Abstract:
Although ofloxacin-ornidazole fixed-dose combination (FDC) is a rampantly used antibiotic combination for mixed-infection diarrhea in India, the adverse drug reaction (ADR) associated with these FDCs remains underreported. Herein, the authors present a case report of a definitive ofloxacin-ornidazole FDC-induced pancreatitis. The nonalcoholic adult male patient showed a sharp piercing epigastric pain flowing to the back, gradually rising in severity, which started after taking ofloxacin-ornidazole FDC tablet over the counter. Serum lipase concentration measured in the emergency room was 635 units per liter (normal range- 13-60 units/L) and serum amylase was 377 units/L (normal range- 30-110 units/L). Ultrasonography and an axial computed tomography of the abdomen confirmed the diagnosis of acute pancreatitis. Ofloxacin-ornidazole FDC tablet was stopped immediately. Past treatment records confirmed accidental rechallenge. In conclusion, this is a first case report of ofloxacin-ornidazole FDC-induced pancreatitis.
Insights
This case report details a patient who developed acute pancreatitis after taking ofloxacin-ornidazole fixed-dose combination (FDC) antibiotics. This adverse drug reaction highlights the underreporting of pancreatitis linked to this common diarrhea medication.
Area of Science:
- Gastroenterology
- Pharmacology
- Internal Medicine
Background:
- Ofloxacin-ornidazole fixed-dose combination (FDC) is widely prescribed in India for mixed-infection diarrhea.
- Adverse drug reactions (ADRs) associated with these FDCs are frequently underreported.

Acute Pancreatitis I: Introduction
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:
Drugs for Treatment of Diarrhea-Predominant IBS
Two specific drugs used in the treatment are alosetron (Lotronex) and eluxadoline (Viberzi). Alosetron, a 5-HT3 antagonist, works by slowing the movement of stools in the gut, reducing bowel...
