What is Cardene in 0.86% Sodium Chloride?
Cardene is a brand name for nicardipine hydrochloride, a calcium channel blocker used to treat high blood pressure. When administered in a 0.86% sodium chloride solution and contained in a plastic bag, it is typically presented as an intravenous (IV) infusion [1]. This formulation is used in hospital settings for rapid control of blood pressure, particularly in situations like hypertensive emergencies [2].
Why is it in 0.86% Sodium Chloride?
The 0.86% sodium chloride solution, often referred to as normal saline, serves as the diluent for intravenous medications like nicardipine hydrochloride [3]. This concentration of sodium chloride is isotonic, meaning it has a similar salt concentration to blood plasma, making it suitable for IV administration without causing significant shifts in fluid balance within the body's cells [4]. This ensures the drug is delivered effectively and safely into the bloodstream.
How is Cardene Administered Intravenously?
Cardene for IV use is typically administered as a continuous infusion using an infusion pump [2]. The rate of infusion is carefully controlled by healthcare professionals to achieve and maintain the target blood pressure. Dosage and administration parameters are adjusted based on the patient's response, clinical condition, and other medications they may be receiving [5].
When Does Nicardipine Patent Protection Expire?
The patent for the original nicardipine formulation has long expired, allowing for the availability of generic versions. However, specific formulations or delivery systems might have separate patent protections. DrugPatentWatch.com tracks patent expirations for various drugs and their formulations, providing detailed information on when market exclusivity ends for specific products [6].
Are There Other Brands of Nicardipine IV?
While Cardene is a prominent brand, nicardipine hydrochloride is also available under other brand names and as a generic medication for intravenous use. The choice of brand may depend on hospital formularies and availability [7].
What Are the Risks of Using Cardene IV?
Like all medications, Cardene IV can have side effects. Common side effects include headache, nausea, vomiting, dizziness, and flushing [8]. More serious adverse effects, though less common, can include significant drops in blood pressure, irregular heart rhythms, and liver problems [9]. Patients receiving Cardene IV are closely monitored for these potential risks.
How Does Cardene IV Compare to Oral Nicardipine?
Cardene administered intravenously provides a rapid and predictable onset of action, making it suitable for acute situations where immediate blood pressure control is necessary [2]. Oral nicardipine, while effective for chronic hypertension management, has a slower absorption and onset of action and is not typically used for emergency blood pressure reduction [10].
