Cards

Term
Spasm
Definition
peripheral and is caused by pain/injury/stress. viscious cycle of spasm <-->pain.
Term
Spasticity
Definition
CNS. increased tone. firing of motor cortex. Loss of inhibition from above, velocity dependent.
Term
What are the sedatives?
Definition
Valium, Lioresa, Soma, Flexeril, Norflex.
Term
Which Central-acting Drug (sedative) can be used for both spasm and spasticity?
Definition
Valium. Cns at all levels by enhancing GABA.
Term
Which central acting drug will work for spasticity only?
Definition
Lioresa. Action at the level of the spinal cord.
Term
What central acting drugs are used for Spasms only?
Definition
Soma, Flexeril, Norflex. pharmacodynamics not fully understood.
Term
What drugs should be avoided when using "spasm-only" central-acting drugs?
Definition
Avoid barbiturates as a skeletal muscle relaxant, ADRs too harsh and more dramatic.
Term
What are the ADRs of all Central Acting Drugs (Sedatives)?
Definition
Sedation!, CNS depression, hepatic toxicity, physical dependence - will need to ween off.
Term
What are the drug-drug interactions that Central acting drugs have?
Definition
Other CNS depressants(antihistamines, Etoh)
Term
What are the peripheral acting drugs?
Definition
Dantrolene, Tubocurarine HCL, Anectine
Term
What is Dantrolene taken for and what is its action?
Definition
For spasticity as a peripheral-acting drug. blocks Ca++ release from SR of skeletal muscle.
Term
What are the ADRs of Dantrolene?
Definition
hepatic toxicity, muscle weakness, drowsiness, diarrhea.
Term
What is Tubocurarine HCL taken for and what is its mechanism of action?
Definition
For intubation, mechanical ventilation, tetanus. Non-depolarizing: competes with Ach for nicotinec binding sites on motor end plate and blocks stimulation.
Term
What is Anectine taken for and what is its mechanism of action?
Definition
surgery, electroshock therapy. Depolarizing. bind to nicotinic-2 receptors on motor end plate to depolarize muscle fiber and stays bound to prevent repolarization.
Term
Epilepsy
Definition
seizure disorder: TBI, fever, other disease can cause seizures too, shock, hypoglycemic, electrolyte imbalance, metabolic changes.
Term
Grand Mal seizure
Definition
tonic, clonic muscle contraction
Term
Petit Mal
Definition
absence seizure, zoned out, no awareness.
Term
Febrile Seizure
Definition
short duration due to a fever.
Term
What are the general pharmacodynamics of antiepileptic drugs?
Definition
1. decrease excitability if neuronal membrane 2. GABA binding medications (agonist) 3. Drugs interact w/ Na 2+, Ca2+ to hyperpolarize membrane.
Term
General drug-druge interactions of antiepileptic drugs?
Definition
muscle relaxors (additive), CNS depressants, anti-histamines, opioids, alcohol, stimulants may Counteract.
Term
What are the general ADRs of antiepileptic drugs?
Definition
Sedation, lethargy, drowsiness, depression of brain, dizziness.
Term
Hydantoin drug example
Definition
Dilantin
Term
Barbiturate example
Definition
Luminal
Term
Valproic Acid
Definition
depakene
Term
Iminostilbenes:
Definition
Tegretol
Term
Succinimide:
Definition
Zarontin
Term
Succinimide:
Definition
Zarontin
Term
Oxazolidinediones
Definition
Tridone
Term
Benzodiazepine:
Definition
Valium
Term
What are benzodiazepines that are anxiolytics?
Definition
Xanax, Ativan, Valium.
Term
What is an example of a Non-benzodiazpine used as a anxiolytic?
Definition
Buspar
Term
What are the two types of first generation anti-depressants?
Definition
Tricyclic antidepressants (elavil), Monoamine oxidase inhibitors (phenelzine).
Term
What are the Second Generation Antidepressants?
Definition
Prozac, Paxil, Zoloft.
Term
What is the mechaniism of second generation antidepressants?
Definition
SSRIs. Blocks presynaptic uptake of serotonin. elevated levels in synapse.
Term
What is the action of Tricyclic antidepressants
Definition
Blocks the presynaptic nerve terminal reuptake of many neurotransmitters. Eleveated NE, dopamine, serotonin in synapse for postsynaptic receptors.
Term
What is the action of MAOIs?
Definition
Inhibits enzyme that degrades catecholamine neurotransmitters. Elevated NE, dopamine, sertonin.
Term
What are the ADRs of MAOIs?
Definition
C-V effecs more common, GI, dry mouth.
Term
What is an example of SNRI (norepinephrin and serotonin)?
Definition
Wellbutrin, Zyban. weak blocker of neural uptake of serotonin and NE. Adjunct for smoking cessation. ADRs: GI, agitation, insomnia.
Term
What are some of the causes of Bipolar disorder?
Definition
manic episodes may be caused by cation imbalances, goal is to find balance.
Term
What are the mood stabilizing drugs?
Definition
Duralith, Depakene, Depakote, Tegretol
Term
What is the mechanism of Duralith?
Definition
accelerates catecholamin destruction, inhibits release of nt, decreases sensitivity of postsynaptic receptor.(corrects overactivity)
Term
What is the mechanism of Depakene in bipolar disorder?
Definition
more rapid acting. increases bioavailability of GABA. Test for liver function.
Term
What is the use of tegretol in treatin bipolar disorder?
Definition
anticonvulsant. off-label use = psychiatric disorder.(bipolar, resistant schizophrenia)
Term
What are the 4 ways to treat bipolar disorder?
Definition
Mood-stabilizing drugs, antidepressants, combination of drugs, Electroshock therapy.
Term
What are the three conventional anti-psychotic drugs and the three atypical anti-psychotic drugs?
Definition
(Thorazine, Vesprin, Haldol)conventional. (Risperdal, clozaril, Dopamine system stabilizers) atypical.
Term
What are the ADRs of 1st generation anti-phsychotics?
Definition
sedation, anticholinergic, seizures, weight gain, extrapyramidal symptoms.
Term
What is the 2nd generation anti-psychotic mechanism?
Definition
high affinity for dopamine receptor. more motor side effects.
Term
What is the mechanism of 3rd generation anti-psychotic?
Definition
broader spectrum of action, for resistant schizophrenia. Less EPS side effects, but increased CV risks.
Term
/What is the mechanism of action for 4th generation anti-psychotic?
Definition
acts as dopamine stabilizer (blocks but also mildly acts as dopamine). minimal ADR.
Term
What are the drug-drug interactions of anti-psychotics?
Definition
CNS depressants, parkinson's medications, anticonvulsants, anti-HTNs
Term
What are the three medications for sleep disorders
Definition
Benadryl, Benzodiazepines, Seconal:schedule II. 2&3 can have paradoxical excitement in elderly and young
Term
What are some medications for ADHD?
Definition
Ritalin/Concerta. Amphetamine Sulfate. Desoxyn, Caffeine, Nicotine, Ecstasy.
Term
Pharmacodynamics of ADHD drugs.
Definition
increased catecholamines at synapse. block reuptake of catecholamines.
Term
