The Giant PANDA study: which blood pressure medication is best for pregnant women with high blood pressure?

Medical Conditions

Oedema, proteinuria and hypertensive disorders in pregnancy, childbirth and the puerperium


This information is provided directly by researchers and we recognise that it isn't always easy to understand. We are working with researchers to improve the accessibility of this information.


Around 10% of women in the UK have high blood pressure in pregnancy, which without treatment can cause serious complications for the woman and baby. We want to find out which of the two most commonly used medicines to treat high blood pressure in pregnancy (labetalol and nifedipine) in the NHS is best at treating high blood pressure without having troublesome side effects for the woman or baby. Both medications have been widely used in the UK for many years and are considered safe in pregnancy.
The study aims to find out which blood pressure medication is best at treating high blood pressure in pregnancy.
Study results will help to understand which medication best treats high blood pressure in pregnancy and is safe for the baby, helping doctors and women with high blood pressure decide which medication is best for each woman and their baby.

Start dates may differ between countries and research sites. The research team are responsible for keeping the information up-to-date.

Over 2,300 pregnant women with high blood pressure from around 50 maternity units in the UK that need treatment for their blood pressure will be offered information about the study and decide if they would like to take part. Women will be asked for their consent to take part and to complete a short questionnaire about how they are feeling. Women will then be randomly allocated (by chance) to either labetalol or nifedipine using a computer. To ensure women are treated safely, women and their healthcare team will know which medication group they are in. All women will continue to have their usual antenatal care including adding and switching their blood pressure medication and changing dose as needed. Two weeks after joining the study women will be asked to complete a few short questionnaires about how they are finding their blood pressure medication. Women and their babies will be followed through the pregnancy until they leave the hospital after birth.


Pregnant women with hypertension, aged 18 years or over

Taking part will help us to understand how best to treat women with high blood pressure in pregnancy. Because women were about to be prescribed one of these two medications to treat their high blood pressure, there is very little risk to taking part. The only possible disadvantage is the additional time spent with the study team. We will keep these contacts as brief as possible, and if it is easier for women the two-week check-in can be over the phone or by email.
The doctor or healthcare professional prescribing their medication will explain any side effects as they usually would, and they can ask them at any time if they are not sure. The commonest side-effect reported for both drugs in pregnancy is a headache. Some women also reported dizziness or breathlessness. All women will continue to receive their usual NHS care during pregnancy while in this study.


The study is sponsored by University of Birmingham and funded by NIHR Evaluation, Trials and Studies Co-ordinating Centre (NETSCC); Grant Codes: NIHR128721; National Institute for Health Research (NIHR) (UK).
