Long-Lasting Drugs  Long-Lasting Drugs  Long-Lasting Drugs

Here is a video showing an experiment to understand the mechanism of drugs. Let's write a report on the expected results of the experiment and what you learned from watching the video.

 What is the reason for the different colors of the grains?
What is the reason for the different colors of the grains?

Some long-acting medicines are capsules containing different colored granules.
The different-colored granules take different amounts of time to start working, and are designed to keep working for a longer period of time.

Drugs are used to cure diseases and injuries. If not used correctly, they can be harmful to the body, so don't imitate the experiments.

Results of the experiment!

The white grains dissolve quickly, while the orange grains do not dissolve as quickly.

White granules dissolve and are absorbed quickly in order to make the medicine work faster. On the other hand, orange-colored capsules are designed to dissolve slowly in order to make the drug work for a longer period of time. The capsules contain grains that dissolve in different ways, making them not only work quickly, but also stay effective for a longer period of time.
If the capsules are taken separately, the desired effect will not be obtained. Do not open the capsule and take the capsule as it is.

For the purpose of the experiment, we opened the capsule and removed the capsules. When taking capsules, be sure to take them as they are.
