ABSTRACT

Objectives@#Vitex negundo is an endemic shrub in the Philippines which has been clinically tested for the symptomatic treatment of cough in syrup and tablet formats. However, the effectiveness and safety of the capsule have not been formally documented in a clinical trial setting. Therefore, in compliance with the Philippine FDA directive, this study compared the efficacy and safety of the capsule and tablet formats after three days of treatment among Filipinos with acute uncomplicated cough. @*Methods@#This is a Phase 3b randomized, open-label, parallel-group non-inferiority study with 335 subjects using improvement based on Global Rating of Change Scale scores as primary efficacy endpoint and several secondary endpoints. Descriptive and inferential analyses were performed. The Farrington-Manning Method of Z-test with -10% non-inferiority margin was used for the primary outcome. Appropriate inferential tests were used for the secondary outcomes. @*Results@#Of 335 enrolled subjects, 170 were randomized to the capsule group and 165 to the tablet group with comparable baseline characteristics. The proportion of success based on the Global Rating of Change Scale rated by patients was 95.71% and 91.19% for the capsule and tablet groups, respectively. Based on doctors’ ratings, they were 96.93% and 94.34%, respectively. In addition, the Farrington-Manning Method of Z-test revealed the capsule was not inferior to the tablet based on patients’ and doctors’ ratings (90% Confidence Intervals: -0.0086 to 0.0988 and -0.0228 to 0.0747, respectively). The intention-to-treat analysis also showed non-inferiority, indicating robust results. Significant and similar improvements in cough severity and quality of life were observed in both groups based on Cough Severity Diary scores and Leicester Cough Questionnaire for acute cough, respectively. There were also improvements in the Forced Expiratory Volume at 1 second [FEV1] (capsule group) and Peak Expiratory Flow Rate [PEFR] (both groups), but these were not clinically significant. The safety profiles were also comparable (p= 0.4437) with 1.23% and 2.52% incidence of adverse events, respectively, all of which were mild and assessed as not related to the drug. @*Conclusion@#In terms of efficacy, Ascof® Forte capsule was non-inferior to Ascof® Forte tablet in treating acute uncomplicated cough among Filipinos based on Global Rating of Change Scale scores as rated by patients and doctors. Both treatments showed significant and similar improvements in cough severity and quality of life. They were also comparable in safety with few adverse events in both groups, all mild and assessed unrelated to drug intake.

ABSTRACT

Abstract The phytochemical investigation on Vitex negundo leaves has led to the isolation of one new iridoid glucoside (8α-hydroxy-4-carboxyl-5ßH-9ßH-iridoid-1α-O-(6'-O-(6,7-dihydrofoliamenthonyl)-ß-ᴅ-glucopyranoside, 3), together with three known compounds, namely agnuside (1), 6'-O-E-caffeoylmussaenosidic acid (2), and 3,5-dicaffeoylquinic acid (4). The HPLC analytical study was also performed to quantify the content of agnuside (1) in dried leaves. The results indicated the very high content of 1 (3.04 ± 0.02%). The method was also validated by various parameters, including linearity (R2= 0.9999), precision (intra-day RSD ≤ 2.50%, inter-day RSD= 0.76%), and accuracy (recovery rates 96.58-101.86%). The animal testing data showed that the extract did not reduce pain at the doses of 9.6 and 28.8 g /kg (leaf weight/body weight) in the hot plates and pain measuring models but showed the pain reduction in the acetic acid-induced pain model. The extract at the dose of 5.6 g/kg (leaf weight/body weight) also had effects on the acute inflammation in the carrageenin-induced edema model. The extract at the dose 9.6 and 28.8 g/kg (leaf weight/body weight) also showed significant chronic anti-inflammation, comparable to methylprednisolone at the dose 10 mg/kg on the mouse peritoneal

ABSTRACT

Background: Plants are being used in traditional medicine since history of mankind. The knowledge of these medicinal plants has accrued in the course of many centuries leading to medicinal systems in India such as Ayurveda, Unani and Siddha. Objective: In the present study, we evaluated the anticataleptic efficacy of Vitex negundo, a polyherbal formulation in haloperidol induced catalepsy in mice.Methods: Five groups (n=6) of male albino mice were used in the study. Catalepsy was induced by i.p. administration of haloperidol (1 mg/kg). The degree of catalepsy (cataleptic score) was measured as the time the animal maintained an imposed posture. We compared the anticataleptic efficacy of Vitex negundo (50, 100, 200 mg/kg) with standard received Pheniramine maleate 10 mg/kg, i.p.Results: In vehicle treated animals, haloperidol (1 mg/kg. i.p.) produced the maximum catalepsy at 180 min (46.78�78 min). Standard treated as Pheniramine maleate 10 mg/kg, i.p. shows maximum at 120 min. 19.24�32. Test herb, i.p. Methanolic extract of Vitex negundo (50, 100, 200 mg/kg, i.p.) significantly potentiated haloperidol induced catalepsy at each time interval, in a dose dependent manner. At dose 50, 100 and 200mg/kg, extract of Vitex negundo (Linn.) roots showed maximum cataleptic score 12.34�78, 14.43�43 and 15.43�67 min, respectively at 120 minutes in haloperidol treated animals.Conclusions: The present study indicates that the methanolic extract of Vitex negundo reduces haloperidol-induced catalepsy in mice.

ABSTRACT

Objective: To evaluate a novel polyherbal formulation (BSVT) containing the standardized extracts from the leaves of Boerhavia diffusa, Solidago virgaurea, Vitex negundo, and thymoquinone in CCl4 induced hepatorenal toxicity in rats. Methods: A total of 36 rats were divided into six groups including normal control, CCl4 (2 mL/kg, i.p.), CCl4 (2 mL/kg, i.p.) + Cystone? (750 mg/kg p.o.), CCl4 (2 mL/kg, i.p.) + BSVT (25 mg/kg, p.o.), CCl4 (2 mL/kg, i.p.) + BSVT (50 mg/kg, p.o.), and CCl4 (2 mL/kg, i.p.) + BSVT (100 mg/kg, p.o.). All treatments were given for four weeks. Serum levels of aspartate transaminase, alanine transaminase, alkaline phosphatase, cholesterol, total protein, serum urea, blood urea nitrogen and creatinine were assessed. Superoxide dismutase, malondialdehyde, and glutathione peroxidase were evaluated in tissue homogenate. The histopathological study of liver and kidney tissues was also done. Results: Aspartate transaminase, alanine transaminase, alkaline phosphatase, cholesterol, serum urea, blood urea nitrogen and creatinine were significantly elevated (P<0.001) while total protein was considerably reduced in the CCl4 group as compared to the normal control (P<0.001), which indicated hepatorenal toxicity. In addition, superoxide dismutase and glutathione peroxidase activities were significantly decreased (P<0.001) while malondialdehyde levels were increased markedly (P<0.001). Treatment with BSVT formulation recovered these parameters towards a normal level in a dose-dependent manner. Conclusions: BSVT formulation ameliorates the hepatorenal toxicity in a dose-dependent manner. Furthermore, clinical studies are required to confirm its efficacy.

ABSTRACT

Background: Ulcerative colitis (UC) and Crohn’s disease (CD) are collectively known as inflammatory bowel disease (IBD). Pathophysiology of IBD is not known with certainty. Immunological processes and reactive oxygen species (ROS) have been proposed to contribute considerably to development of tissue injury. Some of the intestinal and/or colonic injury and dysfunction observed in IBD is due to elaboration of these reactive species. Commonly used drugs, in particular sulfasalazine and its active moiety 5-aminosalicylic acid, are potent ROS scavengers. The present study was carried out to evaluate the effect of ethanolic extract of Vitex negundo (EEVN) leaves on experimentally induced inflammatory bowel disease in albino rats.Methods: The rats were divided into four groups of six animals each. Group A and group B received gum acacia per orally, group C received EEVN in dose of 500 mg/kg/day per orally, and group D received 5-amino salicylic acid (5-ASA) in the dose of 100 mg/kg/day per orally. All the animals were pre-treated with respective drugs (volume of drugs was kept constant at 10 ml/kg) for five days, along with the normal diet. On fifth day animals were kept fasting for 12 hours (overnight) and IBD was induced next morning in Groups B, C and D by administration of one ml of 4% acetic acid solution transrectally (TR). Group A (normal control) received 0.9% normal saline transrectally (TR) instead.Results: The results have been shown that EEVN has significant activity against experimentally induced IBD when compared to the experimental control, with near normalization of colon architecture both macroscopically as well as microscopically. Tissue oxidative stress was reduced with significant improvement in tissue levels of superoxide dismutase (SOD) and catalase (CAT). Also, significant improvement in levels of myeloperoxidase (MPO) was observed.Conclusions: It is concluded that ethanolic extract of leaves of Vitex negundo has got potent activity against experimentally induced IBD due to its anti-inflammatory and anti-oxidant properties.

ABSTRACT

Objective@#The aim of this systematic review was to evaluate the efficacy and safety of Vitex negundo (lagundi) for the treatment of acute cough of mild to moderate severity among pediatric patients.@*Methods@#A systematic review of randomized controlled trials (RCTs) comparing lagundi to placebo for acute cough of mild to moderate severity in children and adolescents aged two to twenty one years in ambulatory settings was performed. Authors of unpublished clinical trials with existing patent numbers were contacted and permission was obtained to access and include their studies in this review. @*Results@#Seven studies were included, with a total of 308 participants. Lagundi increased the peak exploratory flow rate (PEFR) at the end of therapy compared with placebo but this was not statistically significant (p=0.36). The increase in PEFR was consistent with the results of the mechanistic isolated tissue studies that showed bronchodilating effect of lagundi. Studies using lagundi syrup showed decrease in the frequency of cough by 44–71%.@*Conclusion@#Lagundi therapy in acute cough of mild to moderate severity among pediatric patients has a bronchodilating effect and decreases the frequency and duration of coughing, with no serious adverse effects.

ABSTRACT

ABSTRACT The objective of the study is to formulate and evaluate a topical herbal gel containing Cardiospermum halicacabum and Vitex negundo leaf extracts for their anti-arthritic activity in rats. Twelve herbal gel formulations were prepared using 1.5% of gelling agents carbopol 934 (F1-F6) and carbopol 940 (F6-F12) and they were evaluated for physical appearance, net content, viscosity, extrudability, pH, spreadability, in vitro diffusion profile and primary skin irritation tests. The stability study for the topical herbal gel formulation was done as per ICH guidelines and anti-arthritic activity was evaluated by Freund's Complete Adjuvant (FCA) induced arthritis method. Assessment of body weight, paw volume, hematological and biochemical parameters, histopathological examination and In vitro determination of serum biomarkers were also carried out. Formulated gels were homogenous, stable and complied with the guidelines. Among the formulations, F4 showed better release (98.4 %) characteristics than other formulations. No erythema or edema was observed in the skin irritation test confirming the gel was non-toxic and safe. Topical application of the herbal gel F4 containing carbopol 934 displayed significant (p < 0.001) anti-arthritic activity compared to diseased rats. Reduction in paw volume, no agglutination in C - reactive protein and rheumatic factor, reduction in TNF level, regaining of normal hematological, and biochemical parameters, reduction in spleen and thymus weight and histopathological examination supported the anti-arthritic activity of the gel formulation.
