Pidotimod activity against chronic bronchitis exacerbations.
The efficacy of pidotimod ((R)-3-[(S)-(5-oxo-2-pyrrolidinyl) carbonyl]-thiazolidine-4-carboxylic acid, PGT/1A, CAS 121808-62-6) in the management of infectious exacerbations of chronic bronchitis was evaluated in a double-blind, placebo-controlled study in parallel groups over 5 months (60 days of treatment and 90 days of follow-up). The study enrolled 580 patients, of whom 514 could be evaluated. The pidotimod group had fewer and shorter infectious episodes, fewer days of antibiotic therapy and fewer days unable to undertake normal activities. The difference vs. placebo was significant during the follow-up period and, in those subjects with a less severe history, during the treatment period also. Pidotimod was well tolerated.
