Eye Drops Get a Smart Upgrade for Glaucoma Treatment

Glaucoma is a tricky eye condition. It needs constant care. But what if eye drops could work better and last longer? Researchers have found a way to make this happen. They created tiny bubbles called liposomes. These bubbles carry the medicine dorzolamide hydrochloride. This medicine helps treat glaucoma. The liposomes make the medicine stay in the eye longer. They also help the medicine work better. The team used special methods to make these liposomes. They tested different mixes to find the best one. The winning mix had 200 mg of phosphatidylcholine and 40 mg of cholesterol. This mix made the best liposomes. These liposomes are tiny. They are about 98. 22 nm in size. They also have a negative charge. This helps them stay in the eye longer. The best part? They can hold a lot of medicine. Almost 97. 5% of the medicine stays inside the liposomes.The team tested these liposomes in the lab. They found that the medicine releases slowly. It lasts for 8 hours. This is much longer than normal eye drops. The medicine also moves better through the eye. It works 1. 8 times better than regular eye drops. Safety is important. The team tested the liposomes on eggs and rabbits. They found that the liposomes are safe. They don't irritate the eyes. They are also the right strength. This means they won't hurt the eyes. This new way of delivering medicine could change glaucoma treatment. It could make life easier for people with glaucoma. They won't need to use eye drops as often. The medicine will work better and last longer.
