been getting 54-543 tablets oxy 5-325 not as fast acting and long lasting as the mallenkrodt 512 tabs...5-325...is there a difference?
There can be differences in medications made by different manufacturers. Generic drugs can vary from the brand name original by plus or minus 20%. So if you're comparing two generics, conceivably one could 20% more effective and the other 20% less effective, which would mean that there could actually be a 40% difference between the two generics.

Brand Name vs. Generic Drugs: Are They Really the Same?
yeah the 512's seem a little bit more stronger. the 54-543 tablets dont have the APAP in them which makes them a little bit easier on your liver. Different people get different effects from pills. Personally I like the 512 version better also.
