Prochem Bioceuticals Pvt. Ltd. is a prominent pharmaceutical company that specializes in the production of various healthcare products. One of their notable offerings is Cetra Dc, a medication that contains Cetirizine Hydrochloride and Phenylephrine Hydrochloride in tablet form. Cetra Dc is a pharmaceutical product that combines the active ingredients Cetirizine Hydrochloride and Phenylephrine Hydrochloride. Cetirizine Hydrochloride is an antihistamine that is commonly used to relieve symptoms of allergies such as sneezing, runny nose, and itchy eyes. It works by blocking the action of histamine, a substance in the body that causes allergic symptoms. On the other hand, Phenylephrine Hydrochloride is a decongestant that helps to reduce nasal congestion by constricting blood vessels in the nasal passages. This results in decreased swelling and mucus production, making it easier to breathe. Cetra Dc tablets are typically prescribed to individuals who are experiencing symptoms of allergic rhinitis, such as nasal congestion, sneezing, and itching.
