Question: 1 / 400

What effect do direct-acting skeletal muscle relaxants have on muscle contractions?

Increase muscle stiffness

Decrease the force of reflex muscle contractions

Direct-acting skeletal muscle relaxants primarily work by acting on the muscle fibers themselves, rather than on the central nervous system. These medications reduce the amount of calcium available for muscle contraction, which leads to a decrease in the force of reflex muscle contractions. This reduction in force allows for improved muscle relaxation and alleviation of conditions that involve muscle stiffness or spasms.

The focus of these medications is on decreasing excessive or involuntary muscle activity, which is particularly useful in managing conditions such as muscle spasticity or tension. By decreasing the force of muscle contractions, these relaxants help prevent the excessive tightening and involuntary movements associated with muscle spasms, providing relief for patients who experience these uncomfortable symptoms.
