From the Research
Roxithromycin is a macrolide antibiotic used to treat various bacterial infections, particularly those affecting the respiratory tract, skin, and soft tissues, with a typical adult dosage of 150 mg twice daily or 300 mg once daily for 5-10 days, depending on the infection being treated. The medication works by inhibiting bacterial protein synthesis, preventing bacteria from growing and multiplying 1.
Key Points to Consider
- Roxithromycin has been shown to be effective in treating upper and lower respiratory infections, skin and soft tissue infections, urogenital infections, and orodental infections, with an overall incidence of adverse events of approximately 4% 1.
- The medication should be taken at least 15 minutes before meals or 2 hours after meals for optimal absorption.
- Common side effects include nausea, vomiting, abdominal pain, and diarrhea.
- Roxithromycin may interact with certain medications like statins, warfarin, and ergot alkaloids, potentially causing serious adverse effects.
- Patients with liver disease may require dose adjustments.
- It is essential to complete the full course of treatment even if symptoms improve before the medication is finished to prevent antibiotic resistance and ensure the infection is completely cleared.
Clinical Efficacy and Safety
The clinical efficacy of roxithromycin has been confirmed in various studies, including a study published in 1994, which showed that the medication was effective in treating respiratory tract infections, skin and soft tissue infections, and urogenital infections 1. Another study published in 1989 found that roxithromycin was well tolerated and had less potential than erythromycin to produce clinically significant drug interactions 2.
Comparison with Other Macrolides
Roxithromycin has been compared to other macrolides, such as azithromycin and clarithromycin, in terms of its pharmacokinetic profile, antimicrobial activity, and clinical efficacy. A study published in 1993 found that azithromycin and clarithromycin had distinct advantages over erythromycin, including an improved pharmacokinetic profile and less toxicity 3. However, roxithromycin has been shown to be an attractive therapeutic alternative in its established indications, especially when the option of once-daily administration is considered 1.
