Drugs Used to Treat Disorders of the Urinary System

These flashcards cover key concepts from the lecture on drugs for urinary system disorders.

Urinary Tract Infections (UTIs)

The second most common cause of death from infection, affecting eleven million people treated annually.

Gram-negative aerobic bacilli

Bacteria commonly responsible for UTIs, especially Escherichia coli.

Indwelling urinary catheter

A catheter that remains in place for continuous drainage; associated with increased risk of nosocomial infections.

Cystoscopy

A diagnostic procedure used to examine the bladder and urethra.

Fosfomycin

An antibiotic used for single-dose treatment of UTIs, inhibiting bacterial cell wall synthesis.

Nitrofurantoin

An antibiotic that interferes with several bacterial enzyme systems, used to treat UTIs.

Overactive Bladder Syndrome

A condition characterized by urgency, frequency, and nocturia, often affecting adults over 65.

Anticholinergic Agents

Drugs that block cholinergic receptors in the bladder, reducing urgency and frequency of contractions.

Mirabegron

A beta-3 adrenergic agent that relaxes the detrusor muscle, increasing bladder capacity for OAB treatment.

Phenazopyridine

A urinary agent that produces a local anesthetic effect, relieving pain and urgency associated with UTIs.
