Aqueous penetration of topical tacrolimus.


ABSTRACT: Purpose:To evaluate the penetration of topical tacrolimus 0.05% into the aqueous humor. Observations:A total of four patients scheduled for routine cataract surgery were included prospectively. We excluded patients with corneal pathology or ocular surface diseases. Topical tacrolimus 0.05% was compounded at our facility. It was dosed every 1 min for 5 min an hour before the aqueous was sampled. Aqueous samples were collected at the time of cataract surgery and were subjected to detection of presence and level of tacrolimus. There were 2 male and 2 female patients. The age range was 58-73 years with a mean age of 66 years. Tacrolimus was detected in the aqueous humor in all patients. The concentration of tacrolimus in the aqueous ranged from 2.6 to 5.6 ng/ml (mean 4.15 ± 1.18 ng/ml). In all patients, the aqueous tacrolimus concentration was greater than the minimal therapeutic level. The study was registered at clinicaltrials.gov (registration number is NCT02794610). Conclusions and Importance:Tacrolimus was detected in the aqueous humor following topical application. Topical tacrolimus may be a promising steroid-sparing modality for the treatment of anterior uveitis.
