  • GLP has a half-life of &lt; 2 min so it can’t be used as therapy. Necessary to use analogs exenatide clinical effects last up to 8 hours
  • At low titers, the antibodies do not affect the effectiveness of exenatide. Delays gastric emptying. Counsel patients to take their other meds 1 h before byetta
  • Most patients fail lifestyle interventions so the consensus panel decided they should be put on metformin at the same time
  • Important in both inpatient and outpatient setting
  • Secretagogues not considered synergistic when given with insulin
  • There aren’t many head-to-head comparisons of the ability of the different agents to achieve glucose control
  • Approximately 5,000 Patient included for 1,000 years of follow-up in this study Incidence rates and 95% confidence intervals for myocardial infarction and microvascular complications by category of updated mean haemoglobin A1c concentration, adjusted for age, sex, and ethnic group, expressed for white men aged 50­54 years at diagnosis and with mean duration of diabetes of 10 years
  • Atherosclerosis = plaque formation Essential hypertension = no identifiable cause for hypertension Part of syndrome X (metabolic syndrome) especially when hypertriglyceridemia and decreased HDL are included
  • If diabetic patient is initially between 130-140/80-90 you may begin lifestyle adjustment for 3 months if you feel your patient will return to clinic. If goal not achieved, then you must initiate pharmacotherapy management
  • ACE-I, ARB and Thiazide diuretic medications preferred combo = Monitor Renal function and Potassium (Hyper-K ACEI/ARB and Hypo-K HCTZ) ACE-I vasodilate at the efferent arteriole Non-DCCB = Verapamil/Diltiazem SBP &gt; 160 or DBP &gt; 100 requires immediate drug therapy
  • Treatment with aspirin: 30% decrease in myocardial infarction 20% decrease in stroke Not studied in person &lt; 30 and person &lt; 21 = increased chance of Reyes Symdrome
  • ACE-I vasodilate at the efferent arteriole Non-DCCB = Verapamil/Diltiazem
  • Pulses: dorsalis pedis and posterior tibialis
