Yes, other things like muscle relaxers, alcohol, anti-depresents, etc. can have pain relief properties for some people in some circumstances. However, these other things aren't primarily analgesics.
There are three non-narcotic analgesic categories. I'm not sure if my link organizes it that way, but that's the standard system. The fourth category of analgesics, opiates, is usually broken down by strength into sub-categories. Inside the categories there tends to be a variety of options. Drug companies are constantly iterating on the classes.
My hypothesis is that the profit motive to keep selling opioids to adicts and future adicts outweighs the profit motive for a new drug that could be used for pain but wouldn't have the additional pecuniary benefit of creating a market for addicts and future addicts.
My argument is that opiates are an easy category of chemicals to develop for purposes of pain management because they work directly on the endogenous system that controls pain. The variety of opiate-based pain management for serious pain is a consequence of human biology. I also think that there is intense demand for a non habit forming alternative that is just as effective that would make a ton of money if it could be developed, but developing it isn't simply a matter of want-to. The demand side favors non-addictive substances.
