cover general costs." "'" However, the price discrepancies we have described make it clear that this 'contribution margin' cannot be distributed evenly. l3" This system of adding a premium to the actual production cost of all drugs has the advantage that a few of the best-selling drugs effectively subsidise the cost of drugs for rarer diseases. (Commonly 50% of a company's sales are made up by only about 5% of their product range.)1321 Third World patients do of course benefit, because rich world purchasers are helping to pay for drugs for tropical diseases that might otherwise be even more prohibitively expensive as their sales volume is low. But drugs for specifically 'tropical' diseases are only one aspect of a poor country's needs. Most of the medicines urgently needed by the Third World poor are for common infections and are decades old. Hardly 5% of the WHO selection of essential drugs are covered by valid patents, so they could be obtained as generics at competitive prices.(33) Furthermore, as the British industry-funded Office of Health Economics points out, the research and development costs for these drugs "have largely been paid for". (34) SHOULD THE POOR SUBSIDISE NEW DRUGS FOR THE RICH? Without doubt, new drug research is vital. It offers the only hope to many suffering from incurable diseases. Research and development is, of course, a high-risk and costly business. This is beyond dispute. The question is, should the Third World poor have to help pay for it and how relevant is the research to their needs?<35> On average it takes about a decade and costs around £35 million to develop a new drug. It can cost as much as £50 million.(36) When a company makes a major breakthrough its huge investment in time and money is usually amply rewarded, although not of course immediately. It was reported that Smith Kline & French's record-breaking new drug Tagamet, for gastric ulcers, should bring in £2,000 million in sales over ten years on an investment of about £17 million. After its launch the company reported a 45% rise in turnover and a 90% rise in profit.(37) It has recently been forecast that the British company Glaxo, which spent about £45 million on research and development in 1980/81 may make profits of between £30 and £40 million a year averaged out over the next five years from the launch of its rival anti-ulcer drug, Zantac. (3S| But these major breakthroughs are obviously relatively few and far between. Profitability depends on bringing out new products, irrespective of whether they offer any major advantage over existing drugs. A 1981 report by the British licensing authorities reveals that of the 604 new product licences approved in 1980, only 23 were for new chemical entities as opposed to new formulations of existing molecules and active compounds. Over the period from September 1971 to 1980 less than 6% of licences granted in Britain were for new chemical entities.(39) Some new formulations of existing compounds are of course extremely valuable. But figures from the United States Food and Drugs Administration (FDA) reveal 51
