Review of 33 Patients in Whom Sokeikakketsuto was Used to Treat Recurrent Cramps of the Calf

Abstract

Sokeikakketsuto was administered to 33 patients with recurrent cramps of the calf appearing once a week or more and persisting for 2 weeks or more. Treatment response was evaluated 1 month after the start of drug therapy. Patients whose cramps disappeared immediately after starting were regarded as showing a complete response, those with disappearance after 1 month as showing a partial response, those with a reduction to <50% after 1 month as showing a slight response, and those in whom 50% or more of cramps persisted after 1 month as showing no response. A complete response was achieved in 12 patients, a partial response in 11, a slight response in 9, and no response in 1. In 23 (69.6%) of the 33 patients, cramps disappeared within 1 month after the start of drug therapy. In 32 (96.9%), there was a reduction to <50%. In 29 (87.8%) of the 33 patients, cramps disappeared within 3 months, suggesting the efficacy of this drug. Two-package administration in the evening/at bedtime was more effective than 1-package administration for controlling cramps of the calf at night until early in the morning. The intensive pre-attack administration of 2 packages before sleep was the most effective. Sokeikakketsuto may be useful for treating recurrent cramps of the calf.
