Gabapentin Chemical Properties,Uses,Production


Gabapentin is a second- generation antiepileptic drug (AED) known under the proprietary brand name of Neurontin® (Pfizer, New York, NY) in the UK and USA.

Generic formulation

MHRA/ CHM advice to minimize risk when switching patients with epilepsy between different manufacturers’ products (including generic products):


Epilepsy: monotherapy or adjunctive therapy of focal seizures with or without secondary generalization. Recommendations summarized from NICE (2012)

Dose titration

Monotherapy or adjunctive therapy
300 mg od for day 1300 mg bd for day 2300 mg td for day 3 (or 300 mg td for day 1), then increased by 300 mg every 2– 3 days, divided into three doses; usual maintenance 900– 3600 mg daily, divided into three doses (max. 4800 mg daily) If gabapentin has to be discontinued, it is recommended this should be done gradually over a minimum of 1 week, independent of the indication.



With AEDs

With other drugs
With alcohol/food
There are no known specific interactions between alcohol and gabapentin and there are no specific foods that must be excluded from diet when taking gabapentin.

Special populations

Renal impairment
Reduce maintenance dose according to degree of reduction in creatinine clearance.


Behavioural and cognitive effects in patients with epilepsy

Gabapentin has a relatively favourable behavioural profile, although paradoxical hyperactivity, irritability and aggression have been occasionally reported, especially in patients with severe intellectual disabilities. The cognitive profile of gabapentin is equally favourable, as this AED has been associated with only minor cognitive difficulties (mainly in the attention domain).

Psychiatric use

Although gabapentin has no approved indications in psychiatry, it has shown efficacy in the treatment of anxiety disorders, especially social phobia. Other offlabel uses include other anxiety disorders (panic disorder, post- traumatic stress disorder), alcohol dependence and withdrawal, behavioural and psychological symptoms of dementia, and aggression. Gabapentin has also been proposed to be useful in the maintenance treatment of bipolar disorder as adjunctive therapy.


Gabapentin was introduced in 1993 in the UK and early 1994 in the USA as an adjunctive therapy in the treatment of refractory partial seizures and secondarily generalized tonic-clonic seizures. Although being a lipophilic analog of the neurotransmitter GABA, gabapentin appears to exert its anticonvulsive function by a GABA receptor independent mechanism, possibly involving the L-system amino acid transporter protein. Gabapentin easily crosses the blood brain barrier and exhibits a favorable pharmacokinetic profile with high tolerability. It does not interfere with the metabolism of other concomitant administered antiepileptic drugs, thus having a low potential for drug interactions. Studies are currently underway for the use of gabapentin as mono-therapy for the treatment of various seizures.

Biological Functions

Gabapentin (Neurotonin) was initially designed to be a rigid analogue of GABA. When it was discovered to have antiepileptic properties, it was assumed that this activity was related to a GABAergic mechanism. However, subsequent studies have failed to show any GABAergic activity of gabapentin. Although it has not yet been possible to ascribe any definite mechanism to its antiepileptic activity, there is recent evidence that it may function as an agonist at GABAB receptors in the brain.
Gabapentin is recommended as adjunctive therapy in the treatment of partial seizures in adults.When used with other drugs, it appears to be an effective AED; it is usually not effective when employed alone for patients with severe seizures.
Gabapentin is generally well tolerated, with somnolence, dizziness, and ataxia the most commonly reported adverse effects. A low incidence of potentially serious side effects and no significant allergic reactions have been reported.

General Description

Gabapentin and its closely related analog pregabalin,(S)-3-isobutyl-GABA, are broad-spectrum anticonvulsantswith multiple mechanisms of action.24,51 Inaddition to modulating calcium influx and stimulateGABA biosynthesis as discussed earlier, they also competefor the biosynthesis of L-glutamic acid because oftheir structural similarity to L-leucine.51 Gabapentin andpregabalin have very little liability for causing metabolicbaseddrug–drug interactions, particularly when used incombination with other AEDs because they are not metabolizedin humans. More than 95% of the drug is excretedunchanged through the kidneys. However, there are somedifferences in their bioavailability. Unlike gabapentin,which exhibits 60% bioavailability when given in lowdoses because of intestinal uptake by a saturable smallneutral L-amino acid transporter, the absorption of pregabalinis almost complete (98%) and exhibits an ideal linear pharmacokinetic profile.24 This high bioavailability of pregabalincan be attributed to its closer structure similarity tothe essential amino acid, L-leucine.

Biological Activity

Anticonvulsant with several possible mechanisms of action. Increases GABA in the brain and binds to a novel site associated with voltage-sensitive Ca 2+ channels. Prevents neuronal death and is antinociceptive and anxiolytic.
