SAN DIEGO — A comparison of over-the-counter Pataday drops with OTC Claritin tablets at 15 minutes and 24 hours showed that the drops were more effective at relieving ocular itching in patients with allergic conjunctivitis.
Rick Weisbarth, OD, FAAO, vice president of professional affairs at Alcon U.S. Vision Care, discussed these study results during an Alcon-sponsored event at Academy 2022.

The single-center, randomized, double-masked, parallel study involved 58 participants with self-reported history of ocular allergic symptoms who had a positive skin test reaction to a seasonal or perennial allergen.
Participants were randomized to receive either a bilateral drop of Pataday Once Daily Relief Extra Strength (olopatadine HCl ophthalmic solution 0.7%) and placebo tablet or a Claritin tablet 24-hour (loratadine 10 mg, Bayer Consumer Health) and a placebo drop, Weisbarth said.
“Comparisons were made at 15 minutes at onset of action and then at 24 hours duration of action,” he said.
“The conclusion was that a single dose of Pataday Extra Strength was significantly more efficacious than a single dose of Claritin in subjects with ocular itching in allergic conjunctivitis at both time points,” Weisbarth said.
“Pataday is OTC, so patients have more access to the product,” he added. “It’s one way we’re trying to enhance the way practitioners can serve their patients.”
