Maximum Dose of Norvasc (Amlodipine)
Introduction to Norvasc (Amlodipine)
Norvasc, also known by its generic name amlodipine, is a calcium channel blocker commonly prescribed for the treatment of hypertension and angina. It works by relaxing blood vessels, which allows blood to flow more easily, thereby lowering blood pressure and reducing the heart's workload.
Recommended Dosage and Administration
The typical starting dose of Norvasc for adults is 5 mg once daily. Depending on the patient's response and the severity of the condition, the dose can be increased. The maximum recommended dose of Norvasc is 10 mg per day .
Clinical Studies and Efficacy
Several clinical studies have evaluated the efficacy and safety of Norvasc at various dosages. In a study involving patients with chronic renal insufficiency and hypertension, Norvasc was administered at doses of 5 mg and titrated up to 10 mg daily. The study concluded that Norvasc effectively reduced both systolic and diastolic blood pressure without significant adverse effects.
Another study compared the effects of original and generic amlodipine in patients with arterial hypertension and obesity. Both forms of the drug were administered starting at 5 mg and increased to 10 mg if the target blood pressure was not achieved. The results showed significant reductions in blood pressure with both forms, confirming the efficacy of the 10 mg dose.
Safety and Side Effects
Norvasc has been evaluated for safety in over 11,000 patients in clinical trials. The drug is generally well-tolerated, with most adverse reactions being mild to moderate. Common side effects include headache, edema, dizziness, and palpitations. These side effects tend to be dose-related, with higher incidences observed at the 10 mg dose.
Special Considerations
While Norvasc is effective at doses up to 10 mg, caution is advised in certain populations. For instance, patients with severe hepatic impairment should be closely monitored due to the drug's extensive metabolism in the liver. Additionally, Norvasc should be used with caution in patients with severe aortic stenosis and those with congestive heart failure.
Conclusion
The maximum recommended dose of Norvasc is 10 mg per day. Clinical studies have demonstrated its efficacy and safety at this dosage for the treatment of hypertension and angina. However, as with any medication, it is essential to consider individual patient factors and potential side effects when determining the appropriate dose. Always consult a healthcare provider for personalized medical advice.
