Gastroretentive microballoons of olmesartan medoxomil: formulation and

Summary: Imagine a medicine that acts like a tiny life raft in your stomach. Olmesartan is a blood pressure medication that usually doesn't dissolve well, meaning your body only uses about 30% of what you swallow. To fix this, scientists created "microballoons"—tiny, hollow spheres filled with the drug. Because they are hollow, they float in the stomach for over 12 hours instead of sinking and passing through too quickly. This allows the medicine to be released slowly and absorbed better, making the treatment much more effective.
