Tailoring or modulation of drug release from delivery systems comprises a major area of research in pharmaceutical field where the primary objective is to either sustain drug release or to design orodispersible tablets. This objective can be successfully achieved by use of a class of natural excipients - gums and mucilages. These polysaccharidic plant-derived biopolymers because of their unique swellability in aqueous medium can exert a retardant effect on drug release or can act as superdisintegrant, depending on the concentration used in the formulation. Mechanism of drug release from...

The duration of diabetes, and fasting blood sugar values were significantly higher in patients with diabetes with severe CAN. Prolongation of QTC interval correlates well with degree of cardiac autonomic neuropathy in diabetics. QTC prolongation may be considered as pointer towards diabetic cardiac autonomic neuropathy in the busy outpatient setting where it is not possible to perform the conventional battery of tests. Recognition of QTC prolongation may help identify diabetics with a high risk of sudden cardiac death. Trying to manage diabetes is hard because if you don't, there are...
