title: Leukotriene antagonist S 872419 A for early-phase treatment of chemical burn in the rabbit eye.
abstract: S 872419 A, a specific receptor antagonist of peptide leukotrienes, was tested in the early-phase treatment of chemically burned eye (0.25 mol/l sodium hydroxide) of the rabbit. The drug was topically applied 5 times a day in a 1% solution, controls were the untreated opposite eye. Gross and microscopic investigations indicated that S 872419 A inhibits the inflammatory response of the chemically burned anterior eye segment. The parameters of healing considered (epithelial regeneration, corneal clouding and swelling, infiltration with polymorphonuclear leukocytes) suggest inhibition of lipoxygenase-mediated reactions in the tissue. PGF2 alpha levels were the same in aqueous humour of treated and untreated eyes. Further experiments with S 872419 A and other nonsteroidal drugs should improve the anti-inflammatory therapy of the chemically burned eye.
