Objective: Bixa orellana is a plant from the Bixaceae family, for which, limited information is available on hepatoprotective properties. This study aimed at evaluating the protective effects of this plant on sub-acute acetaminophen (APAP)-induced liver injury in mice. Materials and Methods: Various aqueous extracts were prepared from roots, leav...

Aspirin, nonsteroidal antiinflammatory drugs (NSAID), and acetaminophen are commonly used. Frequent use of analgesics has been associated with a higher risk of hearing loss. However, the association between duration of analgesic use and the risk of hearing loss is unclear. We investigated the relationship between duration of analgesic use and self-reported hearing loss among 55,850 women in the...

The mechanism of analgesic action of acetaminophen (paracetamol) remains unknown. However, a central component distinct from that of the NSAIDs (non-steroidal antiinflammatory drugs) seems likely. A recent report (NeuroReport 6:1546-1548, 1995) suggests the involvement of 5-HT3 receptors. In the present study, we measured the affinity of acetaminophen at 5-HT3, as well as 5-HT1A, 5-HT1B, 5-HT1D...
