A corresponding patient information leaflet on USE OF PINDOLOL IN PREGNANCY is available.

Pindolol is a non-selective beta blocker licensed for the treatment of hypertension and angina pectoris.

Data on rates of most specific pregnancy outcomes following gestational exposure to pindolol are extremely limited. A number of randomised controlled trials have all found no effects on fetal growth. The very limited available data do not raise concern of effects on preterm delivery rates, but are too limited to rule this out. There are no other published data quantifying pregnancy outcomes following pindolol exposure. An evidence-based assessment of the absolute risks of congenital malformation, miscarriage, stillbirth, preterm birth and adverse neurodevelopmental effects is therefore not possible.

Studies of beta blockers as a class do not show that use during pregnancy is associated with fetal structural malformation. Use of beta blockers in pregnancy has been associated with adverse effects on fetal growth, although because maternal hypertension is linked to intrauterine growth restriction, the relative contribution of beta blocker exposure to this outcome remains unquantified. Overall, data do not suggest that gestational beta blocker exposure increases the risk of preterm delivery. Data on rates of miscarriage, stillbirth and neurodevelopmental outcomes are too limited to permit a risk assessment.

Use of beta blockers near term may result in neonatal beta-adrenoceptor blockade, leading to neonatal bradycardia, hypotension and hypoglycaemia. Respiratory distress has also been reported. Assessment of the neonate for these effects is advised.

Exposure to pindolol at any stage in pregnancy would not be regarded as medical grounds for termination of pregnancy. Additional fetal monitoring is generally indicated in pregnancies complicated by hypertension and/or maternal cardiac disease, regardless of pharmacotherapy. Additional growth scans should be offered following gestational exposure to beta blockers. Other risk factors may be present in individual cases which may independently increase the risk of adverse pregnancy outcome. Clinicians are reminded of the importance of consideration of such factors when performing case-specific risk assessments.
