Orphenadrine belongs to the group of medications called skeletal muscle relaxants. It is used to treat acute muscle spasms.
Muscle tightening or spasms result largely from signals in the nervous system telling the muscles to tighten or contract. Orphenadrine helps to relieve muscle tightening and stiffness by reducing the strength of those signals in the nervous system.
Muscle relaxants such as orphenadrine are used to help relieve the stiffness, pain, and discomfort caused by sprains and strains of the muscles in the neck, back, or other areas of the body. Your doctor may prescribe additional treatments such as appropriate rest, exercise, or physical therapy to help your stiff muscles.
