Is your pet experiencing minor aches or pain? It could be the result of a simple condition like arthritis or something more severe. If your pet has an inflammatory condition, or develops a form of cancer, then piroxicam may be prescribed by your veterinarian.
Piroxicam is a nonsteroidal anti-inflammatory and anti-tumor medication used to treat certain types of cancers such as colon, bladder, and prostate cancer as well as oral squamous cell carcinoma in dogs and cats. It is used to treat pain and help ease symptoms of arthritis such as swelling, stiffness, and joint pain. It can also be used to reduce the dosage needed of Methotrexate, a drug used for treating certain types of lymphoma.
Piroxicam can be taken with opioid analgesics to help your pet feel less drowsy while they are undergoing cancer treatments.
Piroxicam antitumor benefits work by acting on the immune system. Its antiangiogenic effect helps block nutrients and oxygen from tumors, not allowing them to grow. It can reduce the COx-2 enzyme which is responsible for causing swelling and inflammation and therefore is used to treat different types of tumors and pain.
It is well-absorbed into the body and should be given with food to decrease the likelihood of a stomach ulcer. Help your pet live a longer and better quality of life with Piroxicam. All our medications are made in our state-of-the-art pharmacy lab in Arizona, USA.
