Define Potency

Potency is a measurement used to define the effectiveness of a drug or medication. It is calculated based on the desired result and a patient's physical characteristics.

Significance

• Potency is used to aid pharmacists in determining the correct dosage for a patient. This measurement is important, because it ensures that patients will not overdose.

Function

• Potency is primarily useful in determining the effectiveness of a drug. The higher the potency of a drug, the more effects will be seen from its use. It also helps to determine how a person may be harmed by a drug's use.

Considerations

• High potency drugs tend to be dangerous and require professional consultation before use. If a drug is known to have a high potency rating, it is important to consult a doctor before use.

Theories/Speculation

• It is considered that over time, a drug can lose its potency. This is dependent on the drug, how it is made and the original potency. While some drugs may naturally lose their effectiveness, some may retain their full potency.

Expert Insight

• Dr. Walt Stoll remarks that the potency of a drug does not necessarily make it better than any other drug. If a drug A is 100 times more potent than drug B, it means nothing in regard to quality.
