Drugs and the genitourinary system
The GU system consists of the reproductive system (the sex organs) and the urinary system, which includes the kidneys, ureters, bladder, and urethra. The kidneys perform most of the work of the urinary system.
Multitalented
The kidneys perform several vital tasks, including:
- disposing of wastes and excess ions in the form of urine
- filtering blood, which regulates its volume and chemical makeup
- helping to maintain fluid, electrolyte, and acid-base balances
- producing several hormones and enzymes
- converting vitamin D to a more active form
- helping to regulate blood pressure and volume by secreting renin.
Helping hands
Types of drugs used to treat GU disorders include:
- diuretics
- urinary tract antispasmodics
- erectile dysfunction therapy drugs
