Description

Benoxaprofen is a monocarboxylic acid that is propionic acid substituted at position 2 by a 2-(4-chlorophenyl)-1,3-benzoxazol-5-yl group. It was used as a non-steroidal anti-inflammatory drug until 1982 when it was withdrawn from the market due to adverse side-effects including liver necrosis, photosensitivity, and carcinogenicity in animals. It has a role as a non-steroidal anti-inflammatory drug, an EC 1.13.11.34 (arachidonate 5-lipoxygenase) inhibitor, an antipyretic, a non-narcotic analgesic, a protein kinase C agonist, a hepatotoxic agent, an antipsoriatic and a nephrotoxin. It is a member of 1,3-benzoxazoles, a monocarboxylic acid and a member of monochlorobenzenes. It derives from a propionic acid.|The use of benoxaprofen, formerly marketed as Oraflex tablets, was associated with fatal cholestatic jaundice among other serious adverse reactions. The holder of the approved application voluntarily withdrew Oraflex tablets from the market on August 5, 1982.

Poison by ingestion, subcutaneous, and intraperitoneal routes. Moderately toxic to humans by ingestion.Human systemic effects by ingestion: jaundice and gynecomastia (excessive development of the male mammary glands), changes in kidney tubules, decreased

Drug Information

MeSH：

Anti-inflammatory agents that are non-steroidal in nature. In addition to anti-inflammatory actions, they have analgesic, antipyretic, and platelet-inhibitory actions.They act by blocking the synthesis of prostaglandins by inhibiting cyclooxygenase, which converts arachidonic acid to cyclic endoperoxides, precursors of prostaglandins. Inhibition of prostaglandin synthesis accounts for their analgesic, antipyretic, and platelet-inhibitory actions; other mechanisms may contribute to their anti-inflammatory effects. (See all compounds classified as Anti-Inflammatory Agents, Non-Steroidal.)|Drugs used to treat or prevent skin disorders or for the routine care of skin. (See all compounds classified as Dermatologic Agents.)|Compounds that bind to and inhibit that enzymatic activity of LIPOXYGENASES. Included under this category are inhibitors that are specific for lipoxygenase subtypes and act to reduce the production of LEUKOTRIENES. (See all compounds classified as Lipoxygenase Inhibitors.)
