Tag: Systemic effect

The global transdermal skin patches market was valued at USD 7.82 billion in 2023 and is a key method for drug delivery [1.6.1]. The fundamental question for many is: **do transdermal medications have a systemic effect?** The answer is yes; they are specifically designed for this purpose [1.2.1, 1.2.5].

Studies have revealed that dextromethorphan, a common cough suppressant, can be detected in the bloodstream within hours of a single dose. This demonstrates that the answer to the question, how does cough syrup work if you swallow it, involves a systemic, full-body process rather than just a topical action on the throat.
