Fluorometholone (also known as NSC 47438) is a synthetic corticosteroid, commonly used as eye drops in the treatment of steroid responsive inflammatory conditions of the eye. Hourly topical administration of the drug suspension produces an average reduction of 46.8% in the polymorphonuclear leukocytes invading the corneal stroma. In the cornea, fluorometholone acetate appears to have a greater efficacy, as compared to fluorometholone alcohol, for reducing the number of leukocytes invading that tissue following an inflammatory stimulus.
ln Vitro |
Fluorometholone (25-100 nM; 12 hours, 24 hours) activates glucocorticoid receptors in conjunctival and corneal epithelial cells, increasing the expression of the MUC1, MUC4, MUC16, and MUC19 genes [1].

Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (6.64 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly.  (Please use freshly prepared in vivo formulations for optimal results.) |
Preparing Stock Solutions | 1 mg | 5 mg | 10 mg | |
1 mM | 2.6563 mL | 13.2813 mL | 26.5625 mL | |
5 mM | 0.5313 mL | 2.6563 mL | 5.3125 mL | |
10 mM | 0.2656 mL | 1.3281 mL | 2.6563 mL |
*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
Calculation results
Working concentration: mg/mL;
Method for preparing DMSO stock solution: mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation::Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O,mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
