Vicodin (Hydrocodone + Paracetamol/Acetaminophen) – Opioid Combination Analgesic (Rx, Controlled)
Vicodin is a combination analgesic containing hydrocodone (a semi-synthetic opioid) and paracetamol (acetaminophen). It is used for the management of moderate to severe pain when non-opioid treatments are not sufficient.
- Hydrocodone acts on μ-opioid receptors in the brain to reduce pain perception
- Paracetamol enhances analgesia through central pain inhibition
Together, they provide more effective pain relief than either component alone, but also increase risks such as sedation, dependence, and liver toxicity (from acetaminophen overdose).
