What is nisoldipine, and how does it work (mechanism of action)?
Nisoldipine is an oral calcium channel blocker (CCB) of the dihydropyridine (DHP) class that is used to treat high blood pressure. Other calcium channel blockers in the DHP class include nifedipine (Procardia, Adalat), amlodipine (Norvasc), felodipine (Plendil), nicardipine (Cardene), and isradipine (Dynacirc). Calcium channel blockers prevent calcium from entering certain types of muscle cells. Since the muscle cells need calcium to contract, CCBs prevent the cells from contracting, that is, they cause the muscle cells to relax. Nisoldipine selectively relaxes the muscles of small arteries causing the arteries to dilate but has little or no effect on muscles of veins or the heart. Dilation of arteries reduces blood pressure. Nisoldipine was approved by the FDA in February of 1995.
What are the side effects of nisoldipine?

What is the dosage for nisoldipine?
The recommended dose is 17 to 34 mg or 20 to 40 mg daily depending on the formulation that is used. Doses may be increased at one week intervals. Tablets should be swallowed whole and taken on an empty stomach. Individuals with poor liver function require lower doses of nisoldipine.
Which drugs or supplements interact with nisoldipine?
Cimetidine (Tagamet) or any drug that reduces the activity of liver enzymes that break down nisoldipine can increase blood levels of nisoldipine, possibly causing more side effects. Examples of drugs that may reduce break down of nisoldipine include ketoconazole, itraconazole (Sporanox), and erythromycin.
Is nisoldipine safe to take if I'm pregnant or breastfeeding?
The effects of nisoldipine in pregnancy are unknown.
It is unknown if nisoldipine appears in breast milk.
What else should I know about nisoldipine?
What preparations of nisoldipine are available?
Tablets (Extended Release): 8.5, 17, 20, 25.5, 30, 34, and 40 mg.
How should I keep nisoldipine stored?
Tablets should be stored below 30 C (86 F) and should be protected from light and moisture.

Amlodipine besylate (Norvasc) is a drug that belongs to the drug class of calcium channel blockers (CCBs), and is prescribed for the treatment and prevention of angina (heart or chest pain) that results from coronary spasm and from exertion. Norvasc also is prescribed for the treatment of high blood pressure. Side effects include:
Drug interactions, dosing, and pregnancy and breastfeeding safety information should be reviewed prior to taking any medication.
Angina SymptomsAngina is chest pain due to inadequate blood supply to the heart. Angina symptoms may include chest tightness, burning, squeezing, and aching. Coronary artery disease is the main cause of angina but there are other causes. Angina is diagnosed by taking the patient's medical history and performing tests such as an electrocardiogram (EKG), blood test, stress test, echocardiogram, cardiac CT scan, and heart catheterization. Treatment of angina usually includes lifestyle modification, medication, and sometimes, surgery. The risk of angina can be reduced by following a heart healthy lifestyle.
Bepridil (Vascor, Bepadin) is a drug prescribed for the treatment of angina pectoris due to coronary artery disease. Bepridil is no longer available in the US. Side effects, drug interactions, dosage, and pregnancy and breastfeeding safety should be reviewed prior to taking this medication.
Calcium Channel Blockers
Calcium channel blockers (CCBs) are a class of drugs that dilate the arteries, and are used for treating:
- High blood pressure
- Abnormally rapid heart rhythms
- Pulmonary hypertension
- Raynaud's syndrome
- Subarachnoid hemorrhage
Calcium channel blockers also are prescribed for the prevention of migraine headaches and angina.
CCBs may also be prescribed after a heart attack.
Examples of calcium channel blockers (CCBs) approved in the U. S. include:
- nisoldipine (Sular)
- nifedipine (Adalat, Procardia)
- nicardipine (Cardene)
- isradipine (Dynacirc)
- nimodipine (Nimotop)
- felodipine (Plendil)
- amlodipine (Norvasc)
- diltiazem (Cardizem)
- verapamil (Calan, Isoptin)
Drug InteractionsDrug interactions occur frequently. Get facts about the types of drug interactions, what substances or other things that may interact with drugs such as OTC drug and prescription drugs, vitamins, food(s) (grapefruit), and laboratory tests. Find out how to protect yourself from potential drug interactions.
Drugs: What You Should Know About Your DrugsImportant information about your drugs should be reviewed prior to taking any prescription drug. Side effects, drug interactions, warnings and precauctions, dosage, what the drug is used for, what to do if you miss a dose, how the drug is to be stored, and generic vs. brand names.
Febrile SeizuresFebrile seizures, or convulsions caused by fever, can be frightening in small children or infants. However, in general, febrile seizures are harmless. Febrile seizure is not epilepsy. It is estimated that one in every 25 children will have at least one febrile seizure. It is important to know what to do to help your child if he/she has a febrile seizure. Some of the features of a febrile seizure include:
- losing consciousness,
- moving limbs on both sides of the body,
- lasts 1-2 minutes.
Felodipine (Plendil) is a drug prescribed for the treatment of high blood pressure to prevent heart attack and stroke. Doctors also prescribe it to treat patients for angina, however, it is not an FDA approved drug for this condition.
Common side effects include:
- Increased heart rate
- Low blood pressure
Drug interactions, dosing, warnings, and pregnancy and breastfeeding safety information should be reviewed prior to taking this medication.
High Blood Pressure HypertensionHigh blood pressure is defined as a pressure of 140/90 mmHg or higher in the arteries. Genetic factors, high salt intake, and increased arterial stiffness cause high blood pressure. Dizziness, headache, nausea, and shortness of breath are just a few symptoms of high blood pressure. Untreated high blood pressure increases the risk of heart disease, kidney disease, atherosclerosis, eye damage, stroke, and increased risk of aneurysms. High blood pressure can be managed with weight loss, lifestyle changes, and medication.
High Blood Pressure Medication
High blood pressure (hypertension) medications include drugs from a variety of different drug classes and types.
- ACE inhibitors
- ARB (angiotensin receptor blockers)
- Beta blockers
- Calcium channel blockers (CCBs)
- Alpha-beta blockers
Clonidine (Catapres) and minoxidil also are drugs prescribed for the treatment of high blood pressure. Side effects, warnings and precautions, safety information, and pregnancy and breastfeeding safety information should be reviewed prior to taking any medication.
High Blood Pressure TreatmentHigh blood pressure (hypertension) means high pressure (tension) in the arteries. Treatment for high blood pressure include lifestyle modifications (alcohol, smoking, coffee, salt, diet, exercise), drugs and medications such as ACE inhibitors, angiotensin receptor blockers, beta blockers, diuretics, calcium channel blockers (CCBs), alpha blockers, clonidine, minoxidil, and Exforge.
