Are there extrapyramidal symptoms occur with thorazine, haldol, (haloperidol) mellaril, or cardiazem?

Some: Yes for the first 3 which are 1st generation antipsychotic meds. I've not heard of it or suspect for cardiazem (diltiazem) which is a heart med. Extrapyramidal sx (eps) include: tremors, stiffness, restlessness. They can be managed by dosage reduction, change in med or by giving meds that counter such as cogentin, propranolol, amantadine and sometime ativan.

EPS: Discuss with your prescribing doctor. Depending on the type of EPS, there are many medications to manage them.

Extrapyramidal side: effects may be treated with medications like pramipexol, benztropine (Cogentin), diphenhydramine (Benadryl), or trihexyphenidyl (Artane).
