Gabapentin by Sorres Pharma Inc.
Gabapentin by Sorres Pharma Inc. Uses, Dosage, Side Effects, Food Interaction and all others data.
Gabapentin by Sorres Pharma Inc. is an anti-convulsant. It is a structural analog of gamma-amino-butyric-acid (GABA). All pharmacological actions following administration of Gabapentin by Sorres Pharma Inc. are due to the activity of parent compound. Gabapentin by Sorres Pharma Inc. binds with the alpha-2-delta subunit of voltage gated L-type Calcium channel, and inhibits branched chain amino acid transferase & probably inhibits neurotransmitter release of excitatory amino acid.
Gabapentin by Sorres Pharma Inc. is an anti-convulsant medication that inhibits the release of excitatory neurotransmitters, allowing for its use against pathologic neurotransmission such as that seen in neuropathic pain and seizure disorders. It has a wide therapeutic index, with doses in excess of 8000 mg/kg failing to cause a fatal reaction in rats.
Gabapentin by Sorres Pharma Inc. is ineffective in absence seizures and should be used in caution in patients with mixed seizure disorders involving absence seizures. Gabapentin by Sorres Pharma Inc. has been associated with drug reaction with eosinophilia and systemic symptoms (DRESS), otherwise known as multi-organ hypersensitivity. This reaction can prove fatal and early symptoms such as fever, lymphadenopathy, and rash should be promptly investigated.

How Gabapentin by Sorres Pharma Inc. works
The precise mechanism through which gabapentin exerts its therapeutic effects is unclear. The primary mode of action appears to be at the auxillary α2δ-1 subunit of voltage-gated calcium channels (though a low affinity for the α2δ-2 subunit has also been reported). The major function of these subunits is to facilitate the movement of pore-forming α1 subunits of calcium channels from the endoplasmic reticulum to the cell membrane of pre-synaptic neurons. There is evidence that chronic pain states can cause an increase in the expression of α2δ subunits and that these changes correlate with hyperalgesia. Gabapentin by Sorres Pharma Inc. appears to inhibit the action of α2δ-1 subunits, thus decreasing the density of pre-synaptic voltage-gated calcium channels and subsequent release of excitatory neurotransmitters. It is likely that this inhibition is also responsible for the anti-epileptic action of gabapentin.
There is some evidence that gabapentin also acts on adenosine receptors and voltage-gated potassium channels, though the clinical relevance of its action at these sites is unclear.
Dosage
Gabapentin by Sorres Pharma Inc. dosage
Neuropathic pain: 300 mg on day-1, then 300 mg twice on day-2, then 300 mg thrice on day-3, then increase the dose according to response in steps of 300 mg daily to maximum 1800 mg daily in three divided doses.
Partial seizure/epilepsy: 300 mg on day-1, then 300 mg twice on day-2, then 300 mg thrice on day-3, then increase the dose according to response in steps of 300 mg daily to maximum 2400 mg daily in three divided doses.
In case of children:
- For 3-12 years: 10 to 15 mg/kg, Incase of titration 25-35 mg/kg daily in 3 divided doses.
- Maintenance dose is 900 mg daily (body weight 26-36 Kg) or 1.2 gm daily (body weight 37-50 Kg).
Gabapentin by Sorres Pharma Inc. can be taken orally with or without food.
Side Effects
Generally Gabapentin by Sorres Pharma Inc. is well tolerated but a few side effects like fatigue, dizziness , ataxia, weight gain, peripheral edema, dry mouth and somnolence, may occur. Rarely it may cause fulminate hepatic failure, or aplasticanemia.
Toxicity
The oral TDLo of gabapentin in humans is 2.86 mg/kg and the LD50 in rats has been found to be >8000 mg/kg. Symptoms of overdose are consistent with the drug's adverse effect profile and involve CNS depression (e.g. dizziness, drowsiness, slurred speech, lethargy, loss of consciousness) and gastrointestinal symptoms such as diarrhea. Management of overdose should involve symptomatic and supportive treatment. Gabapentin by Sorres Pharma Inc. can be removed by hemodialysis - this may be of benefit in some patients, such as those with impaired renal function.
Multi-drug overdoses involving gabapentin, particularly in combination with other CNS depressants such as opioids, can result in coma and death - this possibility should be considered when managing overdosage.
Precaution
Patients should be instructed to take Gabapentin by Sorres Pharma Inc. only as prescribed. While using Gabapentin by Sorres Pharma Inc. patients should be instructed either not to drive a car or to operate other complex machinery until they have gained sufficient experiences about Gabapentin by Sorres Pharma Inc. whether or not it affects their mental and/or motor performance adversely.
Interaction
Antacids may reduce the bioavailability of Gabapentin by Sorres Pharma Inc. by up to 20%. Cimetidine may alter its reanal excretion. Gabapentin by Sorres Pharma Inc. does not interact with other anti-epileptic drug or with oral contraceptive preparations.
Food Interaction
- Avoid alcohol. Gabapentin by Sorres Pharma Inc. possesses CNS depressant activity that may be potentiated by co-administration with alcohol.
- Take with or without food. Co-administration with food slightly alters pharmacokinetics, but not to a clinically significant extent.
[Moderate] GENERALLY AVOID: Alcohol may potentiate some of the pharmacologic effects of CNS-active agents.
Use in combination may result in additive central nervous system depression and
MANAGEMENT: Patients receiving CNS-active agents should be warned of this interaction and advised to avoid or limit consumption of alcohol.
Ambulatory patients should be counseled to avoid hazardous activities requiring complete mental alertness and motor coordination until they know how these agents affect them, and to notify their physician if they experience excessive or prolonged CNS effects that interfere with their normal activities.
Gabapentin by Sorres Pharma Inc. Drug Interaction

Volume of Distribution
The apparent volume of distribution of gabapentin after IV administration is 58±6 L. The drug is found in the CSF in concentrations approximately 9-20% of the corresponding plasma concentrations and is secreted into breast milk in concentrations similar to that seen in plasma.
Elimination Route
Absorption of gabapentin is thought to occur solely via facilitated transport by the LAT1 transporter within the intestines. As this process is saturable, the oral bioavailability of gabapentin is inversely proportional to the administered dose - the oral bioavailability of a 900mg/day regimen is approximately 60%, whereas a 4800mg/day regimen results in only 27% bioavailability. The Tmax of gabapentin has been estimated to be 2-3 hours. Food has no appreciable effect on gabapentin absorption.
Clearance
Both the plasma clearance and renal clearance of gabapentin are directly proportional to the patient's creatinine clearance due to its primarily renal elimination.
Elimination Route
Gabapentin by Sorres Pharma Inc. is eliminated solely in the urine as unchanged drug. Cimetidine, an inhibitor of renal tubular secretion, reduces clearance by approximately 12%, suggesting that some degree of tubular secretion is involved in the renal elimination of gabapentin.
Pregnancy & Breastfeeding use
Pregnancy: Gabapentin by Sorres Pharma Inc. is a pregnancy category C drug; it should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
Lactation: Gabapentin by Sorres Pharma Inc. may be secreted through the breast milk like many other drugs , so it should be used in women who are nursing, only if the benefits clearly outweigh the risks.
Contraindication
Gabapentin by Sorres Pharma Inc. is contraindicated in patients who have known hypersensitivity to the drug.
