Understanding Drug Release Data through Thermodynamic Analysis
(Mdpi Ag, 2017-06-01)
Understanding the factors that can modify the drug release profile of a drug from a Drug-Delivery-System (DDS) is a mandatory step to determine the effectiveness of new therapies. The aim of this study was to assess the ...
Release Kinetic in Yogurt from Gallic Acid Microparticles with Chemically Modified Inulin
(Institute of Food Technologists, 2015)
Gallic acid (GA) was encapsulated with native (NIn), cross-linked (CIn) and acetylated (AIn) inulin by spray-drying. Inulin microparticles were characterized by encapsulation efficiency (EE) and their release profile in ...
Release and permeation profiles of spray-dried chitosan microparticles containing caffeic acid
(2018-03-01)
Caffeic acid (CA), a phenolic compound found in plants with antioxidant and antimicrobial activity, induces collagen production and prevents premature aging of the skin. The objective of this study was to develop two types ...
Acetylated starch and inulin as encapsulating agents of gallic acid and their release behaviour in a hydrophilic system
(2012)
Gallic acid (GA) was encapsulated with native starch (NS), native inulin (NIn), acetylated starch (AS) or acetylated inulin (AIn) (two substitution degrees each) by spray-drying, and a 2 2 statistical factorial design was ...
Release kinetics of flavonoids in methyl linoleate from microparticles designed with inulin and channelizing agent
(Elsevier Ltd, 2014)
Quercetin (Q), naringenin (N) and epicatechin (E) were encapsulated with inulin (In) as encapsulating agent and Capsul (C) as channelizing agent by spray drying and applying a Box-Behnken design. Q-In, N-In, E-In, Q-In-C, ...
Caffeine Encapsulated in Small Unilamellar Liposomes: Characerization and In Vitro Release Profile
(Taylor & Francis Inc, 2013-10-03)
Liposomes containing hydrogenated soy phosphatidylcholine (PCH), with or without cholesterol (CHOL) and caffeine (CAF), were prepared by sonication and characterized for encapsulation efficiency and mean diameter. Dynamic ...
Electrochemical Behavior of Verapamil at Graphite-Polyurethane Composite Electrodes: Determination of Release Profiles in Pharmaceutical Samples
(TAYLOR & FRANCIS INC, 2009)
A solid graphite-polyurethane composite electrode has been used to determine release profiles of verapamil, a calcium-channel blocker. The electro-oxidation process was characterized by cyclic voltammetry and electrochemical ...
Dual Release Model to Evaluate Dissolution Profiles from Swellable Drug Polyelectrolyte Matrices
(Bentham Science Publishers, 2020-05-11)
Background: Mathematical modeling in modified drug release is an important tool that allows predicting the release rate of drugs in their surrounding environment and elucidates the transport mechanisms involved in the ...
