Evaluation of Phyto-Chemical and Medicinal Properties of Cannabis Sativa Linn. (Family Moraceae).

Abstract This work studied the various delivery systems (oral and parental formulations) of crude Cannabis. The stability, pharmacological and toxicological profiles of Cannabis resin in the formulations was also studied. Dried powdered leaves of Cannabis sativa L. were extracted with chloroform, the extract was concentrated to obtain an oil-based tar (resin) and its phytochemical composition determined. The Cannabis crude resin was formulated as syrup, capsule and suppository dosage forms. ...

Solid Dispersions Based on Peg 4000, Soluplus and their Hybrids for Enhanced Delivery of Glimepiride

ABSTRACT The present study investigates the possibility of enhancing the solubility, and hence the bioavailability of poorly water soluble glimepiride via formation of polyethylene glycolpolyvinyl caprolactam - polyvinyl acetate grafted copolymer (Soluplus®) and PEG 4000 based solid dispersions by solvent evaporation technique.Different batches of glimepiride solid dispersions (SD) were prepared using solvent evaporation method with Soluplus® and PEG 4000 as polymer matrix at different rat...

Protective Role of Aqueous Leaf Extract of Vernonia Amygdalina Del. (Asteraceae) And Ocimum Gratissimum Linn (Lamiaceae) in Cyclophosphamide Induced Urotoxicity and Myelosuppression

ABSTRACT Cyclophosphamide (CP) is one of the most potent and widely used alkylating anticancer agents. Urotoxicity and myelosuppression is known as the most prevailing dose-limiting toxicity associated with CP. In the present study, the protective potential of Vernonia amygdalina and Ocimum gratissimum aqueous leaf extracts in CP-induced urotoxicity and myelosupression were evaluated using biochemical and histopathological approaches. Sodium -2-macarptoethane sulfonate (MESNA) was used as a p...

Antidiabetic Potentials of Lipospheres Encapsulating Anogeissus Leiocarpus Dc Guill & Perr Root Bark Methanol Extract

ABSTRACT The study was aimed at evaluating the antidiabetic potentials of Anogeissius leiocarpus DC Guill and Perr root bark methanol, ethanol and ethanol plus trona extract; and preparing, characterizing and evaluating lipospheres as drug delivery system loaded with A.leiocarpus root bark methanol extract. 400 mg/kg of methanol,ethanol and ethanol plus trona extracts of the A.leiocarpus root bark extracts were used in preliminary evaluation of antidiabetic effect of this plant root bark extr...

Evaluation of N- Hydroxymethyl Chlorphensin Carbamate and Ethionamide as Potential Prodrugs

ABSTRACT Chlorphensin carbamate is a centrally acting muscle relaxant, insoluble in water, readily absorbed from the gastro-inteatinal tract, when administered orally and highly metabolished. The mechanism of action is by depressing spinal polysynaptic reflexes. Neuronal conduction, neuromuscular transmission and muscle excitability are not depressed except after nearly lethal doses. This action led to its characterisation as inter-neuronal blocking agent and therefore used to relief symptoma...

Bioactivity-Guided Studies on the Crude Extract and fractions of Hibiscus Asper Hook F. (Malvaceae) Leaf

ABSTRACT The antibacterial and anti-inflammatory activities of the leaf extract of Hibiscus asper Hook F. (Malvaceae) were investigated. Solvent extraction of the leaves yielded the crude methanol extract (CME), while solvent-guided fractionation of CME yielded a n-hexane fraction (HF), chloroform fraction (CF), ethyl acetate fraction (EF), acetone fraction (AF), butanol fraction (BF), methanol fraction (MF) and water fraction (WF). TheCME and the solvent fractions were subjected to phytochem...

Predicting Intestinal Permeation of Drugs Through Neural Network Analysis Based on Five Molecular Descriptors

ABSTRACT The oral route is generally preferred for drug administration because of its ease and good patient compliance. In the search for new drugs for oral administration a major problem encountered is obtaining drug structures which, as well as being potent in viiro, possess favourable pharmacokinetic profiles which enable them to pass easily through the relevant body membranes, especially the gastrointestinal epithelia to effect their action. However, many of the compounds derived from com...

Assessment Of The Pharmaceutical Manufacturing Industry In Kenya To Forecast Local Production Sufficiency

ABSTRACT The World Health Organization’s global strategy on public health aims to support Member States to improve access to essential medicines. The desire of Kenya Government to implement this is expressed by formulation of Kenya National Pharmaceutical Policy (2010) which encourages local production of essential medicines for self-sufficiency. The pharmaceutical manufacturing industry in Kenya is engaged in production of various types of dosage forms but its capacity and capability to p...

Antimicrobial And Wound Healing Properties Of Leaf Extracts, Fractions And Ointment Formulations Of Spermacoce Verticillata Linn (Family: Rubiaceae)

ABSTRACT This study investigated the antimicrobial and wound healing properties of leaf extracts and ointment formulations of Spermacoce verticillata Linn (Family: Rubiaceae). Three different solvents: acetone, ethanol and water were used in the extraction of phytochemicals from the leaves of Spermacoce verticillata. The bioactive constituents of acetone, aqueous and ethanol extracts were determined using standard phytochemical analytical methods. The cup plate agar diffusion method was ...
