A comparison of the efficacy and tolerability of olopatadine hydrochloride 0.1% ophthalmic solution and cromolyn sodium 2% ophthalmic solution in seasonal allergic conjunctivitis has found that Six weeks’ installation of olopatadine 0.1% ophthalmic solution two times a day had a significantly greater effect on the ocular signs and symptoms of allergic conjunctivitis compared with 6 weeks’ installation of cromolyn 2% (sodium Cromoglycate) ophthalmic solution 4 times a day dose. Both treatments were well tolerated by patients in all age groups; however, olopatadine appeared to have better local tolerability in children aged <11 years.
