What Are Ofloxacin and Ornidazole Tablets IP?
Ofloxacin and Ornidazole Tablets IP is a fixed-dose combination (FDC) antibiotic that packs two powerful antimicrobial agents into a single tablet. It is classified under the Indian Pharmacopoeia (IP) standard, which means it meets the regulatory quality requirements set by the Government of India.
- Ofloxacin belongs to the fluoroquinolone class of antibiotics. It works against a broad spectrum of gram-positive and gram-negative bacteria.
- Ornidazole belongs to the nitroimidazole group. It is highly effective against anaerobic bacteria and protozoa — organisms that thrive in low-oxygen environments like the gut.
Together, they form a synergistic antimicrobial pair that is particularly powerful against mixed infections, where both bacteria and parasites are involved simultaneously.

Ofloxacin and Ornidazole Tablets IP: Uses, Benefits & How They Work
How They Work
The dual mechanism of action is what makes this combination so clinically valuable:
- Ofloxacin inhibits the bacterial DNA gyrase enzyme — a protein that is essential for DNA replication and repair in bacteria. By blocking this enzyme, Ofloxacin halts bacterial cell division and eventually leads to bacterial death.
- Ornidazole enters the cells of anaerobic bacteria and protozoa, where it generates toxic metabolites that damage DNA and prevent replication, leading to cell death.
This two-pronged attack ensures comprehensive coverage across a wider range of pathogens than either drug could achieve alone.
Common Uses
| Infection Type | Examples |
| Gastrointestinal infections | Diarrhoea, dysentery, mixed intestinal infections |
| Urinary tract infections (UTIs) | Bacterial UTIs in adults |
| Respiratory tract infections | Bacterial pneumonia, bronchitis |
| Gynaecological infections | Vaginal infections, post-surgical infections |
| Skin & soft tissue infections | Infected wounds, cellulitis |
| Protozoal infections | Amoebiasis, trichomoniasis, giardiasis |
| Intra-abdominal infections | Peritonitis, post-operative infections |
| Eye & ear infections | Bacterial conjunctivitis, external ear infections |
Key Benefits
- Broad-spectrum coverage with a single tablet
- Effective against both aerobic and anaerobic organisms
- Clinically proven to reduce symptoms faster in mixed infections
- Widely available across pharmacies in India at affordable prices
- Manufactured by top-tier WHO-GMP and ISO-certified companies
Possible Side Effects
While generally well-tolerated, some patients may experience nausea, vomiting, abdominal discomfort, headache, dizziness, or a metallic taste in the mouth. Most side effects resolve on their own. Consult a doctor if symptoms worsen or persist.
