Besides the heroin ... cops found a laundry list of prescription meds in Philip Seymour Hoffman's apartment ... including pills to treat addiction, ADHD, and anxiety.
According to law enforcement sources ... investigators found methocarbamol (muscle relaxer), hydroxyzine (anti-anxiety), Vyvanse (ADHD), and buprenorphine to treat addiction ... and clonidine hydrochloride (blood pressure).
It's unclear at this point if Hoffman had prescriptions for any of the drugs.
Of course the pills were just a small part of the stash cops found. As we've reported ... there were 50 bags of heroin as well as used and unused hypodermic needles.
