What effect does low blood pressure have on the absorption of medication?

Low blood pressure can significantly impact the absorption of medication in the body. When blood pressure is low, there may be decreased perfusion to various organs and tissues, including the gastrointestinal tract where many medications are absorbed. This reduced blood flow can lead to a slower absorption of the medication into the bloodstream.

As a result, the time it takes for the medication to reach therapeutic levels in the body can be prolonged, leading to a slower onset of action. In contrast, higher blood pressure typically enhances perfusion, facilitating quicker absorption. Therefore, when blood pressure is low, the effects of the medication may be delayed as it takes longer for the active ingredients to be absorbed and distributed throughout the body.
