🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works by binding to the 50S ribosomal subunit of susceptible bacteria, specifically to the 23S rRNA component. This binding inhibits the translocation step of protein synthesis, preventing the addition of new amino acids to the growing peptide chain. As a result, bacterial protein production is halted, which stops bacterial growth and multiplication. This medicine is typically bacteriostatic, but it can be bactericidal at higher concentrations against certain organisms. It is effective against a wide range of gram-positive and gram-negative bacteria, as well as atypical pathogens such as Mycoplasma, Chlamydia, and Legionella.
Mechanism Steps
💡 How to Take nazolex tablet
Strength: Immediate-release tablet; available in 250 mg and 500 mg strengths.
Dosage Information
| Adult Dosage | The dose of this medicine depends on the type and severity of the infection. For many respiratory tract infections, a common regimen is 500 mg on the first day, followed by 250 mg once daily on days 2 to 5. For uncomplicated chlamydial urethritis or cervicitis, a single 1 g dose is often used. For skin infections, a 5-day course may be prescribed. Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function. |
| Pediatric Dosage | Pediatric dosing is based on weight and the specific infection. It is not established from available information for all indications. Consult a pediatrician for appropriate dosing. |
| Elderly Dosage | Elderly patients may be more sensitive to the side effects of this medicine, especially QT prolongation and liver effects. No specific dose adjustment is usually required, but caution is advised. Dose must be individualized by a qualified clinician. |
| Renal Impairment | No dose adjustment is generally required for mild to moderate renal impairment (GFR 10-80 mL/min). In severe renal impairment (GFR <10 mL/min), use with caution as the pharmacokinetics have not been fully studied. Dose must be individualized by a qualified clinician. |
| Hepatic Impairment | Use with caution in patients with hepatic impairment. No specific dose adjustment is established, but monitoring for liver toxicity is recommended. Dose must be individualized by a qualified clinician. |
| Maximum Daily Dose | The maximum recommended total dose for a course is 1.5 g (e.g., 500 mg on day 1, then 250 mg daily for 4 days). For single-dose therapy, the maximum is 1 g. Do not exceed the prescribed dose. |
