Amiloride has mild diuretic and anti-hypertensive activity. It acts primarily in the distal tubule and does not require aldosterone for its action. Amiloride is a mild natriuretic which does not initiate a concomitant decrease in potassium levels.

Hydrochlorothiazide is a diuretic with antihypertensive properties. It acts by inhibiting the renal tubular re-absorption of sodium and chloride ions, which are excreted with an accompanying volume of water. Potassium excretion is also promoted.

Timolol is a non-selective beta-adrenergic receptor blocking agent that does not have significant intrinsic sympathomimetic, direct myocardial depressant, or local anaesthetic activity. Timolol reduces intra-ocular pressure, whether or not this is associated with glaucoma.
