PEBC Study #1
1. Top Drugs, Conditions & Pharmacology
| Question | Answer |
|---|---|
| what is bioavailability | The fraction (%) of a drug that reaches the bloodstream unchanged |
| what is the first-pass effect | drug metabolizes in the liver before reaching circulation, decreasing bioavailability |
| what are "depot" IM medications | drug formulated to stay in the muscle and slowly release overtime |
| what does it mean when a drug is lipophilic | dissolves well in fats/lipids rather than aqueous/water |
| what does it mean when a drug is hydrophilic | dissolves well in aqueous/water rather than fats/lipids |
| drug class of atorvastatin | statins |
| drug class of rosuvastatin | statins |
| drug class of pravastatin | statins |
| drug class of simvastatin | statins |
| Main 2 indications of statins | Lowers cholesterol and Atherosclerotic cardiovascular disease (ASCVD) risk |
| MOA of statins | they block hepatic (liver) cholesterol synthesis, and the liver pulls more LDL out of circulation. |
| Most notable 2side effects of statins | Myalgia, rare rhabdomyolysis |
| Which 3 statins are affected by grapefruit | Atorvastatin, Simvastatin, and Lovastatin |
| main 3 indication of ACE Inhibitors | hypertension, heart failure, post-MI, chronic kidney disease (CKD) |
| drug class of ramipril | ACE Inhibitors |
| drug class of perindopril | ACE Inhibitors |
| drug class of enalapril | ACE Inhibitors |
| drug class of lisinopril | ACE Inhibitors |
| MOA of ACE Inhibitors | block angiotensin I from converting into angiotensin II → less angiotensin II and less aldosterone → vasodilation and less sodium/water retention |
| Which cardiovascular drug classes are contraindicated in pregnancy? | ACE inhibitors and ARBs |
| Long name for ARBs | Angiotensin II Reductase Inhibitors |
| Most notable side effects (3) of ACE inhibitors | dry cough, hyperkalemia, increased creatinine |
| When are ARBs generally prescribed? | When ACE inhibitors are not tolerated |
| drug class of losartan | ARBs |
| drug class of candesartan | ARBs |
| drug class of valsartan | ARBs |
| drug class of telmisartan | ARBs |
| drug class of irbesartan | ARBs |
| MOA of ARBs | block the angiotensin II receptor → vasodilation and less sodium/water retention |
| Most notable side effects (2) of ARBs | hyperkalemia, increased creatinine |
| What is creatinine? | a waste product from metabolism, high levels in the blood can indicate that the kidneys are not filtering waste effectively |
| main 3 indications of beta blockers | hypertension, angina, post-MI |
| drug class of metoprolol | beta blockers |
| drug class of atenolol | beta blockers |
| drug class of bisoprolol | beta blockers |
| drug class of propranolol | beta blockers |
| drug class of carvedilol | beta blockers |
| MOA of beta blockers | block beta adrenergic receptors → lower heart rate and contractility |
| Most notable 3 side effects of beta blockers | bradycardia (slow heart rate), fatigue, dizziness |
| What time of day should you generally take statins | bedtime |
| Which two body parameters are monitored while patients are on ACE inhibitors | renal function and potassium |
| Why should you not suddenly stop taking beta blockers | can cause abrupt rebound symptoms, including severe hypertension, angina and stroke |
| Which beta blockers are high risk for bronchospasm / bronchoconstriction? | propranolol, nadolol, timolol |
| drug class of nadolol | beta blockers |
| drug class of timolol | beta blockers |
