Estriol is an estrogen hormone. It differs from DES or other estrogens because it is naturally occurring and occupies the receptor for a shorter duration compared to synthetic compounds. When used to treat urinary incontinence, its effects are believed to be caused by increasing sensitivity of alpha-adrenergic receptors in urinary smooth muscle.
Estriol is an estrogen replacement. In small animals, it has most often been used to treat urinary incontinence that is associated with estrogen deficiency. Success rate may be limited. Estriol has increased sphincter tone in urethra of female dogs but has limited efficacy when used in clinical treatment.
