Xfactor Syrup is a multi-ingredient pharmaceutical formulation designed to provide symptomatic relief in upper respiratory tract conditions characterized by nasal congestion, cough, and allergic manifestations. Each 5 ml dose contains Phenylephrine 5 mg, a selective alpha-1 adrenergic receptor agonist that acts as a decongestant by vasoconstriction of nasal mucosa blood vessels, thereby reducing swelling and congestion. Guaifenesin 50 mg serves as an expectorant, facilitating the loosening and thinning of mucus in the airways to promote productive cough and ease expectoration. Ambroxol 15 mg is a mucolytic agent that enhances mucus clearance by breaking down mucopolysaccharide fibers, improving respiratory function. Levocetirizine 0.8 mg, a potent non-sedating antihistamine, provides relief from allergic symptoms such as sneezing, runny nose, and itching by selectively inhibiting peripheral H1 receptors. Xfactor Syrup is indicated for the management of common cold, allergic rhinitis, bronchitis, and other respiratory conditions involving mucus hypersecretion, nasal congestion, and allergic responses. It should be used as directed by a healthcare professional, with caution advised in patients with hypertension, cardiac disorders, or hypersensitivity to any component. Adverse effects may include mild drowsiness, gastrointestinal discomfort, or dry mouth. This combination offers comprehensive symptomatic relief, improving patient comfort and respiratory function.
