Unlike cyclobenzaprine (the active ingredient in Flexeril), Norflex does not primarily act on serotonin receptors; instead, it blocks acetylcholine at muscarinic acetylcholine receptors.

Muscle relaxants are also used to treat skeletal muscle spasms (tension, cramping, or involuntary contractions). For example, they are used to treat muscle spasms caused by conditions such as acute low back pain, tension headaches, and fibromyalgia. Some of the muscle relaxants used to reduce muscle spasms include cyclobenzaprine, methocarbamol, carisoprodol, metaxalone, chlorzoxazone, and orphenadrine.

The serotonin-norepinephrine reuptake inhibitors (SNRIs) are a newer group of antidepressants, which, like the TCAs, act by inhibiting serotonin and norepinephrine reuptake. Venlafaxine and duloxetine are the most familiar drugs in this category; they have less alpha-1, cholinergic, or histamine inhibition than the TCAs. This results in fewer side effects than the TCAs, with equivalent antidepressant and potentially equal analgesic benefits. Placebo-controlled studies have demonstrated efficacy in neuropathic pain for both venlafaxine and duloxetine. Orphenadrine use with propoxyphene (removed from the U.S. market in 2011) may cause confusion, anxiety, and tremors, perhaps because of additive effects.
