Additive effects with catecholamine-depleting drugs, antihypertensives, phenothiazine, haloperidol, ergot alkaloids. May increase the risk of bradycardia with MAOIs, fingolimod. Potentiated effects with Ca channel blockers. May increase the risk of depression with diltiazem. May cause additive or antagonistic effects with other antiarrhythmics.

Tác dụng

Description:
Mechanism of Action: Nadolol is a non-selective β-adrenergic blocker that competitively blocks response to β₁- and β₂-adrenergic stimulation. It decreases portal pressure by producing splanchnic vasoconstriction thereby reducing portal blood flow. Additionally, it does not exhibit any membrane stabilising or intrinsic sympathomimetic activity.
Duration: 17-24 hours.
Pharmacokinetics:
Absorption: Incompletely absorbed from the gastrointestinal tract. Time to peak plasma concentration: Approx 3-4 hours.
Distribution: Widely distributed. Enters the breast milk. Volume of distribution: Approx 2 L/kg. Plasma protein binding: Approx 30%.
Metabolism: Not metabolised.
Excretion: Via urine (as unchanged drug). Elimination half-life: 20-24 hours.
