We found potential statin-drug interaction with clinically significant level 1 of 36.0%, level 2 of 34.5%  and level 4 of 29.1%.  </span></p><p><span style="font-size: medium;"><strong><span style="text-decoration: underline;">Conclusion:</span></strong> Potential statin-drug interactions were found in drug prescriptions of dyslipidemic outpatients at Srinagarind Hospital.  The levels of documentation were mostly in suspected and probable levels, and in high potential for clinical significance.  Data suggested that an increase in awareness of prescription of statin over drug interactions and monitoring for the adverse effects may improve the therapeutic outcome.</span></p> ER -
