pethidine + haloperidol

Pethidine + haloperidol is a combination of two pharmaceutical drugs, pethidine (also known as meperidine) and haloperidol. Pethidine is an opioid analgesic primarily used for the relief of moderate to severe pain, acting mainly as a mu-opioid receptor agonist to inhibit pain signaling in the central nervous system. Haloperidol is a first-generation (typical) antipsychotic that acts predominantly as an antagonist at dopamine D2 receptors in the brain, reducing dopaminergic neurotransmission and thereby exerting antipsychotic and antiemetic effects[1][3][5]. The combination has been used off-label for its sedative properties, particularly in settings such as palliative care or during childbirth to manage agitation, anxiety, or nausea alongside pain control. The sedative effects of both drugs are potentiated when combined, which can increase both efficacy and risk[9].
