ABSTRACT

Introduction: Cardiovascular diseases are the leading cause of death worldwide. Objectives: To elucidate the lifestyle of in pharmaceutical company professionals, evaluating cardiovascular risk factors. Methods: This is an observational, longitudinal, and prospective study conducted with 1,875 individuals of both sexes. In addition to a questionnaire to identify participants' lifestyle, calculation of body mass index, blood pressure measurement, and collection of blood samples to measure serum total cholesterol and glycated hemoglobin were performed. Results: 83% of respondents had never smoked; 48.1% did not perform regular physical activity, and women tended to perform less physical activity than men; 57.6% consumed less than two servings of fruits or vegetables per day; 63.8% consumed fish less than once per week; 51.6% consumed less than one glass of sugary drinks per day, with women consuming fewer sugary drinks than men. Most participants had a body mass index from 25 to 29.9 m/kg2 or from 18.5 to 24.9 m/kg2 (43.6%), total cholesterol levels below 200 mg/dL (75.1%), glycated hemoglobin below 5.7% (86.0%), systolic blood pressure from 120 to 139 mmHg (47.6%), and diastolic blood pressure below 80 mmHg (56.1%). Conclusions: The data obtained in this study are consistent with those from the literature, demonstrating that it possible to improve habits such as smoking, diet, and physical activity.


Introdução: As doenças cardiovasculares representam a maior causa de morte em todo o mundo. Objetivos: Elucidar o estilo de vida de profissionais de uma indústria farmacêutica, avaliando os fatores de risco cardiovascular. Métodos: Tratou-se de um estudo observacional, longitudinal e prospectivo, realizado com 1.875 indivíduos de ambos os sexos. Além de questionário para identificar o estilo de vida, foram realizados cálculo do índice de massa corporal, aferição da pressão arterial e coleta de amostra de sangue para dosagem de colesterol total sérico e hemoglobina glicada. Resultados: 83% nunca tinham fumado; 48,1% não faziam atividade física regularmente e mulheres tendiam a realizar menos atividades físicas do que homens; 57,6% consumiam menos de duas porções de frutas ou verduras por dia; 63,8% consumiam peixe menos de uma vez por semana; 51,6% consumiam menos de um copo por dia de bebidas com açúcar, sendo que as mulheres consumiam menos bebidas açucaradas do que homens. A maioria dos participantes apresentou índice de massa corporal entre 25 e 29,9 m/kg2 ou entre 18,5 e 24,9 m/kg2 (43,6%), colesterol total abaixo de 200 mg/dL (75,1%), hemoglobina glicada abaixo de 5,7% (86,0%), pressão arterial sistólica entre 120-139 mmHg (47,6%), e pressão arterial diastólica menor que 80 mmHg (56,1%). Conclusões: Os dados são condizentes com informações de literatura, demonstrando que é possível melhorar hábitos como tabagismo, alimentação e prática de atividade física regularmente.

ABSTRACT

Acidic environments, such as in inflamed tissues, favor the charged form of local anesthetics (LA). Hence, these drugs show less cell permeation and diminished potency. Since the analgesic capsaicin (CAP) triggers opening of the TRPV1 receptor pore, its combination with LAs could result in better uptake and improved anesthesia. We tested the above hypothesis and report here for the first time the analgesia effect of a two-drug combination (LA and CAP) on an inflamed tissue. First, CAP solubility increased up to 20 times with hydroxypropyl-beta-cyclodextrin (HP-ß-CD), as shown by the phase solubility study. The resulting complex (HP-ß-CD-CAP) showed 1:1 stoichiometry and high association constant, according to phase-solubility diagrams and isothermal titration calorimetry data. The inclusion complex formation was also confirmed and characterized by differential scanning calorimetry (DSC), X-ray diffraction, and 1H-NMR. The freeze-dried complex showed physicochemical stability for at least 12 months. To test in vivo performance, we used a pain model based on mouse paw edema. Results showed that 2% mepivacaine injection failed to anesthetize mice inflamed paw, but its combination with complexed CAP resulted in pain control up to 45 min. These promising results encourages deeper research of CAP as an adjuvant for anesthesia in inflamed tissues and cyclodextrin as a solubilizing agent for targeting molecules in drug delivery.

ABSTRACT

Protein drugs present specific challenges to the maintenance of long-term stability, which can be accomplished by altering parameters of obtention, purification, molecule structure and formulation. As we believe, commercial formulations are undervalued; therefore, this review focuses on screening, categorising and discussing all formulations of protein drugs approved and not withdrawn by regulatory agencies from United States, Canada and Europe until mid-2018. Peptides (<50 amino acids) were not included to allow a more precise evaluation of choices for larger molecules. We extracted data from the DrugBank database, cross-checked it with the FDA purple book and supplemented it with patient information leaflets and papers. We further classified and discussed the entries according to protein function, drug delivery, route of administration and types of excipient (freeze-dried forms). In addition, alternative choices of excipients were discussed. Experimental work included here relates to targeting strategies with verified pharmacokinetics or in vivo effectiveness to identify physiologically relevant options. Although no single rule can be set for efficient protein formulation, our data help to better understand and optimise the choice for excipients and pharmaceutical dosage forms. For more information, see the Supplemental Data.

ABSTRACT

Oral route maintains its predominance among the ones used for drug delivery, especially when medicines are self-administered. If the dosage form is solid, therapy gains in dose precision and drug stability. Yet, some active pharmaceutical substances do not present the required solubility, permeability, or release profile for incorporation into traditional matrices. The combination of nanostructured drugs (nanoparticle [NP]) with these matrices is a new and little-explored alternative, which could bring several benefits. Therefore, this review focused on combined delivery systems based on nanostructures to administer drugs by the oral cavity, intended for buccal, sublingual, gastric, or intestinal absorption. We analyzed published NP-in-matrix systems and compared main formulation characteristics, pharmacokinetics, release profiles, and physicochemical stability improvements. The reported formulations are mainly semisolid or solid polymers, with polymeric or lipid NPs and one active pharmaceutical ingredient. Regarding drug specifics, most of them are poorly permeable or greatly metabolized. The few studies with pharmacokinetics showed increased drug bioavailability and, sometimes, a controlled release rate. From our knowledge, the gathered data make up the first focused review of these trendy systems, which we believe will help to gain scientific deepness and future advancements in the field.

ABSTRACT

ABSTRACT The use of biopharmaceuticals dates from the 19th century and within 5-10 years, up to 50% of all drugs in development will be biopharmaceuticals. In the 1980s, the biopharmaceutical industry experienced a significant growth in the production and approval of recombinant proteins such as interferons (IFN α, β, and γ) and growth hormones. The production of biopharmaceuticals, known as bioprocess, involves a wide range of techniques. In this review, we discuss the technology involved in the bioprocess and describe the available strategies and main advances in microbial fermentation and purification process to obtain biopharmaceuticals.
