Acarbose
Oral Antidiabetic Agent
MOA: Blocks pancreatic amylase (prevents sucrose break down)

Hypoglycemia
Causes:
- Too much insulin or oral agent
- Too little food, vomiting, diarrhea
- physical activity without proper carb loading
Definition
-BG < 70 mg/dL
Signs/Symptoms
Early:
-anxiety, diaphoresis, cold/clammy skin, shakiness, -palpitations (tachycardia)
Late:
-AMS, slurred speech, poor coordination, drowsiness, difficulty arousing from sleep, seizure/coma, death within minutes
beta-blockers reduce HR & anxiety hence making it difficult for the patient to report palpitation
64
Hypoglycemia Treatment
If patient is fully awake and can safely swallow:
- apple juice (dissolved sugar in water), sugar candy
- recheck BG in 15 min, if <75 retreat
- follow with some protein (peanut butter sandwich)
If patient is lethargic/drowsy (needing verbal or tactile stimulation to open eyes)
- should NOT take anything by mouth (high risk of dysphagia & aspiration)
- 1 mg glucagon IM => stimulate liver to release glucose; onset of action: 10 min
- 25-50 ml of 50% dextrose in water (D50); assure patent -IV site; onset of action: 1 min
