Characterization of Liquid Dosage Forms of Atenolol and Enalapril Maleate for O...
Mota, Sandra; Torres, Ana; Quintas, Clara; Peres, António M.; Ferreiro, Nuno Manuel; Cruz, Rebeca; Ferreira, Helena; Almeida, Isabel F.; Casal, SusanaThe limited availability of pharmaceutical formulations tailored for cardiovascular diseases in both pediatric and geriatric populations generates the need for compounded dosage forms to guarantee precise dosing and medication adherence. This study aimed to analyze the physicochemical properties and stability of formulations of atenolol and enalapril maleate prepared with a proprietary oral vehicle, SuspendIt®....
Comparative Studies on the Photoreactivity, Efficacy, and Safety of Depigmentin...
Mota, Sandra; Rosa, Gonçalo P.; Barreto, Maria Carmo; Garrido, Jorge; Sousa, Emília; Cruz, Maria T.; Almeida, Isabel F.; Quintas, Clara; Garrido, JorgeDepigmenting products are increasingly used to counteract skin hyperpigmentation and related psychosocial issues. This study aimed to compare different depigmenting agents—4-butylresorcinol; bakuchiol; tranexamic acid; ascorbyl glucoside; α-arbutin; and ascorbic acid—for photoreactivity; tyrosinase inhibition; and safety. Photoreactivity was assessed using the Reactive Oxygen Species assay. In vitro tyrosinase ...

A Hydrophilic Sulfated Resveratrol Derivative for Topical Application: Sensitiz...
Jesus, Ana; Sebastião, Ana I.; Brites, Gonçalo; Correia-da-Silva, Marta; Cidade, Honorina; Cruz, Maria T.; Sousa, Emília; Almeida, Isabel F.Resveratrol (RSV), a naturally occurring metabolite, is widely used in skincare products, but its hydrophobicity impairs its own incorporation into cosmetic formulations. RSV-GS is a synthetic hydrophilic sulfated glycosylated derivative inspired by marine natural products that present a lower cytotoxicity than RSV while exhibiting similar levels of bioactivity. Herein, we predict the skin sensitization potenti...
How to Promote Skin Repair? In-Depth Look at Pharmaceutical and Cosmetic Strate...
Torres, Ana; Rego, Liliana; Martins, Márcia S.; Ferreira, Marta S.; Cruz, Maria T.; Sousa, Emília; Almeida, Isabel F.Skin repair encompasses epidermal barrier repair and wound healing which involves multiple cellular and molecular stages. Therefore, many skin repair strategies have been proposed. In order to characterize the usage frequency of skin repair ingredients in cosmetics, medicines, and medical devices, commercialized in Portuguese pharmacies and parapharmacies, a comprehensive analysis of the products' composition w...
Antioxidants in Sunscreens: Which and What For?
Jesus, Ana; Mota, Sandra; Torres, Ana; Cruz, Maria T.; Sousa, Emília; Almeida, Isabel F.; Cidade, HonorinaUltraviolet (UV) radiation promotes the generation of reactive oxygen species (ROS) and nitrogen species (RNS), resulting in skin damage. Cosmetic industries have adopted a strategy to incorporate antioxidants in sunscreen formulations to prevent or minimize UV-induced oxidative damage, boost photoprotection effectiveness, and mitigate skin photoaging. Many antioxidants are naturally derived, mainly from terres...

Pinto, Susana; Gomes, Joana; Ogbonna, John Dike N.; Cunha, Edite; Attama, Anthony A.; Ofokansi, Kenneth C.; Ferreira, Helena; Marx, ÍtalaO sabor amargo de fármacos constitui uma barreira à adesão terapêutica em pediatria. Existem disponíveis várias estratégias para mascarar o amargor, mas a maioria é de difícil implementação na Farmácia Hospitalar (FH). Desenvolvimento de um veículo para administração oral para uso pediátrico, de composição simples e de fácil preparação, com o objetivo de mascarar o sabor amargo de um fármaco modelo com elevado ...
