Hi Rhonda. Enbrel is a class of biological medication (https://rheumatoidarthritis.net/treatment/biologics-treatment-options-for-ra/) called a TNF inhibitor. It is designed to block a chemical in your body called TNF that contributes to the inflammatory processes involved in RA. If TNF can be blocked, then the joint pain, swelling, and damage may be reduced. Enbrel is a particular type of anti-TNF drug really in a class by itself (it has a particular molecular structure different than the others). There are other TNF blocker drugs in a slightly different class which include Humira and Remicade...both of which are popular and have been around for many years. I suspect your doctor will go with one of those. Humira is self-injected usually every two weeks and Remicade requires administration at an infusion clinic. Because of ease of use, most go for the Humira. They both are similar in their effectiveness and side effect profile.
It's not really a matter of stronger drugs but different. For those who don't respond to anti-TNF drugs, there are other biological medicines to try. Everyone is different and responds differently to different drugs. In addition, sometimes people build up anti-bodies against the biological drugs over time and they stop working.
I hope that you find the right combination to get your RA under control.
