Ambroxol, Cetirizine, Phenylephrine, Guaifenesin

Ambroxol is a mucolytic agent that helps to thin and break down mucus in the lungs, making it easier to cough up and clear the airways. This medication is commonly used in patients with chronic bronchitis, cystic fibrosis, or other respiratory diseases that cause excessive mucus production.
Cetirizine is an antihistamine that helps to relieve allergy symptoms such as sneezing, runny nose, itching, and watery eyes. It works by blocking the effects of histamine, a substance released during an allergic reaction. This medication is useful for patients with seasonal allergies, hay fever, or perennial allergic rhinitis.
Phenylephrine is a decongestant that helps to narrow the blood vessels in the nasal passages, reducing swelling and congestion. This medication is commonly used to relieve nasal congestion due to the common cold, sinusitis, or allergies.
Guaifenesin is an expectorant that helps to thin and loosen mucus in the lungs, making it easier to cough up and clear the airways. This medication is commonly used in patients with acute bronchitis, chest congestion, or other respiratory infections.
