Identification

Name
Spironolactone
Accession Number
DB00421
Description

Spironolactone is a potassium sparing diuretic like eplerenone that competitively inhibits mineralocorticoid receptors in the distal convoluted tubule to promote sodium and water excretion and potassium retention.8. Spironolactone was originally developed purely for this ability before other pharmacodynamic properties of the drug were discovered.8,11 It is indicated to treat a number of conditions including heart failure, deem, hyperaldosteronism, adrenal hyperplasia, hypertension, and nephrotic syndrome.Label Off label uses of spironolactone involving its antiandrogenic activity include hirsutism, female pattern hair loss, and adult acne vulgaris.4 Spironolactone is also frequently used in medical gender transition.5

Spironolactone was developed in 1957, marketed in 1959, and approved by the FDA on January 21, 1960.10,12

Pharmacology

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.4

Spironolactone is also frequently used for its antiandrogenic effects in transgender female patients due to its low cost and reducing male-pattern hair growth.5

Pharmacodynamics

Originally spironolactone was only studied for its potassium sparing diuretic effect.8 Spironolactone competitively inhibits mineralocorticoid receptors in the distal convoluted tubule to promote sodium and water excretion and potassium retention.8. Inhibition of this receptor leads to increased renin and aldosterone levels.8

Spironolactone is structurally similar to progesterone and as a result is associated with progestogenic and antiandrogenic effects.8

Mechanism of action

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

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.6 The time to maximum concentration also increases from 2.28 hours to 3.05 hours.6 The area under the curve varies from 2103ng/mL*hr to 4544ng/mL*hr.6

Volume of distribution

Volume of distribution data is not readily available.Label,7

Protein binding

>90%.Label Canrenone is as much as 98% protein bound.6

Metabolism

Spironolactone is deacetylated to 7α-thiospironolactone.2,3 7α-thiospironolactone is S-methylated to 7α-thiomethylspironolactone or undergoes an elimination reaction to canrenone.2,3 7α-thiomethylspironolactone is reduced to 3α-hydroxythiomethylspironolactone or 3β-hydroxythiomethylspironolactone.2,3

Canrenone was originally thought to be the primary circulating metabolite, however more recent studies have demonstrated that the primary metabolite is actually 7α-thiomethylspironolactone.8,9

Route of elimination

Metabolites of spironolactone are excreted 42-56% in urine, and 14.2-14.6% in the feces.6 No unmetabolized spironolactone is present in the urine.6

Half-life

1.4 hours.Label,7

Canrenone has a half life of 16.5 hours, 7-α-thiomethylspirolactone has a half life of 13.8 hours, and 6-ß-hydroxy-7-α-thiomethylspirolactone has a half life of 15 hours.Label,7

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 functionsLabel.

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
