Contact the schools. Likely, one would have to apply as a college graduate looking for a spot as a first year medical school student. Contact the medical schools directly to see what the requirements are, and to see if one's college courses are acceptable. To see what is in the mcat (medical college admission test), one can buy one of the study guides. Additional requirements may be required from foreign students.
