a new fourier transform-infra red (ft-ir) spectrometric method was developed for assaying hydrochlorothiazide (hct) and enalapril maleate (enm) in binary solid pharmaceutical formulations. multivariate partial least squares (pls) method was used for calibration of derivative spectral data. acetonitrile was used as solvent due to its spectral transparency and adequate solubility of analytes in i...

The effects of magnesium stearate (MgSt) and shear stress on flow properties and hydrophobicity are not well known. Blends with different concentrations of magnesium stearate and varying amounts of shear were tested using three different procedures: the FT4 Rheometer test, a tap density analyzer, and the Washburn method, to better understand the relation of lubricant concentration, amount of sh...

Pharmaceutical formulation development involves various components in addition to the active pharmaceutical ingredients. In recent years, excipient development is become core area of research in pharmaceutical drug delivery because it influences the formulation development and drug delivery process in various ways. Biopolymers are choice of research as excipient because of its low toxicity, bio...

Once discovered and established as therapeutic agent, the drug substance is used for pharmacotherapy of various diseases. The drug substance itself has unique properties, which in certain cases do not allow for effective therapy. This is the area, where pharmaceutical technology allows to improve drug substance original characteristics by optimization of pharmaceutical formulation. The latter i...

background: lidocaine is a local anesthetic and antiarrhythmic agent. there are reports on accidental and intentional cases of poisoning following injection of lidocaine while rare are the fatal cases realized after oral ingestion of lidocaine. suicidal poisoning with lidocaine pharmaceutical formulations is rare since no pharmaceutical dosage forms for oral use are available except gels and sp...
