Which is safer: nifedipine or norvasc (amlodipine)?

Which is safer: nifedipine or norvasc (amlodipine)?

Both: Both are safe when appropriately used. The main difference between the two is lipid solubility, and thus, time to onset. Nifedipine is water soluble and has reasonably quick onset, but also the levels will waver through the day. Amlodipine (or norvasc) is lipid soluble, takes about a week to ramp up in effect, and has a nice steady state effect. ...Read more

Due to unavaiaility of metoprolol+amlodipine 25/2.5 shifted to atenolol+nifedipine 50/20. Is it ok?

Due to unavaiaility of metoprolol+amlodipine 25/2.5 shifted to atenolol+nifedipine 50/20. Is it ok?

BP meds: It all depends on how the new drugs control your blood pressure. And also how the old drugs were doing. You need to keep a diary of pressures at various times during the day for about a week to make sure. And if you didn't do this while on the old meds, you have no idea how they were doing. Good luck. ...Read more

Due to unavaibility of metoprolol +amlodipine 25/2.5 in mauritania, I changed to atenolol+nifedipine. 50/20. Is it ok?

Due to unavaibility of metoprolol +amlodipine 25/2.5 in mauritania, I changed to atenolol+nifedipine. 50/20. Is it ok?

Somewhat comparable: Same drug classes at comparable doses.
Both atenolol and metoprolol are selective beta-1 blockers with similar effectiveness for BP control & prevention of cardiac events.
For calcium channel blockers, amlodipine is usually longer acting, but there are long-acting forms of nifedipine.
Your md made choice for a reason. No guarantee new combo will work as well, but it might even work better for you. ...Read more

Why is nifedipine not used for asthma?

Why is nifedipine not used for asthma?

Wrong site of action: Many meds work by acting on "receptors" on cell surfaces. Receptors trigger activity within cells, causing the intended effect. Intended receptors can be present in many parts of the body, or med may act on different receptors (both reasons for side effects, or multiple uses for same med). Nifedipine blocks certain calcium channels. Blocking these does not open the bronchi, so not helpful. ...Read more

How much time do nifedipine withdrawal symptoms last?

A few days: With these kinds of calcium channel blockers, it is not usually recommended that they be discontinued rapidly or at once. Tapering the dose down over a week can reduce the "rebound" symptoms - it is not truly a "withdrawal, " in the usual sense. If stopped abruptly, I have seen symptoms go on for a week, but they are usually only noticeable for 3-4 days. ...Read more

Don't stop abruptly: Stopping calcium channel blockers, particularly Nifedipine suddenly can not only cause withdrawal or "rebound" symptoms, it can dangerously elevate blood pressure and pulse to where it can cause harm. They should be tapered, or if you had a bad reaction, switched to another similar drug and that be tapered gradually. ...Read more

Why does procardia (nifedipine) cause edema?

Why does procardia (nifedipine) cause edema?

Ca++ channel blocker: The cause of edema in calcium channel blocker medications is due to the decrease in arteriolar resistance. The resistance change is not seen in the veins, so the pressure in the capillary beds is increased, thus causing fluid fluid shift into the tissues, resulting in edema. ...Read more

If your BP is OK, then wait til tomorrow and resume as usual. Perhaps a pillbox or a smartphone app may help you with med compliance in the future. ...Read more
