Arm/Group Title Lipid Abnormalities
Hide Arm/Group Description

No comparison groups for this observational study. Patients receive only one type of formulation, then drug exposure was the same for all patients.

This study was conducted in a prospective, single-arm, multi-center format. As this study was observational in nature, the follow-up of subject's was not prescriptive in nature and was according to the judgment of the investigator, within the period of observation set forth in the protocol.

Typically, Niaspan is titrated in the following manner: After Week 8, titrate to patient response and tolerance. If response to 1000 mg daily is inadequate increase dose to 1500 mg daily; may subsequently increase dose to 2000 mg daily. Ideally, Niaspan should not be increased more than 500 mg in a 4-week period and daily doses above 2000 mg are not recommended. It is expected that women may respond at lower doses than men. However, consult with the approved label for titration recommendation in the particular country.

1.Primary Outcome
Title Effectiveness of Niaspan
Hide Description

Increasing serum HDL-C (high-density lipoprotein - cholesterol) levels.

Calculated change in different variables (Difference percent for HDL, LDL, Non-HDL and Triglycerides) was obtained using the expression:

percent.change=((final.visit.variable-baseline.variable.))/(baseline.variable))*100 Then percent change is calculated at 24 weeks regarding baseline for different variables.

Time Frame 24 weeks regarding baseline visit (visit1)

Expected sample size was not achieved due to supply issues with the new formulation in Mexico and the local decision in Colombia to cancel marketing the product in the country.
