Which medication is commonly prescribed for a client diagnosed with a urinary tract infection?

Ciprofloxacin is an antibiotic that belongs to the fluoroquinolone class and is commonly prescribed for urinary tract infections (UTIs). It works by inhibiting bacterial DNA gyrase, an essential enzyme for bacterial replication and repair, effectively stopping the growth of the bacteria causing the infection.

This medication is often chosen for UTIs due to its broad spectrum of activity against a variety of pathogens, including those commonly responsible for urinary infections. It is particularly effective for treating both complicated and uncomplicated UTIs. In contrast, the other medications listed serve different therapeutic purposes: Anastrozole is used primarily in the treatment of breast cancer, Levothyroxine is a thyroid hormone replacement for hypothyroidism, and Metformin is an oral antidiabetic agent used to manage type 2 diabetes. Therefore, Ciprofloxacin stands out as the appropriate choice for addressing a urinary tract infection.
