According to a domestic glaucoma epidemiological survey by Beijing Union Hospital last year，Clast -light eye has become my country's second largest common ophthalmology disease，The number of diseases accounts for 15%of the total number of domestic eye diseases，The fourth place to occupy blind eye disease。At present, the incidence of glaucoma in my country is about 1%。Because glaucoma is not as cataracts, it can be treated by surgery，can only be treated with the help of drugs，So for the past 8 years，my country's average annual growth rate of glaucoma drug markets is as high as 22%，far higher than the market growth rate of stake sports betting appother drugs。It is estimated to，At present, the annual sales of glaucoma drug market in my country are 1.5 billion to 2 billion yuan。 
It is understood，Before the 1980s，There are only a few kinds of glaucoma therapy drugs in the international market，After the 1990s，Foreign abroad has developed and listed dozens of glaucoma therapy drugs，There are 5 categories of eye medicines that only treat "open corner glaucoma"、20 varieties: prostaglandin derivatives，β-adrenal adrenal energy receptor blockers，adrenal agent，Carbonate enzyme inhibitors，Pupil shrinkable category。Currently in the international market，The largest share of prostaglandin derivatives，About 40%。International Ophthalmology experts believe，Prostaglandin drugs are the best effect on opening coriability glaucoma，Side effects are also minimal。But because its price is too expensive (the cheapest prostaglandin eye drops imported in my country also cost 338 yuan a)，and imported eye drops cannot be reimbursed，So current glaucoma patients in our country usually use domestic β-blockers glaucoma-like glaucoma，The most common variety is "Malacca acid?"。Due to long -term use of 噻 噻 (ie 噻 噻 心) will cause heart rate changes、Bronchial spasm and other symptoms，Therefore, developed countries have rarely used such eye medicines。
Since 噻? Lore exists with side effects，Entry prostaglandin drugs are expensive，So I think，Develop stake betting appprostaglandin general -purpose drugs，to replace imported products，There will be broad market space。
The practice of the United States FDA encourages the development of general -purpose drugs is worth our learning。It is understood，The high price of drug prices in the United States can be called the world's first，High drug prices have caused widespread dissatisfaction among the American citizens，So since 2000，FDA encourages pharmaceutical companies to produce universal name preparations，The premise is，The patent of the drug is about to expire or the market demand is great。Take paclitaxel as an example，This product market has long been monopolized by Shi Guibao Company，The price is extremely expensive。2002-2003，FDA successively approved the two companies to produce paclitaxel injection and go public as a general -purpose drug，This will greatly reduce the market sales price of paclitaxel injection，Welcome to the majority of tumor patients。
It is reported，American FDA is currently studying and adopting new policies to encourage pharmaceutical factories to develop and produce cheap glaucoma treatment drugs。Because，Clasting eye belongs to a major illness in the United States，1%to 2%Americans suffer from glaucoma。and the eye medicines for the treatment of glaucoma in the US market are mostly patented medicines，Variest price。A piece of information released by a recent US My stake betting appsurvey company shows that among 2696 glaucoma patients who were investigated，75%of people complained that the glaucoma in the hospital is too expensive; on average, each American glaucoma patient will spend $ 4050 a year for the treatment of this disease。Not long ago，Some members of the United States proposed a proposal for a joint name，It is recommended that pharmaceutical industries with low eye drops，It is best to sell for $ 2.5 to $ 4 per branch，so。It is said that the FDA is seriously studying the feasibility of this proposal and preparing to take corresponding measures，and the plan proposed by the FDA is，The price of each glaucoma eye medicine is controlled within $ 10。But the American pharmaceutical industry questioned this，Who is willing to produce low -priced glaucoma eye medicine? At present, even the old products such as the market in the US market are priced at $ 10 to $ 20，Not to mention the new prostaglandin derivatives who have just been developed and listed for a long time.。From this perspective，Prostaglandin new glaucoma eye drugs are unlikely to reduce prices in a short period of time。
and the current number of patients in glaucoma in my country is constantly rising，has risen from 0.0%20 years ago to about 1%of the current 1%。And many glaucoma patients live in the low -income class where the countryside or the city lives，They usually do not take the initiative to go to the hospital for ophthalmology examination，Only when stake online sports bettingthe vision drops sharply，At this time, glaucoma is often very serious。I think，As the US government is vigorously advocating the development of cheap glaucoma eye medicines，The Chinese government should also follow the trend，Encourage and guide enterprises to develop new glaucoma therapy drugs，Demonstration of medication for many low -income glaucoma patients in China。
