| Additional Infomation |
Dexamethasone acetate is a corticosteroid hormone.
Commonly known as decadron, dexamethasone acetate is a glucocorticosteroid previously marketed in the USA for the treatment of inflammatory respiratory, allergic, autoimmune, and other conditions. Developed in 1957, dexamethasone is structurally similar to other corticosteroids such as [hydrocortisone] and [prednisolone]. Dexamethasone acetate has largely been replaced by [dexamethasone] phosphate and continues to be administered for a large variety of inflammatory conditions. Recently, dexamethasone has been a drug of interest in the treatment of COVID-19. In a June 16 2020 press release highlighting early results of a clinical trial, Randomized Evaluation of COVID-19 Therapy (RECOVERY), it was reported that dexamethasone reduced COVID-19 deaths by approximately one-fifth and one-third in patients on oxygen therapy and mechanical ventilation, respectively. Dexamethasone was therefore recommended as a life-saving treatment for COVID-19 patients experiencing severe respiratory symptoms. |

Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples.
Injection Formulations
Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 ：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).

Injection Formulation 4: DMSO : 20% SBE-β-CD in saline = 10 : 90 [i.e. 100 μL DMSO → 900 μL (20% SBE-β-CD in saline)] Oral Formulations
Oral Formulation 1: Suspend in 0.5% CMC Na (carboxymethylcellulose sodium) Oral Formulation 2: Suspend in 0.5% Carboxymethyl cellulose Example: Take the Oral Formulation 1 (Suspend in 0.5% CMC Na) as an example, if 100 mL of 2.5 mg/mL working solution is to be prepared, you can first prepare 0.5% CMC Na solution by measuring 0.5 g CMC Na and dissolve it in 100 mL ddH2O to obtain a clear solution; then add 250 mg of the product to 100 mL 0.5% CMC Na solution, to make the suspension solution (2.5 mg/mL, ready for use in animals).

Oral Formulation 3: Dissolved in PEG400 (Please use freshly prepared in vivo formulations for optimal results.) |
| Preparing Stock Solutions | 1 mg | 5 mg | 10 mg | |
| 1 mM | 2.3015 mL | 11.5075 mL | 23.0150 mL | |
| 5 mM | 0.4603 mL | 2.3015 mL | 4.6030 mL | |
| 10 mM | 0.2301 mL | 1.1507 mL | 2.3015 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.
