Alternatives to 177Lu-DOTATE include yttrium-90 DOTATATE or DOTATOC. The longer range of the beta particles emitted by 90Y, which deliver the therapeutic effect, may make it more suitable for large tumors with 177Lu reserved for smaller volumes

The U.S. Food and Drug Administration (FDA) considers 177Lu dotatate to be a first-in-class medication.
