Small interfering RNA (siRNA) therapeutics have emerged as a trans formative class of drugs, offering targeted gene silencing capabilities that hold promise for treating various diseases. Since the landmark approval of the first siRNA drug Patisiran in 2018, the therapeutic siRNA landscape has expanded significantly, with multiple drugs, including Givosiran, Lumasiran, Inclisiran, and Vutrisiran, now approved in both the US and EU markets. Understanding these drugs’ absorption, distribution, metabolism, and excretion (ADME) characteristics is critical for optimizing their development and clinical application of siRNA therapeutics.
