Phenylpropanolamine is a substance used to treat urinary incontinence in dogs. It is particularly effective in strengthening the urethral sphincter and improving urinary tract function.

Essential insights

• Alpha-adrenergic stimulation: Phenylpropanolamine acts as a sympathomimetic agent, stimulating alpha-adrenergic receptors in the smooth muscle of the urethra. This increases sphincter tone and reduces urine leakage.
• Increased urethral pressure: Its direct effect on the urinary tract is to enhance urethral pressure, preventing involuntary urine flow.
• Minimal systemic effects: Phenylpropanolamine has minimal impact on other body systems, making it suitable for long-term use under veterinary supervision.
