Celiprolol is a beta blocker with vasodilating properties. It is a selective beta1-receptor antagonist, meaning it primarily blocks the effects of adrenaline and noradrenaline on the heart. This leads to a reduction in heart rate and blood pressure. Celiprolol also possesses vasodilating effects through its interaction with the potassium channels in vascular smooth muscle cells, leading to relaxation of blood vessels and further lowering blood pressure. Celiprolol has been studied extensively for its potential therapeutic benefits in treating hypertension, angina, and other cardiovascular conditions. Its unique combination of beta-blocking and vasodilating properties offers a promising approach to manage these conditions. However, it has been largely replaced by newer beta-blockers with better side-effect profiles.'

Celiprolol is a beta 1 selective adrenoreceptor blocker with partial beta 2 agonism and direct vasodilator activity. It causes renal vasodilation by increasing tissue nitric oxide (NO) levels.
Celiprolol has shown equivalent antihypertensive efficacy to other beta-blockers, notably propranolol, atenolol, metoprolol and pindolol. It has a slightly beneficial effect on serum lipid profiles, and does not appear to exert adverse effects on carbohydrate metabolism.
