Published controlled studies on differences between men and women regarding pharmacokinetics, dosing and safety of sodium cromoglycate are lacking. The effect of sodium cromoglycate as a treatment for improving tear film break up time was in a small study shown to be better in women.

Additional information

Pharmacokinetics and dosing

No studies with a clinically relevant sex analysis regarding the pharmacokinetics or dosing of sodium cromoglycate have been found.


In a randomized study of sodium cromoglycate’s prolonging effect of tear film break up time in patients with an [abnormal tear film break-up] acute tear film break up phenomenon (13 men, 28 women) men had a lower increase in mean tear film break up time than women (39% vs 83%) [1]. Women have been shown to have a higher concentration of magnesium ions in their tear fluid [2]. A hypothesis to explain the better effect is that magnesium ions in tear fluid induce gelling of sodium cromoglycate thus creating a protective film [1].

Adverse effects

No studies with a clinically relevant sex analysis regarding the adverse effects of sodium cromoglycate have been found.
