"Smokable" pain drugs promise faster action

BOSTON (Reuters) - All self-respecting painkillers these days offer "fast-acting relief," a promise we accept to mean anywhere from 15 minutes to more than an hour.

For Alexza Pharmaceuticals Inc., which is developing drugs for migraine, pain, panic and agitation, "fast" has to mean "within seconds."

The Palo Alto, California-based company is developing drugs that can be "smoked," and, like nicotine in cigarettes, pass through the lungs and into the bloodstream almost instantly.

Investors like the idea.

Alexza's shares have risen nearly 60 percent over the past five months, dramatically outperforming the Nasdaq Biotechnology Index, which rose 15 percent over the same period.

"What makes this an exciting story is how broadly applicable the technology could prove to be," said Charles Duncan, an analyst at JMP Securities, which helped take the company public for $8 a share a year ago.

Alexza was formed by biotechnology entrepreneur Alejandro Zaffaroni, who also founded nicotine-patch developer Alza. His latest venture is not the only company that is developing inhaled therapies: Nektar Therapeutics and Alkermes Inc. develop powdered insulin.

But Alexza's idea of heating up a drug to create a vapor, or smoke, is unique.

The company's lead product is a vaporized version of an old drug called prochlorperazine, which Alexza is developing for migraine headaches but is currently used in liquid, oral or suppository form to treat severe nausea.

While it is sometimes given intravenously in hospitals to treat patients with acute migraines, the drug is inconvenient to deliver.

HIP FLASK INHALERS

Alexza is hoping to provide similar results but in such a way that patients can carry the delivery device -- an inhaler that looks like a miniature hip flask -- in a pocketbook or the glove compartment of a car.

The device contains a battery-powered package that heats a thin coating of drug to create a vapor that can be sucked into the lungs.

"It's a useful mode of delivery, though its desirability and frequency of prescription will depend on the disorder," said Dr. Jeffrey Lieberman, chairman of psychiatry at Columbia University.

The company plans to release initial results of a mid-stage clinical trial of its migraine drug by the end of March. If all goes according to plan, Alexza could file a marketing application with U.S. regulators in 2010.

The company is also testing inhalable drugs for pain and anxiety, and for agitation in schizophrenia patients.

While Lieberman doubts there would be much demand for an inhaled product for agitated schizophrenia patients, who would be unlikely to cooperate in taking it, he said there could be benefit for patients with migraine, panic and pain.

"People with panic disorder want immediate relief and would be very cooperative," Lieberman said. "They know that if they take a pill it can take up to an hour to work. This would be a non-stigmatizing way to deal with the situation."

Thomas King, Alexza's chief executive, said the company expects to announce a partnership with either a major drugmaker or specialty pharmaceuticals or device company to help develop at least one drug during the second half of this year.

"The key is to find partners with the same passion for the technology and what it conveys as we do," he said.

They are already doing this in Calf with MJ both in leaf form and in a liquid extract form for pain management

A bad idea for opioids. Too rapid acting will lead to euphoria more than pain control.

A small amount, put into cakes or cookies can work very well, and not excessive euphoria, or psychosis. Personally I would be unable to smoke it, it would give too much too quickly.

I have to agree with lobelsteve in regards to opiates. However, there may be some drugs that this type of delivery may be beneficial.

Sounds like a great idea, this is how the connoisseurs smoke their ganga, in a vaporizer..
so I've heard..:D
The DEA would be all over this type of thing, if they intend to make it
for pain control, I'm sure every crackhead on the street will want to try it out.
But is does sound great for that breakthrough pain, when nothing else helps, immediate relief would be good, but I'm afraid could be abused it too easily.
Peace

I am curious, what would be the difference than in making the same painkiller in liguid form, like Morphine? Isn't that very fast acting?

Agree with Dr. Steve and Ragtop.

All I can say is that when I used the Nicotine Inhaler; the one that looks like a cigarette with vapor cartridges, it worked for the cravings but gave me a "head rush". Plus, the vapor or mist stuff caused some burning in my throat. And, no, I wasn't puffing on it like crazy. The cartridges only last for so long anyway. I know, I am a bad girl for smoking...period. But as far as smoking any med goes...no thank you, I will take them in pill, patch or injection form. And why that one guy in the article said that anti-anxiety meds take an hour to kick in is beyond me. Really, I am confused. Sure, we want immediate relief. But I know Xanax kicks in right away...did for me anyway. And Klonopin takes about 20 minutes. I have yet to wait around an hour for something to work.

And the very thing I fight is the euphoria or "head rush" as I put it. I HATE that! All I want is for the pain to be taken care of or at least have the edge taken off. I don't want to be loopy or dizzy. But that's just me. :D Some people may like that feeling, but I just despise it.
