A randomized, placebo-controlled, double-blind, three-way crossover design was used to evaluate the effectiveness of single oral 100 mg doses of CI-988, a cholecystokinin B (CCKB) antagonist, in attenuating panic symptoms induced by intravenous injection of cholecystokinin-tetrapeptide (CCK-4). Thirty healthy men received the following treatments on three separate occasions: placebo capsules/placebo, placebo capsules/CCK-4, or CI-988 capsules/CCK-4. There was no marked difference in the number, time to onset, or duration of panic symptoms between CI-988/CCK-4 and placebo/CCK-4. There was, however, a 14% difference in sum intensity scores between these treatments that was statistically significant (p = 0.039). The symptoms most affected by CI-988 were cold chills/hot flushes, chest pain/discomfort, and anxiety/fear/apprehension. Panic attack frequency also decreased following CI-988 treatment (8/30 vs. 16/30; p = 0.035). This decrease, amid otherwise modest effects, could be explained by a preferential effect of CI-988 on the subjective experience of anxiety/fear/apprehension. Possible reasons for the relatively modest effects of CI-988 on CCK-4-induced panic symptoms are discussed.

Proton pump inhibitors (PPIs) have revolutionized the treatment of gastro-oesophageal reflux disease (GERD). However, nearly 30% of all GERD patients are still symptomatic despite standard dose PPI treatment. Consequently, better treatment options are needed particularly in nonerosive reflux disease (NERD), which provides the largest number of patients that fail PPI. Transient lower esophageal relaxation (TLESR) is the underlying mechanism for most acid reflux events. Therefore, reducing the rate of TLESRs pharmacologically is an attractive therapeutic approach. Some compounds that were evaluated include: anticholinergics, opioids, cholecystokinin antagonists, nitric oxide antagonists, somatostatin, and GABA-B agonists. Currently, the GABA-B agonist baclofen generated the most promising results. Although data regarding GERD is lacking, visceral pain modulation, either pharmacologically or via mind-body interventions, was found to be efficacious in a variety of functional bowel disorders, including functional chest pain of presumed esophageal origin. Finally, intensive research is currently undergoing to develop newer acid suppressive agents. The acid pump inhibitors are reversible competitive inhibitors of the proton pump. These agents are potent suppressors of gastric acid secretion, and their effect is unrelated to food intake. Moreover, they demonstrate a faster onset of action and a predictable dose response effect as compared to the current PPIs. Although some of the preliminary clinical data is promising, thus far none of these agents is commercially available.
