🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionSpironolactone is well absorbed from the gastrointestinal tract after oral administration. Food may increase the bioavailability of spironolactone.
DistributionSpironolactone and its metabolites are widely distributed in body tissues. It crosses the placenta and is excreted in breast milk.
Protein BindingSpironolactone is highly protein-bound (more than 90%) to plasma proteins, primarily albumin.
MetabolismSpironolactone is extensively metabolized in the liver to active metabolites, including canrenone and 7-alpha-thiomethylspirolactone, which contribute to its pharmacological effects.
Half-LifeThe elimination half-life of spironolactone is approximately 1.4 to 1.6 hours, but its active metabolites have longer half-lives, ranging from 13 to 24 hours.
ExcretionSpironolactone and its metabolites are primarily excreted in urine and to a lesser extent in bile and feces.
BioavailabilityThe bioavailability of spironolactone is approximately 90% when taken with food.
Onset of ActionThe diuretic effect begins gradually, typically within 2 to 3 days of starting therapy.
Peak Plasma TimePeak plasma concentrations of spironolactone are reached approximately 1 to 3 hours after oral administration.
Duration of ActionThe diuretic effect may last for 2 to 3 days after a single dose, but continuous therapy is needed for sustained effect.

How It Works

This medicine works by competitively inhibiting aldosterone receptors in the distal tubules of the kidney. Aldosterone normally promotes sodium reabsorption and potassium excretion. By blocking these receptors, this medicine increases sodium and water excretion while retaining potassium. This leads to reduced fluid retention and lowered blood pressure. It also has anti-androgenic effects, which can cause breast tenderness and enlargement in men.

Mechanism Steps

1
Binding to mineralocorticoid receptor: This medicine binds to the mineralocorticoid receptor in the kidney's distal tubule, preventing aldosterone from binding.
2
Inhibition of sodium reabsorption: Without aldosterone action, sodium reabsorption is reduced, leading to increased sodium and water excretion.
3
Potassium retention: Potassium excretion is decreased, which helps maintain normal potassium levels.
4
Diuresis and blood pressure reduction: The net effect is increased urine output and reduced blood volume, leading to lower blood pressure and reduced edema.

Elderly DosageElderly patients may be more sensitive to the effects of this medicine, especially dizziness and hyperkalemia. Start with lower doses and monitor closely. Dose must be individualized by a qualified clinician.
Renal ImpairmentUse with caution in patients with renal impairment. Dose reduction may be necessary. Contraindicated in severe renal impairment. Monitor potassium and kidney function closely.
Hepatic ImpairmentUse with caution in patients with hepatic impairment. May cause fluid and electrolyte imbalances. Monitor liver function and electrolytes.
Maximum Daily DoseThe maximum recommended daily dose is 400 mg, but doses above 100 mg are rarely used. Dose must be individualized by a qualified clinician.
