Latanoprost or Xalatan is a prostaglandin eye drop used in glaucoma therapy.
Latanoprost or Xalatan reduces intraocular pressure, that is the pressure inside the eye ball. It increases fluid drainage from the eye ball, and works as well as timolol does.
Latanoprost or Xalatan turns light coloured eyes brown by increasing the pigment in the iris. This change seems to be permanent.
It is generally well tolerated, however burning, stinging, a foreign body sensation, and blurred vision have been reported.
Latanoprost or Xalatan is an "add on" therapy, and people who use it may not be able to tolerate other eye drops. It is expensive.
If two or more eye drops are being used at one time, about a 5 minute wait between drops should be used to avoid washing the first drop out with the second drop.
