Portalac Indication

As an ophthalmic for the temporary relief of the signs and symptoms of seasonal allergic conjunctivitis. Also used as a nasal spray for allergic rhinitis.

Portalac Pharmacology

Levocabastine is a selective histamine H1-receptor antagonist exerting inhibitory effects on the release of chemical mediators from mast cells and on the chemotaxis of polymorphonuclear leukocytes and eosinophils. Both histamine and antigens induced conjunctivitis can be inhibited by levocabastine. Levocabastine can also reduce symptoms of allergic rhinitis by preventing an increase in vascular permeability of nasal mucosa.

Portalac Absorption

After instillation in the eye, levocabastine is systemically absorbed, albeit at low levels.

Portalac side effects and Toxicity

Adverse effects include visual disturbances, dry mouth, cough, nausea, eyelid edema and lacrimation.
