Question

A biphasic drug effect occurs when a drug effect first goes in one direction as drug dose increases, but the effect changes direction as drug dose continues to increase.

A. True
B. False

Answer 1

A biphasic drug effect occurs when a drug effect first goes in one direction as drug dose increases, but the effect changes direction as drug dose continues to increase.

Step-by-step explanation:

A biphasic drug effect occurs when a drug effect first goes in one direction as drug dose increases, but the effect changes direction as drug dose continues to increase. It can be thought of as a U-shaped response curve where the effect initially increases with dose, reaches a maximum, and then decreases with further dose increases.

For example, consider a painkiller medication. At low doses, the painkiller may provide relief and decrease pain. However, at higher doses, it may start causing adverse effects or even increase the sensation of pain.

This phenomenon is observed in certain drugs and can be influenced by various factors such as drug metabolism, receptor kinetics, and the body's response to the drug.
