Gabapentin: study card

Gabapentin — Gabapentinoid anticonvulsant. Study the mechanism, listed uses and warnings from the US label on one sourced card.

Generic name
Gabapentin
Class
Gabapentinoid anticonvulsant
Mechanism
The exact analgesic and antiepileptic mechanisms are unknown. Gabapentin is structurally related to GABA but does not affect its binding, uptake or degradation. It binds the alpha-2-delta calcium-channel subunit in vitro; the relevance to therapeutic effects is unknown.
Used for
Postherpetic neuralgia in adults; Adjunctive treatment of partial-onset seizures in adults and children aged 3 or older
Common side effects
Dizziness; Somnolence; Peripheral edema; Ataxia; Fatigue
Warnings
DRESS (multiorgan hypersensitivity); Respiratory depression with CNS depressants; Suicidal behavior and ideation
Interactions
Opioids; Antacids (aluminum/magnesium hydroxide)

Brand questions use only name pairings verified against the linked product source. Unverified pairings are withheld from these questions; the other study content remains available.

Compare with related cards

Pregabalin

Same body system: Neurology

Mechanism: Binds with high affinity to the alpha-2-delta subunit of voltage-gated calcium channels in CNS tissue; exact mechanism not fully known.

On both cards: Used for — Postherpetic neuralgia in adults · Common side effects — Dizziness; Somnolence · Warnings — Respiratory depression with CNS depressants

Only on the Pregabalin card: Used for — Diabetic peripheral-neuropathy pain in adults; Adjunctive treatment of partial-onset seizures from age 1 month; Fibromyalgia in adults; Spinal-cord-injury neuropathic pain in adults · Common side effects — Dry mouth; Edema; Blurred vision · Warnings — Angioedema; Suicidal thoughts or behavior

Levetiracetam

Same body system: Neurology

Mechanism: The precise antiepileptic mechanism is unknown. Experimental data identify a binding site as synaptic vesicle protein SV2A, thought to regulate vesicle exocytosis; interaction with SV2A may contribute to the antiepileptic effect.

On both cards: Common side effects — Dizziness; Somnolence · Warnings — Suicidal behavior and ideation

Only on the Levetiracetam card: Used for — Partial-onset seizures from age 1 month; Adjunctive treatment of myoclonic seizures in juvenile myoclonic epilepsy from age 12; Adjunctive treatment of primary generalized tonic-clonic seizures in idiopathic generalized epilepsy from age 6 · Common side effects — Asthenia; Infection; Irritability (children) · Warnings — Behavioral abnormalities / psychotic symptoms; Withdrawal seizures if stopped abruptly

Oxcarbazepine

Same body system: Neurology

Mechanism: Activity is mainly mediated by MHD. The precise anti-seizure mechanism is unknown; in-vitro studies indicate voltage-sensitive sodium-channel blockade that stabilizes hyperexcited membranes.

On both cards: Common side effects — Dizziness; Somnolence; Fatigue

Only on the Oxcarbazepine card: Used for — Partial-onset seizures: monotherapy or adjunctive treatment in adults; Partial-onset seizures: monotherapy in children aged 4 years and older; Partial-onset seizures: adjunctive treatment in children aged 2 years and older · Common side effects — Diplopia; Nausea · Warnings — Hyponatremia; Serious dermatological reactions; Cross-hypersensitivity to carbamazepine · Interactions — Phenytoin; Strong CYP inducers (e.g., carbamazepine); Hormonal contraceptives

An item counts as shared only when both cards use the same wording. If a card does not list an item, that is not a statement that the effect never occurs.
