Efficacy and Safety of Polaprezinc (Zinc Compound) on Zinc Deficiency: A Systematic Review and Dose-Response Meta-Analysis of Randomized Clinical Trials Using Individual Patient Data
Nutrients (2020) · Meta analysis
The dose-combined overall polaprezinc increased the change from baseline by a mean of 9.08 µg/dL (95% confidence interval: 5.46, 12.70; heterogeneity: I2 = 0.61%) compared to the placebo.
Doses are polaprezinc a day, added to standard triple therapy. In a 303-patient RCT, 75 mg or 150 mg twice daily (150 or 300 mg a day) raised eradication to 77.0% and 75.9% versus 58.6% with triple therapy alone, with no difference between the two doses and more adverse events at 300 mg (5.1% versus 2.8%) (PMID 28407007). A smaller RCT of 300 mg a day with a different triple regimen found no significant gain (80.4% versus 78.2%) (PMID 15786539). A meta-analysis of 3 trials (396 patients) found higher eradication with polaprezinc (OR 2.01) but did not compare doses (PMID 36235778). The curve is flat above 150 mg because the higher dose added nothing.
