Commonly known as Vicodin ES. The pill is a combination of 7.5mg Hydrocodone (a semi-synthetic narcotic pain reliever) and 750mg of APAP (Tylenol). It is manufactured by Mallinckrodt pharmaceuticals who also produces the common Hydrocodone/APAP combination pills M357. M353 etc.
I enjoy music more with a few M360's.
