[The effect of monotherapy with ciprofibrate and in combination with acetylsalicylic acid on the spectrum of lipids, thromboxane and fibrinogen in patients with atherosclerosis and hyperlipoproteinemia].

: Ciprofibrate is one of the basic drugs used to lower risk values of lipid parameters and fibrinogen in atherosclerosis patients. Since antiaggregation treatment with acetylsalicylic acid is a complex part of obligatory therapy of these patients, the authors studied the influence of ciprofibrate on chosen lipid parameters, fibrinogen and thromboxane in monotherapy, and also in combination with acetylsalicylic acid (ASA) in patients with advanced atherosclerosis and hyperlipoproteinemia. In the first group of patients (A-C, n = 12) after one month of low-lipid diet acetylsalicylic acid in a dose of 100 mg was administered daily during a period of 2 months followed by addition of 100 mg of ciprofabrate daily during the next 2 months. In the second group of patients (C-A, n = 11) after one month of low-lipid diet the same drugs were administered but in opposite order. Ciprofibrate was most effective in lowering the levels of triacylglycerids (-41%) and VLDL-cholesterol (-34%), but effectively lowered also the values of total cholesterol and LDL-cholesterol. In both studied groups it led to mild increase of HDL-cholesterol levels. Simultaneous administration of ASA did not significantly influence its hypolipemic activity. Ciprofibrate also significantly lowered the level of fibrinogen (-17%). Increase of the total number of platelets by about 10% was not accompanied by changes of the values and production of thromboxane. Simultaneous administration of ASA caused more than 90% inhibition of thromboxane production in monotherapy and in combination with ciprofibrate. Ciprofibrate is an effective hypolipidemic agent, also lowering the level of fibrinogen. Its combination with ASA is adequate, safe and without negative interaction influencing treatment.
