Prescription drug suicide in non-abusers: A 6-year forensic survey.
CONCLUSIONS: It is reassuring that the absolute number of prescription drug suicides in non-abusers was small; the findings, however, are important because they could serve as a baseline for assessing time trends in future studies. For the present, we suggest that prescription drugs of potential abuse, especially those containing opioids and antispasmodics, should be prescribed and dispensed judiciously, especially to youth.

Dietary modifications for infantile colic.
CONCLUSIONS: Currently, evidence of the effectiveness of dietary modifications for the treatment of infantile colic is sparse and at significant risk of bias. The few available studies had small sample sizes, and most had serious limitations. There were insufficient studies, thus limiting the use of meta-analysis. Benefits reported for hydrolysed formulas were inconsistent.Based on available evidence, we are unable to recommend any intervention. Future studies of single interventions, using clinically significant outcome measures, and appropriate design and power are needed. PMID: 30306546 [PubMed - as supplied by pub...

Dual mechanisms of anti-muscarinic and Ca++ antagonistic activities to validate the folkloric uses of Cyperus niveus Retz. as antispasmodic and antidiarrheal
Conclusion This study shows the presence of antidiarrheal and spasmolytic activities in Cyperus niveus Retz. extract, mediated by dual blocking mechanisms of muscarinic receptors and Ca2+ channels. The results further indicate the presence of anti-emetic activity in Cn. Cr, which may be because of its anti-muscarinic potential. This study provides the scientific bases to the traditional use of Cn. Cr in diarrhea and emesis. Graphical abstract (Source: Journal of Ethnopharmacology)

Differential receptor dependencies: expression and significance of muscarinic M1 receptors in the biology of prostate cancer
This study shows that the type 1 acetylcholine muscarinic receptor (CHRM1) contributes toward the proliferation and growth of prostate cancer. We used growth and cytotoxic assays, the prostate cancer microarray database and CHRM downstream pathways’ homology of CHRM subtypes to uncover multiple signals leading to the growth of prostate cancer. Growth assays showed that pilocarpine stimulates the proliferation of prostate cancer. Moreover, it shows that carbachol exerts an additional agonistic action on nicotinic cholinergic receptor of prostate cancer cells that can be blocked by tubocurarine. With the use of selecti...

The Prokinetic, Laxative, and Antidiarrheal Effects of Morus nigra: Possible Muscarinic, Ca2+ Channel Blocking, and Antimuscarinic Mechanisms
This study demonstrates gut modulatory properties of M. nigra. The prokinetic, laxative, and antidiarrheal activities of M. nigra were assessed in mice, while isolated rabbit jejunum and guinea‐pig ileum were used to explore insight into mechanism(s). At 30 and 70 mg/kg, the crude extract of M. nigra (Mn.Cr) exhibited atropine‐sensitive prokinetic and laxative effects, similar to carbachol (CCh). While at higher doses (100, 300, and 500 mg/kg), Mn.Cr offered protection against castor oil‐induced diarrhea. In rabbit jejunum, Mn.Cr and its chloroform fraction inhibited CCh‐induced c...

Effects of the M1 muscarinic antagonist dicyclomine on emotional memory retrieval.
Extensive research has shown the involvement of the central cholinergic system in the acquisition and consolidation of tasks involving conditioned fear responses, such as those observed in contextual fear conditioning (CFC), tone fear conditioning (TFC) and inhibitory avoidance (IA). However, there are few data concerning the role of this system in the memory retrieval process. Therefore, the present study aimed to compare the effects of the administration of an M1 antagonist on retrieval during these tasks. For each behavioral procedure, groups of male Wistar rats were trained. Twenty-four hr later, they were treated with...

Novel Therapies in IBS-D Treatment
Opinion statement Irritable bowel syndrome (IBS) is a common gastrointestinal disease characterized by abdominal pain and change in bowel habits. IBS diarrhea predominant (IBS-D), which is arguably the most common subset of IBS, is also associated with rectal urgency, increased frequency, abdominal bloating, and loose to watery stools. Current treatments for diarrhea include mu-opioid agonists (i.e., loperamide, lomotil) and bile acid sequestrants (i.e., cholestyramine) while treatments for abdominal pain include antispasmodics (i.e., hyoscyamine, dicyclomine) and tricyclic antidepressants (i.e., amitriptyline).

Infantile Colic: Recognition and Treatment.
Abstract Infantile colic is a benign process in which an infant has paroxysms of inconsolable crying for more than three hours per day, more than three days per week, for longer than three weeks. It affects approximately 10% to 40% of infants worldwide and peaks at around six weeks of age, with symptoms resolving by three to six months of age. The incidence is equal between sexes, and there is no correlation with type of feeding (breast vs. bottle), gestational age, or socioeconomic status. The cause of infantile colic is not known; proposed causes include alterations in fecal microflora, intolerance to cow's milk...

The Charms of the CHRM Receptors: Apoptotic and Amoebicidal effects of Dicyclomine on Acanthamoeba castellanii.
Abstract G-protein coupled receptors (GPCRs) are conserved amongst the eukaryotic cells are known to perform vital functions. Recently, anticholinergic drugs that target muscarinic cholinergic receptors have been found to kill pathogenic protists like Acanthamoeba, Balamuthia mandrillaris and Naegleria fowleri. Because of these effects, it was logical to expect a primeval cholinergic counterpart of this receptor on Acanthamoeba. Bioinformatics searches were made at data banks of Acanthamoeba genome and proteome. Immunostaining was done by using anti-human muscarinic M-1 antibody. Incubation assays were performed u...

Pharmacological justification of use of Solena heterophylla Lour. in gastrointestinal, respiratory and vascular disorders
Conclusions: The observed relaxant effect may be outcome of anti-muscarinic and Ca2+ channel blocking activities. The Sh.Cr (0.03-1.0 mg/ml) against phenyephrine (1 μM)- and K+(80 mM)-induced contractions in isolated rabbit aortic preparations exerted a relaxant effect, possibly through Ca2+ channel blocking activity. These findings provide a rationale for the folkloric uses of the plant in the management of ailments pertaining to gastrointestinal, respiratory and vascular system.

Pharmacological Basis for Medicinal Use of Lens culinaris in Gastrointestinal and Respiratory Disorders
Crude extract of Lens culinaris (Lc.Cr), which tested positive for presence of anthraquinones, flavonoids, saponins, sterol, tannins, and terpenes exhibited protective effect against castor oil‐induced diarrhea in mice at 100–1000 mg/kg. In rabbit jejunum preparations, Lc.Cr caused relaxation of spontaneous contractions at 0.03–5.0 mg/mL. Lc.Cr inhibited carbachol (CCh, 1 μM) and K+ (80 mM)‐induced contractions in a pattern similar to dicyclomine, but different from verapamil and atropine. Lc.Cr shifted the Ca++ concentration‐response curves to the right, like dicyclomine an...

Homeopathy for treatment of irritable bowel syndrome.
CONCLUSIONS: A pooled analysis of two small studies suggests a possible benefit for clinical homeopathy, using the remedy asafoetida, over placebo for people with constipation-predominant IBS. These results should be interpreted with caution due to the low quality of reporting in these trials, high or unknown risk of bias, short-term follow-up, and sparse data. One small study found no statistically difference between individualised homeopathy and usual care (defined as high doses of dicyclomine hydrochloride, faecal bulking agents and diet sheets advising a high fibre diet). No conclusions can be drawn from this study due...

IL-6 attenuates trimethyltin-induced cognitive dysfunction via activation of JAK2/STAT3, M1 mAChR and ERK signaling network.
Abstract We previously reported that interleukin (IL)-6 deficiency potentiates trimethyltin (TMT)-induced convulsive neurotoxicity. The purpose in this study was to investigate the molecular mechanism by which cytokines affect TMT-induced cognitive impairment. To accomplish this, we examined hippocampal changes in Janus kinase 2 (JAK2)/signal transducer and activator of transcription 3 (STAT3) signaling in relation to cholinergic parameters after TMT treatment in mice genetically deficient in IL-6 (IL-6(-/-)), tumor necrosis factor-α (TNF-α(-/-)), or interferon-γ (IFN-γ(-/-)).

Effects of muscarinic agents on chick choroids in intact eyes and eyecups: evidence for a muscarinic mechanism in choroidal thinning
Abstract PurposeIn chicks, ocular growth inhibition is associated with choroidal thickening and growth stimulation with choroidal thinning, suggesting a mechanistic link between the two responses. Because muscarinic antagonists inhibit the development of myopia in animal models by a non‐accommodative mechanism, we tested the hypothesis that agonists would stimulate eye growth and thin the choroid. We also hypothesized that the effective growth‐inhibiting antagonists would thicken the choroid. MethodsChicks, age 12–16 days, were used.
