Summary of "Development and validation of a green method for dissolution monitoring of pharmaceutical combinations. Meloxican and pridinol."

The development of a chemometric method for monitoring the pharmaceutical dissolution, under green analytical chemistry principles, was reported. Meloxicam (MEL) and pridinol (PRI) were employed as a combination model. Multivariate curve resolution with alternating least squares (MCR-ALS) was proposed to resolve UV spectra of the analytes during pharmaceutical dissolution. Empowering UV-vis spectrophotometry, which is considered an economical, ecological and fast technique, but poor in terms of selectivity. The developed method was validated in accordance to ICH guidelines, fulfilling acceptance criteria for linearity (r > 0.99 in the ranges 3.5-19.6 mg L and 0.81-5.41 mg L for MEL and PRI, respectively), accuracy (96.3% and 100.6% recoveries for MEL and PRI respectively), and precision (RSD < 10%) were evaluated using an independent validation set. Using a commercial sample, the method's accuracy was evaluated against HPLC analysis. Dissolution profiles were obtained using both methods. A point-to-point comparison with Moore and Flanner's factors (f and f) were calculated. Specificity was evaluated by spectral correlation (R>0.950). Additionally, the developed method works on-line and forgoes organic solvents and dilutions, lending itself to automation.

Method of tissue preparation in which the tissue specimen is frozen and then dehydrated at low temperature in a high vacuum. This method is also used for dehydrating pharmaceutical and food products.

Economic aspects of the fields of pharmacy and pharmacology as they apply to the development and study of medical economics in rational drug therapy and the impact of pharmaceuticals on the cost of medical care. Pharmaceutical economics also includes the economic considerations of the pharmaceutical care delivery system and in drug prescribing, particularly of cost-benefit values.

Algae of the division Chlorophyta, in which the green pigment of CHLOROPHYLL is not masked by other pigments. Green algae have over 7000 species and live in a variety of primarily aquatic habitats. Only about ten percent are marine species, most live in freshwater. They are more closely related to the green vascular land PLANTS than any other group of algae.
