Acular, Acular PF, Acular LS, Acuvail

Func. class.:
Antiinflammatory (ophthalmic)

Nonsteroidal antiinflammatory drug

ACTION:

Inhibits miosis by inhibiting the biosynthesis of ocular prostaglandins; prostaglandins play a role in the miotic response produced during ocular surgery by constricting the iris sphincter independently of cholinergic mechanisms

USES:

Pain and inflammation after cataract surgery, refractive surgery, seasonal allergic conjunctivitis

CONTRAINDICATIONS:

Hypersensitivity to this product, sulfites, NSAIDs, salicylates

Precautions:
Bleeding disorders, complicated ocular surgery, corneal denervation, diabetes mellitus, rheumatoid arthritis, dry eye syndrome, pregnancy (C), breastfeeding, children, contact lens
