Porcine respiratory disease complex (PRDC) is a major economic problem for swine producers world-wide. Pharmacodynamic, pharmacokinetics and clinical efficacy of florfenicol oral formulations in domestic animals were evaluated. For this purpose the systematic review and meta-analysis were done. In vitro efficacy of florfenicol showed that this drug is highly effective against most important respiratory pathogens. All these facts are shown in our survey. Three studies in pigs were relevant to include in the meta-analysis, which showed that results in the florfenicol group were better than in comparative control groups in all observed parameters: clinical signs, lung lesions and resolution of Actinobacillus pleuropneumoniae (P<0,001). A second meta-analysis with 7 studies showed that the usage of florfenicol reduces mortality in pig herds with PRDC (P<0.05). Other field trials in pigs using florfenicol oral forms where reviewed. After treatment with florfenicol oral solution there was a significant drop of mortality in both groups of pigs (P<0.01); eg. one using florfenicol oral solution in treating PRDC (n=85) and another mixed pneumoenteric infection (n=54). Analysis of data when using premix in pigs (n=118) also suggests that a medicated premix has a favorable anti-infectious effect on pigs, irrespective of the group of animals or the evolution stage of the disease. Finally, favorable effect of florfenicol in treating swine ileitis was also presented. Regarding their pharmacokinetics, in vitro and clinical efficacy of florfenicol oral forms, they should be considered as a powerful tool for combating complex infections that are frequently met in intensive animal production.
