Diabetes Medications Flashcards
(38 cards)
What is the mechanism of action for Sulfonylureas?
Diabinese, Tolinase, Orinase
2nd Generation: glyburide, glipizide
Increases insulin production (beta-cell stimulator) and increases the sensitivity of receptor sites for interaction c insulin(endogenous insulin secretion)
What is the mechanism of action for meglitinides?
Repaglinide(prandin), and Nateglinide(starlix)
Stimulates release of insulin, it acts more rapidly than sulfonylureas in the presence of glucose.It is a short acting agent that is taken pre prandial to prevent pc glucose elevation
What are the second generation names of Sulfonylureas?
Glyburide, glipizide, and the long acting glimepiride
What are some special considerations for Glipizides? (Glucotrol, Glucotrol XL)
Take 30 minutes before meal, and you may see some capsule in the stool. This is because the capsule is made of a non-absorbable shell.
What is the pt education for Sulfonylureas?
- Adm before meals
- Avoid ETOH
What are some generic names for Meglitinides?
repaglinide(Prandin), and Nateglinide(Starlix)
Which medication has is faster acting c a shorter half life? Sulfonylureas or Meglitinides?
Meglitinides stimulate the release of insulin and act more rapidly than Sulfonylureas c a shorter half life
What are some precautions for Meglitinides? like Repaglinide, and Nateglinide
Not recommended during pregnancy and use cautiously c impaired liver function
What is the pt education for Meglitinides? And side effects?
Adm 0-30 min pre prandial,
SE: hypoglycemia, and weight gain
What is the function of Biguanides? Metformin (glucophage)
Lowers basal and post meal glucose levels in pts c type 2 DM by reducing hepatic glucose production and reducing tissue sensitivity to insulin
What are some generic/trade names of Biguanide?
Metformin hydrochloride(Glucophage), and metformin extended release
What are some precautions for Biguanides? metformin (glucophage)
Big one is hold for 48hrs befor nd after administration of contrast material and surgical procedures requiring anesthesia
What are some contraindications for Biguanide?Metformin (glucophage)
Contraindicated in:
- impaired renal function
- impaired liver function
- > 80 years old
- Pregnancy
- Hypoxia
- CHF
- ETOH abuse
What is the pt education for Biguanides? Side effects? Metformin (glucophage)
Take c 2 largest meals to minimize GI distress
report s&s of fatigue, muscle pain, palpitations, dyspnea, dizziness
SE: diarrhea and nausea
What is the function of Alpha-glucosidase inhibitors? Acarbose (precose), and Miglitol (glyset)
Delays CHO absorption from the small intestine by inhibiting the SI enzyme alpha-glucsidase. Also impairs the breakdown of complex sugars in stomach (means lower post prandial glucose)
What are some generic and trade names of alpha-glucosidase inhibitors?
acarbose(Precose)
miglitol (Glyset)
What pt do you NOT use alpha-glucosidase inhibitor on? Dont use acarbose or miglitol on whom?
Pts c inflammatory bowel disease or any other serious intestinal disorder. Because it acts on the small intestine.
What is the pt education for alpha-glucosidase inhibitors? And SE?
- take c first bite of food
- when taken alone it does not cause hypoglycemia
- can be taken in combination c sulfonylureas or metformin
SE: GI flatulence, diarrhea, and abd discomfort
A pt is taking alpha-gluosidase inhibitors (acarbose) and sulfonylurea and they become hypoglycemic. How do you treat them?
You can treat them c glucose tbs, sublingual glucose gel, or low fat milk rather than products that contain cane sugar which cant be digested and absorbed due to the drugs effect
What is the mechanism of action for Thiazolidinediones? Rosiglitazone (Avandia), and Pioglitazone (Actos)
Reduces insulin resistance at receptors sites so insulin is more efficient. decreases hepatic glucose production
What are some generic and trade names of Thiazolidinediones?
rosiglitzone (Avandia)
pioglitazone (Actos)
What are the precautions of using Thiazolidinediones?
use c caution in pts with hepatic disease
What is the pt education for someone taking Thiazolidinediones? And what are the SE?
take c main meal of the day to maximize absorption
SE: fluid retention, weight gain, H/A, increases cholesterol
Insulin varies according to what 3 factors?
onset of action, peak of action, duration of action
