in the Islets of Langerhans
-
insulin schedule therapy-
--> conventional therapy
- does not provide tight control
- not based on caloric intake
-
insulin schedule therapy-
--> intensive conventional therapy
pre-prandial dosage adjusted according to caloric intake
adaptable to caloric intake --> tight control

insulin schedule therapy-
--> continuous subQ Insulin Infusion
achieve tight control through use of infusion pump
provide basalar level based on caloric intake

- -lasts 24 hours
- mostly given at night, but time may vary
- DO NOT mix or give IV
- SubQ only
clear solution
-
Glargine / Lantus
- Tx of type I and II diabetes
- once daily subQ 2 same time
Long duration
-
combo insulin
- used for peeps with stable condition
- eliminates need for additional injections
- used subQ only
-
only NPH can be mixed with short acting
-short act: regular, lispro, aspart, glulisine
- only NPH can be mixed with short acting
- -short act: regular, lispro, aspart, glulisine
-
4 complications of insulin use
- hypoglycemia
- hypokalemia
- lipohypertrophy
- allergic rxns
-
what do we need to watch for in a pt. using insulin and Beta Blockers?
beta blockers can mask the S & Sx of hypoglycemia
-
oral insulin is only for type II diabetes and only after diet and exercise don't work
oral insulin is only for type II diabetes and only after diet and exercise don't work
-
Biguanides
mech of action
DOC for intial therapy
- act: lower bld glucose and improve glucose tolerance.
- -inhib glucose production in liver
- -reduce glucose absorp in gut
- -sensitiize insulin recepts in target tissues
-
biguanines
where do they work and what are the therapuetic uses?
work= NOT metabolized, excreted unchanged by kidneys
uses= glycemic control, prevent diabetes, gestational diabetes,
-
biguanines:
side effects
toxicity
interactions
- se= dec. appetite, nausea, diarrhea
- -dec absorp of vit b12 and folic acid
toxic= lactic acid
interact= alcohol inhibits lactic acid breakdown
-
Metformin
drug that is classified as a biguanine
-
Sulfonylureas
introduced as oral antidiabetis meds, but hypoglycemia was major side effect
-
sulfonylureas:
mech of action
therapeutic uses
side effects
- act= stimulate the release of insulin from pancreas
- **doesn't work in type I b/c no insulin is produced
use= Tx type II diabetes
se= hypoglycemia, cardiovascular toxicity, pregnancy and lactation
-
Thiazolidinediones / Glitazones
- also called TZD's
- Decrease insulin resistence
- added on to metformin
- used in Type II
-
Pioglitazone / Actos
ONLY TZD left on the market
- reduce insulin resistence and increase production
- usually combined with Metformin, Sulfonylurea, and/or supplament to insulin
-
Pioglitazone / Actos:
side effects
- upper resp tract infections
- headache
- sinusitus
- myalgia
- HF
- hypoglycemia
-
Pioglitazone / Actos:
drug interactions:
what do you need to do with Actos when you also use inducers? inhibitors?
inducers= higher dose of actos needed
inhibitors= lower dose of actos needed
-
Meglitinides / Glinides
actions and use
- stimulate pancreatic insulin release
- used in mono and combined therapy
-
Repaglinide
a meglitinide
rapid absorption and excretion
can cause hypoglycemia
-
Acarbos
alpha-glucose inhibitor
- acts in the intestine to delay absorption of carbs
- effects do not depend on insulin
se= gas, cramps, abd distention, anemia, liver problems
-
Sitagliptin
- classified: Gliptins
- 3rd line drug
- enhances actions of incretin hormones
- mono or combined therapy
- rapid and complete absorption
- excreted in urine
only used as last ditch effort
-
stagliptin:
side effects
- upper resp trat infect
- headache
- inflamm of nasal and throat
- pancreatitis
- hypersense rxn
-
Pramlintide
new injectable drug for type I and II
-
Exenatide and Liraglutide
new injectable drugs for type II only
- Ex= 1st incretin mimetic
- =improve glucose control
- =nausea is common
- =risk of pancreatitis and kidney trouble
