| Additional Infomation |
Tranilast is an amidobenzoic acid that is anthranilic acid in which one of the anilino hydrogens is replaced by a 3,4-dimethoxycinnamoyl group. It has a role as an anti-asthmatic drug, a nephroprotective agent, an anti-allergic agent, a calcium channel blocker, an antineoplastic agent, an aryl hydrocarbon receptor agonist and a hepatoprotective agent. It is a member of cinnamamides, a dimethoxybenzene, an amidobenzoic acid and a secondary carboxamide. It is functionally related to an anthranilic acid. Tranilast is an antiallergic drug developed by Kissei Pharmaceuticals. In 1982, it was approved in Japan and South Korea for the management of bronchial asthma. Indications for keloid and hypertrophic scar were added in 1993. It has been used for the treatment of allergic disorders such as asthma, allergic rhinitis and atopic dermatitis. Drug Indication For the treatment of bronchial asthma, keloid and hypertrophic scar, and allergic disorders such as asthma, allergic rhinitis and atopic dermatitis. |
Solubility Data
| Solubility (In Vitro) |
DMSO: 65~100 mg/mL (198.6~305.5 mM) Ethanol: ~4 mg/mL |
| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (7.64 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (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 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.5 mg/mL (7.64 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.) |
