Atomisation of an aqueous solution for tablet film coating is a complex process with multiple factors determining droplet formation and properties. The importance of droplet size for an efficient process and a high quality final product has been noted in the literature, with smaller droplets reported to produce smoother, more homogenous coatings whilst simultaneously avoiding the risk of damage...

Venlafaxine Hcl is an anti-depressant drug which is used in depression. The aim of present investigation was to prepare an ER tablet of Venlafaxine Hcl with similar dissolution profile matching to Effexor ER. An immediate release core tablet of 100mg was prepared and it was compression coated using HPMC matrix system. HPMC of three viscosity grades i.e., K4M, K15M, K100M and different concentra...

The rapid release from a double-compressed tablet containing theophylline as a core drug with the pH-dependent water-soluble polymers, Eudragit L100, S100 or L100-55 used as a wall material was suppressed by argon plasma-irradiation due to an effect of inter-segmental cross-link reactions on the decrease in the surface polymer solubility of outer layer. In addition, the rapid theophylline relea...

We present CapTUI, an innovative drawing tool that detects tangible drawing instruments on a capacitive multi-touch tablet. There are three core components to the system: the tangible hardware, the recognizer used to identify the tangibles and the drawing software that works in tandem with the tangibles to provide intelligent visual drawing guides. Our recognizable tangible drawing instruments ...

Tablets are the most preferred and widely used dosage form because of their ease of administration, lower cost of manufacture, and elegance. So in this article, we describe the general characteristics, introduction,classification and formulation consideration of compression coating tablet. The compressioncoating granulation or blend can be preformulated to provide desired functionalities to the...

Infty project[1] developed and released some useful software including InftyReader – an OCR system for mathematical documents. InftyEditor is one of the products developed by Infty project, and is a mathematics typesetting tool. The author, a core member of Infty project, built into InftyEditor a computing function for mathematical expressions[2]. In 2003, AsirPad[3], a computer algebra system ...

A new transmission Raman spectrometer has been developed using a spatial heterodyne spectrometer (SHS), taking advantage of the high etendue inherent in this class of spectrometer to maximize the light collected from the target. The system has been tested against paracetamol tablet samples. The instrument has been shown to accept light from 0.05 mm up to a 3 mm core diameter fibre bundle with a...

aluminum phosphide (alp) as 3 g tablet is widely used in iran to protect stored food grains from pests. hyperglycemia following its ingestion has been already reported in the recent years but severe hypoglycemia is uncommon. here, we report a 19 year old male who attempted suicide with one tablet of alp and demonstrated severe hypoglycemia. despite restoration of blood glucose concentration to ...

propranolol, a prototypical b-adrenergic receptor antagonist and atenolol, a cardio-selective b-antagonist are widely used in therapeutic regimens for treatment of hypertensive patients. in iran, several pharmaceutical manufacturers formulate these two b-blockers. as the formulation of a dosage form is essential for the patient's safety and drug efficacy, in this study we aimed to evaluate...

Purpose: To develop a pH-controlled two-pulse drug delivery system of amoxicillin in order to overcome the snag of biological tolerance and to improve bactericidal activity. Methods: The core tablets were compressed and coated with hydroxylpropyl methylcellulose (HPMC) of different viscosities with spray-dried lactose (SDL) as a pore former. The final two-pulse release tablet was prepared with ...
