cetrizine description

1. CETRIZINE BY:- ATIF KHAN BSC BT II YEAR

2. MECHANISM OF ACTION Cetirizine competes with histamine for binding at H 1 -receptor sites on the effector cell surface, resulting in suppression of histaminic edema, flare, and pruritus . Cetirizine is a non-sedating antihistamine that works by blocking histamine (H-1) receptors on cells . It is similar to the other second generation  antihistamines

3. DESCRIPTION A potent second-generation histamine H1 antagonist that is effective in the treatment of allergic rhinitis, chronic urticaria , and pollen-induced asthma. Unlike many traditional antihistamines, it does not cause drowsiness or anticholinergic side effects.  Cetirizine and other second-generation antihistamines do not readily enter the brain from the blood, and, therefore, they cause less drowsiness.

4. Used to relieve  allergy symptoms such as   watery   eyes   runny   nose   itching eyes/nose sneezing

5. Common side effects include   headache   dry mouth feeling sick   dizziness   tummy pain diarrhoea .
