Beta-blocker drugs for high blood pressure during pregnancy

Labetalol is a beta-blocker considered safe for use during pregnancy to treat high blood pressure.

Common beta-blocker for high blood pressure

Bisoprolol, a beta-1 selective blocker, is a common choice to treat high blood pressure.

Thiazide diuretics' blood pressure lowering action

Thiazide diuretics like bendroflumethiazide reduce blood pressure by inhibiting the sodium/chloride cotransporter in the nephron, decreasing water and ion absorption, leading to increased urination and lower blood volume.

Spironolactone's mechanism of action

Spironolactone is an aldosterone receptor antagonist, reducing sodium reabsorption and potassium excretion. This lowers blood pressure.
