RESUMO Objetivo: Analisar o perfil dos medicamentos cardiovasculares manipulados prescritos em neonatologia no Brasil. Fontes de dados: Foi realizada uma revisão bibliográfica integrativa, incluindo estudos publicados nos últimos 20 anos. As palavras-chave utilizadas foram: intensive care neonatal, off-label use, pharmaceutical preparations, nos bancos de dados da Biblioteca Virtual em Saúde (BVS), PubMed e Biblioteca Eletrônica Científica Online (SciELO). Os artigos de revisão e diretrizes foram excluídos. A qualidade da evidência foi analisada, e foram selecionados 10 artigos para integrar o estudo. Síntese dos dados: Todos os estudos possibilitaram a avaliação do perfil de prescrição na rotina da unidade. Os principais fármacos cardiovasculares, prescritos em formulação extemporânea, foram espironolactona, captopril, furosemida, hidroclorotiazida, propranolol, amiodarona, nifedipina, carvedilol, digoxina, enalapril, epinefrina e hidralazina. Os medicamentos foram obtidos mediante adaptações de formas farmacêuticas, por meio da transformação de cápsulas ou comprimidos em formulações líquidas, como solução, suspensão ou xarope, assim como também na forma de soluções preparadas com base nos insumos farmacêuticos ativos. A manipulação de medicamentos tornou possível o tratamento medicamentoso em neonatologia, uma vez que tais medicamentos não possuem registro da forma farmacêutica líquida oral no país, apesar de integrarem a lista de medicamentos essenciais em pediatria da Organização Mundial da Saúde. Conclusões: Foi possível analisar o perfil dos medicamentos cardiovasculares manipulados prescritos na neonatologia no Brasil. Os resultados evidenciaram a necessidade do desenvolvimento de medicamentos adequados à população neonatal e à padronização dos procedimentos operacionais do preparo de formulações extemporâneas na neonatologia, para aumentar a segurança dos medicamentos.

ABSTRACT Objective: To analyze the profile of the compounded cardiovascular medicines prescribed in neonatology in Brazil. Data source: An integrative bibliographic review was carried out, including studies published in the last 20 years. The used descriptors were: Intensive Care Neonatal, Off-Label Use, Pharmaceutical Preparations, in the databases Virtual Health Library (VHL), PubMed, and Scientific Electronic Library Online (SciELO). Review articles and guidelines were excluded. The quality of the evidence was analyzed, and 10 articles were selected to integrate the study. Data synthesis: The profile of routine prescrption in the neonatal unit was evaluated. The main cardiovascular medications prescribed as compounding formulation were: Spironolactone, Captopril, Furosemide, Hydrochlorothiazide, Propranolol, Amiodarone, Nifedipine, Carvedilol, Digoxin, Enalapril, Epinephrine, and Hydralazine. The drugs were obtained from adaptations of dosage forms, through the transformation of capsules or tablets into liquid formulations, as a solution, suspension, or syrup, as well as in the form of solutions prepared from active pharmaceutical ingredients. The compounding of medications made drug therapy possible in neonatology, considering that such medications do not have registration of the oral liquid dosage form in the country, despite being part of the List of Essential Medicines for Children of the Word Health Organization. Conclusions: It was possible to analyze the profile of compounded cardiovascular medicines prescribed in neonatology in Brazil. The results showed the need for the development of medications suitable for the neonatal population, and the standardization of operational procedures for preparing extemporaneous formulations in neonatology to increase drug safety.

Abstract The University Pharmacy Program (FU), from the Federal University of Rio de Janeiro (UFRJ), was created based on the need to offer a curricular internship to students of the Undergraduate Course at the Faculty of Pharmacy. Currently, it is responsible for the care of about 200 patients/day, offering vacancies for curricular internships for students in the Pharmacy course, it has become a reference in the manipulation of many drugs neglected by the pharmaceutical industry and provides access to medicines for low-income users playing an important social function. Research is one of the pillars of FU-UFRJ and several master and doctoral students use the FU research laboratory in the development of dissertations and theses. As of 2002, the Pharmaceutical Care extension projects started to guarantee a rational and safe pharmacotherapy for the medicine users. From its beginning in 1982 until the current quarantine due to the COVID-19 pandemic, FU-UFRJ has been adapting to the new reality and continued to provide patient care services, maintaining its teaching, research, and extension activities. The FU plays a relevant social role in guaranteeing the low-income population access to special and neglected medicines, and to pharmaceutical and education services in health promotion.

Abstract Hydrogels are used for wound treatment, as they may contain one or more active components and protect the wound bed. Papain is one of the active substances that have been used with this purpose, alongside urea. In this paper, carboxypolymethylene hydrogels containing papain (2% and 10% concentrations) and urea (5% concentration) were produced. Physical-chemical stability was performed at 0, 7, 15 and 30 days at 2-8ºC, 25ºC and 40ºC, as well as the rheological aspects and proteolytic activity of papain by gel electrophoresis. Clinical efficacy of the formulations in patients with lower limb ulcers was also evaluated in a prospective, single-center, randomized, double-blind and comparative clinical trial. The results showed 7-day stability for the formulations under 25ºC, in addition to approximately 100% and 15% of protein activity for 10% and 2% papain hydrogel, respectively. The rheological profile was non-Newtonian for the 10% papain hydrogel tested. There were no significant differences regarding the mean time for healing of the lesions, although 10% papain presented a better approach to be used in all types of tissue present in the wound bed.

Abstract The objective of this paper was to develop and evaluate two semi-solid pharmaceutical forms containing 0.1% tacrolimus: cream (CRT01) and gel (GLT01). For the evaluation of physicochemical stability, at times 0, 30, 60 and 90 days, at 23°C and at 40°C, High Performance Liquid Chromatography coupled with a Diode Array Detector (HPLC-DAD) was employed. This method was developed and validated for tacrolimus quantification. The occlusivity test and skin permeation assay were also performed, using an animal model (Wistar rats), and the CRT01 and GLT01 were compared to the 0.1% tacrolimus ointment (PFU01) obtained from the University Pharmacy, Federal University of Rio de Janeiro, Brazil. CRT01 and GLT01 presented a homogeneous aspect and consistency adequate for topical products, along with sensory characteristics above PFU01. They also presented adequate physicochemical stability for 90 days and a lower occlusive effect than PFU01 (p<0.05). CRT01 showed greater affinity for the skin when compared to PFU01 and GLT01, with low systemic absorption. The CRT01 semi-solid formulation was considered the most adequate one to treat patients with atopic dermatitis or other dermatologic inflammatory diseases, promoting rational use of tacrolimus.

Abstract The incorporation of antioxidants into sunscreens may provide additional skin photoprotection against the harmful photobiological effects of ultraviolet radiation. The present study evaluated the applicability of a screening approach to the assessment of the antioxidant and photoprotective properties of vitamin C, vitamin E, and coenzyme Q10 and then determined the performance of the most effective antioxidant in a sunscreen formulation. Antioxidant activity was assessed by the 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay, 2,2`-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) assay, and oxygen radical absorbance capacity (ORAC) assay, and the photoprotective potential was investigated by the yeast photoprotection assay. The antioxidant with the best effect was incorporated into sunscreen formulations which were evaluated for 120 days regarding their in vitro photoprotective parameters. Vitamin C showed high antioxidant capacity as well as a photoprotective potential against simulated solar irradiation applied for times longer than 1 h. Although the Sun Protection Factor, UVA/UVB ratio and critical wavelength did not differed significantly (p<0.05) between the formulation blank and the formulations containing 0.5% or 1% vitamin C, formulations with vitamin C kept their photostability for 6 months. Consequently, the proposed screening approach seems to be promising for the development of an antisolar photostable formulation containing vitamin C as an antioxidant.

This work deals with development and evaluation of MFQ protective formulation, which contains two organic filters, namely: octyl-p-methoxycinnamate (OMC) and benzophenone-3 (BP-3); a photostabilizing agent called ethylhexylmethoxycrylene (EHMCR) and keratin particles. The MFQ formulation was evaluated in order to measure its pH, spin-spin lattice relaxation time (T2H), occlusivity factor, formulation efficacy, photostability and skin permeation, as well as keratin particle properties. Keratin particle size increased when incorporated to formulation, however, it did not affect pH. The MFQ formulation was found to be photostable and photoprotective, as evidenced by sunlight photostability test, sun protection factor (SPF), UVA/UVB ratio and critical wavelength. Interaction between keratin particles and active substances (OMC, BP-3 and EHMCR) was evidenced by T2H measurements. Evidences suggest that keratin reduces the permeation of both UV filters employed along this study, therefore, it can be stated that keratin has a promising potential for use in sunscreen formulations.

Poly (ε-caprolactone) (PCL) based hybrids containing different amounts of modified (Aerosil® R972) and unmodified (Aerosil® A200) silica oxide were prepared employing the solution method, using chloroform. The relationships of the amount of nanofillers, organic coating, molecular structure and intermolecular interaction of the hybrid materials were investigated mainly using low-field nuclear magnetic resonance (NMR). The NMR analyses involved the hydrogen spin-lattice relaxation time (T1H) and hydrogen spin-lattice relaxation time in the rotating frame (T1ρH). The spin-lattice relaxation time measurements revealed that the PCL/silica oxide hybrids were heterogeneous, meaning their components were well dispersed. X-ray diffraction (XRD), differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) were also employed. The DSC data showed that all the materials had lower crystallization temperature (Tc) and melting temperature (Tm), so the crystallinity degree of the PCL decreased in the hybrids. The TGA analysis demonstrated that the addition of modified and unmodified silica oxide does not cause considerable changes to PCL's thermal stability, since no significant variations in the maximum temperature (Tmax) were observed in relation to the neat polymer.
