Okay, it's made by Mylan
Pharmaceuticals Inc. and according to this it is made up of
MS CONTIN tablets are for oral use and contain morphine
sulfate, an agonist at the mu-opioid
Each tablet contains the following inactive ingredients common to all strengths: cetostearyl alcohol
, hydroxyethyl cellulose, hypromellose, magnesium stearate, polyethylene glycol, talc and titanium dioxide.
The tablet strengths describe the amount of morphine per tablet as the pentahydrated sulfate salt (morphine sulfate).
The 15 mg tablets also contain: FD&C Blue No. 2, lactose, polysorbate 80
The 30 mg tablets also contain: D&C Red No. 7, FD&C Blue No. 1, lactose, polysorbate 80

Morphine sulfate is an odorless, white, crystalline powder with a bitter taste. It has a solubility of 1 in 21 parts of water and 1 in 1000 parts of alcohol, but is practically insoluble in chloroform
or ether. The octanol: water partition coefficient of morphine is 1.42 at physiologic
pH and the pKb is 7.9 for the tertiary nitrogen
(mostly ionized at pH 7.4).
I can put up the structural picture if you want, but if this is good enough
