🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works through two complementary mechanisms. Pregabalin binds to the alpha-2-delta subunit of voltage-gated calcium channels in the central nervous system, which reduces the release of excitatory neurotransmitters such as glutamate, substance P, and noradrenaline. This dampens abnormal pain signaling from damaged nerves. Nortriptyline inhibits the reuptake of serotonin and noradrenaline in the brain and spinal cord, which strengthens descending pain-inhibitory pathways and helps modulate the perception of pain. The combination is thought to provide broader neuropathic pain relief than either ingredient alone.
Mechanism Steps
💡 How to Take neurazen g tablet
Strength: This medicine is available as an immediate-release oral tablet. The specific strength of Pregabalin and Nortriptyline in this product is not established from the available information. Always check the label on your pack for the exact strength prescribed to you.
Dosage Information
| Adult Dosage | The dose of this medicine must be individualized by a qualified clinician based on the indication, age, weight, kidney function, liver function, and response to treatment. In general, treatment is started at a low dose and increased gradually to reduce side effects. The usual adult dose is one tablet taken orally once or twice daily, often with the larger dose at bedtime to reduce daytime drowsiness. Do not change the dose without medical advice. Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function. |
| Pediatric Dosage | Pediatric dosing is not established from available information. Consult a pediatrician. |
| Elderly Dosage | Older adults are more sensitive to the side effects of this medicine, especially drowsiness, dizziness, confusion, falls, urinary retention, and low blood pressure. Treatment should usually be started at a lower dose and increased more slowly. Kidney function should be checked before and during treatment, and the dose should be adjusted accordingly. Regular review by a doctor is recommended. |
| Renal Impairment | Pregabalin is eliminated by the kidneys, so the dose of this medicine may need to be reduced in patients with kidney impairment. The exact adjustment depends on the measured kidney function and must be determined by a qualified clinician. Nortriptyline does not usually require dose adjustment for kidney function alone, but caution is advised. Patients with kidney disease should have their kidney function monitored regularly. |
| Hepatic Impairment | Nortriptyline is metabolized in the liver, so patients with liver impairment may need a lower dose and careful monitoring. Pregabalin is not significantly metabolized by the liver. The exact dose adjustment must be determined by a qualified clinician based on the severity of liver disease and clinical response. |
| Maximum Daily Dose | The maximum daily dose of this medicine must be determined by a qualified clinician based on the individual patient's condition, kidney function, and tolerability. Do not exceed the dose prescribed by your doctor. Taking more than the prescribed dose can increase the risk of serious side effects. |
