What is the difference between modafinil and armodafinil?

Modafinil and armodafinil are both used to help people who have trouble staying awake during the day. While they are similar, they are not exactly the same.

1. Chemical Structure: Modafinil is a mixture of two molecules, while armodafinil contains only one of these molecules. This means armodafinil might work differently in the body.

2. Effectiveness and Duration: According to the studies, armodafinil may last longer in the body compared to modafinil. This can be helpful for people who need to stay awake for longer periods.

3. Plasma Concentrations: The studies also show that the levels of these medicines in the blood can be different. Armodafinil tends to reach a higher level in the blood than modafinil.
