If m is const, then only const methods can be called on it. Maybe you can change your method to

const char* Medicine::getName() const;

and use it like this:

const char* n=m.getName();

Although you might consider using an std::string data member instead of an array of char.

Please note that if the member variable is const, only const member function can access this. Same for static, i.e if the member variable is static only a static member can access that.
