RESUMEN
BACKGROUND: Since the introduction of the first reusable insulin pen, the advancement in the design of these pens is still ongoing to develop a safe, more efficacious, less painful, and easy to use insulin pen device. MAIN BODY: Possible errors in insulin delivery can occur at any stage of insulin delivery such as during the prescription stage, dispensing stage, or at administration stage. Mismatch of the insulin pen and cartridge is not uncommon and is a potential risk for individuals with diabetes due to serious consequences associated with incorrect insulin usage. The similarities in insulin cartridges of different manufacturers with regard to color and product names could lead to mix-up of insulin pens and cartridges. These unmet needs have led to the ongoing search for developing insulin pens that can address these errors and provide more efficacious and safer choices for patients with diabetes. CONCLUSION: This review provides an overview of currently available reusable pens in the market and highlights the features of TouStar®, a new reusable pen with a dedicated cartridge intended to mitigate the risk of mismatch of the cartridge.
RESUMEN
A series of 7-substituted-3-cyclobutylamino-4H-1,2,4-benzothiadiazine-1,1-dioxide derivatives has been synthesized and evaluated as K(ATP) channel agonists using the inside-out excised patch clamp technique. The most active compounds were approximately 20-fold more potent than diazoxide in opening K(ATP) channels. A linear relationship exists between the potency of the compound and the sigma value of the 7-substituent with electron-withdrawing groups exhibiting higher activity. These compounds may be useful in modulating insulin release from pancreatic beta-cells and in diseases associated with hyperinsulinemia.
