If there's any hope at all for him, the Excede should do the trick. I wouldn't be adding more drugs to the mix without the blessing of the vet. Many of the drugs are antagonistic to each other, and will negate any benefits to each other.
Hopefully, his lungs haven't been permanently damaged beyond repair. Sometimes these "lungers" will seem to recover quite well, but as they grow bigger, their lung capacity isn't able to develop normally, and they eventually get big enough that their lungs can't provide enough Oxygen to support their larger bodies. They are also not able to expel the carbon dioxide that their bodies produce, so they eventually die. Hope this doesn't happen to yours.
