Abstract/Text 164 patients (m = 45, w = 119; age 55.7 +/- 14.7 years) took part in a multicentric controlled parallel-double blind study in which efficacy and tolerability of the combination quinine sulfate (CAS 6119-70-6) plus theophylline ethylene diamine (CTED, CAS 317-34-0) (Limptar) in the treatment of the recurrent nocturnal leg cramps were investigated. Only patients who suffered before the begin of the study in at least three nights per week from leg cramps were included. The duration of the study was three weeks. In the first week all patients were treated in a single blind design with placebo. The subsequent 2 weeks were carried out double-blind. The global efficacy judged by the physicians and investigated for the 126 patients who took the compounds at least four days within the random phase was remarkably better for the combination than for quinine or placebo (very good and good in 87.1 vs. 63.7 vs. 39.5% of the cases; p less than 0.001; x-test). In 117 patients an analysis of the time course of the efficacy could be done from the notes in the diary (minimum duration of treatment 11 d). Already within the first week there was a highly significant decrease of nights with leg cramps within the CTED group (n = 34) from 4.68 (95% confidential interval 2.26-7.0) to 2.25 (0-6.78) in comparison to placebo (n = 40; from 4.32 [1.9-7.0] to 3.69 [1.22-6.91]) and quinine (n = 43; from 4.78 [2.22-7.0] to 3.27 [0-7.0]; F-test; p = 0.0001 resp. 0.0012).(ABSTRACT TRUNCATED AT 250 WORDS) PMID 2043179 Arzneimittelforschung. 1991 Feb;41(2):167-75.
