Cardene, also known by its generic name nicardipine, is a calcium channel blocker used to treat high blood pressure. When administered in a plastic container, it is often found diluted in 4% dextrose solution.
Why is Cardene mixed with 4% Dextrose?
Mixing Cardene with 4% dextrose serves to dilute the medication to a safe and effective concentration for intravenous administration. Dextrose solutions are commonly used as carriers for intravenous drugs because they are isotonic or nearly isotonic with blood, helping to prevent adverse reactions at the injection site.
What are the indications for Cardene?
Cardene is indicated for the long-term management of chronic stable angina and for the treatment of hypertension [1]. It works by relaxing the blood vessels, which reduces the workload on the heart and lowers blood pressure [2].
How is Cardene administered intravenously?
When administered intravenously, Cardene is typically diluted in a compatible solution like 4% dextrose and infused over a period of time. The specific concentration and infusion rate depend on the patient's condition and response to treatment.
What are the potential risks associated with Cardene infusion?
Potential risks associated with intravenous Cardene include hypotension (low blood pressure), dizziness, headache, and local injection site reactions such as phlebitis [1]. Close monitoring of blood pressure and heart rate is essential during infusion.
What is the mechanism of action for Nicardipine?
Nicardipine is a dihydropyridine calcium channel blocker. It inhibits the influx of extracellular calcium ions across the membranes of myocardial cells and vascular smooth muscle cells, leading to vasodilation and a decrease in myocardial contractility [2].
