A "memory pill" that could aid exam revision and help to prevent people forgetting important anniversaries may soon be available over the counter.
The medicine has been designed originally to help treat Alzheimer’s disease, a disease marked by progressive loss of mental capacity resulting from degeneration of the brain cells, but could be adapted and licensed for sale in a weaker form within the next few years.
One brand of memory-enhancing pill is being developed by the multinational company AstraZeneca in collaboration with Targacept, an American company, while Epix Pharmaceuticals, also from the US, is developing another.
Both have "cognitive-enhancing effects" which are aimed at treating patients with age-related memory loss.
Steven Ferris, a neurologist and former committee member of the Food and Drug Administration in the US, has predicted that a milder version will be available for healthy consumers as a "lifestyle pill" available over the counter.
Dr Ferris said: "My view is that one could gain approval, provided you showed the drugs to be effective and safe. It could be a huge market."
There is evidence that mind-improving drugs are already being taken in Britain by healthy users.
Provigil, which was used to treat narcolepsy, is being taken by some students to help them stay awake, while Adderall XR and Ritalin, treatments for attention deficit disorder, are being used to help promote concentration.
A spokesman of Adderall XR said: "We get a lot of calls from college campuses asking about it".
"There are risks though. It can raise blood pressure, people shouldn’t do it."
The Department of Health said it was not illegal to buy the medicines over the Internet, but it was not recommended.
Barbara Sahakian, professor of clinical neuropsychology at Cambridge, said: "It’s hard to quantify the scale of the phenomenon but it’s definitely catching on."
"The reality is we are not always at our best. After being up at night looking after the kids or travelling, many people would love to have something to refresh them. It’s not prohibited to drink Red Bull. The principle with cognition enhancers is not so different."
The "memory pill", as is mentioned in the first paragraph, is not sold over the counter now mainly because _____.
选项
A、it is not safe enough
B、it is not efficient enough
C、it has not yet been mass-produced
D、it has not yet been tested on humans
答案
A
解析
第1、2段的内容都是关于memory pill,而第2段末尾的could be adapted…for sale…表明memory pill要经过改进才能销售,而且该句中的in a weaker form表明memory pill需要改进是因为这种药现在对正常人来说药性太强,由此可以推断memory pill对正常人来说还不够安全,还不能投放市场,因此,本题应选A。
