Hot-melt extrusion is one of the most widely applied processing technologies in the plastic, rubber and food industry. Today this technology has found its place in the array of pharmaceutical manufacturing operations. Melt extrusion process are currently applied in the pharmaceutical field for the manufacture of a variety of dosage forms and formulations such as granules, pellets, tablets, supp...

Drug related problems are an essential term in the world of pharmaceutical care. Other terms can be used for the same concept, such as medication errors, but this term is different from drug related problems. The errors refer to the mistakes in the process that could lead to problems. Drug related problems can originate when prescribing, dispensing or taking/administering medicines. Drug use pr...

In this study a sensitive, simple and accurate spectrophotometric method was suggested for determination of tamsulosin in bulk powder and pharmaceutical dosage form based on the formation of an ion-pair complex between the drug and bromocresol green in a buffer solution at pH 3.5. The formed yellow color complex was extracted with chloroform and measured at 415 nm. The optimum reaction conditio...

Two simple, accurate and precise methods for simultaneous estimation of Esomeprazole and Itopride in bulk drug and tablet dosage form have been described. Method-A employs formation and solving of simultaneous equation using 231 and 370 nm as two analytical wavelengths. Method -B is Absorption ratio method, which uses 308 and 331 nm as two analytical wavelengths.Beer’s law was obeyed in the con...

Fluvoxamine maleate is a selective serotonin reuptake inhibitor, which is used for the treatment of different types of depressive disorders. In the present study, a stability indicating HPLC method was developed and validated for the determination of fluvoxamine maleate. The chromatographic separation was carried out using a Nova-Pak CN column and a mixture of K2HPO4 50 mM (pH 7.0) and acetonit...

Pharmaco-economic evaluations become more important for the reimbursement of pharmaceuticals, and will be obligatory for new pharmaceutical drugs for which an added therapeutic value is claimed and a price premium is proposed by the manufacturer. Therefore, it is important to guide purchasers and providers of pharmaceutical care in their efforts related to the evaluation process. Standard Repor...

Three simple and sensitive visible spectrophotometric methods (A, B, and C) have been developed for the quantitative estimation of mesalamine in bulk drug and pharmaceutical dosage forms. Methods were based on the formation of colored chromogens, which were measured at 552 nm, 440 nm, and 494 nm, respectively. The results obtained with the proposed methods were found to be unsatisfactory with t...

With the increasing interest in polymers of natural origin, the pharmaceutical world has compliance to use most of them in their formulations. Pharmaceutical formulation development involves various components in addition to the active pharmaceutical ingredients. Nature has provided us a wide variety of materials to help improve and sustain the health of all living things either directly or ind...

Implementation of the Quality by Design (QbD) approach in pharmaceutical development has compelled researchers in the pharmaceutical industry to employ Design of Experiments (DoE) as a statistical tool, in product development. Among all DoE techniques, response surface methodology (RSM) is the one most frequently used. Progress of computer science has had an impact on pharmaceutical development...

These are additives used to convert pharmacologically active compounds into pharmaceutical dosage forms suitable for administration to patients [1]. Although excipients are the non-active ingredients, they are essential in the successful production of acceptable solid dosage forms such as tablets and powders. For example, the lack of filling materials would make it exceedingly challenging, if n...
