Meds Flashcards
Insulins (cont)
Human-derived. Using recombinant DNA
Goal:tight glucose control and reduce incidence of long-term complications
Insulins
Function as a substitute for the endogenous hormone. Effects are the same. Restores the diabetics pts ability to metabolize CHO’s, fats, and proteins. Store glucose in the liver. Convert glycogen to fat stores.
Rapid-Acting
Most rapid onset of action (5-15 mins)
Shorter duration
Pt must eat a meal after inj.
Rapid acting insulins
Lispro (humalog)-similar to endogenous insulin Insulin aspart (novolog) Insulin glulisine (apidra)-newest May be given subQ or via continuous subQ infusion pump (but not IV)
Short acting
Regular
Humulin R
Onset 30-60 mins
Only insulin that can be given IV bolus, IV infusion, or even IM
Intermediate acting
Isophane insulin suspension (NPH)
Cloudy appearance
Slower in onset and more prolonged in duration than endogenous insulin
Long-acting
Lantus and levemir
Clear, colorless solution
Referred to as basal insulin
Combo insulin products
NPH 70% and regular insulin 30% (humulin 70/30, novolin, 70/30, novolog 70/30)
NPH 50% and reg insulin 50% (humulin 50/50)
Sliding scale or reg insulin doses adj. according to blood glucose test results.
Typically used in hospitalized diabetic pt or those on tpn or enteral tube feelings
Sc insulin is ordered in an amt that increases as the blood glucose goes up
Disadvantage- delays insulin admin. Until hyperglycemia occurs-results in lrg swings in glucose control
Oral
Only for type 2
Treatment also includes lifestyle mods
Oral meds will not be effective without lifestyle changes
Biguanides
Metformin-glucophage
tells liver to stop making glucose
lactic acidosis
don’t use 48 hrs prior or after contrast agent
Sulfonylureas
Main side effect is hypoglycemia
First gen-chloropropamide (diabinese) and tolazamide (tolinase)
Second gen-glimepride (amaryl) glipizide (glucotrol) glyburide (diabeta, micronase)
Glinides
Main side effect-hypoglycemia Repaglinide (prandin) nateglinide (starlix) stim. pancreas to release insulin weight gain liver and renal impairment
Thiazolidinediones
Pioglitazone (actos) aka glitazones
sensitize tissues to insulin
increase weight
hypoglycemia
anemia
edema
Alpha-glucosidase inhibitors
Slows movement of food through GI tract
GI effects occur-flatus, indigestion, diarrhea, pain, cramping
Acarbose (precose) miglitol (glyset)
