Capsule drugs float in water because their density is less than that of water. If your neck is upturned, swallow the water first, and then swallow the capsule. Because there is no water in the mouth at this time, the capsule will stick to the mouth and is not easy to swallow. If you lower your head, the capsule floats near your throat. When you start swallowing, you will swallow the capsule for the first time, and then you will follow up with a lot of water, saying that the capsule will directly rush into your stomach. So it will be easy to eat.

Because the density of tablets is higher than that of water, they are in a sinking state in water, so at this time, it is necessary to tilt the neck and let the tablets close to the throat, so that the tablets can be swallowed directly at the first time, and a large amount of water will be sent down.
