamine, a substance in the body that is responsible for allergic symptoms such as sneezing, runny nose, and itchy eyes. This makes loratadine particularly effective for individuals suffering from seasonal allergies, hay fever, or other allergic conditions. Due to its low sedative effects compared to older antihistamines, it is often preferred for those who need to manage their allergies without experiencing drowsiness.

In contrast, the other therapeutic uses listed do not align with loratadine's pharmacological profile or mechanism of action. For example, treating hypertension involves medications that specifically lower blood pressure, reducing inflammation requires anti-inflammatory agents, and lowering cholesterol levels is achieved through statins or similar drugs. Therefore, the main therapeutic use of loratadine is indeed to relieve allergy symptoms.
