The American pharmaceutical industry is relatively stable, and now it has been monopolized by several big companies. Several large manufacturing companies in the United States have now occupied their own territory in the American pharmaceutical industry, and basically completed the research and development of commonly used drugs and new drugs. The research and development cost of new drugs is very expensive, and it costs a lot of money to buy them. Sometimes they are still valuable and have no market.
The generic drugs of new drugs are similar and hard to buy. Moreover, these giants will not allow the existence of generic drugs for their own interests, and they are often severely hit. For example, lomustine, an anti-tumor drug, is an example. After so many years, the price has been very high. This drug was used to treat brain tumors, but its price has been very high since the advent of generic drugs without it.
Because of the welfare system in Europe and America, people who buy medical insurance really don't have to spend a lot of money to buy these drugs. In order to protect the rights and interests of their citizens, European and American countries have indeed introduced these benefits, but there are also restrictions, only for those with medical insurance. If everyone does this, the medicine will be worthless and prone to problems. So although it seems that the medical benefits in Europe and America are very good, they are only for a small number of people.
