Mdr1, a plasma membrane protein, inside a living cell, able to pump out drug molecules.

This will encourage other researchers to develop web server for public use, which may lead to decrease the cost of discovering new drug molecules.

It is sometimes used as a carrier for drug molecules in pharmaceutical preparations.

The effect is often reached within 5 min for smaller drug molecules.

For example, in a higher dose, a specific drug molecule may also bind to other receptors than those said to be "selective".

Toxicological screening is important to ensure safety of the drug molecules.

If a drug molecule is too large, or dissolves in stomach acid, it must be given as a shot.

The Benzocyclobutene moiety has also appeared in a number of drug molecules.

They could hold small drug molecules transporting them to the desired location.

Triggered response is one way for drug molecules to be used more efficiently.
