Criminal Court Process?

I have a friend that was taken to the Magistrate court. Without getting too much into detail, he was falsely accused of something. The person accusing him claimed that he damaged personal property. This portion of the case was dismissed completely with no consequence against my friend. However, the accuser has also stated that my friend made threats with a deadly weapon. I know my friend, and know that they would not do this. This portion of the case is now being carried forward, unfortunately. When I asked, the response I got was "big court." I am uming that this is the court of common pleas? I know that these are false accusations, and that the accuser is trying to make my friend's life a living hell. He will need to request off from work again for this, and its pretty embarring to go to your boss and tell this story. Is there any way for this case to get thrown out before it reaches trial? Is there anything my friend can do to prevent being brought into court again for something else the accuser decides to make up? Thank you in advance for your help!
