What are the ratings of various Vicodins?

When I went to the dentist a year ago I was given 500mg/5mg tyleonl/hydrocodone tablets with the phrase ‘M357’ on them. My dad has gout and has M361 tablets that are 500mg/10mg. What other numbers are there on Vicodin tablets and what do they stand for? What are M360, M367, and the others? I have heard Vicodin varies from 500mg/5mg to 500mg/50mg.

At the bottom of this page is listed the US names and dosages of several different proportions of hydrocodone/APAP tablets, going under the trade names Vicodin, Lortab, Maxidin, and Norco.

This page does not have the markings. Perhaps someone with a PDR can help you.

They are (sorted by hydrocodone/APAP content):
2.5/500
5/325
5/500
7.5/325
7.5/500
7.5/650
7.5/750
10/325
10/500
10/650
10/750
