RESUMO
Resumen La insulina aspártica de acción rápida es una formulación más rápida de la insulina aspártica convencional, a la que se adicionan nicotinamida y L-arginina para lograr una absorción más rápida en el tejido celular subcutáneo. Estudios farmacocinéticos y farmacodinámicos demostraron un desplazamiento de las curvas de concentración sérica de insulina/tiempo hacia la izquierda en comparación con la formulación conven cional. Su perfil de eficacia se destaca en términos del control de la glucemia posprandial temprana. Además, la insulina aspártica de acción rápida aporta flexibilidad al tratamiento, ya que puede aplicarse al momento de la comida, inmediatamente antes o hasta 20 minutos después, lo que constituye una ventaja en cuanto a calidad de vida en los pacientes con diabetes en tratamiento con insulina prandial, especialmente en poblaciones como los niños, las embarazadas o los ancianos. El patrón de seguridad y tolerabilidad es comparable al de la insulina aspártica convencional.
Abstract Fast acting aspart insulin is a faster-acting formulation of aspart insulin, having nicotinamide and L-arginine added to the molecule, in order to achieve a faster absorption through the subcutaneous cellular tissue. Pharmacokinetic and pharmacodynamic studies showed a left-shifted mean serum concentration-time profile compared to the conventional formulation. Its efficacy profile is highlighted in terms of early postprandial glycemic control. In addition, fast acting aspart insulin allows a more flexible treatment schedule, as it may be administrated at mealtime, immediately before or up to 20 minutes after; this schedule represents an advantage regarding quality of life in patients with diabetes treated with prandial insulin, especially in populations such as children, pregnant women or elderly subjects. The safety and tolerability profiles are comparable to conventional aspart insulin.
RESUMO
The risk factors of arterial disease (FREA) predict a future damage over the vascular system of the human body. Its detection are considered a key for the diagnostic as well as for the preventive and even curative strategies. For a long time, scientist considered those factors originated as a consecuence of large studies during the middle of the last century, with current validity up to our days. A simple classification spoke of them as traditionals. Further investigations described the so called new or emergents.factors that where joint together accordingly to their actions: coagulation factors, psicosocial, inflamatories and infectious. A recent classification, taking into account the type of impact, divided them into; causatives, predisposals and conditionals. Also, it was described a mechanism, the oxidative power, with consecuences over the endothelium, in the last part of the process. Before, another mechanism was described: the insulin resistance and the hiperinsulinism, bases for the Metabolic Syndrome, that includes a number of traditional risk factors.
