Pranoprofen is a non-steroidal anti-inflammatory drug used in ophthalmology. Target: PGE2Pranoprofen 0.1% was found to be as effective as diclofenac sodium 0.1% in reducing inflammation and pain after strabismus surgery. Pranoprofen could be used as a safe and effective anti-inflammatory alternative for the treatment of inflammation following strabismus surgery [1]. pranoprofen has efficacy equivalent to a moderate-potency corticosteroid with a better safety profile. It should be considered for the treatment of chronic conjunctivitis of presumed nonbacterial origin [2]. Pranoprofen inhibited ER stress-induced glucose regulated protein 78 (GRP78) expression, an ER-localized molecular chaperon. Moreover, pranoprofen inhibited ER stress-induced CCAAT/enhancer-binding protein homologous protein (CHOP) expression, an apoptotic transcription factor. the inhibitory effect of pranoprofen on ER stress-related genes (GRP78 and CHOP) would be mediated through the inhibition of XBP-1 splicing [3].
