The antipsychotic medications (Thorazine, Compazine, Mellaril, Stelazine, Haldol, etc.) work exactly in the reverse way as L-DOPA (they block and/or deplete Dopamine), and some patients on these drugs develop abnormal movements of the face (lip-smacking, etc.) after being on these drugs for a time. The syndrome is usually reversible with discontinuation of the drugs; but, after a while, it can become irreversible. Hope this helps.
