Diabetes Drugs Flashcards
primary goal of diabetic pharmacology
prevent hyperglycemia and dec chance of long term complications
- maintain tight glycemic control and blood lipid levels
types of insulin
- rapid acting: insulin lispro
- short acting: human regular
- intermediate acting insulin: NPH
- long acting insulin: glargine
insulin administration
subq injection
- sites: back of arms, stomach, thighs
- ordered in units
lispro
rapid acting
- starts working in 15 mins
- peaks in 1 hr
- works for 2-4 hrs
-administer w food
- must be in conjunction w either an intermediate or long acting
insulin regular
short acting
- onset 30-60 mins
- peak 2-6 hr
- duration 3-8 hrs
- give before meals to control hyperglycemia
- often given for tube feeding
- used in insulin infusions
NPH
intermediate acting insulin, neutral protamine hagedron –> protamine helps slow down absorption so that is lasts longer
- onset: 2-4 hrs
- peak: 4-10 hrs
- duration: 10-20 hrs
NPH info
cloudy insulin so agitate before using
- typically injected 2x/day
- can be administered w rapid and short acting
- clear before cloudy
glargine
long acting insulin
- once a day
- onset: 70 mins
- duration: all day
- helps control blood sugar all day so do not mix w other insulins
- often given at night
blood sugar monitoring
need to know blood sugar before administering any type of insulin
insulin pumps
computerized devices with basal infusion of regular insulin
- mostly used for type 1 diabetics
- bolus can be calculated when necessary
- surgically implanted
- still require a FSBG
insulin regimens
most common is the sliding scale
- given based on blood glucose level
- can include basal dose of long acting
- important to educate
insulin complications
- hypoglycemia
- allergic reactions are rare
- lipodystrophies,lipoatrophy
hypoglycemia causes
insulin overdose, dec cal intake, V/D, excessive alc, unaccustomed exercise, childbirth
hypoglycemia s/s
tachycardia, sweating, nervousness, headache, drowsy, fatigue, dec LOC
hypoglycemia treatment
oral carbs, parenteral glucagon, IV dextrose
lipodystrophies, lipoatrophy
depressions of skin at injection sites
- feels hard and changes color
- fat cells harden and no longer absorbs insulin
somogyi effect
overdose of insulin that causes hypoglycemia and counter regulatory mechanisms cause hyperglycemia and ketosis
- usually results from poor management
dawn phenomenon
hyperglycemia in the morning due to natural hormonal release
teaching points of glucose
- monitor glucose level as directed
- carry a good source of carbs in case hypo
- rotate insulin sites
- insulin vials are good for 30 days at room temp
glipizide, glyburide class
sulfonylure
