How does it work? Adalat capsules contain the active ingredient nifedipine, which is a type of medicine called a calcium channel blocker. This type of medicine acts on the heart and blood vessels. (NB. Nifedipine is also available without a brand name, ie as the generic medicine.)
Nifedipine works by slowing the movement of calcium through the muscle cells that are found in the walls of blood vessels. It does this by blocking 'calcium channels' in these muscle cells. Calcium is needed by muscle cells in order for them to contract, so by depriving them of calcium, nifedipine causes the muscle cells to relax.
Nifedipine acts specifically on the muscle cells in the walls of arteries, causing them to relax. This allows the arteries in the body to widen, an effect that has two main uses.
The relaxing and widening of the small arteries in the body decreases the resistance that the heart has to push against in order to pump the blood around the body. This reduces the pressure within the blood vessels. Nifedipine can therefore be used to lower high blood pressure.
The widening effect on the small arteries and the arteries in the heart also improves the blood and therefore oxygen supply to the heart. This feature means nifedipine can be used in the management of angina. The chest pain of angina is caused by insufficient oxygen supply to the heart. As nifedipine improves this oxygen supply, and also reduces the effort the heart has to make to pump blood, can be used to prevent angina attacks.
Nifedipine is also used to treat a circulatory disorder called Raynaud's phenomenon. In this condition the blood vessels in the hands go into spasm and contract excessively when the hands are cold. This causes the hands to go white, numb and painful. Nifedipine relaxes the peripheral arteries in the hands, causing them to widen and the blood circulation to the fingers to improve.
Nifedipine may be given in a form that has an effect as soon as the medicine is taken and then tapers off (described as immediate-release or short-acting), or in a form that releases the medicine slowly over the day (which may be described as controlled/slow/prolonged/extended/modified/sustained-release or long-acting). Adalat capsules are a short-acting form of nifedipine.
Short-acting forms of nifedipine such as Adalat capsules are usually only used to relieve the symptoms of Raynaud's. They may also be given in single doses to control high blood pressure, but are not recommended for the long-term treatment of high blood pressure or angina. This is because short-acting nifedipine can cause large variations in blood pressure and a reflex increase in heart rate. Long-acting forms of nifedipine are preferred for these conditions, because the steady release of the medicine doesn't cause this problem.
What if I miss a dose?
If you miss a dose, take it as soon as you can. If it is almost time for your next dose, take only that dose. Do not take double or extra doses.
Why should Adalat (Nifedipine) not be prescribed? Procardia should not be used if you have ever had an allergic reaction to it or are sensitive to it or other calcium channel blockers (Adalat (Nifedipine), Calan, others). Make sure your doctor is aware of any drug reactions you have experienced.
Special warnings about Procardia Procardia and Procardia XL may cause your blood pressure to become too low, which may make you feel light-headed or faint. This is more likely to happen when you start taking the medication and when the amount you take is increased. It is also more likely to occur if you are also taking a beta-blocker heart medication such as Tenormin or Inderal. Your doctor should check your blood pressure when you start taking Procardia or Procardia XL and continue monitoring it while your dosage is being adjusted. Procardia XL can be used for high blood pressure; plain Procardia should be used only for angina--NOT for high blood pressure. Do not take Procardia for the first week or two following a heart attack, or if you are in danger of a heart attack. There is a remote possibility of experiencing increased angina when you start taking Procardia or Procardia XL, or when your dosage is increased. If this happens, contact your doctor immediately.
