Antibiotic Stewardship: Why Combination Therapy Matters in Hospital Care

Antimicrobial resistance (AMR) is one of the most pressing public-health challenges of our time. The World Health Organization considers AMR a top global threat, and India is among the countries facing a significant burden of resistant infections.

Antibiotic stewardship refers to a coordinated set of strategies that promote the appropriate use of antibiotics in order to improve patient outcomes, reduce resistance and decrease the spread of resistant infections.

• Use antibiotics only when clearly indicated
• Choose the right drug, dose and duration based on culture and clinical context
• De-escalate or switch to a narrower-spectrum agent when sensitivities are available
• Avoid unnecessary IV therapy when oral options are equally effective
• Educate prescribers, pharmacists, nurses and patients on responsible antibiotic use

Many Gram-negative and Gram-positive bacteria produce enzymes called beta-lactamases that break down beta-lactam antibiotics (penicillins and cephalosporins), rendering them ineffective.

Beta-lactamase production is one of the most common mechanisms of resistance encountered in hospital infections, especially in urinary, abdominal and respiratory infections.

Combining a beta-lactam antibiotic with a beta-lactamase inhibitor preserves and extends the antibiotic's activity.

• The beta-lactam antibiotic (e.g., ceftriaxone) acts on the bacterial cell wall
• The beta-lactamase inhibitor (e.g., tazobactam) protects the antibiotic from being broken down by bacterial enzymes
• Together, the combination is effective against many beta-lactamase producing organisms

A doctor may consider a ceftriaxone-tazobactam combination injection for:

• Complicated urinary tract infections
• Lower respiratory tract infections including hospital-acquired pneumonia
• Intra-abdominal infections, including peritonitis
• Skin and soft-tissue infections, including diabetic foot infections
• Gynaecological infections such as pelvic inflammatory disease
• Septicaemia and bacteraemia

Selection should always be based on local antibiograms and culture sensitivity wherever possible.

Effective stewardship is supported by a reliable supply chain of quality-assured antibiotics. Hospitals and chemists depend on transparent sourcing and consistent availability of injectables for empirical and targeted therapy.

Pharmaceutical marketing and distribution partners play a key role by ensuring uninterrupted availability of essential combination injections through authorised stockists, distributors and hospital pharmacies.

• Antibiotics are not effective against viral infections such as the common cold or flu
• Always complete the prescribed antibiotic course, even if you feel better
• Never share or self-medicate with leftover antibiotics
• Report side effects promptly to your doctor

• Antibiotic resistance is a serious and growing problem
• Stewardship programmes protect both patients and antibiotics
• Beta-lactam + beta-lactamase inhibitor combinations are valuable tools when used appropriately
• Quality manufacturing and reliable supply chains are integral to responsible antibiotic use
