In which administration technique is chemotherapy delivered directly into the bladder?

The administration technique in which chemotherapy is delivered directly into the bladder is known as intravesicular. This method allows for localized treatment, specifically targeting bladder tumors or conditions. The chemotherapy agent is instilled directly into the bladder through a catheter, which can lead to higher concentrations of the drug at the site of the tumor while minimizing systemic exposure and potential side effects. Intravesicular therapy is commonly used for superficial bladder cancer and can be a crucial component of treatment protocols in managing this disease.

In contrast, intraperitoneal administration involves delivering chemotherapy directly into the peritoneal cavity, primarily used for certain types of abdominal cancers. Intradermal administration refers to delivering medication into the dermis layer of the skin, often utilized for vaccinations or allergy tests. Intramuscular administration involves injecting the chemotherapy into muscle tissue, which is less specific than intravesicular delivery and is typically used for broader systemic treatment rather than localized therapy.
