Absorption Intra-arterial administration of cisplatin results in increased tumor exposure to the drug compared with intravenous administration ( As previously mentioned, intraperitoneal administration of cisplatin results in reduced systemic absorption compared with intravenous administration (Kireeva et al., 2020)
