Plasticizer

Process analytical technology (PAT) has become an important factor in design, analysis and control of complex technological processes. In the present study, pellet coating process was monitored using four different PAT approaches, i.e. near-infrared (NIR) spectroscopy, Raman spectroscopy, in-line…

Implication of Quantitative Selection of Each Excipient in Product Development Excipients’ role in designing different dosage forms does not require any introduction. These are the additives that are added to the formulation along with pharmacologically active substance. The main purpose of adding…

There a many reasons for coating of different pharmaceutical products such as pellets, granules, capsules, powders and crystals. In this article, we will concentrate on the film-coating of tablets. The procedure of coating tablets is a complex process that results in the forming of a thin layer…

During formulation development, there are cases when, serendipitously, drug or excipients play a different role than intended one or a dual role. One of the examples of a non-traditional role is of a drug acting as a plasticizer. Plasticization tendency of APIs on polymers can be advantageous for…

The purpose of this study was to develop liquid and solid paediatric formulations of sodium dichloroacetate (DCA) for the treatment of congenital lactic acidosis (CLA). In this work preformulation studies on the active molecule were performed to identify those physico-chemical properties of the drug…

We present the design of a novel pH-responsive drug release system that is achieved by solventless encapsulation of drugs within a microporous membrane using a thin capping layer of biodegradable polymethacrylic anhydride (PMAH) coating. The coating was synthesized via a mild vapor polymerization…

Oral modied-release multiparticulate dosage forms, which are also referred to as oral multiple-unit particulate systems, are becoming increasingly popular for oral drug delivery applications. The compaction of polymer-coated multiparticulates into tablets to produce a sustained-release dosage form…

This paper develops a methodology to estimate the break force of curved faced tablets under diametrical compression. Common excipients used in pharmaceutical tablet formulations, including microcrystalline cellulose, calcium phosphate and mannitol as well as their mixtures were characterised.…
