An intravenous heart-support and blood-vessel-relaxing medicine
Dopexamine
An intravenous medicine used in hospital to help a weak heart pump and to relax blood vessels, improving blood flow.
What is Dopexamine?
Dopexamine is a hospital-only medicine used to support the heart and improve blood flow in seriously unwell patients, such as those with severe heart failure or recovering from major surgery. It both helps the heart pump and relaxes blood vessels so blood moves more easily around the body. It is given as a continuous drip into a vein. Because it stimulates the heart, it can cause a fast heartbeat or an irregular rhythm, so it is only used in hospital with continuous monitoring of the heart rhythm and blood pressure.

What it is
Dopexamine is a medicine used in hospital to support patients whose heart is struggling or who need extra help with blood flow, for example in severe heart failure or during recovery from major surgery. It has two main actions: it helps the heart pump more effectively and it relaxes blood vessels so blood circulates more easily. It is given only as a drip into a vein, usually in a high-dependency or intensive-care setting, and is closely supervised. It is not a medicine used at home.
How it works
Dopexamine stimulates receptors that make the heart pump more strongly and faster, and at the same time it widens blood vessels so there is less resistance for the heart to pump against. Together these actions can improve how much blood reaches the body's organs when the circulation is struggling. Because it speeds up and stimulates the heart, it can also cause palpitations or an irregular rhythm and increase the heart's workload. It acts and wears off quickly, so the drip can be adjusted closely while the team watches the heart and blood pressure.

Weighing it up
Advantages & disadvantages of Dopexamine
Advantages
- Supports a struggling heart while also relaxing blood vessels to ease blood flow.
- Can improve blood flow to the body's organs when the circulation is failing.
- Acts quickly and wears off quickly, allowing close adjustment.
Disadvantages
- Can cause a fast heartbeat or an irregular heart rhythm.
- Increases the heart's workload and can affect blood pressure.
- Can only be given in hospital with continuous monitoring.
Practical use
Good to know
Dopexamine is a specialist hospital medicine, given as a finely controlled drip and adjusted according to how the patient responds. The key thing to understand is that it works in two ways at once: supporting the heart's pumping while relaxing blood vessels to ease blood flow. Because it stimulates the heart, the most common effects are a faster heartbeat and, in some people, an irregular rhythm, which is why continuous heart monitoring is essential. It can also affect blood pressure. The team balances the benefit of keeping blood flowing to the organs against the strain it puts on the heart, and uses it for as short a time as the situation allows, reducing the drip gradually rather than stopping it abruptly.
Who should not take it / use with caution
- People who have had a serious allergic reaction to dopexamine should not be given it.
- It is used with great care in certain heart conditions where stimulating the heart could be harmful.
- It is only ever given under specialist supervision with continuous heart monitoring.
Monitoring
- Continuous monitoring of the heart rhythm while it is running.
- Close watching of blood pressure and blood flow to the organs.
- Regular review of whether it is still needed and adjusting the drip accordingly.
Side effects
- A faster heartbeat or palpitations.
- An irregular heart rhythm in some people.
- Nausea, tremor, or changes in blood pressure.
Key interactions
- Other medicines affecting the heart rate, rhythm or blood pressure may add to its effects and are reviewed by the team.
- Certain beta-blockers and other heart medicines can change how it works.
- Because it is used in intensive settings, all of a patient's medicines and drips are considered together.
Available as: A solution given as a drip into a vein in hospital.

As well as helping the heart pump, it relaxes blood vessels so blood circulates more easily, working in two ways at once.
Why does it need close monitoring?
Because it stimulates the heart it can cause a fast or irregular heartbeat and affect blood pressure, so the heart rhythm and blood pressure are watched continuously.
How is it given?
It is given only in hospital as a continuous drip into a vein, with the rate carefully adjusted by trained staff.
Can it be used at home?
No. Dopexamine is only used in a hospital setting under close supervision and is never taken at home.
