Abstract
STUDY OBJECTIVE: To determine the effect of Niaspan--a niacin preparation with both immediate- and extended-release characteristics--on lipid and glycemic control in patients with type 2 diabetes. DESIGN: Retrospective study. SETTING: Private-practice endocrinology group. PATIENTS: Thirty-two patients (mean age 60 yrs; 72% men) with type 2 diabetes identified by a computerized text search. INTERVENTION: Patients received Niaspan 1000, 1500, or 2000 mg/day (median daily dosage 1000 mg). MEASUREMENTS AND MAIN RESULTS: Total cholesterol, low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) cholesterol, triglycerides, hemoglobin A1c, and transaminase levels were compared for each patient before and 6 months after initiation of Niaspan. Niaspan therapy was associated with a significant 34% increase in HDL (p=0.033), a significant 36% reduction of triglycerides (p=0.049), and no significant change in LDL (p=0.236) or total cholesterol (p=0.122). Mean hemoglobin A1c levels significantly decreased from baseline by 0.5 +/- 0.3% (p=0.032), even though dosages and treatment with antidiabetic agents remained constant. There were no significant changes in transaminase levels. Seven patients (21.9%) discontinued Niaspan; one of them experienced an increase in blood glucose while receiving the agent. CONCLUSION: For most patients with type 2 diabetes, Niaspan is a safe and effective therapy for dyslipidemia and does not exacerbate glycemic control.
