Latanoprost (pronounced la-TA-noe-prost) ophthalmic solution is a topical medication used for controlling the progression of glaucoma or ocular hypertension by reducing intraocular pressure. It is a prostaglandin analogue (more specifically an analogue of prostaglandin F[1]) that works by increasing the outflow of aqueous fluid from the eyes (through the uvealsclearal tract).[2] Latanoprost is an isopropyl ester prodrug, that is hydrolyzed by esterases in the cornea to the biologically active acid.[3]

It is also known by the brand name of Xalatan manufactured by Pfizer. Annual sales are approximately $1.6 billion. The patent for latanoprost expired in March 2011, and at least one generic version (manufactured by Mylan Inc.) is now widely available in the U.S. The Veterans Health Administration, part of the U.S. Department of Veterans Affairs, uses generic Latanoprost manufactured by Alcon Laboratories of Fort Worth, Texas distributed by Novartis generic brand Sandoz Pharmaceuticals.

Latanoprost was invented by Johan W. Stjernschantz and Bahram Resul, employees of the Pharmacia Corporation of Upsalla, Sweden. [4]

Adverse reactions[edit]

Possible side effects:

  • May eventually cause permanent darkening of the iris to brown (heterochromia);
  • May cause reddening of the eyes (hyperemia)
  • May cause blurred vision;
  • May cause eyelid redness;
  • May permanently darken eyelashes;
  • May cause eye discomfort;
  • May cause a temporary burning sensation during use.
  • May cause thickening of the eyelashes.(used,also bimatoprost,in cosmetic industry as eyelash growth enhancers)
  • Rarely, herpes simplex keratitis.
  • A single case report links latanoprost use to the progression of keratoconus.[5]
