5 Clinical Trials for Various Conditions
Statins are a class of drugs given to lower cholesterol. Although statins are considered to be generally safe, some studies show that about 10% of people on statins develop muscle-related symptoms, from fatigue (tiredness), weakness, cramping, pain and sometimes a lifethreatening muscle breakdown condition known as rhabdomyolysis. In some, these symptoms may greatly affect their daily activities. One consideration why symptoms develop in only some patients is that they may have an underlying problem in the way their muscles use fats to produce energy. In these patients, the muscles are not able to fully utilize fats and so they become tired more easily. Fat within the muscle can also affect how your body uses a hormone called insulin, which affects your blood sugar levels. The investigators are specifically interested in previous statin users and determine if the muscle symptoms are related to changes in energy and sugar use. We propose to enroll patients who have developed muscle side effects on previous statin treatment and have since discontinued statin treatment. Our aim is to compare the metabolic parameters in these patients to age and gender-matched normal individuals.
To evaluate the effects of 3-months annatto-derived geranylgeraniol (GG) supplementation on statin-associated skeletal muscle health.
The proposed study will focus on possible effects of statins on muscle strength and why they become tired more easily, quality of life, and measurements to understand why muscles are not able to fully utilize fats. The investigators are specifically interested in statin users and the impact of muscle symptoms on daily activities and quality of life. This study hypothesize that patients with likely statin-associated myopathy have a metabolic dysregulation in fuel utilization such that compared to patients continuing statins, those on placebo will show: 1. improved Individualized Neuromuscular Quality of Life (INQoL) and Short Form-36 (SF-36) scores (primary end point) 2. alleviation of muscle symptoms, 3. increased utilization of fatty acids as a fuel source reflected by the metabolic test results 4. decreased intramyocellular lipid (IMCL) 5. improved insulin sensitivity.
This study will examine the effect of red yeast rice extract compared to pravastatin on muscle related complaints in individuals with high cholesterol who have previously been unable to tolerate statin medications due to muscle pain. The study will determine whether red yeast is associated with a lower level of muscle related complaints compared to pravastatin.
The purpose of this study is to investigate the mechanism of statin-related myopathy by evaluating muscle samples before and after statin exposure.
