In spray freeze-srying (SFD), a solution is sprayed into a refrigerant medium, frozen, and subsequently sublimation dried, which allows the production of flowable lyophilized powders. SFD allows commonly freeze-dried active pharmaceutical ingredients (e.g., proteins and peptides) to be delivered using new applications such as needle-free injection and nasal or pulmonary drug delivery. In this study, a droplet stream was injected into a vortex of cold gas in order to reduce the risk of droplet collisions and therefore droplet growth before congelation, which adversely affects the particle size distribution...

Reservoirs located in urban areas suffer specific pressures related to human activities. Their monitoring, management, and protection requirements differ from reservoirs situated in non-urbanized areas. The objectives of this study were: (a) to determine the concentrations of select pesticides and emerging pollutants (EPs) present in an urban reservoir; (b) to describe their possible spatial distributions; and (c) to quantify the risks for aquatic life and safeguard drinking water supplies. For this purpose, the Guarapiranga reservoir was studied as an example of a multi-stressed urban reservoir in a tropical region...

Medicinal plants are being used for treating various diseases. According to World Health Organization 80% of the world population depends on indigenous medicinal plant remedies. Herbal medicine employs fruits, vegetables, as dry materials or their extracts for the treatment of different diseases and health maintenance. Glycyrrhiza glabra (Liquorice) has been used in Europe since prehistoric times. It is well documented in written form starting with the ancient Greeks. Glycyrrhizin is the major active constituent obtained from liquorice roots, one of the most widely used in herbal preparations for the treatment of liver complaints...

The aporia is obvious: food supplement, classified and regulated by food law, sometimes have the characteristics and the typical effects of medicines. In addition, these are produced by pharmaceutical companies and, through the scientific officer, are prescribed by doctors and dispensed by pharmacies. This study will attempt to retrace the winding, and sometimes overlapping, regulatory pathways of the legislation on food supplement, food and medicines. It will be important object the particular application of the precautionary principle behind the legislation on food supplement: application "in posterior", so the controls on the purity of the product and the possible effects resulting from the assumption is carried out ex post trade...

Glioblastoma (GBM) is the most common and most severe form of malignant gliomas. The prognosis is poor with current combinations of pharmaceutical-, radio- and surgical therapy. A continuous search for new treatments has therefore been ongoing for many years. Therapy with tumor-infiltrating lymphocytes (TIL) is a clinically promising strategy to treat various cancers, including GBM. An endovascular intra-arterial injection of TIL as a method of delivery may, instead of intravenous infusion, result in better retention of effector cells within the tumor...

Hot-melt extrusion and 3D printing are enabling manufacturing approaches for patient-centred medicinal products. Hot-melt extrusion is a flexible and continuously operating technique which is a crucial part of a typical processing cycle of printed medicines. In this work we use hot-melt extrusion for manufacturing of medicinal films containing indomethacin (IND) and polycaprolactone (PCL), extruded strands with nitrofurantoin monohydrate (NFMH) and poly (ethylene oxide) (PEO), and feedstocks for 3D printed dosage forms with nitrofurantoin anhydrate (NFAH), hydroxyapatite (HA) and poly (lactic acid) (PLA)...

Pharmaceutical film dosage forms have recently become of interest to pharmaceutical formulation development, particularly for patients who experience difficulty in swallowing tablets or capsules. Furthermore, formulation scientists require a reliable analytical approach to reveal vital insight and investigate the drying process of these films to consolidate suitable quality control. Since most of the polymer-based films containing a drug are produced via solution or dispersion states, an estimation of the physicochemical properties of drugs during drying and dissolution is critical to design novel formulations with the consideration to control drug release, i...

We describe a systematic coarse-graining method to study crystallization and predict possible polymorphs of small organic molecules. In this method, a coarse-grained (CG) force field is obtained by inverse-Boltzmann iteration from the radial distribution function of atomistic simulations of the known crystal. With the force field obtained by this method, we show that CG simulations of the drug phenytoin predict growth of a crystalline slab from a melt of phenytoin, allowing determination of the fastest-growing surface, as well as giving the correct lattice parameters and crystal morphology...

BACKGROUND: Many areas of pharmaceutical legislation in the European Union (EU) are harmonised in order to promote the internal market and protect public health. Ideally, harmonisation leads to less fragmented regulation and cross-border complexities. This study, however, focuses on an increasingly harmonised legislative area that is subject to increases in requirements and complexities: the distribution of medicines. This study compared Danish legislation governing the distribution of medicines before and after Denmark joined the EU in order to assess the impact of EU harmonisation, as well as to evaluate whether the drastic increases in requirements mandated by the Falsified Medicines Directive of 2011 correspond to a new approach to governing the pharmaceutical supply chain...

SUMMARY: The appeal of ketamine - in promptly ameliorating depressive symptoms even in those with non-response - has led to a dramatic increase in its off-label use. Initial promising results await robust corroboration and key questions remain, particularly concerning its long-term administration. It is, therefore, timely to review the opinions of mood disorder experts worldwide pertaining to ketamine's potential as an option for treating depression and provide a synthesis of perspectives - derived from evidence and clinical experience - and to consider strategies for future investigations...

The ability to engineer biocompatible polymers with controllable properties is highly desirable. One such approach is to cross-link carbohydrate polymers using ionotropic gelation (IG). Previous studies have investigated the effect of curing time on alginate cross-linking. Herein, we discuss a novel study detailing the effect of IG residence time (IGRT) on the cross-linking of alginate with calcium ions (Ca(2+)) along with water migration (syneresis) and their subsequent impact on the pharmaceutical properties of alginate particles...

Analogously to the evolution of the EU legislation on pesticides, there is an increasing need of strategies aiming to reach a "sustainable use of veterinary pharmaceuticals". To this end, it is essential to develop tools, such as supporting information systems (SIS), for managing the environmental risks of veterinary pharmaceuticals on a territorial scale. In this context, we propose Sust-PHarm (SUSTainable use of veterinary Pharmaceuticals), a SIS useful to identify groundwater vulnerable areas to veterinary pharmaceuticals at both local and regional scale...
