Which Product/Drug Class Segment Dominated the Septicemia Antibiotics Market?
The beta-lactams segment held a dominant position with a share of 31.4% in the market in 2025, due to the widespread availability of beta-lactams and their known therapeutic profiles. Beta-lactams are the oldest known antibiotics for treating a variety of bacterial infections. They are the first-line agents for antibiotic management of critically ill patients with sepsis or septic shock. It has been demonstrated that ICU patients with beta-lactam underexposure have a 1.5-fold higher risk of clinical failure.
Beta-Lactam/Beta-Lactamase Inhibitor Combinations
The beta-lactam/beta-lactamase inhibitor combinations segment is expected to grow at the fastest CAGR of 5.1% in the market during the forecast period. Beta-lactamase (BL) inhibitors, such as clavulanic acid, sulbactam, and tazobactam, are typically prescribed in combination with beta-lactams to prevent the development of antimicrobial resistance. They inhibit the enzyme serine beta-lactamase that inactivates the beta-lactam ring, decreasing the therapeutic potential of beta-lactams.
Why Did the Empiric Therapy Segment Dominate the Septicemia Antibiotics Market?
The empiric therapy segment held the largest revenue share of 72.4% in the market in 2025, due to the need for rapid intervention of sepsis patients. Broad-spectrum antibiotics are ideal for empiric therapy, as they provide coverage of multiple organisms. According to a recent cross-sectional study on 894,724 adults having suspected sepsis, 379,987 received empiric therapy. The most common empiric antibiotics were vancomycin (41.2%), ceftriaxone (37.8%), piperacillin-tazobactam (31.1%), and cefepime (24.8%).
Targeted/Culture-Directed Therapy
The targeted/culture-directed therapy segment is expected to grow with the highest CAGR of 5.0% in the market during the studied years.

The intravenous (IV) segment contributed the biggest revenue share of 72.4% in the market in 2025, due to faster onset of action and maximum bioavailability. The IV route is predominantly preferred for patients with severe sepsis or septic shock. It eliminates the first-pass metabolism pathway and provides the benefit of drug administration even when the patient is unconscious. It delivers the drug directly into the bloodstream, thereby delivering it throughout the body.
Oral
The oral segment is expected to expand rapidly in the market with a CAGR of 5.4% in the coming years. The oral route is the most convenient and affordable, eliminating the need for skilled healthcare professionals for drug delivery. It is preferred by patients of all age groups. Antibiotics are delivered through the oral route in patients with early-stage sepsis.
What Made Community-acquired Sepsis the Dominant Segment in the Septicemia Antibiotics Market?
The community-acquired sepsis segment accounted for the highest revenue share of 56.7% in the market in 2025, due to the higher incidence of community-acquired (CA) sepsis compared to hospital-acquired (HA) sepsis. CA sepsis develops when patients come into close contact with other people who are suffering from infectious diseases. It starts within ≤72 h of hospital admission in an infected patient without recent exposure to healthcare risks.
MDR/XDR Pathogen-Targeted Therapy
The MDR/XDR pathogen-targeted therapy segment is expected to witness the fastest growth with a CAGR of 5.2% in the market over the forecast period. Sepsis caused by XDR pathogens is characterized by high mortality rates. Polyspecific intravenous immunoglobulin (IVIG) is used as an adjunctive therapy for a long time. It is estimated that the prevalence of XDR P. aeruginosa among nosocomial pathogens ranges between 9% and 11.2%.
Which End-User Segment Led the Septicemia Antibiotics Market?
The hospital (ICU) segment led the market with a share of 53.5% in 2025, due to the increasing number of hospital admissions and surgeries. This results from the rising prevalence of chronic disorders and the growing number of accidents. Immunocompromised patients are likely to get affected by hospital-acquired infections (HAIs), leading to sepsis. Hospitals have favorable infrastructure and skilled professionals to cure a patient from sepsis.
Ambulatory Infusion Centers/Outpatient Parenteral Therapy
The ambulatory infusion centers/outpatient parenteral therapy segment is expected to show the fastest growth with a CAGR of 5.3% over the forecast period. Patients with mild or moderate sepsis are not required to be admitted to the hospital. They prefer visiting ambulatory infusion centers or outpatient centers for advanced care. These centers have specialized equipment and the desired therapeutics to treat numerous patients.
How the First-Line Segment Dominated the Septicemia Antibiotics Market?
The first-line segment registered its dominance over the global market with a share of 72.4% in 2025. First-line agents are standard treatment given to the majority of patients with sepsis. The recommended first-line agent for septic shock is norepinephrine, preferably administered through a central catheter. First-line therapy prevents organ failure, stabilizes vital functions, and improves survival rates.
Second/Third-Line
The second/third-line segment is expected to account for the highest growth with a CAGR of 5.2% in the forthcoming years. The increasing cases of antimicrobial resistance necessitate healthcare professionals to provide advanced second/third-line therapy to patients. Second-line therapy is preferred when the first-line treatment fails to control the infection or restore organ function.
Why Did the Hospital Pharmacy/Institutional Procurement Segment Dominate the Septicemia Antibiotics Market?
The hospital pharmacy/institutional procurement segment held a major revenue share of 54.8% in the market in 2025, due to specialized infrastructure for the storage and distribution of antibiotics to patients. Hospital pharmacies comply with stringent regulations required for the Antimicrobial Stewardship Program and other guidelines, providing high-quality drugs to patients. Institutional procurement overcomes challenges related to the supply chain and local sourcing.
