Diabetes is a chronic disease that occurs either when the pancreas does not produce enough insulin or when the insulin it produces cannot be effectively used.
Insulin is a hormone that regulates blood glucose levels. When this regulation fails, it leads to hyperglycaemia (raised blood sugar)—a hallmark of uncontrolled diabetes.
Over time, persistently high blood sugar can result in serious complications, including heart disease, stroke, kidney damage, nerve injury, and vision loss.
New treatment protocol:-
- A groundbreaking study introduces a non-invasive transdermal insulin delivery system using a pH-responsive polyzwitterion polymer called OP (poly[2-(N-oxide-N,N-dimethylamino)ethyl methacrylate]).
- This innovation aims to overcome one of the biggest challenges in drug delivery—the skin’s barrier to large molecules like insulin.
Working Principle:-
- The polymer temporarily loosens tightly packed skin lipids, allowing insulin to pass through it.
- It binds and protects insulin, enabling a stable transport.
- Enables insulin absorption without injections
Clinical Promise:-
- Non-invasive and painless
- Avoids complications of invasive methods (e.g., microneedles, ultrasound)
- Reduces risk of drug degradation and first-pass metabolism
This study suggests a future where insulin could be delivered through the skin using smart polymers, making diabetes care more comfortable and accessible. However, it remains an emerging technology and is not yet ready for clinical practice.
