ADHD drug treatments in the balanceDate: 01/10/2007 09:33:53

Global pharmaceutical company Eli Lilly is fighting a tough battle to protect the patent on its ADHD drug Strattera.
Lawyers are reported to have highlighted the difficulty of the pharmaceutical company's case, with other producers justifying their imitations of the drug on grounds of obviousness.
The drug, Strattera (Atomoxetine), is the first non-stimulant treatment approved for tackling ADHD, the attention deficit problem affecting the concentration of many children and others.
But while Eli Lilly fights to protect its patent, US researchers at the Mayo Clinic, Minnesota, claimed that prescription stimulants have proven to be a better alternative to a drug like Strattera.
The 18-year study showed that long-term prescription of stimulants like Ritalin paved the way for greater academic success than without.
Dr William Barbaresi, lead author of the research reports, hailed a breakthrough which had shown the durable benefits of stimulants in the class-room.
"Previously, there was evidence that treatment with stimulant medications improved short-term academic performance, but there was no good evidence that long-term outcomes are better with stimulant treatment" he said.
But whatever the indications of successful stimulant-based treatment, Eli Lilly will be fighting hard to protect the patent on what is currently the only approved non-stimulant drug for treating ADHD.
