🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionParacetamol is rapidly and almost completely absorbed from the gastrointestinal tract after oral administration. Promethazine is also well absorbed orally, but its bioavailability may be reduced due to first-pass metabolism.
DistributionParacetamol distributes widely into most body tissues, with relatively low protein binding. Promethazine is highly protein-bound and distributes extensively into tissues, including the central nervous system.
Protein BindingParacetamol is approximately 10-25% bound to plasma proteins. Promethazine is about 93% bound to plasma proteins.
MetabolismParacetamol is primarily metabolized in the liver via glucuronidation and sulfation, with a small fraction metabolized by cytochrome P450 2E1 to a toxic intermediate, N-acetyl-p-benzoquinone imine (NAPQI), which is detoxified by glutathione. Promethazine is metabolized in the liver, primarily by CYP2D6, to various metabolites.
Half-LifeThe elimination half-life of paracetamol is about 2-3 hours in adults. Promethazine has a half-life of approximately 10-19 hours.
ExcretionParacetamol metabolites are excreted primarily in the urine. Promethazine metabolites are excreted in urine and feces.
BioavailabilityParacetamol has a high oral bioavailability, around 80-100%. Promethazine oral bioavailability is approximately 25% due to first-pass metabolism.
Onset of ActionOnset of action for paracetamol is within 30-60 minutes; for promethazine, sedation and antiemetic effects may occur within 20-60 minutes.
Peak Plasma TimeParacetamol peak plasma concentration occurs within 0.5-2 hours. Promethazine peak plasma levels are reached in about 2-3 hours.
Duration of ActionParacetamol effects last about 4-6 hours. Promethazine effects can last 6-8 hours or longer.

How It Works

This medicine combines two active ingredients with distinct mechanisms. Paracetamol acts primarily in the central nervous system by inhibiting prostaglandin synthesis, which reduces pain and fever. Promethazine is a phenothiazine antihistamine that blocks histamine H1 receptors, leading to reduced allergic responses and sedation. It also has anticholinergic and antiemetic effects, which help with nausea and vomiting.

Mechanism Steps

1
Paracetamol inhibits prostaglandin synthesis: Paracetamol reduces the production of prostaglandins in the brain, which are involved in pain and fever pathways.
2
Promethazine blocks histamine H1 receptors: Promethazine competes with histamine for H1 receptor sites, preventing histamine-mediated allergic symptoms.
3
Promethazine exhibits anticholinergic effects: It blocks muscarinic receptors, which contributes to its antiemetic and sedative properties.
4
Combined central nervous system depression: Both ingredients contribute to sedation, enhancing the overall calming effect.

Dosage Information

Adult DosageThe adult dosage of this medicine varies depending on the indication and patient factors. Typically, 5-10 mL of the suspension may be taken every 4-6 hours as needed for pain, fever, or allergic symptoms, but the maximum daily dose should not exceed the equivalent of 4 grams of paracetamol. Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function.
Pediatric DosagePediatric dosing is not established from available information. Consult a pediatrician.
Elderly DosageElderly patients may be more sensitive to the sedative and anticholinergic effects of promethazine. Start with a lower dose and monitor closely. Dose must be individualized by a qualified clinician.
Renal ImpairmentUse with caution in patients with renal impairment. Dose adjustment may be necessary. Consult a healthcare provider.
Hepatic ImpairmentUse with caution in patients with hepatic impairment. Paracetamol dose should be reduced, and liver function should be monitored. Consult a healthcare provider.
Maximum Daily DoseThe maximum daily dose of paracetamol should not exceed 4 grams (4000 mg) for adults. The maximum daily dose of promethazine varies but typically should not exceed 100-150 mg per day. Do not exceed the prescribed dose.
