Indication |
For the treatment of postoperative inflammation following ocular surgery and in the treatment of anterior uveitis. |
Pharmacodynamics |
Rimexolone is a glucocorticoid corticosteroid for systemic use.
Corticosteroids suppress the inflammatory response to a variety of
inciting agents of a mechanical, chemical, or immunological nature. They
inhibit edema, cellular infiltration, capillary dilatation,
fibroblastic proliferation, deposition of collagen and scar formation
associated with inflammation. |
Mechanism of action |
Rimexolone is a glucocorticoid receptor agonist. The
antiinflammatory actions of corticosteroids are thought to involve
lipocortins, phospholipase A2 inhibitory proteins which, through
inhibition of arachidonic acid, control the biosynthesis of
prostaglandins and leukotrienes. By binding to the glucocorticoid
receptor, this drug ultimately leads to changes in genetic transcription
involving the lipocortins and prostaglandins. |
Absorption |

Metabolism |
Undergoes extensive metabolism. Following intravenous
administration of radiolabeled rimexolone in rats, more than 80% of the
dose was excreted in the feces as rimexolone and metabolites.
Metabolites have been shown to be either less active than rimexolone or
inactive in human glucocorticoid receptor binding assays. |
Route of elimination |
Following IV administration of radio-labelled rimexolone to rats,
greater than 80% of the dose is excreted via the feces as rimexolone and
metabolites. |
Half life |
The serum half-life of rimexolone could not be reliably estimated
due to the large number of samples below the quantitation limit of the
assay (80 pg/mL). However, based on the time required to reach
steady-state, the half-life appears to be short (1-2 hours). |
Clearance |
Not Available |
Toxicity |
Symptoms of overdose include retinal toxicity, glaucoma, and subcapsular cataract. |
