Drug Efficacy in the Treatment of Antipsychotic-Induced Akathisia: A Systematic Review and Network Meta-Analysis
JAMA network open (2024) · Meta analysis · n=492
No association between effect sizes and psychotic severity was found.
The Cochrane review of oral herbal therapies (PMID 24848732) found high-quality evidence from two trials (85 people) that 100 mg a day of an enriched Boswellia serrata extract for 90 days cut pain by 17 points on a 0 to 100 scale against placebo, with fewer adverse events than placebo in one trial. Effectiveness is that pain reduction. A 250 mg dose of enriched extract showed possible benefit in low-quality evidence from a single small study, so it is plotted flat, not higher. Trials of 100 mg Aflapin a day for 30 and 180 days also reduced knee pain against placebo (PMID 35512759, 39700461). A 999 mg dose of a non-enriched extract is a different product and is not plotted. The Cochrane authors state that the optimal daily dose is still to be determined.
