🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works by binding to the 50S ribosomal subunit of susceptible bacteria, thereby inhibiting protein synthesis. This action is primarily bacteriostatic, but it can be bactericidal at higher concentrations. By blocking the production of essential proteins, it prevents bacterial growth and multiplication, allowing the body's immune system to eliminate the infection.

Dosage Information
| Adult Dosage | The usual adult dose of this medicine is 250 mg to 500 mg every 6 to 12 hours, depending on the type and severity of the infection. For severe infections, doses up to 4 grams per day may be used. The dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function. Always follow your doctor's prescription exactly. |
| Pediatric Dosage | Pediatric dosing is not established from available information. Consult a pediatrician for appropriate dosing based on the child's age, weight, and condition. |
| Elderly Dosage | Elderly patients may be more susceptible to side effects, especially hearing loss and cardiac arrhythmias. Dose adjustment may be necessary based on renal and hepatic function. Use with caution and monitor closely. |
| Renal Impairment | Erythromycin is primarily excreted in bile, so dose adjustment is usually not required in renal impairment. However, in severe renal impairment, caution is advised and monitoring for side effects is recommended. |
| Hepatic Impairment | In patients with severe hepatic impairment, erythromycin should be used with caution. Dose reduction may be necessary. Monitor liver function tests regularly. |
