🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works by binding to the 30S ribosomal subunit of susceptible bacteria, blocking the attachment of aminoacyl-tRNA to the messenger RNA-ribosome complex. This prevents the addition of new amino acids to the growing peptide chain, thereby inhibiting protein synthesis. As a result, bacteria cannot produce essential proteins needed for growth and multiplication. This medicine is bacteriostatic, meaning it stops bacterial growth rather than directly killing the bacteria, allowing the body's immune system to eliminate them. It is effective against a wide range of gram-positive and gram-negative bacteria, as well as atypical organisms such as Chlamydia, Mycoplasma, Rickettsia, and spirochetes.

Dosage Information
| Adult Dosage | The usual adult dose of this medicine varies depending on the infection being treated. For most infections, a common regimen is 100 mg every 12 hours on the first day, followed by 100 mg once daily or every 12 hours. For acne, doses may be lower, such as 50-100 mg once daily.

| Elderly Dosage | Elderly patients may be more susceptible to side effects. No specific dose adjustment is generally required, but individualization by a clinician is recommended based on renal and hepatic function. |
| Renal Impairment | No dose adjustment is typically required for renal impairment, as doxycycline is primarily excreted in feces. However, in severe renal failure, monitor closely. |
| Hepatic Impairment | Use with caution in patients with hepatic impairment. Dose adjustment may be necessary. Consult your doctor. |
| Maximum Daily Dose | The maximum recommended daily dose is 200 mg for most indications, but may be higher for certain severe infections as determined by a clinician. |
