Tyra is a brand name for tadalafil, which is a medication commonly used to treat erectile dysfunction (ED) and the symptoms of benign prostatic hyperplasia (BPH). It works by relaxing the muscles of the blood vessels, allowing increased blood flow to specific areas of the body, such as the penis, which helps achieve and maintain an erection when sexually aroused. The 5mg dosage is often used for daily use in the treatment of ED or BPH. When taken regularly, it can help improve erectile function on a continual basis, without the need to time doses around sexual activity.
