Xalacom consists of two components: latanoprost and timolol maleate. These two components decrease elevated intraocular pressure (IOP) by different mechanisms of action.
SIDE-EFFECTS, SPECIAL PRECAUTIONS AND INTERACTIONS:
The adverse events of Xalacom™ are similar to those reported earlier for latanoprost and timolol.
Based on evidence from consecutive photographs, increased iris pigmentation was seen in 16-20% of all patients who received Xalacom™ eye drops for up to one year.
Onset of action of Xalacom™ is within one hour, and maximal effect occurs within six to eight hours. IOP reducing effect has been shown to be present up to 24 hours post dosage after multiple treatments.
