Heart disease generics could save UK £200m

Using a generic drug to treat hypertension and heart failure, instead of branded medicines from the same class, could save the UK National Health Service (NHS) at least £200 million in 2011 without any real reduction in clinical benefits.

That is the key finding of a systematic review, statistical meta-analysis and cost-effectiveness analysis just published online by International Journal of Clinical Practice (IJCP).

Researchers from University College London Hospitals NHS Foundation Trust looked at 14 hypertension and heart studies published between 1998 and 2009 on 16,179 patients.

Just over two-thirds of the patients were male (68 per cent), with an average age of 60 years.

They set out to compare the clinical benefits and cost-effectiveness of using the market leader candesartan instead of generic losartan, which is now considerably cheaper.

“When drugs are first launched they are protected by patents and relatively expensive as the pharmaceutical companies need to recover their research and development costs” explains lead author Dr Anthony Grosso.

The NHS currently spends more than £250 million a year on angiotensin-II receptor blockers (ARB) for high blood pressure and heart failure, with candesartan – which is still under patent and marketed under a number of brand names – currently dominating the market.

“Our comparative research showed that candesartan reduced blood pressure slightly more than losartan, with diastolic readings averaging 2mmHg lower and systolic readings 3mmHg lower” says Dr Grosso. “However, this difference is unlikely to be cost effective, particularly when it is prescribed in combination with other drugs.

“When we took all the factors into account, based on the evidence we reviewed, it was clear that losartan was likely to be the most cost-effective ARB to treat high blood pressure or heart failure.”

The authors estimate that using generic losartan as the angiotensin-II receptor blocker of choice could save the NHS approximately £200 million in 2011. “This figure is based on 2009 prescribing figures for primary care alone, so the actual savings could be even higher” says Dr Grosso.

In an accompanying editorial, Dr Rubin Minhas, Clinical Director & Editor-in-Chief of the BMJ Evidence Centre, stresses the need for the NHS to achieve clinically effective cost savings against a background of stringent public sector cuts and proposed NHS reforms.
