What is the effect of cilostazol on symptomatic intracranial arterial stenosis?
The multicenter double-blind placebo-controlled trial of cilostazol in symptomatic intracranial arterial stenosis demonstrated that cilostazol was effective in preventing the progression of the symptomatic intracranial arterial stenosis (Kwon SU et al., 2005). The study found that patients treated with cilostazol showed significant improvement in the degree of stenosis, with a mean reduction in stenosis of 5.2 percent in the cilostazol group compared to a 0.6 percent reduction in the placebo group.
