Development of Novel Intravesical Formulation for Bladder Retention Targeting Bladder Disorders

Numerous bladder-related diseases, including urinary blockages, interstitial cystitis, overactive bladder syndrome, cancer, and infections of the urinary tract, can affect bladder function. The human urinary bladder's distinct anatomy successfully prevents any hazardous material from entering circulation. The pathogenesis was assessed according to the extent of invasion in the bladder wall tissue obtained through Transurethral Resection of Bladder Tumor (TURBT) and classified as Muscle-Invasive and Non-Muscle Invasive Bladder Cancer (MBIC and NMIBC). Intravesical Drug Delivery (IDD) has recently gained attention for treating bladder disorders. IDD refers to the insertion of a drug directly into the bladder using a catheter. Intravesical administration of immunotherapy or chemotherapy has been demonstrated to reduce recurrence rates and inhibit disease progression. In addition, several other systems, including recombinant BCG, gene therapy, vectors, and Antibody-Drug Conjugates (ADCs), are now used. Moreover, the novel intravesical formulations of distinct chemotherapeutic agents, including gemcitabine, Doxorubicin (DOX), and Mitomycin C (MMC), are used in bladder-related problems. Novel intravesical drugs, polymeric hydrogels, dendrimers, hydrogels, mucoadhesives, nanocarriers, and intravesical devices have been discussed. Aside from chemotherapy and immunotherapy, devices such as GemRIS, device-assisted hyperthermic intravesical chemotherapy, and photodynamic therapy are utilized.
