Hydroalcoholic extract of leaves of Arrabidaea brachypoda (DC. ) Bureau present antispasmodic activity mediated through calcium influx blockage

Aim: Since other species of the Bignoniaceae Family presented of antispasmodic activity, it was decided, by chemotaxonomic criterion, to determine the antispasmodic activity of the leaves of Arrabidaea brachypoda. Methodology: the segments of the rat jejunum were suspended in glass vats containing specific saline solution, at an appropriate temperature, and after stabilization period, were stimulated by a contractile agent to observe the inhibitory or relaxing effect of EH-FAB. Results: EH-FAB showed the presence of 10 compounds, mainly rutin and it has an antispasmodic activity as it inhibits the phasic component and relaxes the tonic component of the contraction in isolated rat jejunum. To assess the mechanism of antispasmodic action, cumulative curves to the CCh were performed in which a non-competitive antagonism was observed, due to a displacement of the control curve to the right and reduction of the maximum contraction effect (Emax). Afterward, the participation of the calcium and/or potassium channels was evaluated by increasing the extracellular potassium, and it was observed that the EH-FAB relaxed the rat jejunum, suggesting the participation of the Ca2+ channels. To corroborate that hypothesis, the EH-FAB was tested against cumulative curves to Ca2+ in a free depolarizing solution of Ca2+, and it was observed that there was a shift of the curve to the right with a reduction in Emax. Conclusions: EH-FAB presents antispasmodic activity in isolated rat jejunum and it is suggested to block the influx of Ca2+ through voltage-gated calcium channels, signaling the therapeutic potential for the treatment of colic and/or diarrhea.(AU)

Efficacy of Fenoverine and Trimebutine in the Management of Irritable Bowel Syndrome: Multicenter Randomized Double-blind Non-inferiority Clinical Study / 대한소화기학회지

BACKGROUND/AIMS: Antispasmodic agents have been used in the management of irritable bowel syndrome. However, systematic reviews have come to different conclusions about the efficacy in irritable bowel syndrome. Fenoverine acts as a synchronizer of smooth muscle in modulating the intracellular influx of calcium. We compared fenoverine with trimebutine for the treatment of patients with IBS. METHODS: A multicenter, randomized, double-blind, non-inferiority clinical study was conducted to compared fenoverine with trimebutine. Subjects were randomized to receive either fenoverine (100 mg three times a day) or trimebutine (150 mg three times a day) for 8 weeks. A total of 197 patients were analyzed by the intention-to-treat approach. The primary endpoint was the proportion of patients who had 30% reduction in abdominal pain or discomfort measured by bowel symptom scale (BSS) score at week 8 compared to the baseline. The secondary endpoints were changes of abdominal bloating, diarrhea, constipation, overall and total scores of BSS, and overall satisfaction. RESULTS: At week 8, fenoverine was shown to be non-inferior to trimebutine (treatment difference, 1.76%; 90% CI, -10.30-13.82; p=0.81); 69.23% (54 of 78 patients) of patients taking fenoverine and 67.47% (56 of 83 patients) of patients taking trimebutine showed 30% reduction in abdominal pain or discomfort compared to the baseline. There results of the secondary endpoints were also comparable between the fenoverine group and the trimebutine group. CONCLUSIONS: Fenoverine is non-inferior to trimebutine for treating IBS in terms of both efficacy and tolerability.

CONCLUSIONES Los Probióticos utilizados como suplemento son efectivos en mejorar la sintomatología del SII.

Background: Irritable bowel syndrome (IBS) is a very common functional condition and a frequent cause of consultation in gastroenterology. With a multifactorial pathophysiology IBS is characterized by abdominal pain, distension and altered bowel habits. Loperamide, antispasmodics and antidepressants are symptomatic relievers of this disorder. Recently probiotics were incorporated to therapy, and could improve the symptomatology. Methods: multicenter randomized placebo-controlled trial that included IBS patients, diagnosed with Rome III criteria. The patients were given pinaverium bromure and placebo or pinaverium bromure and probiotics for 3 weeks. The intensity of symptoms and the effect of therapy were evaluated with the Francis Score, before and after the treatment. Statistics were done with SPSS 12.0 (C.I 95%). Results: 51 patients were evaluated, with an average age of 43 years old, mostly mestizo, 75% (38) married and 55% (28) female. There were statistical differences in four variables: abdominal pain, intensity of pain, days of pain and total score at the end of therapy. Conclusions: Probiotics used as supplement are effective in improving symptomatology of IBS.

Guidelines for the Treatment of Irritable Bowel Syndrome / 대한소화기학회지

Traditional symptom-based therapies of irritable bowel syndrome (IBS) are directed at the relief of individual IBS symptoms, but they are often of limited efficacy in addressing the entire symptom complex. Combinations of drugs to target bothersome symptoms are suggested as the first-line pharmacologic treatment. Increasing knowledge of the pathophysiology and molecular mechanisms of IBS has resulted in the development of several new therapeutic approaches. Thirteen consensus statements for the treatment of IBS were developed using the modified Delphi approach. Exclusion diets have modest efficacy in improving symptoms in some IBS patients. Symptom-based therapies with dietary fiber, bulking agents, laxatives, antispasmodics and laxatives are effective in the improvement of some individual symptoms, e.g. dietary fiber and bulking agents for constipation, laxatives for constipation, antispasmodics for abdominal pain and discomfort, antidiarrheals for diarrhea. 5HT3 receptor antagonists and 5HT4 receptor agonists are effective in the relief of global IBS symptoms and individual symptoms such as abdominal pain and abnormal bowel habits. A short term course of nonabsorbable antibiotics may improve global IBS symptoms, particularly in patients with diarrhea- predominant IBS. Some probiotics appear to have the potential benefit in improving global IBS symptoms. Selective C-2 chloride channel activator is more effective than placebo at relieving global IBS symptoms in patients with constipation-predominant IBS. Both tricyclic antidepressants and selective serotonin reuptake inhibitors are equally effective in relieving global IBS symptoms, and have some benefits in treating abdominal pain. Certain types of psychologic therapy may be effective in improving global symptoms in some IBS patients. Further studies are strongly needed to develop better treatment strategies for Korean patients with IBS.

Treatment of Female Urethral Syndrome Refractory to Antibiotics

Various methods of treatment, other than antibiotic therapy, have been proposed for the treatment of female urethral syndrome; however, the results of these treatment methods are disappointing, due perhaps to the use of the wrong treatment approach. The aim of this study was to evaluate the effectiveness of external sphincter relaxant and biofeedback (BFB) with electrical stimulation therapy (EST) in patients who do not respond well to antibiotics. One hundred and five patients with a diagnosis of female urethral syndrome were entered into this study. Antibiotics were given as a first-line therapy for about 3 months. In cases of recurrent or incurable urethral syndrome, antibiotic therapy combined with external sphincter relaxant or BFB with EST were performed. External sphincter relaxant group was composed of 31 patients (29.5%) who showed functional urethral obstruction. Biofeedback group was composed of 41 patients (39.0%) who had severe pain or discomfort with irritative voiding symptoms. Subjective symptom was measured before and after therapy using the Bristol Female Lower Urinary Tract Symptoms questionnaire. Thirty-three patients (31.4%) were treated with antibiotic therapy alone and 7 (21.2%) of these patients recurred. The symptom score of this group changed from 10.51 to 2.85. In the antibiotics plus external sphincter relaxant group (N=31), the symptom score changed from 12.39 to 3.96. Five (16.1%) of these patients recurred and 3 of these 5 underwent urethral dilatation. In the antibiotics plus biofeedback group (N=41), the average urinary frequency changed from 12.2 to 7.7 times a day and nocturia changed from 2.4 to 0.6 times a night. The symptom score improved from 15.22 to 4.69 and the overall satisfaction rate was 87.8% (41.5%: very satisfied, 46.3%: satisfied, 12.2%: no response). Female urethral syndrome is not due to a single factor but is a complex disease due to various combined symptoms and mechanisms. This condition needs to be treated with an appropriate treatment protocol. We believe that satisfactory results could be obtained in female urethral syndrome, which has shown poor prognosis until now, by appropriately combining treatment methods, which include the use of external sphincter relaxants, biofeedback therapy and bladder training, according to indication, and depending on whether symptoms continue after initial antibiotic therapy.

Open labelled evaluation of injection Manyana (a combination of diclofenac + pitofenone + fenpiverinium) in ureteric, biliary and intestinal spasm--a preliminary report.

To study the efficacy and safety of a parenteral formulation of 'Manyana' (a combination of diclofenac + pitofenone + fenpiverinium) in ureteric, biliary and intestinal colic, an open labelled study was conducted at two centres. A total of 206 patients were enrolled and evaluated for decrease in pain with time on a visual analogue scale. A statistically significant difference was observed in pain within 30 minutes of drug administration and the pain relief lasted for as long as 24 hours post dosing. The study shows definite synergism between the antispasmodics pitofenone and fenpiverinium with the NSAID-diclofenac, reducing the prostaglandin levels and also the spasm related to colic.

Double blind, randomised, parallel, prospective, comparative, clinical evaluation of a combination of antispasmodic analgesic Diclofenac + Pitofenone + Fenpiverinium (Manyana vs Analgin + Pitofenone + Fenpiverinium (Baralgan) in biliary, ureteric and intestinal colic.

In this double blind, prospective study, the relative efficacy of Diclofenac + Pitofenone + Fenpiverinium (Manyana) and Analgin + Pitofenone + Fenpiverinium (Baralgan) in 200 patients of biliary, ureteric and intestinal colic was evaluated. Patients were given these coded drugs thrice daily for five days starting from day 0 to day 5. The results of the present clinical evaluation demonstrated that Manyana appeared to be superior to Baralgan in biliary and ureteric colic while it was therapeutically equivalent to Baralgan in reducing the pain intensity in intestinal colic. Both the medications were tolerated well and there were no side-effects reported.
