Abstract:
Acute bacterial rhinosinusitis is a common infection resulting in substantial morbidity. Cefdinir, an oral cephalosporin, has extended-spectrum, bactericidal activity against common acute bacterial rhinosinusitis pathogens, including Streptococcus pneumoniae, Haemophilus influenzae and Moraxella catarrhalis. Cefdinir shows rapid oral absorption and good respiratory tissue penetration, and may be administered once daily. In randomised clinical trials, cefdinir showed efficacy similar to that of other recommended regimens in the treatment of acute bacterial rhinosinusitis, namely amoxicillin/clavulanate and levofloxacin. Cefdinir is well tolerated and has shown a low propensity to suppress the normal commensal flora. Cefdinir oral suspension is rated highly by children in terms of its taste and smell. As the only once-daily beta-lactam currently recommended by acute bacterial rhinosinusitis guidelines (for first-line use in patients with mild acute bacterial rhinosinusitis and no recent antibacterial use), cefdinir offers a convenient and attractive treatment option.
Insights
Cefdinir is an effective once-daily oral antibiotic for acute bacterial rhinosinusitis, showing comparable efficacy to other treatments with good tolerability and convenient dosing.
Area of Science:
- Infectious Diseases
- Pharmacology
- Otolaryngology
Background:
- Acute bacterial rhinosinusitis (ABRS) is a prevalent infection causing significant illness.
- Common pathogens include Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis.
Purpose of the Study:
- To evaluate cefdinir as a treatment option for ABRS.
- To assess its efficacy, tolerability, and convenience compared to other regimens.
Main Methods:
- Randomized clinical trials comparing cefdinir to amoxicillin/clavulanate and levofloxacin.
- Evaluation of clinical efficacy, safety, and patient-reported outcomes.
Main Results:
- Cefdinir demonstrated efficacy similar to comparator treatments.
- It is well-tolerated with minimal impact on normal flora.
- Cefdinir oral suspension is palatable for pediatric patients.
Conclusions:
- Cefdinir is a convenient and effective first-line treatment for mild ABRS, especially when once-daily dosing is desired.
- It offers a favorable option due to its efficacy, tolerability, and dosing schedule.
