Antidepressants, Antipsychotics, & Anticonvulsants Flashcards
To recognize Certain Antidepressants, Antipsychotics, & Anticonvulsants and their indication of use
Amitriptyline HCl
Elavil
Indication(s): Depression
MOA: inhibits the membrane pump mechanism responsible for the re-uptake of norepinephrine & serotonin at the presynaptic nerve terminals.
Aripiprazole
Abilify
Indication(s): Schizophrenia, bipolar disorder
MOA: Exact MOA is unknown, but may be due to a combination of partial agonist activity at dopamine D2 & Serotonin 5-HT1A receptors & antagonist activity at 5-HT2A receptors. metabolized by CYP3A4 & CYP2D6 enzymes to dehydro-aripipazole following oral administration.
Bupropion XL
Wellbutrin, Zyban
Indication(s): Depression, Seasonal Affective Disorder
MOA: weak inhibitor of neuronal uptake of norepinephrine, serotonin & dopamine, and does not inhibit monoamine oxidase.
Citalopram Hydrobromide
Celexa
Indication: Depression
MOA: Blocks the neuronal uptake of serotonin. but not of norepinephrine or dopamine, into human platelets in the CNS. Metabolized by CYP3A4 & CYP2C19
Donepezil HCl
Aricept
Indication: Alzheimer’s Disease
MOA: reversible acetylcholinesterase inhibitor that works centrally to increase the amount of acetylchoine available at cholinergic synapses.
Duloxetine
Cymbalta
Indication: Major Depressive Disorder (MDD), Generalized Anxiety Disorder (GAD), neuropathic pain
MOA:
potent inhibitor or neuronal serotonin & norepinephrine & a slight inhibitor of dopamine reuptake. It’s MOA is thought to be due to a potentiation of serotonergic & noradrenergic activity in the CNS
Escitalopram
Lexapro
Indication: Depression
MOA: the pure s-enantiomer of citalopram. Highly selective serotonin reuptake inhibitor which blocks the neuronal reuptake of serotonin, but not of norepinephrine or dopamine, into human platelets in the CNS
Fluoxetine HCl
Prozac, Sarafem
Indication: Depression, Obsessive-Compulsive Disorder (OCD), bulimia nervosa, panic disorder
MOA: Blocks the neuronal uptake of serotonin but not of norepinephrine, into human platelets in the CNS .
Gabapentin
Neurontin
Indication: Seizures, postherpetic neuralgia
MOA: Exact MOA is unknown; has antiseizure activity in rats & mice. Excretion occurs by the renal route as unchanged drug.
Lamotrigine
Lamictal, Lamictal XR
Indication: Seizures, bipolar disorder
MOA: Exact MOA unknown; It has weak (or zero) effects on serotonin, adrenergic, dopamine, histamine, opioid, muscarinic, GABA, or adenosine A1 or A2 receptors. It’s MOA may be due to an inhibition of voltage sensitive Na+ channels resulting in a stabalization of neuronal membranes & modulation of presynaptic transmitter release of excitatory amino acids (glutamate & aspartate).
Memantine HCl
Namenda
Indication: Alzheimer’s Disease
MOA: Persistent activation of CNS N-methyl-D-aspartate (NMDA) receptors by the excitatory amino acid glutamate has been hypothesized to contribute to the sympomatology of Alzheimer’s disease. Memantine is thought to exert its therapeutic effect through its action as a low to moderate affintiy uncompetitive (open-channel) NMDA receptor antagonist. It binds preferentially tot he NMDA receptor operated cation channels. It shows little to no affinity fo GABA, benzodiazepine, dopamine, adrenergic, histamine, & glycine receptors or for voltage dependent Ca2+, Na+ or K+ channels. It does show antagonist effects at the 5HT3 receptor & a slight inhibition of nicotinic acetylcholine receptors. Excretion od unchanged drug occurs in the urine by active tubular secretion.
Olanzapine
Zyprexa
Indication: Psychotic disorders, bipolar disorder
MOA: Is thought to be due to selective antagonism of dopmaine & serotonin 5HT2 receptors in the CNS. Is also an inhibitor of serotonin 5HT 2a & 2c, muscarinic M1-5, histamine H1, & adrenergic alpha-1 receptors. First pass metabolism cecreases the amount that reaches systemic circulation by 40%
Paroxetine HCl
Paxil, Paxil XR, Pexeva
Indication: Depression, Obsessive-Compulsive Disorder (OCD), panic disorder
MOA: Highly selective inhibitor of neuronal serotonin uptake. It weakly inhibits Norepinephrine & dopamine neuronal reuptake. Steady state concentrations are achieve in abotu 10 days. ~95% bound ot plasma proteins & is a substrate for P-450 hepatic isoenzyme CYP2D6. Metabolized in the liver & excreted in teh urine (64%) & in the feces (36%)
Pregabalin
Lyrica
Indication: Neuropathic pain, seizures, fibromyalgia
MOA: may be realted to it’s high binding affinity to alpha(2)-delta site in CNS tissues. Well absorbed after oral administration/ eliminated by renal excretion. Does not bind to plasma proteins.
Quetiapine
Seroquel
Indication: Schizophrenia, bipolar disorder
MOA: multiple neurotransmitter antagonist with activity at serotonin 5HT1a, & 5HT2, dopamine1 & Dopamine2, Histamine1 & adrenergic alpha-2 & alpha-2 receptors. The MOA of quetiapine is thought to be due to its action at hte Dopamine2 & serotonin 5HT2 receptors.
Sertraline HCl
Zoloft
Indication(s): Depression, Obsessive-Compulsive Disorder (OCD), panic disorder,Premenstrual Dysphoric Disorder (PMDD), social anxiety disorder
MOA:
Inhibition of neuronal uptake of serotonin (5HT). Excretion occurs both through urine & feces. Highly bound to plasma proteins (98%) & is a substate for P-450 hepatic isozyme CYP3A3/4
Trazadone HCl (Desyrel)
Indication: Depression
MOA: Inhibits serotonin uptake by brain synaptospmes therefore increasing hte behavioral effects of the serotonin precursor, 5-hydroxytryptophan. Trazodone is extensively metabolized by the liver.
Venlafaxine XR
Effexor XR
Indicaiton: Depression
MOA: Serotonin-norepinephrine reuptake inhibitor (SNRI)
Amitriptyline HCl
Elavil
