The use of medication in secondary and tertiary prevention is well established, for example, antihypertensives for asymptomatic hypertension to prevent ischaemic heart disease (IHD), and warfarin for ischaemic stroke survivors to prevent further strokes. Similarly, combination medicines containing more than one active ingredient, such as co-amilofruse, co-amoxiclav and co-codamol, which can simplify treatment regimens and improve patient adherence [1] have long been in regular use in both secondary and tertiary prevention.
