| ORPHENADRINE HYDROCHLORIDE Usage And Synthesis |
| Chemical Properties | White or almost white, crystalline powder. | | Uses | Antihistaminic;H1 antogonist | | Definition | ChEBI: A hydrochloride comprising equimolar amounts of ophenadrine and hydrogen chloride. | | General Description | Odorless white or almost white crystalline powder. pH (aqueous solution) about 5.5. Bitter numbing taste. | | Air & Water Reactions | May be sensitive to prolonged exposure to light and air. Water soluble. | | Reactivity Profile | ORPHENADRINE HYDROCHLORIDE is incompatible with strong oxidizers. | | Fire Hazard | Flash point data for ORPHENADRINE HYDROCHLORIDE are not available; however, ORPHENADRINE HYDROCHLORIDE is probably combustible. | | Biochem/physiol Actions | Muscarinic receptor antagonist; H1 histamine receptor antagonist; muscle relaxant. Orphenadrine has also been reported to inhibit the noradrenergic transporter and to block the NMDA receptor ion channel. | | Clinical Use | Anti-muscarinic:
Parkinsonism
Drug induced extra-pyramidal symptoms | | Safety Profile | Poison by ingestion, intravenous, intraperitoneal, and subcutaneous routes. Human systemic effects: mydriasis @updlaryd ilation), hallucinations, distorted perceptions, pulse rate increase, intracranial pressure increase. An experimental teratogen. Experimental reproductive effects. When heated to decomposition it emits toxic fumes of NOx and HCl | | Drug interactions | Potentially hazardous interactions with other drugs
None known | | Metabolism | Orphenadrine is almost completely metabolised to at least
8 metabolites in the liver.
It is mainly excreted in the urine as metabolites and small
amounts of unchanged drug |
