Study on the Efficacy and Safety of Oral Probucol Tablets in Patients With Hyperlipidemia - Post-Marketing Surveillance

Study Overview
=================
Brief Summary
-----------------
The primary objective of this post marketing surveillance (PMS) is to determine the safety and efficacy of probucol in lowering the level of serum cholesterol in the blood.

Detailed Description
-----------------
This nationwide post marketing surveillance targets to recruit a total of 3,000 patients with hyperlipidemia. Duration of treatment is 60 days. The usual starting dose for Lorelco is 500 mg administered daily, divided into two (2) doses (250mg BID) and given after meals. The dose may be adjusted according to the patient's age and condition. Lipid serum test will be obtained at Day 0 (Baseline). In subjects requiring antihyperlipidemics that fulfill the inclusion criteria, Lorelco 250 BID will be started. There will be 2 follow-up visits after baseline on Day 30 and Day 60. Both lipid serum tests and ECG will be done on these 2 follow-up visits. During each visit the investigator will assess the subject's vital signs and symptoms and check for any adverse events. The primary outcome of measure is the percentage reduction or increase in total cholesterol and triglycerides from baseline values at Week 0 to Week 4 and Week 8 using the following scale: Total Cholesterol Triglycerides Markedly reduced Moderately reduced Slightly reduced Unchanged Increased Reduction of ≥ 15% Reduction of ≥ 10% but < 15% Reduction of ≥ 5% but < 10% Change of < 5% Increase of ≥ 5% Reduction of ≥ 30% Reduction of ≥ 20% but < 30% Reduction of ≥ 10% but < 20% Change of < 10% Increase of ≥ 10% The percentage change on the last week of treatment will be the final evaluation. The secondary outcome is measured by the changes in symptoms and vital signs. Using the following scale: Markedly Improved Improved Slightly Improved Unchanged Aggravated Unknown (not assessable) Safety will be measured by the incidence of adverse events to be collected. Overall efficacy and safety will be evaluated to assess the usefulness of Lorelco using the following scale: Very useful Useful Somewhat useful Not useful Unfavorable Unknown (not assessable)
