INTRAVESICAL
SUPPRESSION
LIPOSOMAL
TACROLIMUS
CYCLOPHOSPHAMIDE INDUCED OVERACTIVE BLADDER

Hypothesis / aims of study
Potent immunosuppressive effect of FK506 (tacrolimus) has encouraged its topical application for achieving local anti-
inflammatory effect. However, its poor aqueous solubility presents challenges in formulating safe, biocompatible instillations for
bladder. The present study investigated the feasibility of tacrolimus delivery using liposomes for intravesical
immunosuppression.
Study design, materials and methods
Adult female Sprague-Dawley rats( 52) divided into 4 experimental groups were injected with CYP (200 mg/kg, ip) except for
sham (saline injection, ip). Other three groups received either saline (1 cc, retained for 1 hr), liposome (LP- 1 cc) or liposomal
encapsulated tacrolimus (LFK- 0.2mg tacrolimus/1 ml LP) by intravesical route. Baseline cystometrogram was performed in all
the experimental groups except in sham on day 1 before any treatment and on day 3 prior to bladder harvest for histological
staining (N=24). In addition, 4-hr baseline urine on day 1 and day 3 was also collected from all experimental groups for urine
PGE2 assay and bladder harvested for PGE2 and IL2 assay on day 3 (N=28).


Results
CYP induced bladder inflammation was associated with increased EP4 staining, and bladder overactivity (intercontraction
interval 61.0% decrease). In addition, bladder PGE2 and IL2 level were both elevated 3.5 fold and urine PGE2 was increased
by 13.8 fold. Rats pretreated with LFK demonstrated suppression of CYP induced inflammatory reaction as revealed by
reduced EP4 staining, bladder overactivity and normalized IL 2 and PGE2 levels in tissue and urine. Intravesical LPs
pretreatment had no effects on uninjured rat bladder and did not suppress CYP effects.

Interpretation of results
LFK significantly inhibited CYP induced inflammation through the modulation of IL2, PGE2, and EP4 function. These findings
support investigation of local LFK for refractory overactive bladder.
Concluding message
This is the first report of intravesical immunesuppression in bladder by delivery of tacrolimus using liposomes.
