The clinical application of sirolimus (SRL) as an immunosuppressive agent is largely hampered by its narrow therapeutic range. This study focused on developing SRL tablets with a sustained release profile for better safety. SRL was highly water insoluble and its solubility has been efficiently enhanced by preparing self-microemulsifying drug delivery system (SMEDDS). The SRL-SMEDDS was physical...

Aluminum plastic foamed mask package is commonly used for the packaging of tablets in the pharmaceutical companies and defective tablets can be produced during the production of the packaging. This paper studies several key algorithms of defect detection for tablets in aluminum and plastic package and designs the autodetection software which applies an image processing and recognition technolog...

In this study 50 samples of ecstasy tablets seized in Iran during the period of 2007 through 2008 were examined and their physical characteristics (appearance, marking, scored/not scored, color, weight, diameter, thickness) were determined. In order to determine the chemical characteristics of these tablets, color tests (Marquis test, Simon's test, Chen's test and Gallic acid test), Thin Layer ...

PURPOSE The aim of this study was to formulate stable film-coated montelukast sodium (MS) tablets using Opadry(®) yellow 20A82938 (Montikast(®) tablets) and to evaluate their in vitro and in vivo release profile. METHODS MS core tablets were manufactured using a direct compression method. Opadry yellow 20A82938 aqueous coating dispersion was used as the film-coating material. Dissolution of t...

AIMS To provide pharmacodynamic data of crushed and chewed ticagrelor tablets, in comparison with standard integral tablets. METHODS Ninety nine patients with stable angina were randomly assigned, in a 3:1:1 fashion, to one of the following 180mg ticagrelor loading dose (LD) formulations: A) Integral B) Crushed or C) Chewed tablets. Platelet reactivity (PR) was assessed with VerifyNow before,...

SETTING In most developing countries, paediatric tuberculosis is treated with split tablets leading to potential inaccuracy in the dose delivery and drug exposure. There is no data on the quality of first-line drugs content in split fixed-dose combination tablets. OBJECTIVE To determine Isoniazid, Pyrazinamide and Rifampicin content uniformity in split FDC tablets used in the treatment of chi...

The 20 known transforming (onc) genes of retroviruses are defined by sequences that are transduced from cellular genes termed protooncogenes or cellular oncogenes. Based on these sequences, viral onc genes have been postulated to be transduced cellular cancer genes, and proto-onc genes have been postulated to be latent cancer genes that can be activated from within the cell to cause virus-negat...

Protoporphyrinogen oxidase (Protox) inhibitors and other com pounds which block o r stim­ ulate the porphyrin pathway can cause sufficient levels o f porphyrins to accum ulate in plant tissues for severe photodynam ic dam age to occur. The gross sym ptom ology for all o f these p o r­ phyrinogenic herbicides is similar. Porphyrin accum ulation induced by three porphyrinogenic herbicides acifluo...

A few nucleotide sites of nuclear exons that flank introns are often conserved. A hypothesis has suggested that these sites, called "proto-splice sites," are remnants of recognition signals for the insertion of introns in the early evolution of eukaryotic genes. This notion of proto-splice sites has been an important basis for the insertional theory of introns. This hypothesis predicts that the...
