What signifies a drug’s strength?

The strength of a drug is defined by the dosage form or concentration specified in the prescription. This includes details such as the amount of active ingredient present in a defined volume or mass of the drug. For example, a prescription may specify a certain concentration of a liquid medication (e.g., 5 mg/mL) or a specific dosage form like a tablet containing a certain amount of the active substance. This information is crucial in ensuring that the patient receives the right amount of medication for their condition.

Other factors, such as the color of the tablet, may provide information about the specific formulation or manufacturer, but they do not convey the drug's strength. Similarly, packaging might indicate the brand or product but does not determine the concentration of active ingredients. The expiry date is important for safety and efficacy but does not relate to the strength of the drug itself. Thus, understanding the dosage form and concentration is key to recognizing a drug's strength.
