Arm && Interventions

Group	Intervention	Description
Ketorolac Tromethamine	Ketorolac Tromethamine	Every 8 hours for 4 days
Naproxen	Naproxen	Every 8 hours for 4 days.

Primary Outcome Measures

Name	Time	Method
Efficacy of treatment in back pain relief based on Visual Analog Scale (VAS).	4 days	The individual response rate to the relieve of pain is calculated by measuring VAS during the first and last visit.; The response rate is calculated using the following formula: Response rate = (VASvi - VASvf) / VASvi; Considering: * VASvi: VAS in the first visit; * VASvf: VAS at the last visit;

Secondary Outcome Measures

Name	Time	Method
Safety will be evaluated by the adverse events occurrences	day 4	Adverse events will be collected and followed in order to evaluate safety and tolerability
