Corticosteroids inhibit the inflammatory response to a variety of inciting agents and probably delay or slow healing. They inhibit the edema , fibrin deposition, capillary dilation, leukocyte migration, capillary proliferation, fibroblast proliferation, deposition of collagen , and scar formation associated with inflammation. There is no generally accepted explanation for the mechanism of action of ocular corticosteroids. However, corticosteroids are thought to act by the induction of phospholipase A2 inhibitory proteins, collectively called lipocortins. It is postulated that these proteins control the biosynthesis of potent mediators of inflammation such as prostaglandins and leukotrienes by inhibiting the release of their common precursor arachidonic acid.
Steroid and antibiotic eye drops - hydrocortisone/neomycin/polymixin B; loteprednol/tobramycin; prednisolone/gentamycin; prednisolone/sulfacetamide; hydrocortisone /neomycin/bacitracin/ polymyxin B (Blephamide, Catapred [discontinued], Isopto, Pred-G, Poly-Pred [discontinued], Tobradex, Zylet and many other brands) are steroid and antibiotic eye drops prescribed to prevent or treat eye infections that are associated with inflammation. Side effects, drug interactions, dosage, and pregnancy safety information should be reviewed prior to using these medications.
Oral exposure of female rats to 50 mg/kg/day of loteprednol etabonate from the start of the fetal period through the end of lactation, a maternally toxic treatment regimen (significantly decreased body weight gain), gave rise to decreased growth and survival and retarded development in the offspring during lactation; the NOEL for these effects was 5 mg/kg/day. Loteprednol etabonate had no effect on the duration of gestation or parturition when administered orally to pregnant rats at doses up to 50 mg/kg/day during the fetal period.
