I had the pleasure of watching "Professor Popper's Problems" on the Disney channel in 1989. (They put the extra "s" at the end of the title.) It involves a professor at a British school who has developed a shrinking pill. He and a couple of his boy students test the pill, and sure enough, they shrink to a few inches in height. But growing back to normal is a little more complicated, and making things more complicated still are rivals who want to kidnap the shrunken professor and get the formula from him.
This movie was never a shoo-in for the Academy Awards and it isn't exactly a classic, but it is reasonably pleasant (especially for the kids) and is entertaining.
