Hello and welcome to the forum. Thanks for your question. It's a good one. There actually are other medications to benefit cholesterol. Here is some information for you: https://www.heart.org/en/health-topics/cholesterol/prevention-and-treatment-of-high-cholesterol-hyperlipidemia/cholesterol-medications.
Statins have really become the gold standard of therapy for lowering cholesterol as they are generally well tolerated and work well but not everyone can take them or have different lipid needs addressed. I would say Resins is a rising class of medication for these and are under brand names like Questran.
Do you have high cholesterol? Don't forget too that lifestyle changes can impact your numbers for a lot of people. https://www.nhlbi.nih.gov/files/docs/public/heart/chol_tlc.pdf
