Canrenone, sold under the brand names Contaren, Luvion, Phanurane, and Spiroletan, is a steroidal antimineralocorticoid [3] [4] of the spirolactone group related to spironolactone which is used as a diuretic in Europe, including in Italy and Belgium. [5] [6] [7] [8] It is also an important active metabolite of spironolactone, and partially accounts for its therapeutic effects. [9] [2]

Contents

Medical uses

Canrenone has been found to be effective in the treatment of hirsutism in women. [10]

Heart failure

Two studies of canrenone in people with heart failure have shown a mortality benefit compared to placebo. In the evaluation which studied people with chronic heart failure (CHF), people that were treated with canrenone displayed a lower number of deaths compared to the placebo group, indicating a death and morbidity benefit of the medication.

One study compared 166 treated with canrenone to 336 given conventional therapy lasting 10 years. Differences in systolic and diastolic blood pressure was observed between both patient groups where, patients treated with canrenone, showed a lower blood pressure compared to conventional therapy. Uric acid was lower in the group treated with canrenone; however, no differences were seen in potassium, sodium, and brain natriuretic peptide (BNP) levels. Left ventricular mass was also lower in the group treated with canrenone and a greater progression of NYHA class was observed in the control group compared to patients treated with canrenone. [11]

Another study concluded that treatment with canrenone in patients with chronic heart failure improves diastolic function and further decreased BNP levels. [12]

Pharmacology

Pharmacodynamics

Canrenone is reportedly more potent as an antimineralocorticoid relative to spironolactone, but is considerably less potent and effective as an antiandrogen. [13] [14] Similarly to spironolactone, canrenone inhibits steroidogenic enzymes such as 11β-hydroxylase, cholesterol side-chain cleavage enzyme, 17α-hydroxylase, 17,20-lyase, and 21-hydroxylase, but once again, is comparatively less potent in doing so. [15]

Pharmacokinetics

The elimination half-life of canrenone is about 16.5 hours. [2]

As a metabolite

Canrenone is an active metabolite of spironolactone, canrenoic acid, and potassium canrenoate, and is considered to be partially responsible for their effects. [9] It has been found to have approximately 10 to 25% of the potassium-sparing diuretic effect of spironolactone, [16] whereas another metabolite, 7α-thiomethylspironolactone (7α-TMS), accounts for around 80% of the potassium-sparing effect of the drug. [17] [18] [19]

Antihypertensives are a class of drugs that are used to treat hypertension. Antihypertensive therapy seeks to prevent the complications of high blood pressure, such as stroke, heart failure, kidney failure and myocardial infarction. Evidence suggests that reduction of the blood pressure by 5 mmHg can decrease the risk of stroke by 34% and of ischaemic heart disease by 21%, and can reduce the likelihood of dementia, heart failure, and mortality from cardiovascular disease. There are many classes of antihypertensives, which lower blood pressure by different means. Among the most important and most widely used medications are thiazide diuretics, calcium channel blockers, ACE inhibitors, angiotensin II receptor antagonists (ARBs), and beta blockers.

Eplerenone, sold under the brand name Inspra, is an aldosterone antagonist type of potassium-sparing diuretic that is used to treat chronic heart failure and high blood pressure, particularly for people with resistant hypertension due to elevated aldosterone. It is a steroidal antimineralocorticoid of the spirolactone group and a selective aldosterone receptor antagonist (SARA).

<span class="mw-page-title-main">Potassium canrenoate</span> Pharmaceutical drug

Potassium canrenoate or canrenoate potassium (USAN), also known as aldadiene kalium, the potassium salt of canrenoic acid, is an aldosterone antagonist of the spirolactone group. Like spironolactone, it is a prodrug, and is metabolized to active canrenone in the body.

<span class="mw-page-title-main">Spirolactone</span>

Spirolactones are a class of functional group in organic chemistry featuring a cyclic ester attached spiro to another ring system. The name is also used to refer to a class of synthetic steroids, called steroid-17α-spirolactones, 17α-spirolactosteroids, or simply 17α-spirolactones, which feature their spirolactone group at the C17α position. They are antimineralocorticoids, or antagonists of the mineralocorticoid receptor, and have been employed clinically as potassium-sparing diuretics. Some also possess progestogenic and/or antiandrogen properties, which have both contributed to side effects and been utilized for medical indications. The spirolactones were developed by G. D. Searle & Company in the 1950s and thereafter and were denoted as "SC" compounds.

<span class="mw-page-title-main">Prorenone</span> Chemical compound

Prorenone is a steroidal antimineralocorticoid of the spirolactone group related to spironolactone that was never marketed. It is the lactonic form of prorenoic acid (prorenoate), and prorenoate potassium (SC-23992), the potassium salt of prorenoic acid, also exists. Prorenoate potassium is about 8 times more potent than spironolactone as an antimineralocorticoid in animals, and it may act as a prodrug to prorenone. In addition to the mineralocorticoid receptor, prorenone also binds to the glucocorticoid, androgen, and progesterone receptors. The antiandrogenic potency of prorenone in vivo in animals is close to that of spironolactone. Similarly to spironolactone, prorenone is also a potent inhibitor of aldosterone biosynthesis.

<span class="mw-page-title-main">Mexrenone</span> Chemical compound

Mexrenone is a steroidal antimineralocorticoid of the spirolactone group related to spironolactone that was never marketed. It is the lactonic form of mexrenoic acid (mexrenoate), and mexrenoate potassium (SC-26714), the potassium salt of mexrenoic acid, also exists. In addition to the mineralocorticoid receptor, mexrenone also binds to the glucocorticoid, androgen, and progesterone receptors. Relative to spironolactone, it has markedly reduced antiandrogen activity. Eplerenone is the 9-11α-epoxy analogue of mexrenone.

<span class="mw-page-title-main">SC-5233</span> Chemical compound

SC-5233, also known as 6,7-dihydrocanrenone or 20-spirox-4-ene-3,20-dione, is a synthetic, steroidal antimineralocorticoid of the spirolactone group which was developed by G. D. Searle & Company in the 1950s but was never marketed. It was the first synthetic antagonist of the mineralocorticoid receptor to have been identified and tested in humans. The drug was found to lack appreciable oral bioavailability and to be of low potency when administered parenterally, but it nonetheless produced a mild diuretic effect in patients with congestive heart failure. SC-8109, the 19-nor (19-demethyl) analogue, was developed and found to have improved oral bioavailability and potency, but still had low potency. Spironolactone followed and had both good oral bioavailability and potency, and was the first synthetic antimineralocorticoid to be marketed. It has about 46-fold higher oral potency than SC-5233.

<span class="mw-page-title-main">Mespirenone</span> Chemical compound

Mespirenone (INN), also known as Δ1-15β,16β-methylenespironolactone, is a steroidal antimineralocorticoid of the spirolactone group related to spironolactone that was never marketed. Animal research found that it was 3.3-fold more potent as an antimineralocorticoid relative to spironolactone. In addition to its antimineralocorticoid properties, mespirenone is also a progestogen, antigonadotropin, and antiandrogen. It is 2- to 3-fold as potent as spironolactone as a progestogen and antigonadotropin but its antiandrogenic activity is markedly reduced and weak in comparison. Mespirenone is also a potent and specific enzyme inhibitor of 18-hydroxylase and thus of mineralocorticoid biosynthesis. The drug was under development by Schering and reached phase II clinical trials but was discontinued in 1989.

<span class="mw-page-title-main">SC-8109</span> Chemical compound

SC-8109 is a steroidal antimineralocorticoid of the spirolactone group which was never marketed. It is a potent antagonist of the mineralocorticoid receptor and is more potent than the related drug SC-5233. However, SC-8109 was found to have relatively low oral bioavailability and potency, though it nonetheless produced a mild diuretic effect in patients with congestive heart failure. Spironolactone, another spirolactone, followed and had both good oral bioavailability and potency, and was the first antimineralocorticoid to be marketed.

It is a derivative of progesterone (pregn-4-ene-3,20-dione) with a thio (sulfur) substitution at the C7α position, and is related to the spirolactone group of drugs but lacks a γ-lactone ring.

<span class="mw-page-title-main">Pharmacodynamics of spironolactone</span> Mechanisms of action

The pharmacodynamics of spironolactone, an antimineralocorticoid and antiandrogen medication, concern its mechanisms of action, including its biological targets and activities, as well as its physiological effects. The pharmacodynamics of spironolactone are characterized by high antimineralocorticoid activity, moderate antiandrogenic activity, and weak steroidogenesis inhibition. In addition, spironolactone has sometimes been found to increase estradiol and cortisol levels and hence could have slight indirect estrogenic and glucocorticoid effects. The medication has also been found to interact very weakly with the estrogen and progesterone receptors, and to act as an agonist of the pregnane X receptor. Likely due to increased activation of the estrogen and/or progesterone receptors, spironolactone has very weak but significant antigonadotropic effects.

<span class="mw-page-title-main">7α-Thiomethylspironolactone sulfoxide</span> Chemical compound

7α-Thiomethylspironolactone sulfoxide is a metabolite of spironolactone, an antimineralocorticoid and antiandrogen medication. 7α-TMS sulfoxide is specifically formed from 7α-thiomethylspironolactone (7α-TMS).
