Is valproic acid effective in migraine prophylaxis at low serum levels : a prospective open-label study?
Due to the lack of additional benefit from higher valproic acid doses (more than 600 mg per day), we recommend daily valproic acid doses of 500 to 600 mg with a target serum level less than 50 microg/mL for the prophylactic treatment of migraine.
The combined use of ticlopidine, ASA and heparin effectively controls activation of coagulation in patients with stable or unstable angina undergoing coronary dilation.
