Bixa orellana L., popularly known as "urucum," has been used by indigenous communities in Brazil and other tropical countries for several biological applications, which indicates its potential use as an active ingredient in pharmaceutical products. The aim of this work was to report the main evidence found in the literature, concerning the ethnopharmacology, the biological activity, and the phy...

Levetiracetam is an active pharmaceutical ingredient widely used to treat epilepsy.

The purpose of this study was to investigate the quality of hydroxyprogesterone caproate (HPC) active pharmaceutical ingredient (API) sources that may be used by compounding pharmacies, compared to the FDA-approved source of the API; and to investigate the quality of HPC injection samples obtained from compounding pharmacies in the US, compared to the FDA-approved product (Makena(®)). Samples o...

Crystallization of active pharmaceutical ingredient (API) or pharmaceutical drug substances is a crucial unit operation. In this paper challenges and scientific progress over the last two decades in the areas of pharmaceutical crystallization thermodynamics, kinetics, polymorphism, process modeling, and process control were attempted. Effective utilization of such scientific knowledge for optim...

calibration transfer method is evaluated by transferring multivariate models between two equivalent near-infrared (NIR) analyzers for the prediction of A an Active Pharmaceutical Ingredient (API) in tablets. The method includes selecting a few representative samples, building a transformation relation, and standardizing spectra. Backward and forward transfer approaches are compared. A practical...

Five years ago, we reported the identification and characterization of several regulatory T-cell epitopes (now called Tregitopes) that were discovered in the heavy and light chains of IgG (De Groot et al. Blood, 2008). When added ex vivo to human PBMCs, these Tregitopes activated regulatory T cells (Tregs), increased expression of the transcription factor FoxP3, and induced IL-10 expression in ...

A survey of the multi-stable isotopic composition of an active pharmaceutical ingredient (API), naproxen, was performed to assess the potential of Isotope Ratio Mass Spectrometry (IRMS) to distinguish the provenance of APIs. Twenty-six lots of naproxen from six manufacturers representing four countries (Italy, India, Ireland, and the USA) were analyzed for three isotope ratios (13C/12C, 18O/16O...

The paper presents a dropwise additive manufacturing process for pharmaceutical products (DAMPP) as an alternative to conventional methods. This mini manufacturing process for the production of personalized pharmaceutical products utilizes drop-on-demand (DoD) printing technology for the deposition of active pharmaceutical ingredient (API) onto edible substrates. Here we present a process contr...
