In vitro study on interaction of ketotifen fumarate with metformin hydrochloride

The present study was designed to study the in vitro interaction of ketotifen fumarate and metformin hydrochloride in aqueous media at different pH values using Job’s continuous-variation analysis and Ardon’s spectrophotomeric measurement. Job’s analysis indicated the formation of 1:1 complex between ketotifen fumarate and metformin hydrochloride at the studied pH values. On the other hand, the values of stability constants (between negative values and 1), as calculated from Ardon’s plot, mean that the formation of complex due to interaction between the drugs is readily dissociable. Thus the findings of the study suggest that both drugs can be safely co-administered. However, further studies involving animal models are needed to ascertain the exact nature of interaction between them in vivo.Colegio de Farmacéuticos de la Provincia de Buenos Aire

IN VIVO AND IN VITRO EVALUATION OF PHARMACOLOGICAL ACTIVITIES OF Hedychium coccineum RHIZOMES EXTRACT

The study reports the in vivo antidiarrheal and in vitro anthelmintic, cytotoxic, and thrombolytic activity of methanol extract of Hedychium coccineum rhizomes (MEHC). The antidiarrheal activity was determined using Castor oil-induced diarrhea and Gastrointestinal motility test in mice at the doses of 200 and 400 mg/kg body weight, whereas an aquarium worm, Tubifex tubifex, was used to determine the anthelmintic activity. The cytotoxic and thrombolytic activity of MEHC was performed by Brine shrimp lethality bioassay and clot lysis method respectively. In antidiarrheal, castor oil-induced diarrhea and gastrointestinal motility exhibited a significant reduction in diarrhea and defecation and an extremely significant inhibition in intestinal motility and peristalsis index by 200 and 400 mg/kg of MEHC. The MEHC (5, 10, and 20 mg/mL) showed a significant dose-dependent manner paralysis time and times to death in multiple comparisons to the different levamisole concentrations (0.5, 0.8, and 1 mg/mL) at in vitro anthelmintic activity. The brine shrimp lethality bioassay exhibited a weak LC50 (681.95 µg/mL; R² = 0.951) while in thrombolytic a significant percentage of clot lysis (32.70%, P < 0.05) demonstrated. The findings demonstrate that H. coccineum rhizomes could be potential sources for biological activity

In Vitro Comparative Cardioprotective Activity of Methanol Extract of Caesalpinia Digyna (Rottl.) Stems and Senna Sophera (L.) Roxb. Stems

The present study was meant to explore the thrombolytic action of methanol extract of Senna sophera stems (MESS) and Caesalpinia digyna stems (MECD) alongside streptokinase as positive control and saline water as negative control. In the In vitro thrombolytic model, the MESS stems and MECD stems has been indicated 32.79±4.51% and 9.19±0.80% clot lysis individually. Between two extracts, MESS stems. has been demonstrated the noteworthy percent of clot lysis (32.79±4.51%) with reference to streptokinase (66.09±2.37%). From our investigation it has been uncovered that between the plants, MESS stems uncovered moderate thrombolytic action. In this way, steps ought to be taken to search in vitro clot dissolving potential and to isolate dynamic segments of MESS Stem for clot lysis are proposed to found. After found, MESS Stem could be recommended as a clot lysis agent in the treatment of patients experiencing disease related with blood clot (Myocardial Infraction, Hypertension, atherosclerosis, Peripheral artery sickness, heart attack and so forth)”

In vitro study on the interaction of ketotifen fumarate with anhydrous theophylline

The purpose of the present study was to investigate the interaction between ketotifen fumarate and anhydrous theophylline in aqueous media of various pH (1.2 and 6.8). Using Job's continuous-variation analysis and Ardon's spectrophotomeric measurement methods, the values of the stability constants of theophylline with ketotifen were determined at a fixed temperature (37 ºC) at various pH. The stability constants, ranging between 5.66 and 9.92, were derived from Ardon's plot, indicating that comparatively stable complexes had formed as a result of an interaction between the drugs. However, following the interaction of theophylline with ketotifen, stability constants were <1 at gastric pH (1.2) and intestinal pH (6.8). Concurrent administration of ketotifen and theophylline could result in the formation of a stable complex and this is likely to reduce the therapeutic activities of both drugs

A study of in-vitro interaction of Ketotifen Fumarate with Domperidone at different gastric and intestinal pH

Aim — The main focus of the project was to identify whether there is any interaction between Ketotifen Fumarate (antihistamine) and domperidone (Antiemetic/dopaminergic antagonist) present or not at simulated gastric and intestinal solutions of different pH. Methods — Using Job’s continuous-variation analysis the possible drug-drug interaction was determined at a fixed temperature (37ºC) at the studied pH. From Job’s continuous-variation analysis the views of drug-drug interaction at different concentration ratio at all pH (0.4, 1.2, 2.0, 2.8, 6.8, and 7.4) except 6.0 were noted. Results — Data obtained from spectroscopic analysis showed decrease in free-drug concentration of both of the drugs analyzed when they were within the same gastric simulated solution. Conclusion — Concurrent administration of Ketotifen Fumarate and domperidone would result in the formation of a stable complex and this is likely to reduce the the rapeutic activities of both drugs

Sedative and Anxiolytic Activities of Geodorum densiflorum Roots in Swiss Albino Mice

Fresh root of Geodorum densiflorum (Lam.) (Orchidaceae) has applications in regularizing menstrual cycle and as topical aids in insect bites and wounds. The tuber extracts of some plants belonging to Geodorum have folkloric reputation in the management of transient anxiety. The current study was undertaken to investigate the sedative/ anxiolytic effects of G. densiflorum root extracts using rodent behavioral models, such as open field, hole cross, thiopental sodium-induced hypnosis and elevated plus maze test. Present data shows that the organic extracts of G. densiflorum root increase the thiopental sodium induced sleeping time and reduce the time for the onset of sleep. A statistically significant reduction in motor activity and exploratory behavior were observed in the open field and hole cross tests. The results of the current studies provide scientific evidence for its uses in traditional medicines as sedative and anxiolytic agents

GC-MS phytochemical profiling, pharmacological properties, and in silico studies of Chukrasia velutina leaves: a novel source for bioactive agents

Chukrasia velutina is a local medicinal plant commonly known as chikrassy in Bangladesh, India, China, and other South Asian countries. The leaves, bark, and seeds are vastly used as herbal medicine for fever and diarrhea, and its leaves essential oils are used for antimicrobial purposes. In this study, we discuss the neuropsychiatric properties of C. velutina leaves through several animal models, quantitative and qualitative phytochemical analysis, and computational approaches. Neuropsychiatric effects were performed in rodents on the methanolic extract of C. velutina leaves (MECVL). Antidepressant, anxiolytic, and sedative effects experimented through these rodent models were used such as the force swimming test (FST), tail suspension test (TST), hole board test (HBT), elevated plus maze test (EPMT), light/dark box test (LDBT), open field test (OFT), and hole cross test (HCT). In these rodent models, 200 and 400 mg/kg doses were used which exhibited a significant result in the force swimming and tail suspension test (p < 0.001) for the antidepressant effect. In the anxiolytic study, the results were significant in the hole board, elevated plus maze, and light/dark box test (p < 0.001) for doses of 200 and 400 mg/kg. The result was also significant in the open field and hole cross test (p < 0.001) for sedative action in the sake of similar doses. Moreover, qualitative and quantitative studies were also performed through phytochemical screening and GC-MS analysis, and fifty-seven phytochemical compounds were found. These compounds were analyzed for pharmacokinetics properties using the SwissADME tool and from them, thirty-five compounds were considered for the molecular docking analysis. These phytoconstituents were docking against the human serotonin receptor, potassium channel receptor, and crystal structure of human beta-receptor, where eight of the compounds showed a good binding affinity towards the respective receptors considered to the reference standard drugs. After all of these analyses, it can be said that the secondary metabolite of C. velutina leaves (MECVL) could be a good source for inhibiting the neuropsychiatric disorders which were found on animal models as well as in computational studies
