A pill，code-named HT-0712，may make forgetfulness a thing of the past. It is being developed in the US and could go on sale within five years.

According to the newspaper The Sun，the wonder drug has been nicknamed “Mind Viagra”and has already been shown to boost the memory power of mice and flies. Next it will be tested on humans. This is just one of a number of drugs in a pharmaceutical (制药的) race to develop an increased memory pill. At least 12 US companies are believed to be working on similar projects.

Tim Tully，the founder of US drug company Helicon Therapeutics，who is in charge of the HT-0712 project，gave this practical example of its use for students：“If it takes two weeks to memorize a verse of Shakespeare，with one of these drugs you might be able to do it in two or three days. ”

“The memory drug business appears to be set to become a multi-million dollar industry，”experts say. This summer，100 Americans suffering mild memory loss will test HT-0712 in the first experiment on people.

“You don’t think better than you did before，you just get the facts in with less practice. There is a growing belief that memory and memory loss is just another treatable condition，”says Tully.

However，there is some doubt whether the drugs can really improve memory. In a study by the US’s Yale University Medical School，researchers suggested that the drug might affect other parts of the memory.
