Spray drying
Review of industrially recognized polymers and manufacturing processes for amorphous solid…
Evolving therapeutic landscape through combinatorial chemistry and high throughput screening have resulted in an increased number of poorly soluble drugs. Drug delivery strategies quickly adapted to convert these drugs into successful therapies. Amorphous solid dispersion (ASD) technology is widely…

Evaluating spray gelation and spray freeze drying as the granulation method to prepare oral tablets…
Amorphous drug nanoplex represents one of the most promising solubility enhancement strategies of poorly-soluble drugs. Solubility enhancement capability of nanoplex hitherto has been demonstrated for nanoplex suspension and lyophilized/spray-dried nanoplex, but not for its oral tablets. Using…

Lactose in tablets: functionality, critical material attributes, applications, modifications and…
Abstract
Lactose is one of the most widespread excipients used in the pharmaceutical industry. Because of its water solubility and acceptable flowability, lactose is generally added into tablet formulation to improve wettability and undesirable flowability. Based on quality by design, a better…

Spray Dried Progesterone Formulations for Carrier Free Dry Powder Inhalation
Low oral absorption and extensive first pass metabolism of progesterone is reported for many oral formulations which warrants investigation into other routes of administration. It is the aim of this study to investigate the generation of inhaled formulations of progesterone though a spray drying…

Lipid-based particle engineering via spray-drying for targeted delivery of antibiotics to the lung
Pulmonary delivery of antibiotics for the treatment of tuberculosis provides several benefits compared to conventional oral and parenteral administration. API-loaded particles delivered directly to alveolar macrophages, where Mycobacterium tuberculosis resides, can reduce the required dose and…

Effect of batch-to-batch variation of spray dried lactose on the performance of feeders
With the emergence of quality by design (QbD), it becomes imperative to gain understanding of the impact of batch-to-batch variability of raw materials on the performance of processes. Feeding is the first unit of operation in a continuous manufacturing line and is critical for the final product…

Can the Oral Bioavailability of the Discontinued Prostate Cancer Drug Galeterone Be Improved by…
Galeterone, a novel prostate cancer candidate treatment, was discontinued after a Phase III clinical trial due to lack of efficacy. Galeterone is weakly basic and exhibits low solubility in biorelevant media (i.e., ~ 2 µg/mL in fasted simulated intestinal fluid). It was formulated as a 50–50 (w/w)…

Engineering artesunate-loaded micelles using spray drying for pulmonary drug delivery
Novel d-α-tocopheryl polyethylene glycol 1000 succinate (TPGS) micelles containing the anti-cancer drug artesunate (ART) were developed in a dry powder form for inhalation for the treatment of lung cancer. Targeted delivery to the lungs via inhalation presents a challenge, and the current study…

A multi-step machine learning approach for accelerating QbD-based process development of protein…
This study proposes a new material-efficient multi-step machine learning (ML) approach for the development of a design space (DS) for spray drying proteins. Typically, a DS is developed by performing a design of experiments (DoE) with the spray dryer and the protein of interest, followed by deriving…

Comprehensive powder flow characterization with reduced testing
Powder flow is a critical attribute of pharmaceutical blends to ensure tablet weight uniformity and production of tablets with consistent and reproducible properties. This study aims at characterizing different powder blends with a number of different rheologic techniques, in order to understand how…
