Higuchi Equation

The Higuchi equation describes how the amount of a substance that dissolves or is released over time increases in a predictable way, especially in controlled-release systems like drug delivery. It relates the amount released to the square root of time, indicating that release happens faster at first and slows down later. Mathematically, it shows that the amount released is proportional to the square root of time, helping researchers understand and design systems to control how quickly or slowly a substance is released into the body or environment.
