Romilastine (3-300 μg/kg; subcutaneous injection; single dose 24-26 hours after irradiation; daily dose 1-3 days after irradiation; daily dose 1-5 days after irradiation) significantly improved 30-day survival by about 40% when administered as a single subcutaneous dose of 30 or 100 μg/kg 24 hours after 6.8 Gy whole-body irradiation, and accelerated platelet recovery. Repeated administration or combined administration with pegfilgrastim did not provide any additional benefit [1].

Animal/Disease Models:C57BL/6J (male and female, 11-12 weeks old, whole-body irradiation with 6.8 Gy X-rays) [1]
Doses: 3 μg/kg; 10 μg/kg; 30 μg/kg; 100 μg/kg; 300 μg/kg Route of Administration: Subcutaneous injection; single dose 24-26 hours after irradiation; daily dose for days 1-3 after irradiation; daily dose for days 1-5 after irradiation Experimental Results: 30-day survival rate was 41% (single dose of 3 μg/kg, 6.8 Gy model). 30-day survival rate was 38% (single dose of 10 μg/kg, 6.8 Gy model). 30-day survival rate was 57% (single dose of 30 μg/kg, 6.8 Gy model). The 30-day survival rate was 52% (single dose of 100 μg/kg, 6.8 Gy model). The 30-day survival rate was 71% (single dose of 30 μg/kg, 6.8 Gy non-hemorrhagic group). |

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.) |
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.
