title: Optimization of cosmetic formulations development using Box-Behnken design with response surface methodology: physical, sensory and moisturizing properties

description: Considering the importance of an adequate composition of the formulation in the development of stable, safe and effective cosmetic products, experimental design techniques are tools that can optimize the formulation development process. The objective of this study was to develop topical formulations using the Box-Behnken design with response surface methodology and evaluate its physical, sensory and moisturizing properties. The experimental design used in the first step allowed to identify and to quantify the influence of raw materials, as well as the interaction between them. In the second step, the analysis identified the influence of soy lecithin, the phytantriol and capric acid triglyceride and caprylic on the consistency index, stickiness and greasiness and skin hydration. Cetearyl alcohol, dicetyl phosphate and cetyl phosphate 10EO and acrylates/C10-30 alkylacrylate crosspolymer showed effects in rheological parameters. The addition of soy lecithin had significant effects in terms of consistency index, stickiness, oiliness and immediate moisturizing effects. Phytantriol showed effects on increasing consistency index and oiliness sensation. Thus, the experimental design was shown to be an effective tool for research and development of cosmetics, since it allowed the assessment of the individual and interaction effects of raw materials in the responses: rheological parameters, sensory and clinical efficacy.

title: Preparation and characterization of liposomes loaded with silver nanoparticles obtained by green synthesis

description: The objective of this work was to develop and characterize liposomes loaded with silver nanoparticles (LAgNPs) to show improvement in stability characteristics. AgNPs were prepared by the green synthesis method with Aloe vera gel extract and exposure to sunlight. Liposomes were prepared by the modified reverse phase method. Particle size, polydispersity index, zeta potential, as well as the scanning electron microscopy (SEM) morphological aspects of AgNPs and LAgNPs were evaluated. In addition, was used flame atomic absorption spectroscopy to determine the amount of AgNP that was encapsulated in liposomes. The AgNPs presented as amorphous and polydisperse structures, with a mean diameter of 278.46 nm and zeta potential of -18.3 mV. LAgNPs had a mean diameter between 321 and 373 nm, the polydispersity index close to 0.2 and a zeta potential around -40 mV, which indicates greater stability to the AgNPs. The images obtained by SEM show semicircular structures for AgNPs and well-defined spherical shape for LAgNPs. The percentage of encapsulation was between 51.81 to 58.83%. These results showed that LAgNPs were obtained with adequate physicochemical characteristics as a release system.

title: Safe-by-design development of a topical patch for drug delivery

description: Few topical products have been developed specifically to treat acute and chronic arthritis and inflammation, using non-steroidal anti-inflammatory drugs (NSAIDs). The lack of dosing accuracy commonly found in locally applied semisolid products for cutaneous use is a critical issue that leads to treatment failure. The aim of the present work is to develop a differentiated and innovative topical patch based on a monolithic hydrogel for ibuprofen skin delivery, in order to provide a safer and accurate way of drug administration along with improved treatment compliance. Topical patches based on hydroxypropylmethylcellulose (HPMC) were optimized in composition, in terms of enhancer and adhesive, supported on a systematic assessment of in vitro release and permeation behavior and adhesion properties. Several mathematical models were used to scrutinize the release mechanisms from the patches. In vitro release kinetics was shown to be mainly driven by diffusion. However, other mechanisms seemed to be also present, supporting the feasibility of using patches for sustained drug delivery. PEG 200 provided the best permeation rate, with a permeation enhancement ratio of ca. 3 times higher, than the commercial reference. The addition of Eudragit L30D 55 to the formulation led to the best adhesion profile, thus achieving a successful development based on a safe-by-design concept.

title: Validation of a method for simultaneous analysis of cocaine, benzoylecognine and cocaethylene in urine using gas chromatography-mass spectrometry

description: Abstract The present study describes a method for simultaneous analysis of cocaine, benzoylecgonine and cocaethylene in urine samples. After solid phase extraction, Gas Chromatography-Mass Spectrometry was used for identification and quantification. The calibration curves were linear at 20 - 3000 ng/mL, r2 0.9997 for benzoylecgonine, 15 - 2000 ng/mL, r2 0.9985 and r2 0.9993 for cocaine and cocaethylene, respectively. Accuracy values: cocaine: 93,5 - 102,1%; benzoylecgonine: 97,5 - 104,8%; cocaethylene: 90,6 - 101,5%. Precision values: cocaine: C.V 5,4 - 14,6%; benzoylecgonine: C.V 7,8 - 12,3%; cocaethylene: C.V 5,9 - 12,3%. Detection and quantification limit values: cocaine and cocaethylene:10 ng/mL and 15 ng/mL, respectivalty; benzoylecgonine:15 ng/mL and 20 ng/mL, respectivaley. Recovery values: cocaine: 78,0 - 85,8%; benzoylecgonine: 74,0 - 79,8%; cocaethylene: 83,0 - 91,5%. The method described is advantageous compared to others, as it simultaneously detects the major analytes found in urine samples due to cocaine use and has been successfully validated.

title: Pharmacovigilance of thalidomide in the Brazilian Health System and patient safety

description: In Brazil, thalidomide is manufactured by a public laboratory, distributed by the Unified Health System (SUS), and regulated by the National Health Surveillance Agency (Anvisa). Despite the concerns regarding the adverse effects of thalidomide, few drug utilization studies have been conducted to describe processes and outcomes related to this drug. The aim of this study was to elucidate the issues related to the utilization and control of thalidomide, and patient safety within the scope of SUS. In this cross-sectional study, we evaluated the articulation between an outpatient dermatology service of a referral hospital in infectology, the manufacturer, and Anvisa. Four data sources were used: i) interviews with health professionals; ii) data from the Customer Service of the manufacturer, iii) data on adverse events reported to Anvisa, and iv) adverse events identified in outpatient service. Most health professionals interviewed knew the major thalidomide-related adverse effects. None of them ever reported adverse events to Anvisa or contacted the Customer Service. For over three years, there were 330 calls concerning thalidomide at Customer Service, 7% of which were related to adverse events. During a period of six years, Anvisa was notified of only 15 adverse events. Health professionals were aware of the adverse events associated with thalidomide, but not the necessity to report them. The low number of notifications recorded by Anvisa and the information obtained from Customer Service show that pharmacovigilance remains incipient. A pharmacovigilance system that integrates all the services associated with thalidomide is required to strengthen this activity within the SUS to improve patient safety.
