Compliance with medication in the Helsinki Heart Study.

Compliance with medication has a decisive influence on the findings in clinical intervention studies, so the reliable estimation of compliance is vital to the success of such research. This report describes the main findings about compliance in the Helsinki Heart Study, a five-year, double-blind, primary prevention trial of gemfibrozil as a lipid-lowering agent compared with placebo, in 4,081 dyslipidaemic middle-aged men. Three estimation methods were employed: capsule counting at every three-month follow-up visit, urine gemfibrozil analysis at six-month intervals, and, a novel technique, a digoxin marker added to both gemfibrozil and placebo capsules at the end of the third and fifth study years. The estimates of compliance for the study population as a whole generated by these three methods are discussed here. The mean daily capsule count showed that 36% of patients on gemfibrozil men and 39% of those on placebo took more than 90% of their capsules, while only 5% of both groups consumed half or less of the prescribed treatment. According to urinary gemfibrozil analysis, 30% of gemfibrozil subjects had more than 90% positive results and 28% had half or fewer positive. Among study completers, there were 42% gemfibrozil subjects and 50% placebo subjects who on both occasions had the good result in the digoxin marker analysis, while 14% of the gemfibrozil men and 12% of the placebo men scored 'poor' in both marker analyses. Capsule counting revealed a slight deterioration in compliance over the trial period, which was confirmed by the other two methods; for example, the proportion of positive results in the semiannual urine gemfibrozil analyses decreased from 76% to 65%. Medication compliance was slightly better in the placebo group according to capsule counting and digoxin marker methods.(ABSTRACT TRUNCATED AT 250 WORDS)

[Evaluation of the efficacy and safety of pravastatin in primary hypercholesterolemia]

Hypercholesterolemia can be a risk factor which engenders coronary heart disease. Today, it seems certain that lowering the cholesterolemia reduces this risk, especially if this reduction is referred to the cholesterol which is linked to the low density lipoprotein, called LDL. It has been demonstrated that the principle way to remove the LDL is by getting it into the hepatocyte through a specific membrane receptor, the research, therefore, has been developed with the aim of pharmacologically modifying the quota of intercellular cholesterol and consequently, in the modulation of the receptivity function by the interference of the LDL uptake, assisting a faster clearance. We can identify a new class of pharmacological drugs, that are the specific inhibitors of the HMGCoA reductase, fundamental enzime in the biosynthesis of cholesterol. This group of inhibitors has recently been enriched by the addition of a new molecule pravastatin. Our task has been to confirm the effectiveness and tolerability of pravastatin, administered for a prolonged period to patients with high levels of cholesterolemia; we have compared it with gemfibrozil, a well-known medicine which has hypocholesterolemic effects. In conclusion, our work, whilst emphasising the expediency of ipolipidic treatment, has undoubtedly proved, that 40 mg of pravastatin in a single evening dose, shows a high degree of efficiency, without side effects. Due to these factors, we can also say that pravastatin prevents, or really induces the regression, of atheroscherotic disease.

Lovastatin and gemfibrozil in the treatment of type 2a and type 2b hyperlipoproteinemia.

Subanalyses of previous multicenter studies comparing lovastatin and gemfibrozil were carried out to evaluate the merits of these agents in patients with different serum lipid phenotypes (type 2a and 2b hyperlipoproteinemia). Regardless of phenotype, lovastatin was more effective in lowering LDL-cholesterol, while gemfibrozil had a greater triglyceride-lowering and HDL-cholesterol-increasing effect. Patients with type 2a phenotype benefited (in terms of serum lipid pattern) more from lovastatin. In type 2b hyperlipoproteinemia, more patients taking lovastatin than gemfibrozil reached both treatment goals defined by the European Atherosclerosis Society, (LDL-cholesterol 4.0 mmol/l and triglycerides 2.3 mmol/l). In many patients these goals could not be met suggesting that multiple drug therapy may be indicated in part of the patients with type 2b hyperlipoproteinemia.
