Lornoxicam versus diclofenac sodium in acute renal colic: a prospective randomized trial

Background: Acute renal colic is excruciatingly painful event, opioid analgesics and nonsteroidal anti-inflammatory drugs remain the mainstay of treatment for acute renal colic. This study compares diclofenac and lornoxicam in their efficacy to relieve pain of renal origin.Methods: Prospective, randomized, double blind clinical study including eighty patients with renal pain admitted in emergency department of a tertiary care teaching hospital. Parameters were observed at baseline and after 15, 30, 60, 180 minutes and 5hrs of drug treatment. The efficacy of the drug was measured by observing: Pain score, onset & duration of action, rescue drug use, global patient and physician impression.Results: Both drugs are effective in relieving pain of renal origin (p<0.05) and maintaining it over time as well. When decrease in value of pain score compared between two groups at various interval there was statistically significant (p<0.05) decrease in pain score only at 15 minutes in lornoxicam group showing this slightly more effective in early phase compared to diclofenac. In either group there is no statistically significant difference regarding onset of action, duration of action and side effect profile.Conclusions: Both the drugs are equally effective and safe in renal colicky pain with added advantage of lornoxicam being more effective in early period
