this study presents the synthesis of polyvinyl acetate (pvac) by solution polymerization and its partial hydrolysis to polyvinyl alcohol (pva) using alkaline alcoholysis. the influence of the molar ratio of hydrolysis catalyst (naoh) to pvac and the time and temperature of the saponification reaction on the degree of hydrolysis and molecular weight of the pva were investigated using response su...

The purpose of this study is to evaluate the use of arabinoxylan as potential suspending agent, an effective alternative to commercially used excipients for the preparation of pharmaceutical suspensions. Alkali extraction was done to separate arabinoxylan from ispaghula (Plantago ovata) seed husk by alkali extraction its physicochemical characterization was done and the suspending properties of...

Suspensions are one of the most important dosage forms under liquid orals. A large number of drugs are formulated as suspensions considering their therapeutic and commercial benefits. The aim of the present study is to formulate paracetamol suspensions employing Plantago ovata mucilage as a suspending agent and evaluate the sedimentation stability using near infrared transmission measurements. ...

The present study was undertaken to evaluate the mucilage isolated from Cissus vitiginea, commonly known as ‘Virginia snakeroot’ (FamilyVitaceae) as an innovative suspending agent. The purpose of this study is to search for a natural excipient which is cost effective that can be used as an alternative for the formulation of pharmaceutical suspensions. Characterization studies like solubility, s...

Intelligent agents designed to work in complex, dynamic environments must respond robustly and flexibly to environmental and circumstantial changes. An agent must be capable of deliberating about appropriate courses of action, which may include reprioritising goals, aborting particular tasks, or scheduling tasks in a particular order. This paper investigates the incorporation of a mechanism to ...

Some excipients are currently available for the formulation of Pharmaceutical suspensions. The purpose of this study is to search for a cheap and effective natural excipient that can be used as an effective alternative for the formulation of pharmaceutical suspensions. The mucilage from the pods of Abelmoschus esculentus was subjected to preformulation study for evaluation of its safety and sui...
