This is a combination product containing 2 medications: methocarbamol and ibuprofen. It is used to relieve pain associated with muscle spasm such as strains and sprains, back pain, and tense neck muscles. Methocarbamol belongs to a class of medications called muscle relaxants and they reduce muscle spasms. Ibuprofen belongs to a class of medications called nonsteroidal anti-inflammatory drugs (NSAIDs) that reduce pain and inflammation.
The torr (symbol: Torr) is a non-SI unit of pressure with the ratio of 760 to 1 standard atmosphere, chosen to be roughly equal to the fluid pressure exerted by a millimeter of mercury, i.e., a pressure of 1 Torr is approximately equal to one millimeter of mercury.
A pressure that causes the Hg column to rise 1 millimeter is called a torr (you may still see the term 1 mm Hg used; this has been replaced by the torr). 1 atm = 760 torr = 14.7 psi. Bar (bar) The bar is nearly identical to the atmosphere unit. One bar = 750.062 torr = 0.9869 atm = 100,000 Pa. Millibar (mb or mbar) There are 1,000 millibar in one bar. This unit is used by meteorologists who find it easier to refer to atmospheric pressures without using decimals. One millibar = 0.001 bar = 0.750 torr = 100 Pa. Pascal (Pa)
