Loteprednol etabonate (Lotemax; Alrex; HGP-1; Loterox; Locort; P-5604; HGP1; Lenoxin, CDDD-5604), the esther form of Loteprednol, is a potent glucocorticoid receptor agonist approved as a medication used in treatment of inflammation of the eye due to allergies. Loteprednol possesses a metabolically labile function, the 17beta-ester, that is designed to be rapidly deactivated in the systemic circulation. Loteprednol etabonate exhibits a binding affinity which is 4.3 times that of dexamethasone.

Dogs receiving 5 mg/kg of loteprednol etabonate intravenously show a 2.8 h terminal half-life, 3.7 L/kg volume of distribution, and 0.9 L/h/kg total body clearance. not found in the urine. Dogs received the medication orally (5 mg/kg), and the plasma solely contained metabolites—no intact drug—which suggests a substantial first-pass impact.

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (5.35 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 | 2.1416 mL | 10.7078 mL | 21.4156 mL | |
| 5 mM | 0.4283 mL | 2.1416 mL | 4.2831 mL | |
| 10 mM | 0.2142 mL | 1.0708 mL | 2.1416 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.
