🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionGabapentin is absorbed from the gastrointestinal tract via a saturable transport mechanism; bioavailability decreases as the dose increases. Nortriptyline is well absorbed from the gastrointestinal tract. Food does not significantly affect the absorption of either component.
DistributionGabapentin distributes widely throughout the body, including the central nervous system, with a volume of distribution of approximately 0.8 L/kg. Nortriptyline is highly lipophilic and distributes extensively into tissues, including the brain.
Protein BindingGabapentin is less than 3% bound to plasma proteins. Nortriptyline is approximately 90-95% bound to plasma proteins, primarily albumin and alpha-1-acid glycoprotein.
MetabolismGabapentin is not metabolized in humans and is excreted unchanged. Nortriptyline is metabolized in the liver primarily by CYP2D6 and to a lesser extent by CYP1A2, CYP2C19, and CYP3A4, producing active metabolites such as 10-hydroxynortriptyline.
Half-LifeGabapentin elimination half-life is 5-7 hours in patients with normal renal function. Nortriptyline elimination half-life ranges from 18-44 hours, with an average of about 26 hours.
ExcretionGabapentin is excreted unchanged in the urine by glomerular filtration. Nortriptyline and its metabolites are excreted primarily in the urine as glucuronide conjugates.
BioavailabilityGabapentin bioavailability is dose-dependent: approximately 60% at 300 mg, 47% at 600 mg, 34% at 1200 mg, and 33% at 1600 mg. Nortriptyline bioavailability is approximately 50-80% due to first-pass metabolism.
Onset of ActionGabapentin onset of action for neuropathic pain may take several days to weeks. Nortriptyline onset for pain relief is typically 1-2 weeks, with full effect after 4-6 weeks.
Peak Plasma TimeGabapentin peak plasma concentration occurs 2-3 hours after oral administration. Nortriptyline peak plasma concentration occurs 4-8 hours after oral administration.
Duration of ActionGabapentin duration of action is approximately 6-8 hours per dose. Nortriptyline duration of action is longer, up to 24 hours, allowing once-daily dosing.

How It Works

This medicine combines two active ingredients with complementary mechanisms. Gabapentin binds to the alpha-2-delta subunit of voltage-gated calcium channels in the central nervous system, reducing the release of excitatory neurotransmitters such as glutamate and substance P, which decreases neuronal excitability and pain transmission. Nortriptyline inhibits the reuptake of serotonin and norepinephrine at presynaptic neurons, increasing their availability in the synaptic cleft, which enhances descending inhibitory pain pathways and modulates mood. Together, they provide synergistic relief for neuropathic pain.

Mechanism Steps

1
Gabapentin binding to calcium channels: Gabapentin binds to the alpha-2-delta subunit of voltage-gated calcium channels on presynaptic neurons, reducing calcium influx and subsequent release of pain neurotransmitters.
2
Reduced neurotransmitter release: This leads to decreased release of glutamate, substance P, and norepinephrine, dampening pain signal transmission in the spinal cord and brain.
3
Nortriptyline inhibits reuptake: Nortriptyline blocks the reuptake of serotonin and norepinephrine at presynaptic nerve terminals, increasing their concentrations in the synaptic cleft.
4
Enhanced descending inhibition: Increased serotonin and norepinephrine enhance the activity of descending inhibitory pathways from the brainstem to the spinal cord, further reducing pain perception.
5
Synergistic analgesic effect: The combined actions of gabapentin and nortriptyline produce a greater reduction in neuropathic pain than either agent alone.

💡 How to Take arigaba nt tablet

Strength: Each tablet contains Gabapentin 400 mg and Nortriptyline 10 mg.

1Take this medicine orally with a glass of water.
2Swallow the tablet whole; do not crush or chew.
3Take with food to reduce stomach upset.
4Take at the same time each day to maintain consistent levels.
5Do not stop abruptly without consulting your doctor.

Dosage Information

Adult DosageThe usual adult dose is one tablet taken orally once or twice daily, or as directed by your physician. The dose may be adjusted based on your response and tolerability. Do not exceed the prescribed dose. 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 side effects of this medicine, especially dizziness, drowsiness, and confusion. Start with a lower dose and titrate slowly. Dose must be individualized by a qualified clinician based on renal and hepatic function.
Renal ImpairmentGabapentin requires dose adjustment in renal impairment. For creatinine clearance 30-59 mL/min, the maximum daily dose is 600 mg; for 15-29 mL/min, 300 mg; for <15 mL/min, 150 mg. Nortriptyline does not require renal dose adjustment but use with caution. Consult your doctor for personalized dosing.
Hepatic ImpairmentNortriptyline should be used with caution in patients with hepatic impairment. Dose reduction may be necessary. Gabapentin does not undergo hepatic metabolism, so no adjustment is needed for hepatic impairment alone. Consult your doctor for personalized dosing.
Maximum Daily DoseThe maximum daily dose of gabapentin is 3600 mg; nortriptyline is 150 mg. However, the maximum dose of this fixed-dose combination should not exceed the equivalent of gabapentin 1600 mg and nortriptyline 40 mg per day, or as prescribed by your doctor.
