DESCRIPTION
Spironolactone is a potassium-sparing diuretic, which works by antagonising the effects of aldosterone.
PHARMACODYNAMICS
Originally spironolactone was only studied for its potassium sparing diuretic effect.[A11837] Spironolactone competitively inhibits mineralocorticoid receptors in the distal convoluted tubule to promote sodium and water excretion and potassium retention.[A11837]. Inhibition of this receptor leads to increased renin and aldosterone levels.[A11837]; ; Spironolactone is structurally similar to progesterone and as a result is associated with progestogenic and antiandrogenic effects.[A11837]
MOA
Spironolactone competitively inhibits aldosterone dependant sodium potassium exchange channels in the distal convoluted tubule.[Label] This action leads to increased sodium and water excretion, but more potassium retention.[Label] The increased excretion of water leads to diuretic and also antihypertensive effects.[Label]
ROE
Metabolites of spironolactone are excreted 42-56% in urine, and 14.2-14.6% in the feces.[A178165] No unmetabolized spironolactone is present in the urine.[A178165]
TOXICITY
Patients experiencing an overdose may present with drowsiness, mental confusion, maculopapular or erythematous rash, nausea, vomiting, dizziness, or diarrhea. Vomiting is generally induced or a gastric lavage is performed.[Label] Supportive treatment involves maintining hydration, electrolyte balance, and vital functions[Label].; ; The oral LD50 in mice, rats, and rabbits is >1g/kg.[Label]; ; Spironolactone should be avoided in pregnancy due to reports of feminization of male fetuses in animal studies.[Label] Active metabolites of spironolactone are present in breast milk and levels that are likely inconsequential, though the long term effects have not been studied.[Label]; ; In animal studies, spironolactone slowed follicle development, ovulation, and implantation.[Label] Spironolactone increased the incidence of benign adenomas in the testes of male rats, benign uterine endometrial stromal polyps in female rats, and thyroid follicular cell adenomas in both sexes of rats.[Label] Spironolactone and canrenone are generally not considered to be mutagenic in tests but canrenone occasionally tests positive for mutagenicity with metabolic activation and spironolactone has occasionally tested inconclusive though slightly positive for mutagenicity.[Label]
METABOLISM
Spironolactone is deacetylated to 7α-thiospironolactone.[A178069,A178072] 7α-thiospironolactone is S-methylated to 7α-thiomethylspironolactone or undergoes an elimination reaction to canrenone.[A178069,A178072] 7α-thiomethylspironolactone is reduced to 3α-hydroxythiomethylspironolactone or 3β-hydroxythiomethylspironolactone.[A178069,A178072]; ; Canrenone was originally thought to be the primary circulating metabolite, however more recent studies have demonstrated that the primary metabolite is actually 7α-thiomethylspironolactone.[A11837,A178207]
ABSORPTION
Spironolactone reaches a maximum concentration in 2.6 hours and an active metabolite (canrenone) reaches a maximum concentration in 4.3 hours.[Label] When taken with food, the bioavailability of spironolactone increases to 95.4%.[Label]; ; Giving spironolactone with food increases the maximum concentration from 209ng/mL to 301ng/mL.[A178165] The time to maximum concentration also increases from 2.28 hours to 3.05 hours.[A178165] The area under the curve varies from 2103ng/mL\*hr to 4544ng/mL*hr.[A178165]
HALF-LIFE
1.4 hours.[Label,A178192]; ; Canrenone has a half life of 16.5 hours, 7-α-thiomethylspirolactone has a half life of 13.8 hours, and 6-Ã-hydroxy-7-α-thiomethylspirolactone has a half life of 15 hours.[Label,A178192]
DESCRIPTION
Spironolactone is an orally active, potassium-sparing diuretic, which works by antagonising the effects of aldosterone at renal mineralocorticoid receptors.

INDICATION
Spironolactone is indicated for the treatment of New York Heart Association Class III-IV heart failure, management of edema in cirrhotic adults not responsive to fluid and sodium restrictions, primary hyperaldosteronism short-term preoperatively, primary hyperaldosteronism long-term in patients with aldosterone producing adrenal adenomas that are not candidates for surgery or patients with bilarteral micro/macronodular adrenal hyperplasia, as an add-on therapy in hypertension, and in nephrotic syndrome when treatment of the disease as well as fluid and sodium restriction with other diuretics is inadequate.[Label]; ; Spironolactone has antiandrogenic activity which leads to many of its off label uses. Spironolactone is used off label in the treatment of hirsutism, female pattern hair loss, and adult acne vulgaris.[A178135]; ; Spironolactone is also frequently used for its antiandrogenic effects in transgender female patients due to its low cost and reducing male-pattern hair growth.[A178138]
PRICE
29
DESCRIPTION
Spironolactone is an aldosterone antagonist that acts on the aldosterone mineralocorticoid receptor (IC50=24 nM) and androgen receptor (IC50=77 nM), promotes podocyte autophagy and regulates pain. Spironolactone improves hypertension-related vascular hypertrophy and remodeling by reducing angiotensin II (Ang II)-induced inflammation, reduces aldosterone-induced vascular and soft tissue calcification through PIT1-dependent signaling, and alleviates vascular dysfunction in type II diabetic mice by reducing oxidative stress and restoring NO/GC signaling; at low concentrations, it and its metabolites can interfere with aldosterone biosynthesis in the adrenal cortex and inhibit voltage-dependent Ca2+ channels to exert antihypertensive effects[1][2][3][4][5][6][7][8][9][10].
