In the present study, the hypolipidemic activity of Piper longum (Family: Piperaceae) fruit extract was studied in two experimental models of hyperlipidemia. In an acute model of hyperlipidemia, induced by injecting a single dose of triton WR-1339 (400 mg/kg, b.w.) intraperitonially in rats, administration of Piper longum extract at the dose of 500 mg/ kg, b.w. resulted in significant lipid loweri...
The threats and risks of the invalid drugs as expired, counterfeit (cheated drugs), Substandard, spurious, falsely labeled, falsified) .The risks and threats of the invalid drugs are many and wide vary, and the countries are trying to prevent these threats by some efforts as the regulatory institution's efforts and the recorded expire date on the drug container, but that are not enough to prevent ...
DRUG DESIGN OF CORTICOTROPHIN RELEASING FACTOR RECEPTOR-1 ANTAGONIST FROM DERIVATIVES OF α ASARONE BY MOLECULAR DOCKING
Stress is one of the most significant health problem in modern society. This paves way for the researchers to focus and investigate into the biological pathways linking stress and health. Hence the goal of the present study is to discover novel drug derivatives from the active principle α asarone of the plant Acorus calamus Linn. (ACL) which was found to have antioxidant &antidepressor effect...
Peptide drugs are poorly absorbable and are also susceptible to enzymatic degradation in the gastrointestinal tract (GIT). To overcome the physiological and morphological barriers for the peptide / poorly absorbable drug delivery, mucopenetrative and mucoadhesive properties of drug carriers have to be considered. Mucoadhesion can prolong the residence time of drug carriers at the absorption sites,...
RAPID, SENSITIVE METHOD FOR THE DETERMINATION OF CINNARIZINE IN PLASMA BY LC-MS/MS AND IT’S APPLICATION TO PHARMACOKINETIC STUDY
Bioavailability of orally administered cinnarizine is typically low and variable due to high incidence of degradation. Many methods are available in public domain for the determination of Cinnarizine in plasma by RP-LC method but none published a LC-MS/MS method. Our objective is to develop a simple, rapid, sensitive bioanalytical method for the determination of Cinnarizine in human plasma by LC-M...
ENHANCEMENT OF DISSOLUTION RATE AND FORMULATION DEVELOPMENT OF RITONAVIR TABLETS EMPLOYING STARCH PHOSPHATE- A NEW MODIFIED STARCH
The objective of the study is to prepare, characterize and evaluate starch phosphate, a new modified starch as a carrier in solid dispersions for enhancing the dissolution rate of ritonavir. The feasibility of formulating solid dispersions of ritonavir in starch phosphate into compressed tablets with enhanced dissolution rate was also investigated. Starch phosphate was prepared by reacting star...
ASSESSMENT OF INTRAPERITONEAL TOXICITY OF X42 FRACTION OF TERMINALIA IVORENSIS (COMBRETACEAE) IN RAT
The present work focuses to check the acute and sub-acute toxicity studies of X42 fraction of Terminalia ivorensis in rats. Materials and methods: The acute toxicity of the extract was evaluated in rats. The rats were administered intraperitoneally the fraction at the dose of 50, 100, 200 and 300 mg/kg bw and recorded general symptoms and mortality. For sub acute toxicity, the rats received intrap...
In the present study anti-inflammatory activity of ethanol extract of Beloperone plumbaginifolia whole plant were investigated. The anti-inflammatory activity of ethanol extract of whole plant of B.plumbaginifolia were evaluated by carageenan induced rat paw edema to determine its effect on acute phase of inflammation models in rats. The phytochemical screening of ethanol extract of whole plant of...
Different plants of the Apocynaceae family viz. Alstonia scholaris, Calotropis procera, Rauvolfia serpentine, Hemidesmus indicus and Calotropis gigantean are traditionally being reported in ulcers treatments. The present study was aimed to validate the authenticity of correlationship of various phytoconstituents concentrations, antioxidant activity and urease inhibitory potential of the same. Vari...
Anxiety is a common and normal phenomenon, involving multiple brain regions, including amygdala, locus ceruleus and frontal cortex. Moreover, multiple brain transmitters regulate the presence and severity of anxiety; these include classical transmitters such as gamma amino butyric acid, serotonin, and dopamine, as well as neuropeptides that include corticotrophin releasing hormone, substance P, ne...
