Current methods available to administer insulin include various invasive parenteral techniques like the subcutaneous, intramuscular, and intravenous routes. The subcutaneous route is used more often and includes rapid, short, long, and intermediate-acting insulin. However, currently used techniques have numerous disadvantages. Insulin when administered as an injectable is invasive, reduces patient compliance and is hence not preferred. Insulin delivery through the parenteral route calls for multiple daily injections, which may inconvenience many patients since they are often accompanied by lipodystrophy, severe pain, damage to tissues, and allergic or hypersensitivity reactions at the site of injection. Moreover, the manner in which it is administered itself makes it tedious to perform at public places. Novel Drug Delivery Systems have become trendy as they provide tangible advantages like decreased dosage and enhanced bioavailability, and aid in preventing degradation from the harsh gastric environment. The search for a safe and precise delivery system for insulin that gives a controlled and sustained release remains under research.
Yes their is need of innovation in drug delivery system for insulin. As per moder Era their are many development in medicine. As we know it is very pain full process to inject parenteral doses and requires proper doses to injection to it’s appropriate area. As their are transdermal patches which transfer specific doses and its time interval.
