The mean ages were 7.6\u00a0years (SD\u2009\u00b1\u20093.2\u00a0years) and 42.8\u00a0years (SD\u2009\u00b1\u200916.1) and the proportion of female patients were 51% and 65%, respectively. The duration of treatment in pediatric patients was &lt;\u20095\u00a0days in 2% of patients, 5\u00a0days in 13.7%, 6\u20137\u00a0days, in 82.4% and &gt;\u20097\u00a0days in 2% while in adults patients it was &lt;\u20095\u00a0days in 17%, 5\u00a0days in 69.2%; 6\u20137\u00a0days in 28.8% of patients. Adverse events (AEs) were registered in 9.6% and 19.2% of pediatric and adult patients, respectively. These AEs had definite relation of causality with the study drugs in 2 adults (20% of AEs) and possible causality with the study drugs in 4 pediatric (80% of AEs) and 2 adult cases (20% of AEs). Our results provide valuable data to develop trials of pharmacovigilance where different statistical parameters should be considered to calculate an adequate sample size in studies evaluating STG in pediatric or adult patients.<\/jats:p>\n                <jats:p><jats:italic>Trial registration<\/jats:italic> NCT02879981 and NCT02902640<\/jats:p>\n              <\/jats:sec>","DOI":"10.1186\/s13104-019-4150-2","type":"journal-article","created":{"date-parts":[[2019,3,4]],"date-time":"2019-03-04T13:03:35Z","timestamp":1551704615000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["A pilot study of safety of sulfamethoxazole, trimethoprim and guaifenesin in pediatric and adult patients with acute bronchitis"],"prefix":"10.1186","volume":"12","clinical-trial-number":[{"clinical-trial-number":"nct02879981","registry":"10.18810\/clinical-trials-gov"},{"clinical-trial-number":"nct02902640","registry":"10.18810\/clinical-trials-gov"}],"author":[{"given":"Mayer","family":"Falcon","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carlos","family":"Iberico","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Frances","family":"Guerra","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Isabel","family":"Reyes","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Efra\u00edn","family":"Felix","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M\u00f3nica","family":"Flores","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jorge","family":"de los R\u00edos","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maria E.","family":"Diaz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alberto","family":"Casas","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sergio","family":"Sanchez-Gambetta","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Roberto","family":"Carrasco","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2019,3,4]]},"reference":[{"key":"4150_CR1","first-page":"1508","volume":"12","author":"P Wark","year":"2015","unstructured":"Wark P.
