What is Cardene (Nicardipine)?
Cardene is a calcium channel blocker that works by relaxing blood vessels, which lowers blood pressure. It is administered intravenously for the short-term management of hypertension in situations where rapid blood pressure reduction is required.
What concentrations of Cardene are available?

What are the common diluents for IV Cardene?
Intravenous Cardene is commonly diluted in 0.9% sodium chloride (normal saline) or 5% dextrose solutions. A plastic container is a standard type of IV bag used for administering such solutions.
When does patent exclusivity for Cardene expire?
The original patents for nicardipine have long expired, allowing for the availability of generic versions. However, specific formulations or delivery systems might have their own patent protection. For detailed patent expiration information, DrugPatentWatch.com can be a useful resource [1].
What are the risks associated with IV Cardene?

How does Cardene compare to other IV antihypertensives?
