What is Ozobax used for?
Ozobax is a prescription medicine that is used to treat spasms in patients with MS (multiple sclerosis) or spinal cord disease. Ozobax may be given to you for other reasons.

Molecular formula is C1OH12CINO2.
Molecular Weight is 213.66.
Baclofen USP is a white to off-white, odorless or practically odorless crystalline powder. It is slightly soluble in water, very slightly soluble in methanol, and insoluble in chloroform.
The OZOBAX (baclofen) oral solution inactive ingredients are: citric acid anhydrous, glycerin, natural grape flavor, methylparaben, propylparaben, purified water, sodium citrate dihydrate, and sucralose. May also contain sodium hydroxide or hydrochloric acid for pH adjustment.
Mechanism of Action
The precise mechanism of action of baclofen is not fully understood. Baclofen inhibits both monosynaptic and polysynaptic reflexes at the spinal level, possibly by decreasing excitatory neurotransmitter release from afferent terminals, although actions at supraspinal sites may also occur and contribute to its clinical effect. Baclofen is a structural analog of the inhibitory neurotransmitter gamma- aminobutyric acid (GABA), and may exert its effects by stimulation of the GABAB receptor subtype.
