The influence of temperature and relative air humidity on the stability of cefaclor monohydrate in crystalline form and in its pharmaceutical preparations (oral suspension and slow release tablets) was investigated. The process of degradation was studied by using high-performance liquid chromatography with ultraviolet (UV) detection, as described in the monograph of cefaclor in European Pharmac...
BACKGROUND Pharmaceutical companies in Africa need to invest in both facilities and quality management systems to achieve good manufacturing practice (GMP) compliance. Compliance to international GMP standards is important to the attainment of World Health Organization (WHO) prequalification. However, most of the local pharmaceutical manufacturing companies may be deterred from investing in qua...
The pharmacopoeial quality of non-expired and expired nifedipine tablets of the same batches purchased from the Estonian and Russian Federation medicinal product markets was evaluated. The IR spectroscopy, HPLC analysis for quantitative content and purity of the active pharmaceutical ingredient (API), and dissolution test techniques were applied. In the experiments with non-expired nifedipine t...
This learning's objective is to determine and investigate how pharmaceutical restrictions affect the characteristics of gastric floating tablets using diclofenac sodium (DICL) as a model for solubility enhancement, sodium-bicarbonate (NaHCO3) or calcium-carbonate (CaCO3). Hydroxypropyl Methylcellulose (HPMC) swelling polymer K100M K15M gas-forming substance. BY direct-compression manufacturing ...
The applicability of Raman imaging for pharmaceutics production ranges from the characterization pharmaceutical formulations, kinetic processes in drug delivery to rapid detection and identification counterfeit drugs/contaminants. Acetaminophen (Paracetamol, APAP) is an analgesic antipyretic one most consumed medicines worldwide. On other hand, compound 4-aminophenol (4-AP) a hydrolytic product...
A system using energy-dispersive X-ray diffraction (EDXRD) has been developed and tested using multivariate calibration for the quantitative analysis of tablet-form mixtures of common pharmaceutical ingredients. A principal advantage of EDXRD over the more traditional and common angular dispersive X-ray diffraction technique (ADXRD) is the potential of EDXRD to analyse tablets within their pack...
The quality of pharmaceutical products plays an important role in pharmaceutical industry as well as in our lives. Usage of defective tablets can be harmful for patients. In this research we proposed a nondestructive method to identify defective and nondefective tablets using their surface morphology. Three different environmental factors temperature, humidity and moisture are analyzed to evalu...
We propose a general framework for determining optimal relationships for tensile strength of doubly convex tablets under diametrical compression. This approach is based on the observation that tensile strength is directly proportional to the breaking force and inversely proportional to a non-linear function of geometric parameters and materials properties. This generalization reduces to the ana...
chewable ferrous fumarate tablet is the best iron dosage form for children due to better compliance and lower teeth staining compared to the oral drop. because of the different desirable properties of chewable tablets and the opposing effects of fillers on them, the mathematical experimental design was used as the formulation approach. different series of formulations based on single filler (la...
Net analyte signal statistical quality control (NAS-SQC) is a new methodology to perform multivariate product quality monitoring based on the net analyte signal approach. The main advantage of NAS-SQC is that the systematic variation in the product due to the analyte (or property) of interest is separated from the remaining systematic variation due to all other compounds in the matrix. This enh...
