Drugs Flashcards
Thiazide diuretics
Promote sodium and water excretion and therefore reduce plasma volume and decrease systemic vascular resistance and therefore causing a decrease in BP.
Increases the chances of lithium toxicity. Watch for electrolyte imbalances - hypokalemia
ACE INHIBITORS
- Angiotension-converting enzyme inhibitors (end in ‘pril’– ramapril, captopril, lisinopril)
- Prevents vasoconstriction by blocking angiotension 1 and 2
- Side effects – dry cough, hyperkalemia, taste changes, drowsiness, increased risk of bleeding, bradycardia, depression
ARBS
- Angiotension Receptor Blockers (end in ‘sartan’ – losartan, candesartan, valsartan.
- Prevent the action of angiotensin 11. * Produce vasodilation and increased salt and water excretion
Should be monitored for hyperkalemia and decreased kidney function
*
Calcium Channel Blockers
- Some end in ‘dipine’ – amlodipine, nifedipine, delodopine. Verapamil, diltiazem
- Casuses vasodilation by preventing the movement of extracellular calcium into cells which causes vasodilation and decreased systemic vascular resistance. Increase sodium excretion
- Can cause bradycardia
Beta Blockers
- Affects norepinephrine and epinephrine which blocks the sympathetic nervous system vasodilation and decreased heart rate..
- Monitor HR as it can cause bradycardia. Not a drug of choice for individuals with asthma and COPD as it causes bronchoconstriction. Monitor glucose levels in diabetics
Rapid-acting analogue insulin
(clear)
lispro (Humalog), aspart (NovRapid), and glulisine (Apidra)
Injected 0–15 minutes before meal
Onset: 15min
Peak: 1-1.5hr
Duration: 3-5hr
Short-acting insulin
(clear)
regular
Injected 30–45 minutes before meal
Onset: 0.5-1hr
Peak: 2-4hr
Duration: 5-8hr
Intermediate-acting insulin
(cloudy)
NPH
Onset: 1-3hr
Peak: 6-8hr
Duration: 12-16hr
Extended long-acting insulin
glargine (Lantus), detemir (Levemir)
Onset: 1-2hr
Peak: none
Duration: 24hrs
What insulin can and can’t be mixed
Long-acting insulins (Lantus, Toujeo, Levemir, Tresiba) and Apidra (short acting) CANNOT be mixed with any other insulin.
NPH (intermediate) can be mixed with Humalog, Novolog, (rapid) and Regular (R) insulin.
