Study Notes
Diuretic Drugs Overview
- Diuretic drugs increase urine output by acting on the kidneys.
- They promote the excretion of water and ions, specifically sodium (Na), chloride (Cl), and bicarbonates (HCO3).
- Key renal processes involved in urine formation include glomerular filtration, tubular reabsorption, and tubular secretion.
Mechanism of Action
- Diuretics primarily function by decreasing tubular reabsorption, which enhances glomerular filtration.
- They do not influence the glomerular filtration rate (GFR) or the effects of Anti-Diuretic Hormone (ADH) in the nephron's distal portion.
Therapeutic Uses
- Effective in treating cardiac oedema, particularly related to congestive heart failure.
- Also used for conditions like nephrotic syndrome, diabetes insipidus, hypertension, nutritional oedema, oedema of pregnancy, and liver cirrhosis.
- Diuretics help reduce intracellular pressure and cerebrospinal fluid pressure.
Classification of Diuretics
-
Carbonic Anhydrase Inhibitors:
- Examples include Acetazolamide, Methazolamide, and Dichlorphenamide.
-
Thiazide Derivatives:
- Chlorothiazide and its analogues are key examples in this category.
