🇮🇳 gabathica nt 100mg/10mg tablet के बारे में (Hindi Summary)

उपयोग: यह दवा गैबापेंटिन और नॉर्ट्रिप्टिलाइन का संयोजन है, जिसका उपयोग न्यूरोपैथिक दर्द (तंत्रिका दर्द) के इलाज के लिए किया जाता है। यह मधुमेह से होने वाले तंत्रिका दर्द, दाद के बाद होने वाले दर्द, और अन्य तंत्रिका संबंधी दर्द में राहत देती है। यह दवा दर्द के संकेतों को कम करके और मस्तिष्क में दर्द को नियंत्रित करने वाले रसायनों को बढ़ाकर काम करती है। इसे आमतौर पर रात में सोने से पहले लिया जाता है।

साइड इफेक्ट्स: इस दवा के सामान्य दुष्प्रभावों में नींद आना, चक्कर आना, मुँह सूखना, कब्ज, और वजन बढ़ना शामिल हैं। कुछ लोगों को धुंधली दृष्टि, मतली, या सिरदर्द भी हो सकता है। गंभीर दुष्प्रभाव दुर्लभ हैं, लेकिन यदि आपको आत्महत्या के विचार, गंभीर एलर्जी, या दिल की धड़कन में अनियमितता महसूस हो, तो तुरंत डॉक्टर से संपर्क करें।

सुरक्षा सलाह: इस दवा को डॉक्टर के बताए अनुसार ही लें। इसे अचानक बंद न करें, क्योंकि इससे withdrawal के लक्षण हो सकते हैं। शराब और अन्य नींद लाने वाली दवाओं से बचें। गाड़ी चलाने या मशीन चलाने से बचें जब तक आपको पता न चल जाए कि यह दवा आप पर कैसे असर करती है। यदि आप गर्भवती हैं या स्तनपान करा रही हैं, तो डॉक्टर को बताएं।

🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionGabapentin is absorbed from the gastrointestinal tract via a saturable transport mechanism. 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. 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.
MetabolismGabapentin is not significantly 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.
Half-LifeThe elimination half-life of gabapentin is approximately 5 to 7 hours. The elimination half-life of nortriptyline ranges from 18 to 44 hours, with an average of about 25 hours.
ExcretionGabapentin is excreted unchanged in the urine. Nortriptyline and its metabolites are excreted primarily in the urine and to a lesser extent in feces.
BioavailabilityThe bioavailability of gabapentin is dose-dependent and decreases as the dose increases; it is approximately 60% at 900 mg/day, 40% at 1200 mg/day, and 35% at 2400 mg/day. The bioavailability of nortriptyline is approximately 50% due to first-pass metabolism.
Onset of ActionPain relief from gabapentin may begin within 1 to 2 weeks, but full effect can take 3 to 4 weeks. Nortriptyline's antidepressant and analgesic effects may take 2 to 4 weeks to become noticeable.
Peak Plasma TimeGabapentin reaches peak plasma concentrations within 2 to 3 hours after oral administration. Nortriptyline reaches peak plasma concentrations within 6 to 8 hours.
Duration of ActionThe analgesic effect of this combination is sustained with regular dosing. Gabapentin's effect lasts approximately 6 to 8 hours per dose, while nortriptyline's effect is longer due to its longer half-life.

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 helps stabilize hyperexcited neurons. Nortriptyline inhibits the reuptake of norepinephrine and serotonin at nerve terminals, increasing their availability in the synaptic cleft and enhancing descending inhibitory pain pathways. Together, they reduce abnormal pain signaling and perception.

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 excitatory neurotransmitters.
2
Reduced neuronal excitability: By decreasing neurotransmitter release, gabapentin stabilizes hyperexcited nerve cells, which helps control neuropathic pain and seizures.
3
Nortriptyline inhibits reuptake: Nortriptyline blocks the reuptake of serotonin and norepinephrine, increasing their concentrations in the synaptic cleft.
4
Enhanced descending inhibition: Increased serotonin and norepinephrine enhance the brain's descending inhibitory pathways that dampen pain signals coming from the spinal cord.
5
Combined analgesic effect: The two mechanisms work together to reduce both the generation and perception of neuropathic pain.

💡 How to Take gabathica nt 100mg/10mg tablet

Strength: Each tablet contains gabapentin 100 mg and nortriptyline 10 mg.

1Take this medicine orally with a glass of water.
2You can take it with or without food, but taking it with food may reduce stomach upset.
3Swallow the tablet whole; do not crush, chew, or break it.
4Take it at the same time each day to maintain consistent blood levels.
5If you are taking it once daily, take it at bedtime to minimize daytime drowsiness.
6Do not stop taking this medicine suddenly without consulting your doctor.

Dosage Information

Adult DosageThe usual starting dose for adults is one tablet taken orally once daily, preferably at bedtime to minimize daytime drowsiness. The dose may be gradually increased by your doctor based on your response and tolerability. The maximum recommended dose is typically one tablet twice daily, but this must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function. Do not adjust the dose without consulting your doctor.
Pediatric DosagePediatric dosing is not established from available information. Consult a pediatrician.
Elderly DosageElderly patients (above 65 years) may be more sensitive to the side effects of this medicine, especially drowsiness, dizziness, and anticholinergic effects. Start with a lower dose and titrate slowly. Renal function should be assessed before initiating therapy, and dose adjustments may be necessary.
Renal ImpairmentGabapentin requires dose reduction in patients with impaired renal function. For creatinine clearance 30-59 mL/min, the dose may be reduced; for 15-29 mL/min, further reduction; for <15 mL/min, use is not recommended unless on dialysis. Nortriptyline does not require renal dose adjustment, but caution is advised. Consult your doctor for personalized dosing.
Hepatic ImpairmentNortriptyline should be used with caution in patients with hepatic impairment, as it is extensively metabolized in the liver. Dose reduction may be necessary. Gabapentin does not undergo significant hepatic metabolism, so no adjustment is needed for hepatic impairment alone.
Maximum Daily DoseThe maximum daily dose of this combination is generally one tablet twice daily (i.e., gabapentin 200 mg and nortriptyline 20 mg per day). However, the exact maximum dose must be determined by a qualified clinician based on individual patient factors.
