| answer | definition |
|---|---|
| Glipizide (Glucatrol) | 2nd gen. sulfonylurea; Type 2 DM; |
| glucatrol MOA; | Stimulate pancreas to release insulin and transport extra glucose in the blood to the muscles, liver, and adipose tissues |
| Glipizide (Glucatrol) SE | Agranulocytosis, hemolytic anemia, thrombocytopenia, cholestatic jaundice; Nausea, epigastric fullness, heartburn; erythema, photosensitivity, hypoglycemia, morbilliform and maculopapular eruptions |
| Glipizide (Glucatrol) CI | Hypoglycemic effect is increased when taken w/ alcohol, steroids, beta-blockers, MAOIs, oral anticoagulants, sulfonamides; contraindicated in pts w/ hypersensitivity to sulfonylureas,and juvenile diabetes; cautious use with geriatrics; cardiac/renal/hepa |
| Metformin (Glucophage) class and indication | Biguanide - for type2 DM |
| Metformin (Glucophage) MOA | Inhibits hepatic glucose production and increases uptake |
| Metformin (Glucophage) SE | Ab. bloating, nausea, cramps, feeling of fullness, and diarrhea; metallic taste, reduced B12 levels |
| Metformin (Glucophage) CI | Hypersensitivity to biguanides, hepatic/renal disease, alcoholism, or cardiopulmonary disease; pregnancy, lactation; acidosis, ketoacidosis |
| Acarbose (Precose) class and indic | Alpha-glucosidase inhibitor |
| Acarbose (Precose) MOA | Blunts elevated blood sugar levels after a meal |
| Acarbose (Precose) SE | Flatulence, diarrhea, ab. cramps; do NOT cause hypoglycemia like glucatrol |
| Acarbose (Precose) CI | Hypersensitivity to alpha-glucosidase inhibitors, diabetic ketoacidosis, cirrhosis, inflammatory bowel disease, colonic ulcerations, partial intestinal obstruction, chronic intestinal disease |
| Rosiglitazone (Avandia) class | Thiazolidinedione |
| Rosiglitazone (Avandia) MOA | Decrease insulin resistance – directly stimulate peripheral glucose uptake and storage and inhibit glucose and trigly. production in the liver |
| Rosiglitazone (Avandia) SE | Weight gain, edema, mild anemia |
| Rosiglitazone (Avandia ) CI | possible hepatic toxicity – measure ALT q treatment, q 2 months, and periodically thereafter |
| Nursing Process and Teaching Tips for Oral Antidiabetic Agents | Take Precose with first bite of each meal. |
| Nursing Process and Teaching Tips for Oral Antidiabetic Agents | Take Glucatrol 30 minutes q meals. |
| Nursing Process and Teaching Tips for Oral Antidiabetic Agents | Teach pt how to measure their blood glucose level with a glucometer and perform this as ordered by the MD. |
| Nursing Process and Teaching Tips for Oral Antidiabetic Agents | Drug interactions w/ oral antidiabetic agents include warfarin, aspirin, digoxin, insulin, diuretics, beta-blockers, CCBs, corticosteroids, Phenobarbital, sulfanamides, chloramphenicol, MAOIs, and NSAIDs. |
