Trimeprazine is enantioselectively degraded by an activated sludge in ready biodegradability test conditions
2018
[EN] A great number of available pharmaceuticals are chiral compounds. Although they are usually manufactured as racemic mixtures, they can be enantioselectively biodegraded as a result of microbial processes. In this paper, a biodegradability assay in similar conditions to those recommended in OECD tests of enantiomers of trimeprazine (a phenothiazine employed as a racemate) is carried out. Experiments were performed in batch mode using a minimal salts medium inoculated with an activated sludge (collected from a Valencian Waste Water Treatment Plant, WWTP) and supplemented with the racemate. The concentration of the enantiomers of trimeprazine were monitored by means of a chiral HPLC metho…
The future: critical knowledge about anti-itch therapy.
2005
: Itch is an extremely frequent and enervating symptom of many diseases. Current anti-itch therapy, which is based almost exclusively on an “immunocentric” viewpoint, is often unsatisfactory. Recent studies show that this symptom is in fact the result of a complex interplay among skin, nervous system, endocrine system, and immune system. This explains the frequent failure of therapeutic strategies focused only on a single factor and suggests the usefulness of a polypharmacologic symptomatic treatment, designed on a case-by-case basis as a result of a multidisciplinary approach. We discuss the perspectives of anti-itch therapy in light of the new pathogenetic and pharmacologic acquisitions.
Pruritic and antipruritic colors: An exploratory pilot study.
2020
Itch is the commonest skin-related symptom and can be influenced by visual cues as exemplified by the phenomenon of "contagious itch." Colors are visual cues able to modify somatosensory inputs. We explored the relationship of colors and itch and the impact of color viewing on itch intensity. In this cross-sectional study, patients suffering from itch with a mean intensity of ≥2 on a Numerical Rating Scale during the last 7 days were evaluated. The study consisted of a questionnaire-based part using The Manchester Color Wheel and the ItchyQoL, followed by an interventional part. All 72 itch patients were able to match their itchy sensation with a color: In 68 patients (94.4%) this "pruritic…
