Systemic Methylprednisolone in Chronic Rhinosinusitis

Patients enrolled in the study were given either oral amoxicillin/clavulanate (AMX/C) or metylprednisolone (MP) (group MP) or AMX/C and placebo (group P) twice daily using a random allocation chart based on a table of random numbers. Oral AMX/C was administered 45/6.4 mg/kg/d (maximum 2000/285 mg/d) for 30 days for both groups. Oral MP was administered for the first 15 days: 1 mg/kg/d (maximum 40 mg/d) for 10 days, 0.75 mg/kg/d for 2 days, 0.5 mg/kg/d for 2 days, and 0.25 mg/kg/d for 1 day. Placebo tablets contained lactose and were of same size and color as MP tablets.
