SAN DIEGO – A comparison of OTC Claritin tablets and over-the-counter Pataday drops at 15 minutes and 24 hours found that the drops were more effective at relieving itchy eyes in patients with allergic conjunctivitis.

A single-center, randomized, double-masked, parallel study enrolled 58 participants with a self-reported history of ocular allergic symptoms with a positive skin test reaction to a seasonal or perennial allergen.

Participants were randomized to receive a double dose of Pataday Once Daily Relief Extra Strength (olopatadine HCl ophthalmic solution 0.7%) and a placebo tablet or a 24-hour Claritin tablet (loratadine 10 mg, Bayer Consumer Health) and a placebo drop, Weisbarth said. .

“Comparisons were made at 15 minutes of onset of activity and then over the 24-hour duration of activity,” he said.

“The conclusion is that a single dose of Pataday Extra Strength was significantly more effective than a single dose of Claritin in two cases of allergic conjunctivitis at two times,” said Weisbarth.

“Pataday is OTC, so patients have more access to the product,” he added. “It’s one of the ways we’re trying to improve the way practitioners serve their patients.”
