In 48 hours, ketorolac (RS37619) salt (0–30 μM) efficiently destroys oral cancer cells [4]. In H357 cells, ketorolat (0–5 μM; 48 h) causes apoptosis and suppresses the production of the DDX3 protein [4]. The growth of oral cancer cells is inhibited by ketorolat (0-2.5 μM; 0-16 hours) [4]. Ketorolat (0-50 μM) decreases ATPase activity by directly interacting with DDX3 [4].

| ln Vivo |
Rabbits treated with ketorolac (RS37619) (0.4% Ketorolac Tromethamine Eye Drops) demonstrated strong ocular anti-inflammatory effects [1]. There are no negative effects of ketorolac (4 mg/kg/day orally; 2 weeks) on the volume fraction of trabecular bone formed in the rats' alveolar sockets [2]. In rats, intrathecal injection of ketorolac (60 μg) once reduces damage from spinal cord ischemia [3]. Oral cancer incidence in mice is decreased by ketorolat (20 and 30 mg/kg; intraperitoneal injection; twice weekly for 3 weeks) [4].

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).

*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.
