Acular (Ketorolac trometamol 0.5% or 5gm per mL) (Minolac)
Ketorolac trometamol is a non-steroidal anti-inflammatory drug (NSAID) in the family of heterocyclic acetic acid derivative.
It is often used as an analgesic in preventing and reducing inflammation after eye surgery and relieving post-operative pain.
It works by blocking the production of certain chemicals that cause inflammation, pain, tenderness and swelling.
This medicine should only be used for three weeks at most. [Source]
Ketorolac acts by inhibiting the bodily synthesis of prostaglandins. It works by blocking the action of a substance in the body called cyclo-oxygenase (COX). Cyclo-oxygenase is involved in producing prostaglandins, in response to injury or certain diseases, such as arthritis. These prostaglandins cause pain, swelling and inflammation. Ketorolac trometamol blocks the production of these prostaglandins and so is effective at relieving pain and inflammation. [Source]
Eye-drops are used to treat eye pain and to relieve the itchiness and burning of seasonal allergies. The ophthalmic formulation can be used instead of steroidal anti inflammatories in cases where a raised intraocular pressure (glaucoma) is to be avoided. [Source]
The preservative benzalkonium chloride found in the eye drops. This is often a cause of dry eyes, so the drops should be avoided if possible.
In my case Acular did NOT work. Patanol behaved much much better, but there was no cure.
