Description
An Orally disintegrating tablet conta' * g Gabapentin or pharmaceutically acceptable salts thereof and the process of preparing the same
Field of the Invention
The present invention relates to a pharmaceutical composition of Gabapentin. The present invention relates to an orally disintegrating tablet of Gabapentin or pharmaceutically acceptable salts thereof for oral administration. The present invention also relates to the process of the preparation of the same
Background of the Invention
Gabapentin was first disclosed in the US 4024175. Gabapentin is a structural analogue of the inhibitory neurotransmitter gamma-aminobutyric acid (GABA).
The primary mode of action appears to be at the auxiliary a25-1 subunit of voltage- gated calcium channels The major function of these subunits is to facilitate the movement of pore-forming a28-1 subunits of calcium channels from the endoplasmic reticulum to the cell membrane of pre-synaptic neurons. Gabapentin appears to inhibit the action of a28-1 subunits, thus decreasing the density of pre-synaptic voltage-gated calcium channels and the subsequent release of excitatory neurotransmitters.
Gabapentin is indicated for the treatment of postherpetic neuralgia and various types of peripheral neuropathic pain, such as painful diabetic neuropathy in adults and partial-onset seizures in paediatrics The 1UPAC name of gabapentin is 2-[]-(amino methyl) cyclohexyllacetic acid. The plasma half-life of gabapentin in patients with normal renal function is 5-7 hours Gabapentin is a high-water solubility and low permeability drug which makes it belong to BCS Class-Ill in the Biopharmaceutical classification system.
Gabapentin is marketed, particularly as an oral tablet, capsule, or solution. The commercially marketed products of Gabapentin in tablet form are available in five dosage strengths: 100, 300, 400, 600, and 800 mg for oral administration. Orally disintegrating tablets provides a good mouth feel property that improves patient compliance, particularly for paediatric patients. Moreover, Gabapentin is a freely water-soluble drug, making it a suitable drug for orally disintegrating tablet.
The marketed tablet of gabapentin is available in large size which is difficult to swallow for elderly, paediatrics resulting in patient noncompliance Therefore, Gabapentin is a good candidate for formulating the orally dispersible tablet as it is easy to swallow and would provide patient compliance for paediatrics, geriatric and psychiatric patients disabled bedridden patients, and for traveling and busy people, who do not have ready access to water or difficulty in swallowing.
The orally disintegrating tablet of the present invention is a pharmaceutical formulation that rapidly disintegrates in the mouth which helps in easy administration of tablet and provide accurate dosing as compared to liquid formulations.
EP 1784174A1 discloses a stable pharmaceutical composition comprising gabapentin as the active ingredient, tribasic calcium phosphate as a sliding agent, hydrogenated castor oil as a lubricant, sorbitol and alginic acid in mixture as diluents.

The final mixture is filtrated and filled into bottles.
EP1558218A1 discloses the conventional tablet comprising gabapentin and one or more excipients. The manufacturing process of this invention involves a wet granulation method as per following steps: a first portion of a binder is added to dried mixture of gabapentin and one or more excipients as combination or in separate way. To the dried granules, a second portion of binder in solution or dispersion form is added, followed by drying granules and then compressing dried granules into tablets.

The manufacturing process of this invention involves forming granules by mixing gabapentin with rate-controlling polymer and inactive ingredients, a water or binder solution is added to pre-mixed granules followed by drying the wet granules and compressed into tablets which provides gabapentin release for up to 12 hours.
1JS20090176882A1 discloses the gastric retentive oral dosage form of gabapentin for once or twice daily dose administration for improving patient compliance The process of this invention involves dispersing gabapentin in hydrophilic polymer that upon ingestion into gastric fluid swells to a size sufficient to achieve retention of the dosage form in the stomach in a fed mode for a period of at least about five hours
