Failure of effervescent
zinc acetate lozenges to alter the course of upper respiratory tract infection in Australian adults
Neither zinc gluconate nor
zinc acetate lozenges affected the duration or severity of cold symptoms in 281 subjects with natural (not experimentally induced) colds in another trial [68].
However, treatment with
zinc acetate lozenges (providing 5 or 11.5 mg zinc) had no effect on either cold duration or severity.
Another randomized, double - blind placebo study found that those who took
zinc acetate lozenges had a significantly shorter duration of a cold compared to those who took a placebo.
In a randomized, double - blind, placebo - controlled clinical trial, 50 subjects (within 24 hours of developing the common cold) took
a zinc acetate lozenge (13.3 mg zinc) or placebo every 2 — 3 wakeful hours.
