A person with type 2 diabetes mellitus has elevated blood glucose levels because...
|
-Pancreas does not make enough insulin to control blood glucose
-Liver releases glucagon inappropriately -Muscle cells don't easily take in glucose |
|
Pharmacology (alpha-Glucosidase)
-acarbose (Precose) -miglitol (Glyset) |

-Oral agent for type 2 DM
-Class: Sulfonylureas -Action: Helps body to secrete insulin -Those followed by * are older sulfonylureas which tend to cause more hypoglycemia and are seldom used today |
|
Pharmacology (Sulfonylureas)
-glimepiride (Amaryl) |
-Oral agent for type 2 DM
-Class: Sulfonylureas -Action: Helps body to secrete insulin -Probably safe in patients with kidney disease but elderly should be started on lower-than-usual dose |
|
Pharmacology (Sulfonylureas)
-glipizide (Glucotrol) |
-Oral agent for type 2 DM
-Class: Sulfonylureas -Action: Helps body to secrete insulin -Most effective when taken with meal -May be more effective when taken 30 minutes before meals |
|
Pharmacology (Sulfonylureas)
-glipizide, long-acting (Glucotrol XL) |
-Oral agent for type 2 DM
-Class: Sulfonylureas -Action: Helps body to secrete insulin -Should be taken with meals |
|
Pharmacology (Sulfonylureas)
-glyburide (DiaBeta, Micronase) |
-Oral agent for type 2 DM
-Class: Sulfonylureas -Action: Helps body to secrete insulin -Effects may last entire day -May not be suitable for patients with kidney disease |
|
Pharmacology (Sulfonylureas)
-glyburide, micronized (Glynase Pres Tab) |
-Oral agent for type 2 DM
-Class: Sulfonylureas -Action: Helps body to secrete insulin -More readily absorbed than regular glyburide so strengths of tablets are different |
|
Pharmacology (Sulfonylureas)
-chlorpropamide* (Diabinese) |
-Oral agent for type 2 DM
-Class: Sulfonylureas -Action: Helps body to secrete insulin -Longest-acting drug in this class so has higher potential to cause low blood glucose -Not recommended for elderly or patients with kidney disease -May cause low blood sodium levels, jaundice, possibly skin rashes -*older, seldom used today |
|
Pharmacology (Sulfonylureas)
-tolazamide* (generic only) |
-Oral agent for type 2 DM
-Class: Sulfonylureas -Action: Helps body to secrete insulin -Patients with kidney disease may need smaller doses -*older, used infrequently today |
|
Pharmacology (Sulfonylureas)
-tolbutamide* (generic only) |
-Oral agent for type 2 DM
-Class: Sulfonylureas -Action: Helps body to secrete insulin -An older agent, used infrequently for dibetes |
|
Pharmacology (Thiazolidinediones, TZDs)
-pioglitazone (Actos) -rosiglitazone (Avandia) |
-Oral agent for type 2 DM
-Class: Thiazolidinediones, TZDs -Action: Improves insulin sensitivity of tissues with decreased risk of hypoglycemia -Typically takes 4-6 weeks to see effect on blood glucose -Side effects: Weight gain, fluid retention, heart failure. -MD should perform liver function prior to starting these meds and periodically throughout tx. -May cause women who are not ovulating who have not gone through menopause to start ovulating again, enabling them to conceive -OCPs may be less effective when taking these meds -Avandia carries potential increased risk of MI |
