DRUG INTERACTIONS
Carcinogenesis, Mutagenesis, Impairment of Fertility
Latanoprost was not mutagenic in bacteria, in mouse lymphoma or in mouse micronucleus tests.
Chromosome aberrations were observed in vitro with human lymphocytes.
Latanoprost was not carcinogenic in either mice or rats when administered by oral gavage at doses of up to 170 µg/kg/day (approximately 2,800 times the recommended maximum human dose) for up to 20 and 24 months, respectively.
Additional in vitro and in vivo studies on unscheduled DNA synthesis in rats were negative. Latanoprost has not been found to have any effect on male or female fertility in animal studies.
Pregnancy
Teratogenic Effects
Pregnancy Category C
Reproduction studies have been performed in rats and rabbits. In rabbits an incidence of 4 of 16 dams had no viable fetuses at a dose that was approximately 80 times the maximum human dose, and the highest nonembryocidal dose in rabbits was approximately 15 times the maximum human dose. There are no adequate and well-controlled studies in pregnant women. XALATAN should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
