It should be noted that this signal of increased cardiovascular mortality in association with long-term use is potentially less relevant for chloroquine, since the principal indications for chloroquine are for the prophylaxis, suppression, and treatment of malaria, and there is likely to be less long-term use of chloroquine than there is of hydroxychloroquine.

The rate of azithromycin absorption after administration of chloroquine was similar to that of azithromycin administered alone, and the authors reported that chloroquine had no clinically relevant effect on the pharmacokinetics of azithromycin. It is also possible that this increased risk is present in the population represented by CPRD, but that it was not observed in this study due to lack of precision.

The results for cardiovascular mortality in the long term on-treatment analysis appeared inconsistent across the available databases, with increased risk in two US databases but not in CPRD, but overall were increased in the hydroxychloroquine group when a meta-analysis was conducted: pooled hazard ratio (HR) 1.65 (95% confidence interval (CI) 1.12 to 2.44). In terms of the safety data from the study by Lane and colleagues concerning the long-term use of hydroxychloroquine, there is a signal of increased cardiovascular mortality for hydroxychloroquine alone compared with sulfasalazine. For the secondary SCCS, many time-varying covariates including age, season, and other drug exposures were included in conditional Poisson regression models.
