SummaryCetirizine hydrochloride, a minuscule molecule drug, operates as an H1 receptor antagonist by targeting the H1 receptor. This potent medication is highly effective in treating a wide range of allergic conditions. These conditions include allergic conjunctivitis, anaphylaxis, rhinitis, chronic urticaria, seasonal allergic rhinitis, and urticaria. Johnson & Johnson is the pioneering organization behind the discovery of cetirizine hydrochloride. Medical approval for this remarkable drug was granted in 1991. Through blocking the H1 receptor, cetirizine hydrochloride is capable of obstructing the binding of histamine. Histamine is the prime cause of various allergic reaction symptoms. Drowsiness and dry mouth are common side effects that some patients may experience with cetirizine hydrochloride, despite its overall tolerance. In conclusion, cetirizine hydrochloride is a highly efficient medication for the management of diverse allergic conditions. |
