Intraperitoneal injection

Intraperitoneal injection
Other namesIP injection
ICD-9-CM54.96-54.97

Intraperitoneal injection or IP injection is the injection of a substance into the peritoneum (body cavity). It is more often applied to non-human animals than to humans. In general, it is preferred when large amounts of blood replacement fluids are needed or when low blood pressure or other problems prevent the use of a suitable blood vessel for intravenous injection.[citation needed]

In humans, the method is widely used to administer chemotherapy drugs to treat some cancers, particularly ovarian cancer. Although controversial, intraperitoneal use in ovarian cancer has been recommended as a standard of care.[1] Fluids are injected intraperitoneally in infants, also used for peritoneal dialysis.[citation needed]

Intraperitoneal injections are a way to administer therapeutics and drugs through a peritoneal route (body cavity). They are one of the few ways drugs can be administered through injection, and have uses in research involving animals, drug administration to treat ovarian cancers, and much more. Understanding when intraperitoneal injections can be utilized and in what applications is beneficial to advance current drug delivery methods and provide avenues for further research. The benefit of administering drugs intraperitoneally is the ability for the peritoneal cavity to absorb large amounts of a drug quickly. A disadvantage of using intraperitoneal injections is that they can have a large variability in effectiveness and misinjection.[2] Intraperitoneal injections can be similar to oral administration in that hepatic metabolism could occur in both.
