(23 cards)
Humalog is fast or short-acting insulin?
rapid acting (3-4 hours) aka Lispro
Novolog is a fast or short-acting insulin?
rapid acting (3-4 hours) aka Aspart
Name some long-acting insulin.
long acting (24-35 hours)
Glargine (Lantus)
Levemir (detemir)
How do sulfonylureas work?
increase in the amount of insulin secreted in response to a carbohydrate challenge
Explain the 3 fundamental defects in DM 2.
- decreased peripheral glucose utilization
- increased hepatidc glucose production
- insufficient insulin secretion
how does the mechanism of action of metformin (a biguanide) differ from a sulfonoylurea?
increases peripheral metabolic response to endogenous insulin
What is the mechanism of metformin?
- decreases hepatic glucose production
2. increases peripheral glucose utilization
what is the MOA of NSAIDs?
COX-inhibition and inhibits prostaglandin synthesis
What is COX-1 used for?
important for platelet aggregation, regulation of blood flow in the kidney and the stomach, and regulation of gastric acid secretion
What is COX-2 used for?
induced during pain and inflammatory stimuli
What is the DOC and dosage for acute gout?
Indomethacin 75 mg PO BID
What is the MOA of Mobic?
COX-2 preferential inhibitor (induced during pain and inflammation)
*dosage is 7.5mg PO daily
What lab test monitors heparin?
activated partial thromboplastin time (PTT)
What is the low dose heparin dosage?
5,000 units SC 2 hours prior to surgery and 5,000 SC units every 8-12 hours until ambulatory
what is the reversal agent for heparin?
protamine sulfate
*1mg neutralizes 100 units heparin
what is the lovenox dosage for DVT prophylaxis?
40mg SC
which blood test monitors warfarin?
PT/INR
what is the MOA for Eliquis (Apixaban) and Xarelto (rivaroxaban)?
Factor Xa inhibitors
What is the MOA of dabigatran (pradexa)?
direct thrombin inhibitor
what are the irreversible platelet inhibitors?
aspirin
plavix (clopidogrel)
*inhibits platelet for 7-10 days
which class of local anesthetics is more hypersensitive?
esters> amides
which class of local anesthetics is metabolized by the liver?
amide
*so don’t use amides in patients with cirrhosis
which class of local anesthetics is metabolized in the plasma?
esters (by pseudocholinesterase)
