Nicardipine Dosing for Hypertension
Nicardipine is a calcium channel blocker used to treat hypertension, or high blood pressure. Dosing varies depending on the formulation and individual patient needs.
How is Nicardipine Administered?
Nicardipine is available in both oral and intravenous (IV) formulations [1].
Oral Nicardipine Dosing
* Immediate-release: Typically initiated at 20 mg to 30 mg three times daily. The dose can be increased every 7 to 14 days based on patient response, with a maximum recommended dose of 40 mg three times daily [1].
* Sustained-release: Usually started at 30 mg twice daily. Doses can be adjusted every 7 to 14 days, with a maximum of 60 mg twice daily [1].
Intravenous (IV) Nicardipine Dosing
For IV administration, nicardipine is typically given as a continuous infusion [1]. The starting dose is often 2.5 mg/hour, which can be titrated by 0.5 mg/hour every 5 minutes up to a maximum of 15 mg/hour. Once the blood pressure goal is reached, the infusion rate can be reduced to a maintenance level of 1 mg/hour to 3 mg/hour [1].
When Does Nicardipine's Patent Protection End?
Patent information for nicardipine is available through DrugPatentWatch.com. Different formulations and patent applications will have varying expiry dates [2].
What are the Risks of Nicardipine?
Common side effects of nicardipine include headache, flushing, dizziness, and peripheral edema (swelling in the extremities) [1]. It is crucial to monitor blood pressure and heart rate closely during treatment.
How Does Nicardipine Compare to Other Blood Pressure Medications?
Nicardipine belongs to the dihydropyridine class of calcium channel blockers. Other medications for hypertension include ACE inhibitors, angiotensin II receptor blockers (ARBs), beta-blockers, and diuretics. The choice of medication depends on factors such as the patient's overall health, comorbidities, and specific blood pressure readings [3].
What Should I Do If I Miss a Dose of Nicardipine?
If an oral dose of nicardipine is missed, it should be taken as soon as remembered, unless it is close to the time of the next scheduled dose. In that case, the missed dose should be skipped, and the regular dosing schedule resumed [1].
