Spray drying

Abstract Lactose is an excipient used extensively for bulking, diluting, and molding active pharmaceutical ingredients in tablet manufacturing. Particularly, granulated lactose (GL) intended for direct powder compression has distinct properties due to differences in manufacturing methods. It…

ABSTRACT The solid dosage form is the easiest method of administering drugs for systemic effect. All dosages forms are made by two main components one is API and second is excipient. Excipient is present in bulk quantity and is required for binding the API. There are mainly two techniques uses for…

In this work, a spray drying method was developed to produce drug/polymer (simvastatin/polycaprolactone) microparticles that have the potential to be used as a pre-formulation for ex tempore preparation of 2D printing cartridges. An experimental model was designed with the process parameters set to…

In an ideal world, pharmaceutical drugs would have infinite shelf life, no susceptibility to degradation, chemical reactions or loss of efficacy. In reality, these processes occur, however, making it desirable to extend a drugs’ shelf life. Nucleic acid-based drugs are most commonly stored as…

During spray drying, dry powder is circulated into the nozzle zone to force collisions, inducing agglomeration. This study systematically determined the effect of fine powder mass flowrate (varying from 7.1 ± 1.2–15.9 ± 0.5 kg∙h−1), drying air temperature (160–200 °C), and drying air mass flowrate…

During the development of pharmaceutical spray-dried formulations, many samples must be prepared for physico-chemical characterisation and dissolution testing by systematically varying parameters such as drug loading or the grades and ratios of excipients (polymers, surfactants, etc.). When spray…

Introduction Amorphous solid dispersions are state-of the art enabling technique for poorly water soluble active pharmaceutical ingredients (APIs). In an ASD, the API is molecularly dissolved in a suitable polymer matrix that stabilizes the amorphous state during storage against recrystallization…

Abstract Pulmonary delivery of mRNA via inhalation is a very attractive approach for RNA-based therapy for treatment of lung diseases. In this work, we have demonstrated successful development of an mRNA-lipid nanoparticle (LNP) dry powder product (DPP), wherein the LNPs were spray dried using…

Oral multiparticulate systems are often the ‘go to’ solution for flexible dosing, especially in cases where a degree of functionality, such as taste masking or modified release, is required from the formulation. One of the preferred methods of adding functionality to multiparticulates is by fluid…
