ATI Capstone Pharmacology Study Guide 2021/2022
Pharmacology can be a tough area to review. There is so much info that
it can be difficult to feel confident. While it is not possible to memorize it
all, having a strong knowledge base of the classifications goes a long way.
The ATI pharm review book is organized by classifications. Medications in
the same classification often act in similar ways. So if you don't know
much about a medication, but you know what classification the
medication belongs to, you will better grasp the action and purpose for
the client's needs.
Here are some helpful tips to help you remember some of your
classifications:
Antiemetics
An antiemetic is a medication used in the treatment and/or prevention
of nausea and vomiting.
Remember generic names are our friend because meds in the same
classification often have similar generic names but brand names can
come and go.
Here are some common classes of antiemetics and their generic names –
notice the similarities in the generic names:
It’s ‘Tron’ to the rescue!
Dopamine antagonists
Promethazine
(Phenergan)
Prochlorperazine
(Compazine)

Metoclopramide (Reglan): Now this one is different in generic name
because it can have some different side effects – watch for extra-
pyramidal side effects with metoclopramide.

Sometimes the generic names are not as helpful and you have to
remember what meds fall under certain classes. Antihistamines and
cannabinoids are used as antiemetics as well:
Cannabinoids
Cannabis - Medical marijuana, in the U.S., it is a
Schedule I drug. Dronabinol (Marinol) - a Schedule III
drug in the U.S.
*Remember most antiemetics can cause sedation so watch out for
additive effect if given with narcotic analgesics and protect your client
from injury.
Proton Pump Inhibitors (PPIs)
PPIs decrease stomach acid by inhibiting those gastric proton pumps that
make the acid – they stop the acid at the pump!
Remember generic names are our friends because meds in the same
class often have similar generic names but brand names come and go:
Pantoprazole (brand names: Protonix, Somac, Pantozol, Zentro)
Think of a pump in your stomach just churning out the acid – ‘Zole’ is the
nice guy
who shuts off the pump.
‘Zole’ is very friendly (well-tolerated by most clients), but can cause vitamin
