The enterochromaffin cells of the gastrointestinal (GI) tract secrete 400 times as much melatonin as the pineal gland; therefore, it is not surprising that research is finding that this indole plays an important role in GI functioning. In animal studies, it protects against GI ulcerations, and randomized clinical trials suggest its efficacy in treating functional dyspepsia and irritable bowel syndrome. Melatonin administration has been shown to protect against esophageal lesions in animals. Moreover, in a randomized, single-blind clinical trial of subjects with gastroesophageal reflux disease (GERD), the combination of melatonin with other natural supplements was found to be superior to omeprazole, a proton pump inhibitor (PPI). Its administration as a single treatment for GERD has not been previously reported. A 64-year-old Caucasian female who required treatment with a PPI for symptoms of GERD wished to substitute a natural treatment because of the risk of worsening her osteoporosis. She experienced a return of symptoms following each of three 20-day trials of a proprietary blend of D-limonene when attempts were made to discontinue the PPI. She then underwent a trial of a natural formula consisting of melatonin 6 mg, 5-hydroxytryptophan 100 mg, D,L-methionine 500 mg, betaine 100 mg, L-taurine 50 mg, riboflavin 1.7 mg, vitamin B6 0.8 mg, folic acid 400 microg, and calcium 50 mg. After 40 days, the PPI was withdrawn without a return of symptoms. Subsequently, an attempt to reduce melatonin to 3 mg resulted in symptoms, while all other ingredients were withdrawn with minimal symptoms during 10 months of follow-up.

Cariprazine (RGH-188, trans-4-{2-[4-(2,3-dichlorophenyl)-piperazine-1-yl]-ethyl}-N,N-dimethylcarbamoyl-cyclohexyl-amine hydrochloride), is a novel antipsychotic with dopamine D2 and D3 receptors antagonist-partial agonist properties. Cariprazine has also moderate affinity for serotonin 5-hydroxytryptophan (5-HT) 1A receptors, high affinity for 5-HT1B receptors with pure antagonism and low affinity for 5-HT2A receptors. Randomized, double blind, placebo controlled, flexible-dose (3-12 mg/day) studies have demonstrated cariprazine is effective in both schizophrenia and acute manic episodes associated with bipolar disorder. The incidence of serious adverse events in cariprazine arm was no different than in placebo arm in these studies. The most common adverse events were extrapyramidal symptoms, headache, akathisia, constipation, nausea, and dyspepsia which can be explained with cariprazine's partial dopamine agonism. Although cariprazine treatment was associated with a higher incidence of treatment-emergent adverse events, particularly akathisia and tremor, common side effects of marketed second generation antipsychotics such as weight gain, metabolic disturbances, prolactin increase or QTc prolongation were not associated with cariprazine, probably due to its moderate to low binding affinity for histamine H1 and 5-HT2C receptors. Animal studies show that cariprazine may have additional therapeutic benefit on impaired cognitive functioning with D3 receptor activity, however clinical data is still scarce. The aim of this article is to review the potential use of cariprazine for the treatment of acute manic episodes in the light of the preclinical and clinical trials reported to date.
