ScienceDaily (Nov. 2, 2011) -- A landmark study in mice identifies a biological mechanism that could help explain how tobacco products could act as gateway drugs, increasing a person's future likelihood of abusing cocaine and perhaps other drugs as well, according to the National Institute on Drug Abuse (NIDA), part of the National Institutes of Health. The study is the first to show that nicotine might prime the brain to enhance the behavioral effects of cocaine.

Pfizer Ordered to Withdraw Advertising

FDA Feeling The Heat


FDABy Evelyn Pringle

Over the past year, the Bush administration's FDA has been the focus of non-stop investigations and with the Democrats in control of Congress, a long overdue overhaul of the agency is in the cards.

The Government Accountability Office has identified serious problems within the FDA. In an April 21, 2006, report, the GAO found the FDA's performance "disorganized," "bureaucratic," and undermined by infighting between drug evaluation administrators whose allegiance is with the pharmaceutical industry, and the Office of Drug Safety.

According to the GAO, the drug safety office is under-funded, lacks independence and lacks decision-making responsibility. It also criticized the way FDA scientists were prevented from speaking at advisory committee meetings on drugs they were studying.

U.K. researchers tout new drug development model

drug developmentTwo UK-based academics have devised a way to invent new medicines and get them to market at a fraction of the cost charged by big drug companies, enabling millions in poor countries to be cured of infectious diseases and potentially slashing the NHS drugs bill.

Sunil Shaunak, professor of infectious diseases at Imperial College, based at Hammersmith hospital, calls their revolutionary new model "ethical pharmaceuticals".

Improvements they devise to the molecular structure of an existing, expensive drug turn it technically into a new medicine which is no longer under a 20-year patent to a multinational drug company and can be made and sold cheaply.

Animal studies 'of limited use'

lab mouse Tests of drugs on animals are not reliable in all cases, a study warns.

The British Medical Journal research looked at studies in six areas and found animal studies agreed with human trials in just three.

The high-profile London drug trial which left six men ill was carried out after animal studies showed the drug TGN1412 was effective.

This study, led by Professor Ian Roberts, suggests animal studies should be used, but not for all drug research.

FDANot all companies are getting what they want for Christmas. Taking on the form of the FDA, Santa has left a lump of coal in some corporate stockings when approvable letters were issued to four companies. Remember that receipt of an approvable letter means that the FDA has some outstanding issues that need to be resolved before an approval can be issued.

These outstanding issues can be quite complex, involving a great deal of time and investment, such as new clinical trials, or relatively simple, such as a label adjustment or a manufacturing process issue. In any case, it means a delay, either slight or lengthy, in getting to market.

New River Pharmaceuticals (NRPH) and Shire (SHPGY)- A second approvable letter was issued to these two companies for a treatment for Attention Deficit Hyperactivity Disorder [ADHD]. The first approvable letter was issued on October 6, 2006 and the company speedily submitted a response on October 24, 2006. According to Yahoo Finance, the FDA is not requesting new studies.
