Final Flashcards
First-line agent for atrial fibrillation
Warfarin
Nitrofurantoin renal function breakpoint
CrCl <30
Gabapentin and hydrocodone–acetaminophen interaction
increased risk of respiratory depression
Omeprazole Max Use
should be discontinued if the patient has been using it for longer than 8 weeks
Sulfamethoxazole–trimethoprim (TMP-SMX) and Amiodarone interaction
TMP-SMX may decrease the effects of amiodarone
Prazosin and furosemide interaction
Avoid in women because of increased risk of urinary incontinence. Prazosin (Minipress) is an alpha blocker. It lowers blood pressure by relaxing blood vessels.
Vaginal estrogens uses
May be appropriate for recurrent lower urinary tract infections
Use of Escitalopram in combination with Tramadol
Risk of hyponatremia. All SSRIs, including Escitalopram, Fluoxetine, can cause SIADH and could cause hyponatremia, should be used with caution in the depressive patients with regular monitoring of electrolytes, especially in the elderly. (Use SNRI Venlafaxine)
To treat Depression: If 12 years old vs 52 years old
If 12 years old use SSRI (Fluoxetine). If 52 years old use SNRI (Venlafaxine)
Ranitidine renal function breakpoint
CrCL less than 50 mL/min reduce by 50% (ex., was 150 mg reduce to 75 mg)
If Gabapentin dose is 900–3600 mg renal function recommendation
Creatinine clearance must be higher than 80 ml/min
Diphenhydramine/anticholinergic long term use effects
50% increased risk of dementia among people who used a strong anticholinergic drug daily for about three years; long-term use of Benadryl/Diphenhydramine, has been linked to an increased dementia risk/cognitive decline
Colace/Docusate
Stool softener/Surfactant
Milk of Magnesia, Miralax, poly glucol
Osmotic laxatives
Senna, Castor oil
Stimulant laxative
Sucralfate with food or without?
must be administered on an empty stomach
Ciprofloxacin and calcium interaction
Cipro binds to calcium and prevents absorption
Warfarin with low risk of bleeding (INR above therapeutic range but less than 5 but less than 10)
Omit 1-2 doses, resume warfarin at 10-20% lower than original dose. Check INR in 24 hours. Vitamin K is no longer recommended.
Warfarin with higher risk of bleeding (INR greater than 10 with no serious bleeding)
Hold Warfarin and give vitamin K 3 to 5 mg (5 to 10) ORALLY. Check INR in 24 hours. If still high, administer vitamin K1 1-2mg PO. Resume warfarin at 10-20% lower than original dose when the INR is within therapeutic range.
Serious bleeding (INR results are greater than 10)
Hold Warfarin, vitamin K should be given by slow IV INFUSION in a dose of 5 to 10 mg (10mg slow IV plus fresh plasma or prothrombin complex concentrate, depending on urgency). Check INR in 24 hours. Repeat Vitamin K1 every 12 hours as needed. Resume warfarin at 10-20% lower than original dose when the INR is within therapeutic range.
If the INR is too low (titration)
Total weekly dose is adjusted upward by 10% and the INR is rechecked in 2 weeks.
DECREASE DEMAND OF INSULIN: Medications That Increase Glucose Levels > (hyperglycemia > need more insulin dose/increases insulin requirement)
Steroids/Glucocorticoids (Prednisone, Hydrocortisone)
Phenytoin
Protease Inhibitors (HIV treatment)
Niacin (vitamin B)
Obesity (reduces # of receptors/insulin resistance > need more insulin)
INCREASE DEMAND OF INSULIN > INCREASE RISK FOR HYPOGLYCEMIA because they increase affinity (binding ability) of the insulin receptor > increases risk for hypoglycemia
Levothyroxine, Growth hormone (GH), ACEIs, ARBs, aspirin, beta-adrenergic blockers, bromocriptine, fibrates, fluoxetine, linezolid, MAOIs, SSRIs, Alcohol, pentoxifylline, psyllium, salicylates, selegiline, Sulfonamides, testosterone ALL increase hypoglycemic effect of insulin, including inhaled forms
GLUT-1
ALL tissue: blood/brain
red blood, pancreas, brain, liver, kidney, muscle, adipose tissue, epithelial cells of small intestine, neurons
Basal uptake
blood-brain barrier
related with insulin resistance inT2DM
primary influence in exercise
