Important Summary For one mark Question
1) Diuretic drugs promote urine output. They act directly on the kidneys and increase the excretion of water and ions (Na+, Cl−, or ï€ 3 HCO ) from the body.
2) High efficacy diuretics exhibit their effects by acting on the ascending limb of the loop of Henle, therefore also known as loop diuretics.
3) The most commonly used loop diuretic is furosemide.
4) The most commonly used thiazide is chlorothiazide
5) Absorption of thiazides is fast, when they are administered orally.
6) Osmotic diuretics are named so as they utilise their osmotic action to draw water from the tissues.
7) Anti-diuretic drugs decrease the volume of urine by suppressing urine formation. These drugs are primarily indicated for patients with diabetes insip idus.
8) Antidiuretic Hormone (ADH) is a non -peptide hormone. It is secreted by the neurohypophysis part of posterior pituitary.
9) The most significant use of amiloride is the management of lithium-induced nephrogenic diabetes insipidus.
10) Contraindications to the use of thiazide diuretics as anti -diuretic agents include hyperkalaemia and renal failure.
