In this randomized, 2-way crossover study, the potential for interaction was investigated between atorvastatin and ximelagatran, an oral direct thrombin inhibitor. Healthy female and male volunteers (n = 16) received atorvastatin 40 mg as a single oral dose and, in a separate study period, ximelagatran 36 mg twice daily for 5 days plus a 40-mg oral dose of atorvastatin on the morning of day 4. In the 15 subjects completing the study, no pharmacokinetic interaction was detected between atorvastatin and ximelagatran for all parameters investigated, including melagatran (the active form of ximelagatran) area under the plasma concentration versus time curve (AUC) and maximum plasma concentration, atorvastatin acid AUC, and AUC of active 3-hydroxy-3-methyl-glutaryl-coenzyme-A (HMG-CoA) reductase inhibitors. Atorvastatin did not alter the melagatran-induced prolongation of the activated partial thromboplastin time, and both drugs were well tolerated when administered in combination. In conclusion, no pharmacokinetic or pharmacodynamic interaction between atorvastatin and ximelagatran was observed in this study.

Serum levels of lipids and lipoproteins were examined in individuals with hyperlipidemia treated with atorvastatin or colestimide and in healthy volunteers. Modified low-density lipoprotein (LDL) was measured by its faster electrophoretic mobility and expressed as charge modification frequency (CMF). Serum levels of total cholesterol (t-chol), triglyceride (TG), very low-density lipoprotein (VLDL)-chol, low-density lipoprotein (LDL)-chol, and CMF were significantly higher in hyperlipidemia, but there was no significant difference in serum high-density lipoprotein (HDL)-chol levels between hyperlipidemic and healthy subjects. Treatment with atorvastatin resulted in significant decreases of serum t-chol, TG, and LDL-chol levels but not serum HDL-chol and VLDL-chol. Treatment with colestimide significantly reduced serum t-chol, HDL-chol, and LDL-chol levels but not those of TG and VLDL-chol. CMF was significantly reduced by treatment with atorvastatin but not by colestimide. Atorvastatin significantly reduced plasma levels of thrombomodulin, thrombin antithrombin complex (TAT) and tissue type plasminogen activator-plasminogen activator inhibitor-I complex. Colestimide moderately prolonged activated partial thromboplastin time and reduction of TAT. Based on its actions of lowering modified LDL and improving hemostatic abnormalities, we postulate that atorvastatin might inhibit the onset of ischemic diseases.
