Is there a medicine with butalbital by itself or w/o tylenol? - fioricet butalbital

A friend Fioricet headache and contains sedatives "butalbital" in combination with paracetamol and caffeine. I want to avoid finding paracetamol and caffeine from their obvious negative effects and a way to take butalbital for yourself? I would like any information that could cause or butalbital. Thanks
