In-vitro and In-vivo Studies of the Diclofenac Sodium Controlled-release Matrix Tablets

Abstract: Controlled release matrix tablets for diclofenac sodium were developed in this study. Five matrix-tablet formulations were prepared by granulating two viscosity grades of HPMC (hydroxylpropylmethylcellulose) in varying ratios with water in the planetary mixer. The in-vitro dissolution tests indicate that all five matrix formulations prolong the release of diclofenac sodium. The main factors controlling drug release were the HPMC viscosity grade and the amount of HPMC used. The larger the amount of high viscosi… Show more

“…It is most often used to reduce pain, inflammation, and stiffness caused by many conditions, such as osteoarthritis or rheumatoid arthritis, as well as a pain killer in some types of cancer (Oberle et al 1984;Liu et al 1995). As a result of its short half-life, the daily dose of the drug for an adult with rheumatoid arthritis is 75-100 mg/24 hr.…”

“…Para maioria dos produtos, as conclusões de eficácia clínica e segurança são baseadas nos parâmetros farmacocinéticos, derivados da curva de concentração plasmática em função do tempo (BLUME; SCHUG, 1999;CHEN;LESKO;WILLIAMS, 2001). A bioequivalência de um medicamento assume que, entre o medicamento teste e referência, o mesmo efeito é produzido visto este ser em função da concentração com que a substância ativa atinge a circulação (KARALIS et al, 2008).…”

“…São observados alguns estudos que avaliam a performance in vivo de comprimidos de liberação controlada contendo DCL (LIU et al, 1995;VENI;JAYASAGAR, 2001;SU et al, 2003;GARBACZ et al, 2008). Esses e outros estudos de biodisponibilidade do DCL são realizados a partir da quantificação do fármaco no plasma por HPLC e detecção UV.…”
