OBJECTIVE: 1) To assess the efficacy of homeopathic prepared Galphimia glauca compared to placebo in the treatment of pollinosis. 2) To estimate the corresponding overall success rate of Galphimia glauca. Meta-analysis of clinical trials.
STUDY SELECTION: 7 randomized double-blind placebo-controlled trials and 4 not placebo-controlled trials (1 randomized and controlled, 1 prospective uncontrolled, 2 retrospective uncontrolled) performed by our study group between 1980 and 1989. An additional MEDLINE search revealed no further trials on this topic. Exclusion and inclusion criteria were identical over all trials. In total, 1038 ambulatory patients that suffered from acute pollinosis (752 in placebo-controlled trials) entered the analysis.
MAIN OUTCOME MEASURES: Relative frequency and relative risk for showing noticeable and soothing relief in ocular symptoms as assessed by the patient. The overall rate of improved eye-symptoms is about 1.25 (CI: 1.09 to 1.43) times higher in the verum than in the placebo group. Verum success rate is estimated by 79.3% (CI: 74.1% to 85.0%). Across the single studies the results were highly comparable except for the study run in 1985. A significant superiority of Galphimia glauca over placebo is demonstrated. Estimates of verum success rates are comparable with those of conventional antihistaminics, but no side effects occurred. As not all of the single studies were analyzed by intention to treat analysis the results may be biased.
