简要总结
The primary objective is to evaluate the safety and efficacy of Phenazopyridine HCl Tablets, USP 200 mg as a short term analgesic treatment of pain upon urination associated with Uncomplicated Urinary Tract Infections (uUTI).
The secondary exploratory objective is to evaluate safety and efficacy of Phenazopyridine HCl Tablets, USP 200 mg as a short term analgesic treatment of burning upon urination associated with uUTI.
详细描述
Subjects will make separate self-assessments for severity of pain and burning upon urination using the NRS and self-assessments of their discomfort using the GSAS at designated intervals for 24 hours. Subjects will rate the effectiveness of the study medication using the SASMS at a designated interval for 24 hours.
