Memorizing important nursing pharmacology, including drug classifications, is going to help you beyond exams. And having resources at hand – like a pharmacology drug classification chart – will make drug memorization much easier.
Drug classifications are groups of similar-acting drugs that treat related ailments. Getting a wrong drug classification answer on a Pharmacology exam is never good – but giving a patient the wrong drug is way worse.
To help with drug memorization, you can download our Drug Classifications eBook below. But first, take a look at our pharmacology cheat sheet.
Our Quick Nursing Pharmacology Cheat Sheet
Pharmacology cheat sheets can help with exams and coursework during nursing school and real-life nursing after graduation.
Here’s our quick cheat sheet for you that covers common drug classifications, along with reasons and actions:
|Ace Inhibitors||Hypertension||Suppressing the renin-angiotensin-aldosterone system and preventing the activity of ACE, which converts angiotensin 1 to angiotensin 2 (vasoconstrictor). Inhibiting the conversion causes Na+ and H2O not to be retained; as a result, sodium and BP decreases.|
|Angiotensin Receptor Blockers (ARB)||Hypertension||Blocking the binding of angiotensin two at various sites on smooth muscle. Blocking the vasoconstriction effects of the renin-angiotensin-aldosterone system, as a result, causes a decrease in blood pressure.|
|Beta-Blockers||Hypertension, Cardiac arrhythmia, Heart failure, Angina, Glaucoma, Prevention of Myocardial infarction (MI).||Blocking beta receptors in the heart to decrease cardiac workload to decrease HR and dilate blood vessels. Providing membrane stabilizing effects.|
|Calcium Channel Blockers||Hypertension, Angina pectoris, Vasospastic (Prinzmetal’s) angina.||Inhibiting calcium’s movement across the cell membrane of cardiac and arterial muscles – resulting in less calcium available for nerve impulse transmission and relaxing blood vessels to increase 02 supply to decrease cardiac workload.|
|Cephalosporins||Respiratory infections, Otitis media (ear infection), Bone/joint infections, Genitourinary tract, and other bacterial infections.||With their β-lactam ring, they target the bacterial cell wall, making it defective and unstable. This action is similar to the action of penicillin. Cephalosporins are usually bactericidal.|
|Thiazides (Diuretics)||Hypertension, Used with antihypertensives, reducing edema, Glaucoma, seizures, and Renal disease.||Inhibiting reabsorption in the ascending portion of the loop of Henle and early distal tubule. Excrete sodium, chloride, and H2O.|
