Two new lipid-regulating drugs.

▼Evolocumab (Repatha-Amgen Ltd) and ▼alirocumab (Praluent-Sanofi) are the first in a novel class of lipid-regulating drugs, proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors, to be licensed in the UK. Both drugs have marketing authorisation for the treatment of primary hypercholesterolaemia (heterozygous familial and non-familial) or mixed dyslipidaemia and are administered by subcutaneous injection. Here we consider the evidence for evolocumab and alirocumab in the management of primary hypercholesterolaemia and dyslipidaemias.
