Summary

A cerebral Ca2+ overload blocker-flunarizine hydrochloride — was used with excellent results for prophylaxis of delayed ischaemic neurological deficit (DIND) in severe subarachnoid haemorrhage.

The drug was administered orally at a dose of 10 mg, four times daily for four days, followed by three times daily for three days and twice daily for 14 more days.

Of 72 patients treated with flunarizine, only one developed permanent DIND. 37 consecutive patients who were in Fisher's group III and were treated with flunarizine from immediately after early surgery were compared retrospectively with the 37 consecutive Control Group patients, who also belong to Fisher's group III. Among the Control Group patients, eight died from DIND and ten developed infarction from DIND, while flunarizine strongly prevented (p<0.001) DIND. Furthermore, the only one DIND was attributable to failure of administration of flunarizine.

There were no side-effects from flunarizine.

The association of severe angiographic vasospasm was less frequent in the Flunarizine Group (18% vs 57%, p<0.02).

From this evidence, it might be concluded that flunarizine significantly inhibits the occurrence of severe neurological deficit due to delayed vasospasm. This highly beneficial effect on severe delayed vasospasm might be attributable to its intense inhibitory action on intracellular Ca2+ overloads especially in severe pathological situations.
