🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works by blocking dopamine D2 receptors in the brain, particularly in the mesolimbic and mesocortical pathways. This blockade reduces the excessive dopaminergic signalling that contributes to hallucinations, delusions, and disorganised thinking. It also has some effect on sigma receptors and may influence serotonin and norepinephrine pathways, contributing to its sedative and anti-aggressive effects.
Mechanism Steps
💡 How to Take nedol liquid
Strength: Oral liquid, 2 mg per ml.
Dosage Information
| Adult Dosage | The dose of this medicine must be individualized by a qualified clinician based on the indication, age, weight, renal and hepatic function. For schizophrenia, a typical starting dose is 0.5 to 5 mg two to three times daily, with gradual titration. For acute agitation, doses may be higher under medical supervision. Always follow your doctor's prescription exactly. |
| Pediatric Dosage | Pediatric dosing is not established from available information. Consult a pediatrician. |
| Elderly Dosage | Elderly patients should start at a lower dose, typically half the adult dose, and titrate slowly. They are more susceptible to extrapyramidal symptoms, sedation, and cardiac effects. Close monitoring is required. |
| Renal Impairment | Dose adjustment may be needed in severe renal impairment. Consult your doctor. |
| Hepatic Impairment | Dose reduction may be necessary in patients with hepatic impairment. Monitor liver function and adjust dose as advised by your doctor. |
