A diuretic (/ ˌ d aɪ j ʊ ˈ r ɛ t ɪ k /) is any substance that promotes diuresis, the increased production of urine. This includes forced diuresis. A diuretic tablet is sometimes colloquially called a water tablet. There are several categories of diuretics. All diuretics increase the excretion of water from the body, through the kidneys ...
The thiazide diuretics also deplete circulating potassium unless combined with a potassium-sparing diuretic or supplemental potassium. Some authors have challenged thiazides as first line treatment. [55] [56] [57] However, as the Merck Manual of Geriatrics notes, "thiazide-type diuretics are especially safe and effective in the elderly." [58]
Acetazolamide, sold under the trade name Diamox among others, is a medication used to treat glaucoma, epilepsy, acute mountain sickness, periodic paralysis, idiopathic intracranial hypertension (raised brain pressure of unclear cause), heart failure and to alkalinize urine.
Osmotic diuresis is the increase of urination rate caused by the presence of certain substances in the proximal tubule (PCT) of the kidneys. [2] The excretion occurs when substances such as glucose enter the kidney tubules and cannot be reabsorbed (due to a pathological state or the normal nature of the substance).

Thiazide diuretics inhibit this receptor, causing the body to release NaCl and water into the lumen, thereby increasing the amount of urine produced each day. [6] An example of a molecule that is chemically a thiazide but not used as a diuretic is methylchloroisothiazolinone , often found as an antimicrobial in cosmetics.
Mercurial diuretics such as mersalyl acid were once in common use, but have been superseded by the thiazides and loop diuretics, which are safer and longer-acting, as well as being orally active. Thiol affinity chromatography
WHODrug concepts can be organized into groups. Standardised Drug Groupings (SDGs) define groups of drugs. For example, diuretics, corticosteroids, drugs used in diabetes. Groups are also defined based on interaction, for example, drugs interacting with CYP2C8 or drugs interacting with UGT. R,Lee [4]
