is gabapentin a maintenance drug

Proportion of Responders (patients with ≥50% reduction in pain score) at Endpoint: Controlled PHN Studies. Controlled PHN Studies: Duration, Dosages, and Number of Patients. Additional reactions reported from the post-marketing experience are included as frequency 'Not known' (cannot be estimated from the available data) in italics in the list below. Gabapentin Accord-UK capsules contain lactose. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy. There were four suicides in drug-treated patients in the trials and none in placebo-treated patients, but the number is too small to allow any conclusion about drug effect on suicide.

Gabapentin pharmacokinetics are not affected by repeated administration. Because the effect on the breast-fed infant is unknown, caution should be exercised when gabapentin is administered to a breast-feeding mother.

• difficulty with speaking • double vision

Signs and symptoms in reported cases have included difficulty breathing, swelling of the lips, throat, and tongue, and hypotension requiring emergency treatment. Renal excretion of gabapentin is unaltered by probenecid.

In nonclinical studies in mice, rats, and rabbits, Gabapentin was developmentally toxic (increased fetal skeletal and visceral abnormalities, and increased embryofetal mortality) when administered to pregnant animals at doses similar to or lower than those used clinically [ see Data]. Gabapentin is a prescription medicine used to treat: Dosages up to 4800mg/day have been well tolerated in long-term open-label clinical studies. b To be administered as 300 mg every other day. Gabapentin is indicated as monotherapy in the treatment of partial seizures with and without secondary generalization in adults and adolescents aged 12 years and above. Gabapentin partially reduces responses to the glutamate agonist N-methyl-D-aspartate (NMDA) in some test systems in vitro, but only at concentrations greater than 100 μM, which are not achieved in vivo. Dosages up to 2400 mg/day have been well tolerated in long-term clinical studies.

Behaviors of concern should be reported immediately to healthcare providers. Granules India Limited. In vitro studies have shown that Gabapentin binds with high-affinity to the α2δ subunit of voltage-activated calcium channels; however, the relationship of this binding to the therapeutic effects of Gabapentin is unknown.

There are spontaneous and literature case reports of respiratory depression and/or sedation associated with gabapentin and opioid use.

Although no formal analysis by gender has been performed, estimates of response (Response Ratio) derived from clinical trials (398 men, 307 women) indicate no important gender differences exist. • swollen glands that do not go away There were several response ratio comparisons that showed a statistically significant advantage for Gabapentin compared to placebo and favorable trends for almost all comparisons. Although there is no evidence of rebound seizures with gabapentin, abrupt withdrawal of anticonvulsants in epileptic patients may precipitate status epilepticus (see section 4.2). The types and incidence of adverse reactions were similar across age groups except for peripheral edema and ataxia, which tended to increase in incidence with age. In elderly patients, and in patients with impaired renal function, gabapentin plasma clearance is reduced. Patients should be instructed to discontinue gabapentin and seek immediate medical care should they experience signs or symptoms of anaphylaxis (see section 4.8).

The therapy may be initiated by titrating the dose as described in Table 1. Gabapentin is not bound to plasma proteins and has a volume of distribution equal to 57.7 litres. If a patient requires dosing longer than 5 months for the treatment of peripheral neuropathic pain, the treating physician should assess the patient's clinical status and determine the need for additional therapy. Antacid (Maalox®) containing magnesium and aluminum hydroxides reduced the mean bioavailability of Gabapentin (N=16) by about 20%. The adverse reactions most commonly associated with withdrawal in patients >12 years of age were somnolence (1.2%), ataxia (0.8%), fatigue (0.6%), nausea and/or vomiting (0.6%), and dizziness (0.6%). Distribution Among the Gabapentin-treated patients, most of the reactions were mild to moderate in intensity. Gabapentin elimination half-life averaged 4.7 hours and was similar across the age groups studied. During the controlled trials in patients with post-herpetic neuralgia, somnolence and dizziness were reported at a greater rate compared to placebo in patients receiving Gabapentin, in dosages up to 3600 mg per day: i.e., 21% in Gabapentin-treated patients versus 5% in placebo-treated patients for somnolence and 28% in Gabapentin-treated patients versus 8% in placebo-treated patients for dizziness. False positive readings may be obtained in the semi-quantitative determination of total urine protein by dipstick tests. A meta-analysis of randomised placebo controlled trials of anti-epileptic drugs has also shown a small increased risk of suicidal ideation and behaviour.


Evidence of effectiveness was obtained in three trials conducted in 705 patients (age 12 years and above) and one trial conducted in 247 pediatric patients (3 to 12 years of age). The most significant of these can be classified into the following categories: 1) emotional lability (primarily behavioral problems), 2) hostility, including aggressive behaviors, 3) thought disorder, including concentration problems and change in school performance, and 4) hyperkinesia (primarily restlessness and hyperactivity). Postherpetic Neuralgia. Responder rate was higher in the Gabapentin 1200 mg/day group (16%) than in the placebo group (8%), but the difference was not statistically significant.

Administer Gabapentin orally with or without food. A slight decrease in renal excretion of gabapentin that is observed when it is coadministered with cimetidine is not expected to be of clinical importance. In accordance with current clinical practice, if gabapentin has to be discontinued it is recommended this should be done gradually over a minimum of 1 week independent of the indication. The effectiveness of Gabapentin as adjunctive therapy (added to other antiepileptic drugs) was established in multicenter placebo-controlled, double-blind, parallel-group clinical trials in adult and pediatric patients (3 years and older) with refractory partial seizures.

A statistically significant difference in responder rate was seen in the Gabapentin 900 mg/day group (22%) compared to that in the placebo group (10%). The mechanism of this risk is not known and the available data do not exclude the possibility of an increased risk for Gabapentin.

Gabapentin treatment has been associated with dizziness and somnolence, which could increase the occurrence of accidental injury (fall).

Therefore patients should be monitored for signs of suicidal ideation and behaviours and appropriate treatment should be considered. drug-seeking behaviour, dose escalation, development of tolerance. Slower titration of gabapentin dosage may be appropriate for individual patients. The background risk of major birth defects and miscarriage for the indicated population is unknown. There is no effect on fertility in animal studies (see section 5.3). Do not use Gabapentin for a condition for which it was not prescribed.

The mean Gabapentin half-life ranged from about 6.5 hours (patients with creatinine clearance >60 mL/min) to 52 hours (creatinine clearance <30 mL/min) and Gabapentin renal clearance from about 90 mL/min (>60 mL/min group) to about 10 mL/min (<30 mL/min).

• tremor • unusual eye movement In rats, increases in the incidence of pancreatic acinar cell adenoma and carcinoma were found in male rats receiving the highest dose (2000 mg/kg), but not at doses of 250 or 1000 mg/kg/day. Store Gabapentin at 20°C to 25°C (68°F to 77°F); excursions permitted from 15°C to 30°C (59°F to 86°F) [see USP Controlled Room Temperature]. Gabapentin is not appreciably metabolized nor does it interfere with the metabolism of commonly co-administered antiepileptic drugs [see Clinical Pharmacology (12.3)]. • are pregnant or plan to become pregnant. Gabapentin pharmacokinetic parameters without and with probenecid were comparable.

Valproic Acid

A slight decrease in renal excretion of gabapentin that is observed when it is coadministered with cimetidine is not expected to be of clinical importance. The starting dose range is 10 mg/kg/day to 15 mg/kg/day, given in three divided doses, and the recommended maintenance dose reached by upward titration over a period of approximately 3 days. Gabapentin acts on the central nervous system and may cause drowsiness, dizziness or other related symptoms.
