OLOPATADINE HYDROCHLORIDE vs TELDRIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Olopatadine hydrochloride is a selective histamine H1 receptor antagonist and mast cell stabilizer. It inhibits histamine release from mast cells and prevents histamine-induced effects such as increased vascular permeability and pruritus.
TELDRIN contains loratadine and pseudoephedrine. Loratadine is a long-acting tricyclic antihistamine with selective peripheral H1-receptor antagonism. Pseudoephedrine is a sympathomimetic amine that acts as a decongestant by stimulating alpha-adrenergic receptors in the respiratory tract mucosa, causing vasoconstriction.
One drop of 0.1% or 0.2% ophthalmic solution in each affected eye twice daily (every 6-8 hours) for 0.1%; once daily for 0.2%.
1-2 mg orally twice daily; maximum 4 mg/day.
