pharmaceutical industry is currently undergoing a transient phase with new orientation. loss of financial resources, presence of new therapeutic agents and increasing cost of research and development have called for a full.scale restructuring within the pharmaceutical industry to retain even the most basic competitiveness. the development of new technologies has been as one way out of the dilem...

Having validated analysis methods for medicinal ingredients is attractive for pharmaceutical companies. When a new molecule is introduced to the market, there is not any pharmacopeial analysis method for that. After publishing official methods, correlation between validated in-house methods and the official one could stablish the value of the in-house method. Sitagliptin phosphate is a new anti...

Dissolution testing measures the rate of drug substance release into solution, impacting the extent of drug absorption. Drug manufacturers and regulatory agencies use dissolution testing to identify drug products that do not meet the desired clinical performance. Formulation composition and manufacturing processes can impact the material attributes of a drug product, which directly affect the d...

The research unit of pharmaceutical analytical chemistry (PAC) has been active in the field of separation sciences for many years. Liquid chromatography (LC) and its latest improvements such as ultra-high performance chromatography (UHPLC) and supercritical fluid chromatography (SFC) are deeply and thoroughly studied, from a fundamental viewpoint to its various application capabilities. Electr...

TERAHERTZ LIGHT Terahertz (THz=10Hz) radiation represents the last unexplored frontier of the radio wave and light spectrum. The so-called ‘Terahertz Gap’ encompasses frequencies invisible to the naked eye in the range from 100GHz (10Hz) up to roughly 30THz (3x10Hz). The former limit lies just above the microwave region, whereas the latter limit is located adjacent to infrared frequencies; the ...

A simple, precise, rapid and low-cost potentiometric method for diclofenac determination in pharmaceuticals is proposed. A new diclofenac-sensitive electrode was constructed by incorporating the diclofenac ion pair complex with butyl rhodamine B into graphite matrix. The electrode exhibited a linear response over the concentration range of 1 × 10-4 – 5 × 10-2 mol L-1, a detection limit of 3.9×1...

in published high performance liquid chromatographic (hplc) methods for analysis of topiramate (tpm) in pharmaceutical dosage forms and raw materials refractive index detector (rid) has been used which is not available in many laboratories and has low sensitivity. we described a new, sensitive and simple hplc method for determination of topiramate in pharmaceutical forms and in-virto dissolutio...

the supply chain represents the critical link between the development of new product and the market in pharmaceutical industry. over the years, improvements made in supply chain operations have focused largely on ways to reduce cost and gain efficiencies in scale. in addition, powerful regulatory and market forces have provided new incentives for pharmaceutical firms to basically rethink the wa...

Pharmaceutical drugs play an important role in human life since they caused a revolution in human health. Notably, their administration to a living organism helps body to stay healthy. Commonly, they are employed to diagnose, prevent, or treat and cure a disease via a biological effect on a human body. Administration of impurity-free and adequate amounts of pharmaceut...
