Modern polymers in prolonged release tablet technology

Preparation and release study of Levetiracetam 500 mg extended release tablet by using combination of hydrophilic and hydrophobic polymers.

Abstract Levetiracetam as an Anti-epileptic drug with exclusive mechanism of action is accepted by the USA Food and Drug Administration as an adjunctive therapy in treating epilepsy in young adults. The purpose of this project is the design and formulation of prolonged release of levetiracetam using two types of retarding agent such as Hydroxyl Propyl Methylcellulose (HPMC K4...

Formulation of Controlled Release Pelubiprofen Tablet Using Matrix-Forming Polymers

Handicrafts, Encountering Modern Technology

This article aimes to emphasize certain points concerning traditional art , and to put forward a question. As the term” Traditional art” is rather ambiguous, first we try to clarify it. To do so, we propose an approach somehow different from one generally admitted. Thereby, we discuss the reasons why it is not so easy to give a definition of traditional art, islamic art in particular, specially...

Prolonged release matrix tablet of pyridostigmine bromide: formulation and optimization using statistical methods.

The aim of this study was to design and optimize a prolonged release matrix formulation of pyridostigmine bromide, an effective drug in myasthenia gravis and poisoning with nerve gas, using hydrophilic - hydrophobic polymers via D-optimal experimental design. HPMC and carnauba wax as retarding agents as well as tricalcium phosphate were used in matrix formulation and considered as independent v...

Modern Communication Technology and National Security In the Middle East

One of the characteristics of the modern international systems is the undeniable role the new communication technologies play in different sections of human societies. Modern communication technologies such as satellites and computers have challenged the national authority and sovereignty of Vestfallian states.  Although national states, specially, in the third world countries, extremely resist...
