Applications of 67-20-9
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Antibacterial agent for treating lower urinary tract infections (e.g., acute cystitis, acute exacerbations of chronic cystitis) caused by susceptible bacteria | Administered orally; absorbed via the gastrointestinal tract and concentrated in urine, where it inhibits bacterial DNA, RNA, and protein synthesis by interfering with enzymatic systems (e.g., acetyl-CoA, nitroreductase); requires acidic urine for optimal activity—often co-administered with vitamin C to acidify urine |
| Pharmaceuticals | Long-term, low-dose maintenance therapy to prevent recurrent urinary tract infections | Single oral dose of 50–100 mg administered at bedtime daily, leveraging sustained urinary antibacterial concentrations for prophylaxis while minimizing rapid resistance development |
| Pharmaceuticals | Adjunctive treatment of bacterial cystitis in companion animals (e.g., dogs, cats) in veterinary clinical practice | Dosed according to body weight (typically 2–5 mg/kg, administered two to four times daily); renal function must be closely monitored due to interspecies metabolic differences that increase risk of toxic accumulation |
