Actually no guys, sorry...

I am not a pharmacist either but I am a physiotherapist and I work in a large Melbourne public hospital.

Drugs that are inhalable (i.e. ventolin) are inhalable for a reason and usually because you get a better dose effect or you want them to work specifically on the lungs. Sometimes inhalable drugs have other effects (i.e. ventolin) on the body.

If you administer drugs intravenously, you can get a stronger effect (or more dangerous effect) or alternatively no effect at all.

If you mix a drug with any other substance you cannot guarantee that you will:
a) maintain the efficacy of the drug (so it may be useless)
b) not cause any harmful interactions

As I said, I am not a pharmacist, but I would caution very strongly against administering any drug not as per medical instructions - it is not that simple.
