| description | drug |
|---|---|
| agonist at opiod receptors to modulate synaptic transmission | opiod analgesics |
| block Na+ channel; inhibit glutamate release | phenytoin |
| increase DURATION of Cl- channel opening --> increase GABA(A) action | barbituates |
| increase FREQUENCY of Cl- channel openeing --> increase GABA(A) action | BZD |
| used for pain, cough suppression, diarrhea, acute pulmonary edema | opiods |
| induction of anesthesia | barbituates (thiopental) |
| for detox, especially EtOH withdrawl (DT), night terrors, sleepwalking | BZD |
| neuro drugs that incrase P450 | barbituates, phenytoin, carbamazepine |
| SE: respiratory depression, pinpoint pupils, CNS depression | opioids |
| additive CNS depression effects with EtOH | barbituates, BZD |
| SE: nystagmus, diplopia, SLE-syndrome, increases P450 | phenytoin |
| BZD OD treatment | flumazenil --> competitive antag at GABA receptor |
| opiod OD treatment | naloxone/naltrexone --> opioid receptor antag |
| anti-seizure drugs also used for bipolar treatment | carbamazepine, lamotrigine, valproic acid |
| 1st line for tonic-clonic seizures | phenytoin, carbamazpine, valproic acid |
| 1st line for absence seizures | ethosuximide |
| 1st line for status epilepticus seizures | BZD (diazepam, lorazepam) |
| 1st line for status epilepticus prophylaxis | phenytoin |
| 1st line for trigeminal neuralgia | carbamazepine |

| 1st line for epilepsy in pregnancy and children | phenobarbital |
| also used for myoclonic seizures | valproic acid |
| also used for eclampsia seizures | BZD |
| 1st line to prevent eclampsia seizures | MgSO4 |
| increase Na+ channel inactivation | phenytoin, carbamazepine, valproic acid |
| blocks voltage gated Na+ channels | lamotrigine |
| increase GABA release | gabapentin |
| increase GABA(A) action | phenobarbital, BZD |
| increase [GABA] | valproic acid |

| CANNOT cross BBB | dopamine |
| able to cross BBB | L-dopa |
| given with L-dopa to increase bioavailability of L-dopa in brean and decrease peripheral effects | carbidopa |
| inhibit MAO-B ---> prevents DA breakdown in brain | selegiline |
