MCW Insulin and Oral Sulfonylureas
Question | Answer |
---|---|
Only insulin suitable for intravenous use; Color of solution is____ | Regular Insulin; clear |
Insulin with a delayed, longer time course; Color of suspension is____ | NPH; cloudy |
Insulin analogs (2) with shorter onset of action and quicker deactivation than regular insulin | Lispro insulin, Insulin aspart |
Long acting insulin analog | Insulin glargine |
Why are intermediate and long-acting insulins administered? | To mimic 24 hour basal insulin secretion |
What are short acting insulins given pre-prandially? | To mimic nutrient stimulated insulin secretion |
Goals of insulin therapy | 1. avoid symptoms of hyperglycemia 2. Keep mean glucose leves as close to normal to prevent long term complications 3. While avoiding severe "hypoglycemic reactions" |
Group of drugs that work by stimulating insulin secretion by the pancreas by directly interacting with the B-cells K+ transporter, causing depolarization and secondarily calcium influx | Sulfonylurea |
Three commonly used sulfonylurea drugs | Tolbutamine, Glipizide, Glyburide "To Get Glucose" |
Major effect of this drug is to make liver more sensitive to insulin | Metformin |
Most serious side effect of Metformin; Avoided by not giving drug to patients with this condition | Lactic acidosis...Potentially FATAL; Renal insufficiency |
This drug makes peripheral tissues such as fat and muscle more sensitive to insulin by activating PPAR | Rosiglitazone |
Rosiglitazone contraindicated in patients with this | advanced heart failure |
This drug inhibits enteric enzymes that break down complex carbohydrates resulting in partial malabsorption of carbohydrates; reduces post-prandial hyperglycemia | Acarbose------glucosidase inhibitors |
Drugs that increase insulin (2) | 1.Oral sulfonylureas (Tolbutamine, Glyburide, Glipizide) 2.Insulin |
Drugs that improve insulin therapy (2) | 1.Metformin 2.Rosiglitazone |
