Randomized Controlled Trial Multicenter StudyA randomized, double-blind, parallel-group, multicenter, placebo-controlled study of the safety and efficacy of extended-release guaifenesin/pseudoephedrine hydrochloride for symptom relief as an adjunctive therapy to antibiotic treatment of acute respiratory infections.
This study assessed the efficacy and safety of guaifenesin 600 mg and pseudoephedrine hydrochloride 60 mg extended-release bilayer tablets in providing relief of acute respiratory symptoms when used as an adjunct to antibiotics in patients with an acute respiratory infection (ARI). ⋯ As adjunctive therapy for symptom relief for patients taking antibiotics for ARIs, guaifenesin/pseudoephedrine shortened time to relief and improved bothersome respiratory symptoms better than placebo, with greatest effects seen for nasal congestion and sinus headache.
