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.
Label date: 20260904 · For learning, not clinical decisions. US label and brand information; always consult the current source.
Source snapshot checked: 2026-10-21. The source document and selected fields were compared. The complete card has not had an independent clinical review.
Mechanism: Non-ergot dopamine agonist with in-vitro activity at D2-family receptors and greater affinity for D3 than D2 or D4. The precise mechanisms in Parkinson disease and restless legs syndrome are unknown.
On both cards: Common side effects — Nausea; Somnolence; Dizziness; Hallucinations · Warnings — Falling asleep during daily activities; Impulse control / compulsive behaviors
Only on the Pramipexole card: Used for — Parkinson disease in adults; Moderate-to-severe primary restless legs syndrome in adults · Common side effects — Insomnia · Warnings — Orthostatic hypotension · Interactions — Dopamine antagonists (neuroleptics, metoclopramide)
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 — Nausea; Somnolence; Dizziness
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; Fatigue · Warnings — Hyponatremia; Serious dermatological reactions; Cross-hypersensitivity to carbamazepine · Interactions — Phenytoin; Strong CYP inducers (e.g., carbamazepine); Hormonal contraceptives
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.
On both cards: Common side effects — Somnolence; Dizziness
Only on the Gabapentin card: Used for — Postherpetic neuralgia in adults; Adjunctive treatment of partial-onset seizures in adults and children aged 3 or older · Common side effects — Peripheral edema; Ataxia; Fatigue · Warnings — DRESS (multiorgan hypersensitivity); Respiratory depression with CNS depressants; Suicidal behavior and ideation · Interactions — Opioids; Antacids (aluminum/magnesium hydroxide)
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.
