Budipine is an antiparkinson agent.

Its mechanism of action is not well characterized.[2] It is believed to be an NMDA receptor antagonist,[3] however, promoting the synthesis of dopamine.[4]

Because it provides additional benefits relative to existing treatments, it probably does not precisely mimic the mechanism of an existing known treatment.[5]
