Kolki-Plus Tablet is a combination medication formulated to provide symptomatic relief from allergic rhinitis, nasal congestion, cough, and associated fever. Each tablet contains Cetirizine 5 mg, an antihistamine that selectively inhibits peripheral H1 receptors, thereby reducing allergic symptoms such as sneezing, itching, and rhinorrhea. Phenylephrine 5 mg acts as a nasal decongestant by stimulating alpha-adrenergic receptors, leading to vasoconstriction and decreased nasal mucosal edema. Ambroxol 30 mg serves as a mucolytic agent, enhancing the clearance of respiratory tract secretions by breaking down mucus, facilitating expectoration and alleviating cough. Paracetamol 325 mg provides analgesic and antipyretic effects, effectively reducing fever and relieving mild to moderate pain. The synergistic action of these components makes Kolki-Plus Tablet suitable for managing upper respiratory tract infections with allergic and inflammatory components. It is indicated for conditions such as common cold, allergic rhinitis with nasal congestion, bronchitis with productive cough, and associated fever. Caution is advised in patients with hypertension, cardiac disorders, or hepatic impairment. Use under medical supervision is recommended to ensure appropriate dosing and to monitor for potential side effects such as drowsiness, dry mouth, or gastrointestinal discomfort.
