Lecope-AD Tablet is a combination pharmaceutical formulation containing Ambroxol 60 mg, Phenylephrine 5 mg, and Levocetirizine 5 mg, designed to provide comprehensive relief from symptoms associated with upper respiratory tract infections and allergic conditions. Ambroxol, a mucolytic agent, facilitates the breakdown and clearance of mucus by enhancing mucociliary transport, thereby aiding in the alleviation of productive cough and congestion. Phenylephrine, a selective alpha-1 adrenergic receptor agonist, acts as a decongestant by constricting dilated blood vessels in the nasal mucosa, reducing nasal swelling and improving airflow. Levocetirizine, a third-generation non-sedating antihistamine, selectively inhibits peripheral H1 receptors, effectively mitigating allergic manifestations such as rhinorrhea, sneezing, and itching. The synergistic action of these active ingredients makes Lecope-AD Tablet suitable for managing symptoms of allergic rhinitis, sinusitis, and bronchitis with associated nasal congestion and cough. It is recommended to be used under medical supervision, with caution advised in patients with hypertension, cardiovascular disorders, or hypersensitivity to any component. The dosing regimen should be adhered to strictly to minimize potential side effects such as drowsiness, dry mouth, or increased blood pressure. Lecope-AD Tablet offers a balanced approach to symptom control, improving patient comfort and respiratory function.
