                   }//end function

This is because in a URL + means space.

You'll need to URL encode the data first before adding it to the query string.

You can use the encodeURIComponent() function to encode your value before adding it to the query string.

Once your PHP code picks it up you can then decode the value with the urldecode function

So your code should update to something like this:

url: 'modules/medicos/controller.php?fun=consul_item&nombre_item=consul_item'+
                                  '&nombre_item='+encodeURIComponent(nombreItem)+
                                 '&campo='+encodeURIComponent(campoItem)+
                                 '&comparador='+encodeURIComponent(comparativeItem)+
                                 '&tabla='+encodeURIComponent(tableItem),

Your code seems to be correct. You are passing those variables one by one (nombreItem, campoItem, comparativeItem and tableItem). So I don't really understand what you say is not working.

A suggestion to make passing data easier:

$.ajax({
      type: 'POST',
      async: false,
      url: 'modules/medicos/controller.php',
      data : ({ fun : consul_item,
                  nombre_item : nombreItem,
                  campo : campoItem,
                  comparador : comparativeItem,
                  tabla : tableItem }), 
      success: function(data) {
            result = data;
      },
      failure: function() {
            result = "";
      }
});

If you want to pass all your info as one textual string you should do:

...
data: ({ test : consul_item + '+' + nombreItem + '+' + campoItem + '+' + comparativeItem + '+' + tableItem }), 
...
