🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works by binding to the 50S ribosomal subunit of susceptible bacteria. This binding blocks the translocation step of protein synthesis, preventing the bacteria from making essential proteins needed for growth and multiplication. As a result, the bacteria stop growing and are eventually cleared by the body's immune system. This medicine is bacteriostatic at usual doses but can be bactericidal at higher concentrations against certain organisms.
Mechanism Steps
💡 How to Take Rzit 500mg Tablet
Strength: Tablet, 500 mg
Dosage Information
| Adult Dosage | The usual adult dose for many infections is 500 mg once daily for 3 to 5 days, or a single 1 g dose for certain infections such as uncomplicated chlamydial urethritis. For community-acquired pneumonia, a common regimen is 500 mg on day 1 followed by 250 mg once daily on days 2 to 5. Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function. |
| Pediatric Dosage | Pediatric dosing is not established from available information. Consult a pediatrician. |
| Elderly Dosage | Elderly patients may be more susceptible to side effects such as heart rhythm changes and hearing problems. No specific dose adjustment is usually required, but use with caution and monitor closely. |
| Renal Impairment | No dose adjustment is generally needed for mild to moderate renal impairment. In severe renal impairment (creatinine clearance less than 10 mL/min), use with caution as experience is limited. |
| Hepatic Impairment | No specific dose adjustment is recommended for mild to moderate hepatic impairment. In severe hepatic impairment, use with caution and monitor liver function. |
| Maximum Daily Dose | The maximum recommended total dose is 1 g per day for a single-day regimen, or 500 mg per day for multi-day regimens. Do not exceed the prescribed dose. |
