Toxicity Profile
Route of ExposureNot Available
Mechanism of ToxicityPhenacetin's analgesic effects are due to its actions on the sensory tracts of the spinal cord. In addition, phenacetin has a depressant action on the heart, where it acts as a negative inotrope. It is an antipyretic, acting on the brain to decrease the temperature set point. It is also used to treat rheumatoid arthritis (subacute type) and intercostal neuralgia.
MetabolismMetabolised in the body to paracetamol.
Toxicity ValuesAcute oral toxicity (LD50): 866 mg/kg [Mouse].
Lethal DoseNot Available
Carcinogenicity (IARC Classification)1, carcinogenic to humans. (5)
Uses/SourcesUsed principally as an analgesic.

Targets

General Function:
Prostaglandin-endoperoxide synthase activity
Specific Function:
Converts arachidonate to prostaglandin H2 (PGH2), a committed step in prostanoid synthesis. Involved in the constitutive production of prostanoids in particular in the stomach and platelets. In gastric epithelial cells, it is a key step in the generation of prostaglandins, such as prostaglandin E2 (PGE2), which plays an important role in cytoprotection. In platelets, it is involved in the generation of thromboxane A2 (TXA2), which promotes platelet activation and aggregation, vasoconstriction and proliferation of vascular smooth muscle cells.
