Brief Summary

The purpose of this study is to evaluate the non-inferiority of the clinical efficacy of two different drugs in the treatment of patients diagnosed with moderate to severe back pain.

Condition or Disease	Intervention/Treatment	Phase

Arms and Interventions

Arm	Intervention/Treatment
Active Comparator: Naproxen Every 8 hours for 4 days.	Drug: Naproxen; Every 8 hours for 4 days.
Experimental: Ketorolac Tromethamine Every 8 hours for 4 days	Drug: Ketorolac Tromethamine; Every 8 hours for 4 days.

Outcome Measures

Primary Outcome Measures

1. 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

1. 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
