Outpatient parenteral antimicrobial therapy (OPAT) offers a safe and effective alternative to hospitalization for serious infections. Advances in antimicrobial agents are expanding treatment options and improving patient convenience and cost-effectiveness.
Area of Science:
- Infectious Diseases
- Pharmacology
- Antimicrobial Stewardship
Background:
- Parenteral antimicrobial therapy for serious infections typically requires hospitalization.
- Outpatient Parenteral Antimicrobial Therapy (OPAT) has emerged as a viable alternative globally over the past 30 years.
- OPAT offers potential benefits in safety, efficacy, patient convenience, and cost-effectiveness.
Purpose of the Study:
- To review recent developments in antimicrobial agents used for OPAT.
- To explore future prospects for antimicrobial agents in the OPAT setting.
- To highlight the expanding scope of infections treatable with OPAT.
Main Methods:
- Review of current literature on antimicrobial agents used in OPAT.
- Analysis of established and emerging antimicrobial drugs for outpatient use.
- Discussion of new developments including broader-spectrum agents and antifungals.
Main Results:
- A variety of infections are amenable to OPAT.
- Established agents like ceftriaxone and teicoplanin, and newer agents like ertapenem and daptomycin are utilized.
- Newer agents with broader activity against resistant organisms and antifungal agents are increasingly used in OPAT.
Conclusions:
- OPAT is a well-established and expanding treatment modality.
- Ongoing development of antimicrobial agents promises to further enhance OPAT efficacy and applicability.
- Future OPAT treatments will likely incorporate novel agents like telavancin, dalbavancin, and omadacycline.

For bacterial pneumonia, antibiotics serve as the cornerstone of therapy. Initial treatment often begins with empirical antibiotics, tailored to the anticipated causative organism and adjusted based on culture results. Key antibiotic choices include:
Drug Delivery: Parenteral Route
There are three primary parenteral routes: intravenous (IV), intramuscular (IM), and subcutaneous (SC). The IV route introduces the drug directly into the bloodstream, ensuring immediate action. The IM route...
