What is G Gab?
G Gab (G Gab) is an anti-epileptic drug, also called an anticonvulsant. G Gab works by slowing down nerve impulses in the brain and affects chemicals that send pain signals across the nervous system.
G Gab is a prescription medicine used to treat pain caused by damaged nerves in people with diabetes (diabetic neuropathy). G Gab is also used to treat pain caused by damaged nerves (neuropathic pain) that follows healing of shingles (herpes zoster). This condition is called post-herpetic neuralgia.
.
It is not known if G Gab is effective when used for the treatment of fibromyalgia, or when taken with other seizure medicines for adults with partial onset seizures.
G Gab is supplied as extended-release tablets in the following strengths: 82.5 mg, 165 mg, and 330 mg.

Based on the American Association of Clinical Endocrinologists (AACE) and American College of Endocrinology (ACE) position statement on menopause, the Endocrine Society guideline on the treatment of symptoms of menopause, and the North American Menopause Society (NAMS) position statement on nonhormonal management of menopause-associated vasomotor symptoms, G Gab is an effective and recommended alternative for the management of vasomotor symptoms associated with menopause in patients with contraindications to hormonal therapy or who prefer not to use hormonal therapy.
G Gab description
Each capsule contains the following inactive ingredients: Mannitol, maize starch and talc.
G Gab is described chemically as (S)-3-(aminomethyl)-5-methylhexanoic acid. The molecular formula is C8H17NO2 and the molecular weight is 159.23.
G Gab is a white to off-white, crystalline solid with a pKa1 of 4.2 and a pKa2 of 10.6. It is freely soluble in water and both basic and acidic aqueous solutions. The log of the partition coefficient (n-octanol/0.05 M phosphate buffer) at pH 7.4 is -1.35.
G Gab dosage
The dose range is 150 to 600 mg per day given in either two or three divided doses.
Epilepsy: G Gab treatment can be started with a dose of 150 mg per day given as two or three divided doses. Based on individual patient response and tolerability, the dose may be increased to 300 mg per day after 1 week. The maximum dose of 600 mg per day may be achieved after an additional week.
Generalised Anxiety Disorder: The dose range is 150 to 600 mg per day given as two or three divided doses. The need for treatment should be reassessed regularly.
G Gab treatment can be started with a dose of 150 mg per day. Based on individual patient response and tolerability, the dose may be increased to 300 mg per day after 1 week. Following an additional week, the dose may be increased to 450 mg per day. The maximum dose of 600 mg per day may be achieved after an additional week.
Discontinuation of G Gab: In accordance with current clinical practice, if G Gab has to be discontinued, it is recommended this should be done gradually over a minimum of 1 week independent of the indication.
Patients with Renal Impairment: G Gab is eliminated from the systemic circulation primarily by renal excretion as unchanged drug. As G Gab clearance is directly proportional to creatinine clearance, dose reduction in patients with compromised renal function must be individualised according to creatinine clearance (CrCl), as indicated in Table 1 determined using the following formula.
G Gab is removed effectively from plasma by haemodialysis (50% of drug in 4 hours). For patients receiving haemodialysis, the G Gab daily dose should be adjusted based on renal function. In addition to the daily dose, a supplementary dose should be given immediately following every 4-hour haemodialysis treatment.
Patients with Hepatic Impairment: No dose adjustment is required for patients with hepatic impairment.
Children: The safety and efficacy of G Gab Sandoz in children below the age of 12 years and in adolescents (12-17 years of age) have not been established. No data are available.
Elderly (over 65 years of age): Elderly patients may require a dose reduction of G Gab due to a decreased renal function.
Administration: G Gab Sandoz may be taken with or without food.
G Gab Sandoz is for oral use only.
G Gab interactions

What other drugs will affect G Gab?
Since G Gab is predominantly excreted unchanged in the urine, undergoes negligible metabolism in humans (<2% of a dose recovered in urine as metabolites), does not inhibit drug metabolism in vitro and is not bound to plasma proteins, it is unlikely to produce or be subject to pharmacokinetic interactions.
Accordingly, in in vivo studies no clinically relevant pharmacokinetic interactions were observed between G Gab and phenytoin, carbamazepine, valproic acid, lamotrigine, gabapentin, lorazepam, oxycodone or ethanol. Population pharmacokinetic analysis indicated that the oral antidiabetics, diuretics, insulin, phenobarbital, tiagabine and topiramate had no clinically significant effect on G Gab clearance.
Co-administration of G Gab with the oral contraceptives norethisterone and/or ethinyl oestradiol does not influence the steady-state pharmacokinetics of either substance. G Gab may potentiate the effects of ethanol and lorazepam. In controlled clinical trials, multiple oral doses of G Gab co-administered with oxycodone, lorazepam or ethanol did not result in clinically important effects on respiration. In the post-marketing experience, there are reports of respiratory failure and coma in patients taking G Gab and other CNS depressant medications. G Gab appears to be additive in the impairment of cognitive and gross motor function caused by oxycodone.
No specific pharmacodynamic interaction studies were conducted in elderly volunteers.

What are the possible side effects of G Gab?
The G Gab clinical program involved over 8900 patients who were exposed to G Gab, of whom over 5600 were in double-blind placebo-controlled trials. The most commonly reported adverse reactions were dizziness and somnolence. Adverse reactions were usually mild to moderate in intensity. In all controlled studies, the discontinuation rate due to adverse reactions was 12% for patients receiving G Gab and 5% for patients receiving placebo. The most common adverse reactions resulting in discontinuation from G Gab treatment groups were dizziness and somnolence.
In Table 2 all adverse reactions, which occurred at an incidence greater than placebo and in more than one patient, are listed by class and frequency (very common (≥1/10), common (≥1/100, <1/10), uncommon (≥1/1000, <1/100), rare (≥1/10,000 to <1/1,000); very rare (<1/10,000), not known (cannot be estimated from the available data). Within each frequency grouping, undesirable effects are presented in order of decreasing seriousness.
The adverse reactions listed may also be associated with the underlying disease and/or concomitant medicinal products.
In the treatment of central neuropathic pain due to spinal cord injury the incidence of adverse reactions in general, CNS adverse reactions and especially somnolence was increased.
Additional reactions reported from post-marketing experience are included in italics in Table 2.
After discontinuation of short-term and long-term treatment with G Gab withdrawal symptoms have been observed in some patients. The following reactions have been mentioned: insomnia, headache, nausea, anxiety, diarrhoea, flu syndrome, convulsions, nervousness, depression, pain, hyperhidrosis and dizziness, suggestive of physical dependence. The patient should be informed about this at the start of the treatment.
Concerning discontinuation of long-term treatment of G Gab, data suggest that the incidence and severity of withdrawal symptoms may be dose-related.
