Pharmacology Exam 2 Drug List Flashcards
PHENOBARBITAL (Luminal)
TC: antiseizure drug & sedatitive
PC: barbiturate & GABA receptor
**barbiturates depress the CNS at all levels and can help to reduce anxiety
Uses/actions: It enhances GABA (which helps to prevent seizures) and is used for various types of seizures
Side effects: drowsiness, confusion, get a little more anxious and restless
Its a schedule IV drug
In pregnancy category D
Nursing: monitor levels of drowsiness, no driving, are they awake enough to preform their daily activities
DIAZEPAM (Valium)
TC: antiseizure & antianxiety
PC: benzodiazepine & GABA receptor agonist
Actions: suppress activity in the limbic system and RAS (reticular activating systems)
Uses: anxiety, alcohol withdraw, terminates/ends status epilepticus.. you can repeat giving this drug every 10-15 minutes
Side effects: drowsiness
Schedule IV drug
Antidote: flumazenil (Romazicon)
GABAPENTIN (Nuerontin)
TC: anticonvulsant, antineuralgic
PC/action: it increases the synthesis or accumulation of GABA
Used for: seizures, restless leg syndrome, peripheral neuropathy
Side effects: fatigue and drowsiness
PHENYTOIN (Dilantin)
TC: antiseizure, antidysrythmic
PC: hydantoin (sodium influx depressor)
Action: affects sodium channels and decreases the spread of electrical discharge
Used to prevent most all types of seizures
Side effects: heart dysrhythmias and more, confusion, slurred speech, drowsiness, Steven Johnson syndrome (reaction of the skin, flu like symptoms, rash, swelling of the tongue and face)
** this is the most commonly prescribed medication for seizures
FOSPHENYTOIN (Cerebyx)
TC: anti seizure
PC: hydantoin
Action: stabalizes neuronal membranes
Used for seizures and shot term substitution for oral phentoin
** once its in the body it acts exactly the same as Dilantin and can be given IM or IV
IMIPRAMINE (Tofranil)
TC: antidepressant
PC: tricyclic antidepressant (TCAs)
Action: blocks the reuptake of both norephinephrine and serotonin
Use: used for depression, nocturnal enuresis (bed wetting)
Side effects: sedation, orthostatic hypotension
SERTRALINE (Zoloft)
TC: antidepressant
PC: Selective Serotonin Reuptake Inhibitors (SSRIs)
Action: block the reuptake of serotonin
Use: depression, post traumatic stress disorder
Side effect: headache, nausea
PHENELZINE (Nardil)
TC: Antidepressant
PC: Monoamine Oxidase (MAOIs) inhibitor, increases norepinephrine levels
Action: inhibits monoamine oxidase
Uses: depression
Side effects: hypertensive crisis with some foods meaning there are a lot of foods that people aren’t able to have when they are taking Nardil
VENLAFAXINE (Effexor)
TC: antidepressant
PC: serotonin and Norepinephrine Reuptake Inhibitor (SNRI)
Action: SNRI^^
Uses: GAD, SAD, chronic fatigue, depression
Side effects: nausea, drowsiness
LITHIUM CARBONATE (Eskalith)
TC: mood stabilizing drug (bipolar disorder)
PC: glutamate inhibitor, serotonin receptor antagonist
Action: inhibits an excitatory neurotransmitter in the synapse
Use: bipolar disorder, PTSD
Side effects: polydipsia- an increased thirst,
polyuria- an increased amount of urine output, limit caffeine intake, nausea, weight gain
*Essential monitoring of lithium levels is very important, liver and renal studies.. blood levels are drawn in order to monitor these lithium levels
METHLYPHENIDATE (Ritalin)
TC: ADHD drug
PC: CNS stimulant
Action: activate the RAS
Uses: ADHD, narcolepsy, sometimes depression
Side effects: anxiety, insomnia, nervousness, inability to sleep
**Schedule II drug because its often abused and sold
**Should not be taken later in the day so that it doesn’t interfere with sleep
**Worry about weight gain in children
**Avoid stimulants: combining stimulants and caffeine can stimulate your heart rate and cause a fatal dysrhythmia
CHLORPROMAZINE (Thorazine)
TC: antipsychotic or schizophrenia drug
PC: affects dopamine receptor antagonist (so prevents dopamine from reaching the receptors), PHENOTHIAZINE
Action: prevents dopamine from reaching receptors
Uses: psychotic disorders, severe nausea, and vomiting
Side effects: drowsiness, constipation
More specific side effects of phenothiazine
Acute dystonia Akathisia Parkinsonism Tardive dyskinesia Anticholinergic effects Hypotension Neuroleptic malignant syndrome Sedation Sexual dysfunction
HALOPERIDOL (Haldol)
TC: antipsychotic and schizophrenia drug
PC: dopamine receptor antagonist, NONPHENOTHIAZINE
Action: blocks dopamine receptors
Uses: schizophrenia, Tourette’s disorder, emergency sedation, also used for confused elderly people
Side effects: blurred vision, constipation, there’s less sedation so less risk but basically the same as Thorazine
RISPERIDONE (Risperdal)
TC: atypical antipsychotic, schizophrenia drug
PC: dopamine receptor antagonist, ATYPICAL ANTIPSYCHOTIC
Action: weaker affinity for one dopamine receptor
Use: schizophrenia
Side effects: fewer side effects but still signifgicant, effects such as agitation and anxiety
