Treatment of Pseudomonas aeruginosa infections in the lungs of cystic fibrosis patients aged 6 years and older, helping to control chronic respiratory infections and improve lung function.
As an aminoglycoside antibiotic, tobramycin inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, effectively killing susceptible Pseudomonas bacteria when delivered directly to the airways.
Bethkis is administered twice daily via nebulizer using a compatible device. Patients should complete the full treatment cycle as prescribed. Common side effects may include voice changes, sore throat, and cough. Hearing and kidney function monitoring may be recommended during treatment.
