Levodopa is one of the effective drugs in the treatment of palsy tremor. It is one of the precursors for the synthesis of norepinephrine and dopamine in the body and belongs to catecholamine. Levodopa can enter the brain through the blood-brain barrier, and is converted into dopamine by dopamine decarboxylase. However, the obvious effect is slow, and the side effects are larger (refer to the relevant literature)
