Praziquantel (pyrazinoisoquinolone) in active cerebral cysticercosis.

A prospective open therapeutic study on volunteers with active neurocysticercosis using pyrazinoisoquinolone (Praziquantel) has shown that it is a safe and effective drug. Objective assessment of the effect of treatment was by high resolution sequential computed tomographic scanning. Sixty-six patients received the drug. Forty-one records were available for complete analysis at the end of 1 year of follow-up. The concomitant use of steroids reduced side effects significantly. A 98% improvement was achieved.
