Beta-blockers

Celiprolol

A beta-blocker that eases the heart's workload and helps relax blood vessels to lower blood pressure.

What is Celiprolol?

Celiprolol is a beta-blocker used to lower high blood pressure. It acts mainly on the heart but also has a mild vessel-relaxing effect. Like other beta-blockers it should not be stopped suddenly, can mask the signs of a low blood sugar, and is generally avoided in asthma.

What it is

Celiprolol is a cardioselective beta-blocker that, unusually, also has some mild blood-vessel-relaxing activity. In the UK it is used to treat high blood pressure. Beta-blockers are no longer first choice for most people with blood pressure alone, but celiprolol remains an option, particularly where its vessel effects are helpful.

How it works

Celiprolol blocks beta receptors in the heart that respond to adrenaline, slowing the heart and reducing the force of each beat. At the same time it has a mild stimulating effect on other receptors that helps relax blood vessels slightly. Together these actions lower blood pressure with somewhat less slowing of the heart than older beta-blockers.

Company & origin

Originated / developed by: Originally developed by Rorer; available in the UK as a branded and generic medicine..

Introduced in the 1980s as a cardioselective beta-blocker with some vessel-relaxing activity, used in the UK for high blood pressure.

Practical use

How to take Celiprolol

General, dose-free guidance — always follow your prescriber's and the leaflet's specific instructions.

  • Take it in the morning, usually before food, as food can reduce its absorption.
  • Swallow the tablet with a drink of water.
  • Do not stop suddenly; any change is tapered down under guidance.
  • If you have diabetes, watch for low blood sugar, as warning signs may be less obvious.
  • If a dose is missed, take it when you remember unless the next one is near, then skip it; never double up.
  • Tell your prescriber if you become very tired, wheezy or notice a very slow pulse.

Weighing it up

Advantages & disadvantages of Celiprolol

Advantages

  • Lowers blood pressure with mild vessel-relaxing activity alongside its heart effect.
  • Tends to slow the heart less than some older beta-blockers.
  • Acts mainly on the heart (cardioselective), which can suit some people better.

Disadvantages

  • Absorption is reduced by food, so timing around meals matters.
  • Must not be stopped abruptly, which means planning ahead before any change.
  • Generally avoided in asthma and can mask low-blood-sugar warning signs in diabetes.

Practical use

Good to know

Celiprolol is usually taken in the morning, often before food, as food can reduce how well it is absorbed. It must not be stopped suddenly, as this can cause a rebound rise in heart rate or blood pressure. It can mask the warning signs of a low blood sugar, and people with asthma are generally advised to avoid beta-blockers because they can tighten the airways.

Who should not take it / use with caution

  • People with asthma or other wheezy lung conditions, as beta-blockers can tighten the airways.
  • People with a very slow heart rate, certain heart-block problems or uncontrolled heart failure.
  • People with severe circulation problems in the limbs, who may need an alternative.

Monitoring

  • Blood pressure and pulse
  • Symptoms of breathlessness or a very slow heartbeat

Side effects

  • Tiredness, dizziness, and sometimes cold hands and feet.
  • Headache or disturbed sleep with vivid dreams.
  • A slow heart rate, or wheeze in people prone to it; report severe breathlessness or a very slow pulse.

Key interactions

  • Other heart-rate-slowing medicines, such as certain calcium-channel blockers and digoxin, can slow the heart too much together.
  • Diabetes medicines — celiprolol can mask the warning signs of low blood sugar.
  • Other blood-pressure medicines can add to its effect and cause low pressure.

Available as: Tablets.

Answers

Celiprolol: frequently asked questions

When should I take celiprolol?

It is usually taken in the morning, often before food, because food can reduce how much is absorbed. Follow the timing your prescriber or pharmacist advises.

Can I stop celiprolol suddenly?

No. Stopping a beta-blocker abruptly can cause a rebound rise in heart rate or blood pressure. Any change is made gradually under your prescriber's guidance.

Is celiprolol safe with asthma?

Beta-blockers are generally avoided in asthma because they can tighten the airways. Tell your prescriber if you have asthma or wheezing so a safer option can be considered.

How is celiprolol different from other beta-blockers?

It acts mainly on the heart but also has a mild vessel-relaxing effect, and it tends to slow the heart a little less than some older beta-blockers.

Will celiprolol affect my diabetes?

It can mask some warning signs of a low blood sugar, such as a fast heartbeat. If you have diabetes, monitor your levels and watch for other symptoms such as sweating.
