The difference between imported and domestic chemotherapy drugs can be seen in the following three aspects: 1. price, the price of imported chemotherapy drugs is usually several times that of domestic drugs, the price gap is very huge. 2. the therapeutic effect of the drug. Because of the gap between domestic pharmaceutical technology and foreign countries, the effect of imported chemotherapy drugs are generally better than similar domestic drugs. But in recent years, with the improvement of domestic pharmaceutical technology and technology, the difference is getting smaller and smaller, and some of the drugs even have no difference in efficacy. 3, side effects, the size of the side effects also have a certain relationship with the pharmaceutical process and technology, generally speaking, the side effects of domestic drugs are slightly larger than the imported drugs of the same kind, but the difference is not orders of magnitude, and this difference is also getting smaller and smaller. In short, imported chemotherapy drugs are better than their domestic counterparts in terms of efficacy and side effects, but the difference is not obvious, while the difference in price is obvious.
