Pill with imprint IP 101 IP 101 is White, Capsule/Oblong and has been identified as Gabapentin 100 mg. It is supplied by Amneal Pharmaceuticals.
Gabapentin is used in the treatment of Back Pain; Postherpetic Neuralgia; Epilepsy; Chronic Pain; Seizures and belongs to the drug class gamma-aminobutyric acid analogs. Risk cannot be ruled out during pregnancy. Gabapentin 100 mg is not a controlled substance under the Controlled Substances Act (CSA).
The efficacy of Gabapentin in the treatment of neuropathic pain has been demonstrated in several placebo-controlled studies. In a study involving 502 patients with neuropathic pain treated with Gabapentin at a dose of 300 to 1800 mg/day, efficacy was assessed by the percentage of patients who had a 50% or more reduction in pain.
Gabapentin has been shown to be effective in 69% of patients receiving 900 or 1800 mg per day, and in 57% of patients taking 300-600 mg of Gabapentin. In approximately 80% of patients responding to therapy, the effect persisted after discontinuation of the drug.

Gabapentin is a medication that is primarily used to treat epilepsy and neuropathic pain.
Gabapentin is used to help control partial seizures (convulsions) in the treatment of epilepsy. This medicine cannot cure epilepsy and will only work to control seizures for as long as you continue to take it.
Gabapentin is also used to manage a condition called postherpetic neuralgia, which is pain that occurs after shingles.
Gabapentin works in the brain to prevent seizures and relieve pain for certain conditions in the nervous system. It is not used for routine pain caused by minor injuries or arthritis. Gabapentin is an anticonvulsant.
This medicine is available only with your doctor’s prescription.
This product is available in the following dosage forms:
- Capsule
- Tablet
- Tablet, Extended Release, 24 HR
- Solution
- Suspension
Its exact mechanism of action is not fully understood, but it is known to interact with certain components of the nervous system. Here is a detailed explanation of the proposed mechanisms by which gabapentin exerts its therapeutic effects:
Mechanism of Action
- Binding to the α2δ Subunit of Voltage-Gated Calcium Channels:
- Gabapentin binds with high affinity to the α2δ subunit of voltage-gated calcium channels in the central nervous system.
- This binding inhibits the influx of calcium ions into neurons, which in turn reduces the release of excitatory neurotransmitters such as glutamate, norepinephrine, and substance P.
- By decreasing the release of these neurotransmitters, gabapentin helps to stabilize neuronal activity and reduce the hyperexcitability that contributes to seizures and neuropathic pain.
- Reduction of Excitatory Neurotransmission:
- The inhibition of calcium influx and subsequent reduction in neurotransmitter release results in decreased excitatory synaptic transmission.
- This reduction in excitatory signaling is believed to contribute to the anticonvulsant and analgesic effects of gabapentin.
- Modulation of GABAergic Neurotransmission:
- Although gabapentin is structurally similar to the neurotransmitter gamma-aminobutyric acid (GABA), it does not directly bind to GABA receptors or influence GABA synthesis or uptake.
- However, gabapentin may enhance the synthesis of GABA and increase its release in certain brain regions, which could contribute to its overall calming effect on neuronal activity.
- Inhibition of Central Sensitization:
- In conditions like neuropathic pain, there is often a phenomenon known as central sensitization, where the nervous system becomes sensitized to pain stimuli.
- By inhibiting calcium influx and reducing excitatory neurotransmitter release, gabapentin helps to diminish central sensitization and alleviate chronic pain symptoms.
Therapeutic Effects
- Anticonvulsant:
- Gabapentin’s ability to decrease neuronal excitability and stabilize electrical activity in the brain makes it effective in controlling seizures, particularly partial seizures.
- Analgesic:
- The reduction in neurotransmitter release and inhibition of central sensitization make gabapentin effective in treating various forms of neuropathic pain, such as diabetic neuropathy and postherpetic neuralgia.
- Other Uses:
- Gabapentin is also used off-label for other conditions like restless legs syndrome (RLS) and certain anxiety disorders, where its modulatory effects on the nervous system can provide symptomatic relief.
