Nuevos copolimeros de injerto han sido introducidos como excipientes de potencial aplicación para sistemas matriciales de liberación controlada. Se trata de copolímeros resultantes del injerto de metacrilato de metilo sobre derivados de celulosa y almidón
Dual-nozzle fused deposition modeling (FDM) is a 3D printing technique that allows for the simultaneous printing of two polymeric filaments and the design of complex geometries. Hence, hybrid formulations and structurally different sections can be combined into the same dosage form to achieve customized drug release kinetics. The objective of...
Stimuli-responsive polymersomes have emerged as smart drug delivery systems for programmed release of highly cytotoxic anticancer agents such as doxorubicin hydrochloride (Dox·HCl). Recently, a biodegradable redox-responsive triblock copolymer (mPEG–PDH–mPEG) was synthesized with a central hydrophobic block containing disulfide linkages and two...
Ultrasound-assisted compression (USAC) is a technology combining a conventional compression process and US irradiation. These mechanical and thermal effects lead to heating, melting and sintering of materials. This article reviews the principles of ultrasound-assisted compression and its main applications in pharmaceutical technology. Physical...
Direct-compressed matrix tablets were obtained from a variety of potato starch-methyl methacrylate copolymers1 as sustained-release agents, using anhydrous theophylline as a model drug. The aim of this work was to investigate the influence of the copolymer type, the tablet crushing force and dissolution variables such as the pH of the...
Background Despite a wide range of medications being available for the prevention of cardiovascular events such as stroke, myocardial infarction and mortality in both a primary and secondary setting, patient adherence to complex therapy regimens involving different drug classes remains low worldwide. Combining antiplatelet, antihypertensive,...
The two main purposes of this work were: (i) to critically consider the use of thermodynamic parameters of activation for elucidating the drug release mechanism from hydroxypropyl methylcellulose (HPMC) matrices, and (ii) to examine the effect of neutral (pH 6) and acidic (pH 2) media on the release mechanism. For this, caffeine was chosen as...
Introduction: Venous thromboembolism is a major global health burden. Since the 1930s, prevention of stroke and pulmonary embolism in these patients has been achieved using conventional anticoagulants, such as heparin and warfarin. However, in recent years, four direct non-vitamin K antagonist oral anticoagulants (DOACs) have entered the market...
A previous paper [1] deals with the physicochemical and technological characterization of novel graft copolymers of ethyl methacrylate (EMA) on waxy maize starch (MS) and hydroxypropylstarch (MHS). The results obtained suggested the potential application of these copolymers as excipients for compressed non-disintegrating matrix tablets....
Pharmaceutical antagonism of the mineralocorticoid receptor (MR) can protect against organ damage caused by elevated aldosterone levels in patients experiencing heart failure (HF), chronic kidney disease (CKD), primary aldosteronism, and hypertension. While traditional steroid-based MR antagonists effectively reduce mortality rates and extend...
This study evaluates in vivo the drug absorption profiles from potato starch-methyl methacrylate matrices∗ using theophylline as a model drug. Healthy beagle dogs under fasting conditions were used for in vivo studies and plasma samples were analyzed by a fluorescence polarization immunoassay analysis (FPIA method). Non-compartmental and...
Aortic stenosis (AS) is a progressive and degenerative disease that necessitates valve replacement through either surgical aortic valve replacement (SAVR) or transcatheter aortic valve replacement (TAVR). Various studies have shown that, unlike for TAVR, SAVR is associated with an elevated risk for women as compared to men. The aim of this...
Valvular heart disease (VHD) is a chronic progressive condition with an increasing prevalence in the Western world due to aging populations. VHD is often diagnosed at a late stage when patients are symptomatic and the outcomes of therapy, including valve replacement, may be sub-optimal due the development of secondary complications, including...
