Patho-Pharm midterm 2 Flashcards
What is the food and drug act
where all definitions come from, protects consumers from contaminated altered and unsafe drugs that are not yet approved
Controlled drug and substance drug act
Regulates possession, sales, and manufacture of certain drugs.
Are there refills on narcotics
No
New drug development
The pre-testing, clinical investigational drug studies there are 4 phases
Phase 1 - safety
done on healthy people, evaluate pharmacokinetics
Phase 2
Used on a limited scope only those with problems
Phase 3 - long term impacts
done on large groups of 10 thousand, and see what happens. Keep record for 25 years
Phase 4 - post-marketing studies
ways to get doctors to prescribe stuff, samples etc.
Special accesses program
If you have a drug people want but have not gone through the phases of the trial yet. But they are dying.
Limited access program
someone with cancer saw a trial work somewhere else, but it can’t be prescribed yet.

bipolar
people who are sick, they are in the crazy section. Severe problems. Psychotic disorder
Benzodiazepines
Pure sedatives, muscle relaxants, can be used in seizures, very effective, short-term, or long-term. Depress activity in the brainstem.
Three types of benzodiazepines
Alprazolam (Xanax)
Diazepam (Valium)
Lorazepam (Ativan)
Alprazolam (Xanax)
fast on set, fast come off, for panic attacks, a poor choice for long-term use, addictive and habit forming. (not great for generalized anxiety)
Averse effects for Alprazolam (Xanax)
confusion, ataxia, headache. Has poor interactions with alcohol and oral contraceptives
diazepam (Valium)
don’t use often, isn’t as good anymore, very effective for seizures, only available in deploy form, (IF A PERSON IS HAVING MUSCLE SPAMS, benzo will get rid of it for short term)
Adverse effects for diazepam (Valium)
avoid patients with hepatic dysfunction, those who drink alcohol and oral contraceptives. Often causes headache, confusion, slurred speech
Lorazepam (Ativan)
very common, fantastic, helps with sleep, and anxiety, 30 minutes onset, comes off after 6 hours, comes in sublingual form, and comes down faster apparently. Very effective, most first choices for seizures can be given any route. Habit forming. (good for agitation) (people who are palliative used for pain control or slight sedation) (used for alcohol with drawl)
Adverse effects of benzodiazepines
Decreased CNS activity, sedation, amnesia
Hypotension
Drowsiness, loss of coordination, dizziness, headaches
Nausea, vomiting, dry mouth, constipation
Benzodiazepines overdose
does not exist, flumazenil may be used to reverse the effects of benzodiazepines
Benzodiazepines Interactions
Alcohol and CNS depressants can result in additive CNS depression and even death. (THESE ARE THE PEOPLE WHO DIE, sympathetic effect together) (died by combining them)
Interactions are more likely to occur in patients with renal or hepatic compromise.
Anxiolytic drugs
Benzos, reduces anxiety by reducing overactivity of the central nervous system
True or false you can administer anxiolytic can be administered with MAIOs
false
Buspirone
anxiolytic, non-sedating, may cause serotonin syndrome
Affective Disorders
(Mood Disorders)
Changes in mood that range from mania (abnormally pronounced emotions) to depression (abnormally reduced emotions)
Some patients may exhibit both mania and depression: bipolar disorder (BPD)

(out of touch with reality, can’t figure out what’s real and not real)
Severe emotional disorder that impairs the mental function of the affected individual to the point that the individual cannot participate in activities of daily living.
Examples of psychosis
Schizophrenia (controlled or uncontrolled) (deploy medications stuff that sticks around)
Depressive and drug-induced psychoses
Mood-Stabilizing Drugs
Mood stabilizers are the Lithium used for bipolar, nothing for anything but bipolar, must do drug levels on) (mood stabilizer) (needs therapeutic levels)
Mood-stabilizing can be used with
benzos, antipsychotics, antiepileptics, and dopamine receptor anoints
Lithium
is a mood-stabilizing drugs,used for bipolar and hypomania.
Frequent drug tests till stable then every three months
Thought to potentiate serotonergic neurotransmission
Narrow therapeutic range
what is the drug of choice for the treatment of mania
Lithium
Side effects of lithium
Can cause cardiac dysrhythmias, can cause long term hypothyroidism, drowsiness, slurred speech, seizures, ataxia and hypotension
Antidepressants is also known as
major depressive disorder
true or false falls are prone in older adults taking antidepressants
True, due to postural hypotension
Tricyclic antidepressants
Inhibition of serotonin and norepinephrine reuptake into nerve endings. It may help regulate the malfunction of neurons, used for neuropathic pain, insomnia, orthostatic hypotension, insomnia, bedwetting, OCD, and anorexia.
what have replaced tricyclic antidepressants
SSRI
what is amitriptyline (Elavil)
Oldest and most widely used of all the tricyclic antidepressants

Neuropathic pain
Insomnia
Fibromyalgia patients
Childhood bedwetting
OCD
Overdose of tricyclic antidepressants
Overdose is lethal 70 to 80% die before reaching the hospital.
CNS and cardiovascular systems are
mainly affected.
Death results from seizures or dysrhythmias. most common
MAOIs and Tyramine
can cause life-threatening reactions
Ingestion of foods or drinks with tyramine leads to hypertensive crisis, which may lead to cerebral hemorrhage, stroke, coma, or death
Tyramine
foods that contain tyramine. (aged cheese, smoked foods, yeast extracts, red wines, Italian broad beans (fava).
MAOIs stand for
monoamine oxidase inhibitions
MAOIs
Prevent the breakdown of serotonin, norepinephrine, and dopamine
MAOIs are used for
Parkinson’s disease, rarely used for depression

insomnia (partly caused by reduced rapid eye movement sleep), weight gain increased appetite, and sexual dysfunction
what are some symptoms for serotonin syndrome with second-generation antidepressants
delirium
agitation
tachycardia
sweating
myoclonus (muscle spasms) excess muscle spasms
SSRI what do they do
an antidepressant that inhibits the reuptake of serotonin in the brain, used to treat depression, anxiety, panic disorders, OCD, and PTSD, less severe side effects, more tolerable, less cost-effective
Types of SSRI
fluoxetine (Prozac)
Sertraline (Zoloft)
Paroxetine (Paxil)
fluoxetine (Prozac)
