MIT researchers successfully develop a capsule that can deliver insulin orally, offering hope for a more convenient and painless management of the disease
Insulin in a pill: new research answers a question that has puzzled diabetes researchers for 100 years.
For nearly a century, scientists have been searching for a way to deliver insulin in pill form. Insulin is a hormone that regulates blood sugar levels and is essential for people with diabetes. However, the current method of delivery, through injections or pumps, can be painful and inconvenient.
Recently, researchers at the Massachusetts Institute of Technology (MIT) have made a breakthrough in the development of an insulin pill. The team, led by Dr. Robert Langer, has created a capsule that can protect insulin from being broken down in the stomach and deliver it to the small intestine, where it can be absorbed into the bloodstream.
The capsule, which is about the size of a blueberry, is made of a special material that can withstand the acidic environment of the stomach. Inside the capsule is a small needle made of compressed insulin, which is released when the capsule reaches the small intestine. The needle dissolves in the intestine, releasing the insulin into the bloodstream.
The team has tested the capsule in pigs and found that it was able to deliver insulin at the same rate as injections. They are now planning to test the capsule in humans. The development of an insulin pill could have a significant impact on the lives of people with diabetes. It would provide a more convenient and painless way to manage the disease, and could also make it easier for people to adhere to their treatment regimen.
This new research is a promising step towards the development of an insulin pill, and it offers hope to the millions of people living with diabetes. However, more research is needed before the capsule can be made available to the public.
Why is there no insulin pill?
There is currently no insulin pill available on the market because insulin is a large protein molecule that is broken down by enzymes in the stomach before it can be absorbed into the bloodstream. This makes it difficult to deliver insulin orally in pill form. Additionally, insulin is sensitive to changes in pH and temperature, which can affect its effectiveness.
Scientists have been researching ways to overcome these challenges for decades. One approach is to use a special coating or capsule that can protect the insulin from the stomach's acid and deliver it to the small intestine, where it can be absorbed. Another approach is to use nanoparticles or microneedles that can deliver insulin through the skin.

The team, led by Dr. Robert Langer, has created a capsule that can protect insulin from being broken down in the stomach and deliver it to the small intestine, where it can be absorbed into the bloodstream. However, this is still in the early stages of research and more testing is needed before it can be made available to the public.
In short, the development of an insulin pill is a complex and ongoing process that requires finding ways to protect insulin from being broken down in the stomach and deliver it to the small intestine, where it can be absorbed into the bloodstream.
Mimicking insulin with simple molecules
Mimicking insulin with simple molecules is an area of research that aims to develop compounds that can mimic the effects of insulin in the body without using the actual hormone. This approach is based on the idea that small molecules can bind to the same receptors in the body that insulin binds to, and thus produce similar effects on glucose metabolism and insulin sensitivity.
One example of a simple molecule that mimics insulin is metformin. Metformin is a drug that is commonly used to treat type 2 diabetes. It works by increasing insulin sensitivity in the liver and muscles, which helps to lower blood glucose levels. Metformin does not directly mimic insulin's effects on the body, but it does share some similar effects.
Another example is GLP-1 receptor agonists, a class of drugs that mimic the effects of the hormone GLP-1, which regulates insulin secretion and appetite. GLP-1 receptor agonists are used to treat type 2 diabetes by stimulating insulin secretion and slowing gastric emptying. Researchers are also looking at the potential use of compounds such as Incretin-based therapies, which mimic the action of incretin hormones that stimulate insulin secretion in response to meals. These drugs are also used to treat type 2 diabetes.
In conclusion, mimicking insulin with simple molecules is an active area of research in diabetes. Some compounds, such as metformin and GLP-1 receptor agonists, have already been developed and are used to treat diabetes. More research is needed to identify additional compounds that can mimic insulin's effects and potentially provide new treatment options for people with diabetes.
In conclusion, scientists at MIT have made a significan
t step towards the development of an insulin pill, which could have a huge impact on the lives of people with diabetes. The new capsule is able to protect insulin from being broken down in the stomach and deliver it to the small intestine, where it can be absorbed into the bloodstream. Further testing is needed before the capsule can be made available to the public.
