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.
The mercury barometer is the standard instrument for atmospheric pressure measurement in weather reporting. The decrease in atmospheric pressure with height can be predicted from the barometric formula. The unit mmHg is often called torr, particularly in vacuum applications: 760 mmHg = 760 torr. For weather applications, the standard atmospheric pressure is often called 1 bar or 1000 millibars.
