Augmentin vs Spironolactone: brand vs ingredient
Augmentin contains Amoxicillin, Clavulanate, while Spironolactone is a different active ingredient in the Potassium-sparing diuretic / aldosterone antagonist class. This page compares them: when each is used, how the mechanisms and indications differ, and whether the question "Augmentin vs Spironolactone" makes sense to ask at all.
What is the relationship?
Augmentin and Spironolactone are different things: Augmentin is a branded medication whose active ingredient is Amoxicillin, Clavulanate (in the Antibiotics class), whereas Spironolactone is in the Potassium-sparing diuretic / aldosterone antagonist class.

When Spironolactone is used
Spironolactone is approved for heart failure with reduced ejection fraction, primary hyperaldosteronism, resistant hypertension, oedema in cirrhosis or nephrotic syndrome, and certain potassium-loss states.
Mechanisms compared
Augmentin: Amoxicillin inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), but is hydrolysed by beta-lactamase enzymes produced by some resistant bacteria. Spironolactone: Spironolactone competitively blocks the mineralocorticoid (aldosterone) receptor in the distal tubule of the kidney, reducing sodium reabsorption and potassium excretion.

Comparing Augmentin with Spironolactone makes sense when both are in the same clinical decision: the prescriber has weighed both for different but related conditions. If the question is between two options for the same need, the prescriber decides based on prior response, comorbidities and tolerance.
