| | Pranoprofen Usage And Synthesis |
| Chemical Properties | Off-White Solid | | Originator | Niflan, Yoshitomi ,Japan ,1981 | | Uses | Pranoprofen is an anti-inflammatory used in ophthalmology. | | Definition | ChEBI: Pranoprofen is a pyridochromene. | | Manufacturing Process | A mixture of 100 g of ethyl 2-cyano-2-(5H-[1]benzopyrano[2,3-b]-pyridin-7yl)propionate, 500 ml of glacial acetic acid and 200 g of concentrated hydrochloric acid is refluxed for 48 hours. The reaction mixture is concentrated, and the residue is dissolved in hot water. The solution is adjusted to pH 2 to 3 by addition of 10% sodium hydroxide. The resulting crystalline precipitate is washed thoroughly with water, and recrystallized from aqueous dioxane to give 74 g of 2-(5H-[1]benzopyrano[2,3-b]-pyridin-7yl)propionic acid as white crystals melting at 183°C to 183.5°C. | | Therapeutic Function | Analgesic, Antiinflammatory | | General Description | Pranoprofen is an arylalkanoic acid and a non-steroidal anti-inflammatory drug. | | Biochem/physiol Actions | Pranoprofen is used in eyes to treat chronic allergic conjunctivitis. It is also used as an anti-inflammatory and analgesic drug after strabismus surgery. |
