There are several categories of diuretics. All diuretics increase the excretion of water from the body, through the kidneys. There exist several classes of diuretic, and each works in a distinct way. Alternatively, an antidiuretic, such as vasopressin (antidiuretic hormone), is an agent or drug which reduces the excretion of water in urine.
An osmotic diuretic is a type of diuretic that inhibits reabsorption of water and sodium (Na). They are pharmacologically inert substances that are given intravenously. They increase the osmolarity of blood and renal filtrate. [1] This fluid eventually becomes urine. Two examples are mannitol [2] and isosorbide.
Its effects are opposite that of a diuretic. The major endogenous antidiuretics are antidiuretic hormone (ADH; also called vasopressin) and oxytocin . Both of those are also used exogenously as medications in people whose bodies need extra help with fluid balance via suppression of diuresis.
Loop diuretics usually have a ceiling effect whereby doses greater than a certain maximum amount will not increase the clinical effect of the drug. Also, there is a threshold minimum concentration of loop diuretics that needs to be achieved at the thick ascending limb to enable the onset of abrupt diuresis. [10]
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.
Antiuricosuric drugs raise serum uric acid levels and lower urine uric acid levels. These drugs include all diuretics, pyrazinoate, pyrazinamide, ethambutol, niacin, and aspirin. [5] The NSAID diclofenac has an antiuricosuric action, which may be partly responsible for the extraordinary toxicity of this drug in vultures. [6]

These medications are available for purchase only with a physician’s prescription. They include, but are not limited to, drugs that target hypertension (antihypertensives), hyperlipidemia (antihyperlipidemics) and blood clotting (blood-thinners) to reduce the risk of cardiovascular diseases.
