Astemizole

Astemizole is an antihistamine used to treat symptoms of allergic conditions such as hay fever, seasonal allergies, and urticaria (hives). It works by blocking histamine receptors, thereby reducing the effects of histamine in the body, which is responsible for allergy symptoms such as itching, sneezing, and runny nose. Astemizole is a second-generation antihistamine that provides relief without causing significant sedation or drowsiness.

Uses of Astemizole

• Relieves symptoms of hay fever and allergic rhinitis
• Reduces sneezing, itching, and runny nose
• Treats urticaria (hives)
• Manages skin rashes and itching caused by allergies

How Astemizole Works

Astemizole works by blocking histamine receptors (H1 receptors) in the body. Histamine is a substance that the immune system releases during an allergic reaction, leading to symptoms like sneezing, itching, and swelling. By inhibiting histamine action, Astemizole helps alleviate these allergic symptoms.
