Effectiveness Comparison Between the Drugs TOBRACORT® and TOBRADEX® in Reducing the Signs and Symptoms of Acute Bacterial Conjunctivitis

• Evaluation of signs and symptoms during treatment, with a record of individual scores for each parameter established. [ Time Frame: 7 days of treatment. ] [ Designated as safety issue: No ]
  There will be a total of three returns after inclusion (0 day), and they are 1, 3 and 7 days after initiation of treatment.At the returns of 1 and 3 days, there will be a tolerance of +1 day, and the return of seven days, the tolerance will be ± 1 days. On each return, will be collected data on the efficacy and safety as defined in this protocol.
• Statistical comparison of drug safety, by recording qualitative and quantitative parameters related to adverse effects occurring during treatment. [ Time Frame: 7 days of treatment. ] [ Designated as safety issue: No ]

The primary objective of this study is to evaluate, through clinical parameters, the comparative efficacy between topical Tobracort ® (tobramycin 0.3% dexamethasone + 1% - Chemistry Lab Union) and TOBRADEX ® (tobramycin 0.3% dexamethasone + 1 % - Alcon Lab), using the percentage of improvement (sustained response rate) at the end of treatment.
