I'm really worried about my dad. He's had a stroke and a bypass in the past, and his heart rate usually hangs around 55 to 60. I've heard about Chymoral AP and Myoril for his lower back pain, but I'm concerned if it's safe for him to take because of his heart condition. Could you please guide me on this?

Chymoral AP and Myoril can be risky for your father due to his history of stroke and bypass surgery, as well as his low heart rate. Chymoral AP contains Trypsin, Chymotrypsin, and Paracetamol which can increase the risk of bleeding, especially in patients with a history of stroke. Myoril contains Thiocolchicoside which can cause muscle weakness and dizziness, potentially increasing the risk of falls in someone with a history of stroke. Given his low heart rate, both medications can further lower the heart rate and blood pressure, leading to complications. It is important to consult with his healthcare provider to find a safer alternative for his lower back pain.
