    (Incdtp-Icpi, 2018) Draghici, Roxana-Denisa; Marin, Maria Minodora; Ghica, Mihaela Violeta; Kaya, Madalina Georgiana Albu; Anuta, Valentina; Dinu-Pirvu, Cristina; Kaya, Durmus Alpaslan
    The sport injuries become more and more frequent so there is a need to discover new solutions for increasing the quality of life for people affected by such wounds. The aim of this study was to obtain a novel NSAID drug delivery system, topical diclofenac spongious matrices based on collagen and alginate for the treatment of injuries and relieving of pain. The samples were analyzed by flow analysis and after their freeze-drying were analyzed by FT-IR and in vitro release of sodium diclofenac.The results obtained from analyses confirmed that diclofenac spongious matrices based on collagen and alginate exhibit proper characteristics for the treatment of injuries and relieving of pain.

    The aim of this paper is to design and characterize some drug delivery systems (DDS) based on collagen hydrolysates (H), niflumic acid as a non-steroidal anti-inflammatory model drug and two essential oils of Lavandula officinalis L. (LO) and Lavandula stoechas L. subsp. Stoechas (LS), for use in healing cutaneous wounds with post-lesion inflammatory response. The essential oils are characterized by GC-MS. The wettability capacity of collagen hydrolysate powders was assessed by contact angle measurement. Niflumic acid release was investigated using a modified Franz diffusion cell, and the diffusion coefficient, time-lag and drug flux were determined. The kinetic parameters were found to be influenced by different concentrations and types of essential oils. These therapeutical products, based on collagen hydrolysates and synergistic drug associations, could have potential biomedical application in wound healing treatment.
