Delivery of Naturally Occurring Hormone (Insulin) Via Insulin Pens and Pumps - A Way Forward for Diabetes Treatment

Diabetes treatment is associated with different costs depending upon the type of curative approach used. Most of the time, insulin is administered by two main techniques: cartridges and vials. Insulin pens have emerged as alternative devices for insulin administration. In 2009, the consumption of insulin through insulin pens/cartridges in high-income countries is about 90% while in low-income countries is around 10%. Insulin pens are the main insulin delivery devices utilized approximately 75% and 67% in Japan and Europe, respectively. Better patient comfort and most advantageous glycemic control have lead to the extensive use of insulin pens. Preparation of insulin dose is the major limitation associated with insulin injection using vial and syringe delivery. Additionally, there may be chances that incorrect dose can be administered by mistake. This makes the discovery of insulin pens to overcome such problems. Administration of insulin is mainly carried out by numerous means. Various literatures presented for verification that supports the use of insulin pens over traditional insulin vials because of to lower overall costs. This article highlights the benefits and advancements of insulin delivery devices in controlling and treatment of diabetes.
