Is fasting required for intravenous administration of streptozotocin? Any answer appreciated.

Is fasting required for intravenous administration of streptozotocin? Any answer appreciated.

No, because it's IV: If a medication is IV, generally you do not have to fast — since 'absorption' from the stomach is completely bypassed. Definitely though Streptozotocin or streptozocin can give you nausea, so I would recommend to take your anti nausea medications BEFORE you take the infusion. Hopefully you can get through this treatment OK. Definitely talk to your doctor though if you have questions. Hang in there ...Read more

Why is dobutamine given intravenously?

Why is dobutamine given intravenously?

No other form: Presently, there is no other form of Dobutamine on the market. Generally, when Dobutamine is used, one is seeking immediate action of the drug, if the drug was administered through just about any other route, it would take longer to act and the delay in action is not desirable.
