Phenoxybenzamine is a smooth muscle relaxer used in pets reduce bladder problems. It is often used in dogs or cats that had a recent urinary blockage. It may also be used to treat other disorders such as high blood pressure.
How It Works
Alpha adrenoreceptors are located in the blood vessel walls, and the blockage of them leads to the opening of the vessels, lowering blood pressure. Phenoxybenzamine also relaxes the urethral sphincter muscles, which can relax the urethra, allowing urine to pass.
