I have tried Naltrexone .5mg regular and i think the slow release pill would be more effective because it disolve slowly rather than the quick action.I hope to solve the behind the eyes aches i had which i suspect was cause by Nal.

(Nasdaq: PTIE), a biopharmaceutical company, announced its clinical data with PTI-901 is being presented today at the Scientific Meeting of the American College of Gastroenterology in Baltimore, Maryland. PTI-901 is the first in a new class of drugs the Company is developing to treat men or women with irritable bowel syndrome (IBS). Zamir Halpern, M.D., the Head of the Department of Gastroenterology at the Sourasky Medical Center in Israel, and his colleagues will present a clinical poster titled �PTI-901 For The Treatment of Irritable Bowel Syndrome.� Dr. Halpern was Principal Investigator of a previously announced clinical study in which patients with IBS reported a 76% response rate to PTI-901. �Current pharmacological treatments are inadequate for patients with IBS,� said Dr. Halpern. �In this study, PTI-901 provided lasting clinical benefits in patients suffering from chronic IBS. In particular, I am impressed with PTI-901�s ability to improve patients� well-being and to relieve abdominal pain. These clinical improvements were observed in men and women and occurred without drug-related safety issues. Taken together, these clinical data with PTI-901 encourage a large, randomized, placebo controlled study in men and women with IBS.� Pain Therapeutics and the U.S. Food and Drug Administration (FDA) recently met to discuss the Company�s progress with PTI-901. As a direct result of these discussions, the Company plans to initiate a Phase III pivotal program in men and women with IBS in December 2003 in the U.S. -more- 416 Browning Way South San Francisco, CA 9080 4Phone: 650-624-8200 Fax: 650-624-8222 Pain Therapeutics, Inc. October 15, 2003 Page 2 of 3 Study Design and Clinical Results This open-label study was designed to assess the safety and efficacy of PTI-901 in IBS patients. A total of 50 male or female patients, all diagnosed with IBS by a gastroenterologist according to Rome II Criteria, were enrolled in the study. Treatment consisted of a 0.5 mg dose of PTI-901 given daily over a four-week period. Patients were evaluated for global response to treatment, abdominal pain, bowel habits and stool consistency at baseline, in weeks 1 through 4 and during a subsequent four-week follow-up period. The study was conducted by the staff at the Department of Gastroenterology and Liver Disease at the Sourasky Medical Center in Israel, under an Investigational New Drug (IND) Application filed with the FDA by the Company. The efficacy of PTI-901 was assessed in weeks 1 through 4 using the patients� observations of �Global Assessment of Adequacy of Treatment.� The primary endpoint was prospectively defined as patients reporting a weekly global assessment score of fair or better at week 4 compared to baseline. The male and female response rate to the primary endpoint was 77.8% (N=18) and 75% (N=28) respectively. Secondary efficacy endpoints included measurements of abdominal pain and bowel habits. Patients taking PTI-901 reported over 140% increase in number of pain-free days at week 4 compared to baseline (N=42). Clinical improvements in bowel urgency, stool consistency and number of stools per day were also reported at week 4 in both genders. PTI-901 was well tolerated by all patients during the entire treatment period. About PTI-901 PTI-901 (low-dose naltrexone HCI) is Pain Therapeutics� novel drug candidate to treat men or women with IBS. It is believed that an imbalance of opioid activity in the gut contributes to the symptoms that comprise IBS. Such an imbalance may be triggered by emotional stress, metabolic disorders or intrinsic release of opioids from neurons in the gut. PTI-901 is the first in a new class of drugs called opioid antagonists designed to restore the balance of opioid activity in the gut. By restoring this imbalance, PTI-901 relieves abdominal pain and other symptoms frequently observed in patients with IBS. Pain Therapeutics holds exclusive, worldwide commercial rights to a family of issued patents and patent applications directed to the long-term treatment of IBS patients with proprietary opioid antagonists, such as PTI-901. About Irritable Bowel Syndrome IBS is a chronic, painful abdominal disorder that leads to major changes in bowel habits. IBS causes some patients to have constipation, diarrhea or in some cases both. The cause of IBS is not known, and as yet there is no cure. People with chronic IBS may be unable to attend social events, hold a job, or travel away from home. Over 10 percent of the U.S. population suffers from IBS. For unknown reasons, IBS predominantly affects women. About Pain Therapeutics, Inc. We are a biopharmaceutical company specializing in the clinical development of novel painkillers. We believe our unique insights into the biology and biochemistry of pain will allow us to develop new drugs that address unmet needs in pain management. PTI-901 is a small molecule drug to treat IBS. We believe a safe and efficacious drug to treat IBS represents a $1 billion market opportunity. Another drug candidate, Oxytrex�, a small molecule drug to treat severe chronic pain, is currently in Phase III clinical development. Our clinical studies indicate that Oxytrex offers more pain relief with no increase in side-effects, compared to opioid painkillers, such as oxycodone. The market for oxycodone exceeded $1.5 billion in the United States in 2002. For more information, please visit our website at www.paintrials.com. -more- Pain Therapeutics, Inc.

Spas,he's definitely on 5mg, and NOT .5mg. I don't know if its slow release though. they did the trials at a very low dosage and believed 4.5 mg could be optimal as not all symptoms were 100% gone etc. i'm glad to see you are improving. i will start taking ldn when i'm done with my anti-inflammatory.

The list of side effects is scary.I guess they happen more at the regular dose which is 50mg.
I only take a pinch of Nal. by opening the pill.I will trade it for slow-release as they recommand on the low dose nal. web site.Apparently i got head aches but tylenol may help for that.I still try to find a less toxic treatment.
