Biological Activity
| ln Vivo |
Ocular PK: After topical instillation of 1% hydrocortisone sodium phosphate eye drops (50 μL) in cataract patients, aqueous humor concentrations peaked at 30 min (Tₘₐₓ) with Cₘₐₓ = 23.8 ng/mL. AUC₀₋₁₂₀ was 1342 ng·min/mL. Elimination half-life = 46 min. Systemic absorption was negligible (plasma concentrations below detection limit).[1] In rats with acetic acid-induced stomach ulcers, hydrocortisone sodium phosphate (2.5 mg/kg, intraperitoneal injection, daily) can postpone the healing process [2]. |
| Animal Protocol |
Animal/Disease Models: Wistar rat [2] Doses: 2.5 mg/kg Route of Administration: 2.5 mg/kg, intraperitoneal (ip) injection, daily Experimental Results: Caused significant delay in healing of acetic acid-induced ulcers. |

| Toxicity/Toxicokinetics |
Subcutaneous injection of hydrocortisone sodium phosphate (50 mg/kg/day) in rats with acetic acid-induced gastric ulcers significantly delayed ulcer healing: Ulcer index increased to 129 ± 11 vs. 59 ± 7 in control (p<0.01). Caused severe mucosal damage with neutrophil infiltration and edema. Reduced body weight gain by 12% vs. control.[2] 441406 rat LD50 oral 6100 mg/kg Gekkan Yakuji.

| Additional Infomation |
Hydrocortisone sodium phosphate eye drops rapidly penetrate human cornea, achieving therapeutic concentrations in aqueous humor within 15 min post-instillation.[1] Concomitant administration of sucralfate/lansoprazole reversed the ulcer-healing impairment caused by hydrocortisone sodium phosphate in rats.[2] Cortisol sodium phosphate is an organic sodium salt that is the disodium salt of cortisol phosphate. It contains a cortisol phosphate(2-). |
Solubility Data
| Solubility (In Vitro) | May dissolve in DMSO (in most cases), if not, try other solvents such as H2O, Ethanol, or DMF with a minute amount of products to avoid loss of samples |
| Solubility (In Vivo) |
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 (e.g. IP/IV/IM/SC) Injection Formulation 1: DMSO : Tween 80: Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline) *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)] *Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution.

InvivoChem strongly recommends customers to read literature methods/protocols carefully before determining which formulation you should use for in vivo studies, as different compounds have different solubility properties and have to be formulated differently.  (Please use freshly prepared in vivo formulations for optimal results.) |
