A well-studied treatment with a long window of action
Cialis is the brand name for tadalafil, a PDE5 inhibitor first approved by the FDA in 2003. It is used to treat erectile dysfunction (ED) and the urinary symptoms of benign prostatic hyperplasia (BPH). One of its distinctive features is its duration of action — effects can last up to 36 hours — which is why it is sometimes called the “weekend pill.” Like all prescription medicines, it must be used under medical supervision and is not suitable for everyone.
