Answer:
unpleasant feeling that often precedes vomiting
Question 2:
Emesis
Answer:
forcible emptying of gastric, and occasionally intestinal contents
Question 3:
Antiemetic drugs
Answer:
used to relieve nausea and vomiting
Question 4:
Voming center
Answer:
Medulla
Question 5:
Chemoreceptor trigger zone
Answer:
gastrointestinal tract, labrynth (inner ear), and Cerebral Cortex
Question 6:
Antiemetic and Antinausea Drugs Mechanisms of action
Answer:
many different mechanisms f action,
most work by bocking one of the vomiting pathways, thus blocking the stimulus that induces
vomting
, Question 7:
Antiemetic and Antinausea indications
Answer:
specific indications vary per class of antiemetics,
general use for each type: prevention and reduction of nausea and vomiting
Question 8:
Antiemetic and Antinausea drugs
Answer:
Anticholinergics, Antihistamine, antidopaminergics, prokinetic, serotonin blockers,
tertahydrocannabinoids
Question 9:
Anticholinergics Drugs mechanisms of action
Answer:
bind to and vlock acetylcholine receptors in the
inner ear (labrynth), blocks transimttion of nauseating stimuli to CTZ, also block transmission of
nauseating stimuli from the reticular formation to the VC Example: Scopolamine (also used for
motion sickeness)
Question 10:
Antihistamine Drugs Mechanisms of Action
Answer:
inhibits ACH by binding to H1 receptors, prevents
cholinergics stimulation in vestibular and reticular areas, thus preventing nausea and vomting,
also used for motion sickness, nonproductive cough, allergy symptoms, sedation Examples:
dimenhydriinate (Dramamine), diphenhydramine (Benadryl), meclizine (Antivert)
Question 11:
Antidopaminergic Drugs Mechanisms of action
Answer:
block dopamine receptors on the CTZ. also
used for psychotic disorders, intractable hiccups Examples: prochloperazine (Comazine),
promethazine (Phenergan), droperidol (Inapsine) use is controvrisla because of associated
cardiac dysrhythmia
