Gabapentin (Neurontin) is a pharmaceutical drug, specifically a GABA analog. It was originally developed to treat epilepsy, and currently is also used to relieve neuropathic pain. There are, however, concerns regarding the quality of the trials conducted for a number of conditions

Gabapentin capsules, tablets, and oral solution are used to help control certain types of seizures in people who have epilepsy. Gabapentin capsules, tablets, and oral solution are also used to relieve the pain of postherpetic neuralgia (PHN; the burning, stabbing pain or aches that may last for months or years after an attack of shingles). Gabapentin extended-release tablets (Horizant) are used to treat restless legs syndrome (RLS; a condition that causes discomfort in the legs and a strong urge to move the legs, especially at night and when sitting or lying down).

Gabapentin is in a class of medications called anticonvulsants. Gabapentin treats seizures by decreasing abnormal excitement in the brain. Gabapentin relieves the pain of PHN by changing the way the body senses pain. It is not known exactly how gabapentin works to treat restless legs syndrome.

But you must complete the health questionnaires very honestly and carefully. The doctors must know your health condition to prescribe you the prescriptions. They may call you to discuss your health condition and medical condition and they will not prescribe you the medicines if they cannot catch you.

Gabapentin Warnings and Precautions

Neurontin has been tested in children and adolescents from 3 to 18 years old, and its effects have been found to be the same as those in adults, when dosage is appropriately adjusted.  Neurontin may impair the ability to drive or operate heavy machinery.

Neurontin should not be discontinued suddenly – sudden withdrawal may cause seizures to return or occur more frequently. Dosage should be gradually tapered over at least 7 days when Neurontin is discontinued. For Pregnant or Nursing Mothers: Neurontin has not been studied in pregnant women, but other antiepileptic drugs have been known to cause birth defects. Studies in animals indicate that very high doses of Neurontin can cause bone and kidney problems. It is not known whether Neurontin passes into breast milk, and nursing mothers should be cautious about using Neurontin.

You yourself must know the drug you are going to take. You can not overdose the drugs especially fioricet. Fioricet contains tylenol, tylenol can damage your liver, heart, and kidneys seriously if you overdose it. You also must know the side effects of Fioricet and Gabapentin. You also must know the Drug Interactions of Fioricet, and Gabapentin. You should not order fioricet, order Gabapentin online if you are taking drugs in those drug interaction lists.

By some websites and health professional reasearch, Gabapentin is even a better Analgesic than Tramadol. That reasearch is from a health professional group from the University of Victoria. Because tramadol is a controlled medicine now, we do suggest you order gabapentin online. We provide the cheapest authentic COD gabapentin and cod fioricet online with USPS priority mail services.

Normal Dosage Of Gabapentin

USAGE FOR EPILEPSY: The usual starting dose is 300mg for adults and children over 12 years of age. This dose is taken on the evening of the first day. Your doctor may then increase the dose on the second day to 300mg in the morning, and 300mg in the evening. On the third day you may be increased to 300mg three times per day. The maximum dosage is 3600mg per day. Gabapentin is not recommended for children under 12 years.

USAGE FOR DIABETIC NERVE PAIN: The dosage follows the rules for epilepsy, and may be continued for up to 5 months. If you suffer from any kidney problems, the doctor may issue a lower dosage.

USAGE AS A NERVE BLOCK:  Gabapentin is not marketed for use as a nerve block, but is commonly used as such following successful applications. The dosage follows the same rules as for epilepsy patients, with a maximum dosage of 3600mg. For chronic pain conditions, Gabapentin may need

Gabapentin Mechanism of action

The mechanism of the anticonvulsant action of gabapentin has not been fully described. Several possible mechanisms for pain improvement have been discussed. Though similar in structure to the endogenous neurotransmitter GABA, gabapentin has not been shown to bind to GABA receptors at concentrations at or below 1 mM.  Gabapentin modulates the action of glutamate decarboxylase (GAD) and branched chain aminotransferase (BCAT), two enzymes involved in GABA biosynthesis. In human and rat studies, gabapentin was found to increase GABA biosynthesis, and to increase non-synaptic GABA neurotransmission in vitro.

Gabapentin prevents seizures in a wide variety of models in animals, including generalized tonic-clonic and partial seizures. Gabapentin has no activity at GABAA or GABAB receptors of GABA uptake carriers of brain. Gabapentin interacts with a high-affinity binding site in brain membranes, which has recently been identified as an auxiliary subunit of voltage-sensitive Ca2+ channels.

Gabapentin has been shown to bind to the α2δ-1 subunit of voltage gated calcium ion channels, which contributes to its pain attenuation effects in diabetic neuropathy and post-herpetic neuralgia. Other neurophysiological findings indicate that gabapentin also interacts with NMDA receptors, protein kinase C, and inflammatory cytokines.

Gabapentin prevents pain responses in several animal models of hyperalgesia and prevents neuronal death in vitro and in vivo with models of the neurodegenerative disease amyotrophic lateral sclerosis (ALS). Gabapentin is also active in models that detect anxiolytic activity.

Although gabapentin may have several different pharmacological actions, it appears that modulation of GABA synthesis and glutamate synthesis may be important.

Gabapentin interacts with cortical neurons at auxillary subunits of voltage-sensitive calcium channels. Gabapentin increases the synaptic concentration of GABA, enhances GABA responses at non-synaptic sites in neuronal tissues, and reduces the release of mono-amine neurotransmitters.

One of the mechanisms implicated in this effect of gabapentin is the reduction of the axon excitability measured as an amplitude change of the presynaptic fibre volley (FV) in the CA1 area of the hippocampus. This is mediated through its binding to presynaptic NMDA receptors.

Other studies have shown that the antihyperalgesic and antiallodynic effects of gabapentin are mediated by the descending noradrenergic system, resulting in the activation of spinal alpha2-adrenergic receptors. Gabapentin has also been shown to bind and activate the adenosine A1 receptor.

Gabapentin Interactions with Drugs and Other Substances

Drugs or substances that may interact with Neurontin include:

• Antacids (within 2 hours) – taking Neurontin with antacids may reduce Neurontin’s effects.
• Alcohol – frequent use of alcohol may seriously reduce the effectiveness of Neurontin.
• Tagamet (cimetidine) – may increase blood levels of Neurontin.
• Dilantin (phenytoin) – taking Neurontin with Dilantin may lead to phenytoin toxicity.
• Central nervous system (CNS) depressants, including cold medicines – these medications may add to the sedative effects of Neurontin.

Gabapentin For Migraine Prevention

International and domestic studies that have evaluated Neurontin for migraine prevention suggest that it is effective. In a study of 63 patients with migraine (with or without aura), gabapentin significantly reduced migraine frequency and intensity among 30 patients who received it. In this study, adverse events were mild to moderate in severity.

Similarly, in a large study, 143 people with migraine received daily doses of Neurontin or placebo for 12 weeks. At the end of 12 weeks, the migraine rate had declined from 4.2 migraines before treatment to 2.7 migraines after treatment in those who received this drug. This decrease was significantly greater than the decrease from 4.1 migraines to 3.5 migraines among those who received placebo. Of the 56 gabapentin recipients, 46% had at least a 50% reduction in the four-week migraine rate. Drug-related adverse events (sleepiness and dizziness) led to drug withdrawal in 13% of patients in the gabapentin group compared with 7% in the placebo group. The researchers concluded that this medication is an effective and well-tolerated preventive for migraine.

However, the American Academy of Neurology (AAN), the organization that provides guidance for the use of drugs to prevent migraines, has stated that there is not enough evidence at this time to support the use of gabapentin for migraine prevention. Healthcare professionals can choose to prescribe gabapentin when other prevention therapies have not worked, however.

Some people can prevent migraines by avoiding triggers. Others have prevented migraines successfully through relaxation techniques, acupuncture, or exercise. However, these therapies alone don’t work for everyone. Some people also need treatment with medication to reduce the number of migraines they have. The drugs used to prevent migraines are different from drugs that to treat migraines once a migraine starts. Drugs that prevent migraines, such as gabapentin, must be taken daily.

COMMON BRAND NAME(S): Neurontin

USES: Gabapentin is used with other medications to prevent and control seizures. It is also used to relieve nerve pain following shingles (a painful rash due to herpes zoster infection) in adults. Gabapentin is known as an anticonvulsant or antiepileptic drug.

OTHER USES: This section contains uses of this drug that are not listed in the approved professional labeling for the drug but that may be prescribed by your health care professional. Use this drug for a condition that is listed in this section only if it has been so prescribed by your health care professional. Gabapentin may also be used to treat other nerve pain conditions (such as diabetic neuropathy, peripheral neuropathy, trigeminal neuralgia) and restless legs syndrome.

HOW TO USE: Read the Medication Guide and, if available, the Patient Information Leaflet provided by your pharmacist before you start taking gabapentin and each time you get a refill. If you have any questions, ask your doctor or pharmacist. Take this medication by mouth with or without food as directed by your doctor. Dosage is based on your medical condition and response to treatment. For children, the dosage is also based on weight. If you are taking the tablets and your doctor directs you to split the tablet in half, take the other half-tablet at your next scheduled dose. Discard half tablets if not used within several days of splitting them. If you are taking the capsules, swallow them whole with plenty of water. It is very important to follow your doctor’s dosing instructions exactly. During the first few days of treatment, your doctor may gradually increase your dose so your body can adjust to the medication. To minimize side effects, take the very first dose at bedtime. Take this medication regularly to get the most benefit from it. This drug works best when the amount of medicine in your body is kept at a constant level. Therefore, take gabapentin at evenly spaced intervals at the same time(s) each day. If you are taking this medication 3 times a day to control seizures, do not let more than 12 hours pass between doses because your seizures may increase. Do not take this medication more often or increase your dose without consulting your doctor. Your condition will not improve any faster and the risk of serious side effects may increase. Do not stop taking this medication without consulting your doctor. Some conditions may become worse when the drug is suddenly stopped. Your dose may need to be gradually decreased. Antacids containing aluminum or magnesium may interfere with the absorption of this medication. Therefore, if you are also taking an antacid, it is best to take gabapentin at least 2 hours after taking the antacid. Different forms of gabapentin (such as immediate-release, sustained-release, enacarbil sustained-release) are absorbed in the body differently. Do not switch from one form to the other without consulting your doctor. Tell your doctor if your condition does not improve or if it worsens.
