naphazoline + mepyramine + dexpanthenol

Naphazoline + mepyramine + dexpanthenol is a fixed-dose combination of three small molecule drugs primarily formulated for intranasal use to treat symptoms of nasal congestion and related upper respiratory tract discomfort. - **Naphazoline** is a sympathomimetic alpha-adrenergic agonist which acts as a vasoconstrictor on mucosal blood vessels, rapidly reducing swelling and congestion. - **Mepyramine** (also known as pyrilamine) is a first-generation antihistamine acting as a histamine H1 receptor antagonist, reducing itching and other allergy symptoms. - **Dexpanthenol** is a provitamin of B5 with moisturizing and epithelial barrier-restoring properties; it protects and promotes regeneration of mucosal surfaces. This combination is used for symptomatic relief in conditions such as the common cold and rhinitis. The combination aims to provide synergistic decongestant, antihistaminic, and mucosal protective effects.
