Why is nifedipine no longer used

Nifedipine is a dihydropyridine calcium channel blocker, the short acting formulation of which has been associated with reflex sympathetic nervous system (SNS) activation leading to flushing, tachycardia, worsening myocardial ischemia, and cerebrovascular ischemia; therefore only longer acting formulations should be used (Gibbons et al 2003) The use of nisoldipine (10-20 mg b.i.d.) was evaluated as a replacement therapy for long-acting nifedipine (40-120 mg/day) in 21 patients with severe hypertension, who were resistant to or intolerant of nifedipine. Except for one patient with specific contraindications, all participants received an Nifedipine was previously available as immediate-release (IR) capsules sold under the brand name Adalat, but both strengths were discontinued by March 2019

Nifedipine is a calcium channel blocker in the dihydropyridine subclass. It is primarily used as an antihypertensive and as an anti-anginal medication. FDA-approved indications include chronic stable angina, hypertension. It also has other off-label indications. This activity outlines the indications, mechanism of action, methods of administration, important adverse effects, contraindications. Nifedipine. Nifedipine is a predominant arteriolar vasodilator, with minimal effect on venous capacitance vessels and no direct depressant effect on heart rate conduction. It may be administered intravenously, orally or sublingually, and has a rapid onset of action (2-5 minutes) and duration of action of 20-30 minutes

  1. Use in Essential Hypertension . PROCARDIA and other immediate-release nifedipine capsules have also been used for the long-term control of essential hypertension, although PROCARDIA capsules have not been approved for this purpose and no properly controlled studies have been conducted to define an appropriate dose or dose interval for such.
  2. Nifedipine is one of the most widely used and studied medications among the calcium-channel blockers to suppress preterm contractions. longer use of tocolytics has no apparent benefit.
  3. Nifedipine is used in the treatment of vasospastic angina and occasionally for chronic unstable angina as an add-on to other treatments. Nifedipine should not be used to rapidly drop blood pressure as this may be fatal and it should not be taken with grapefruit juice or grapefruit products. 5. Tips. May be taken with or without food

Nifedipine is in a group of drugs called calcium channel blockers. It works by relaxing the muscles of your heart and blood vessels. Nifedipine is used to treat hypertension (high blood pressure) and angina (chest pain). Nifedipine may also be used for purposes not listed in this medication guide Nifedipine is an oral medication used to treat hypertension (high blood pressure). Learn about side effects, warnings, dosage, and more The use of short-acting nifedipine is no longer considered appropriate because it can cause a rapid unpredictable fall in blood pressure and may precipitate ischemic events. Nifedipine is used to treat hypertension (high blood pressure) and angina (chest pain) Updated 23 September 2020. The Australian suppliers of immediate release nifedipine have discontinued 10mg and 20mg tablets from the Australian market. It is suggested that RANZCOG members contact the Director of Pharmacy at the hospital they attend for information regarding availability and quality of immediate release nifedipine Descriptions. Nifedipine is used alone or together with other medicines to treat severe chest pain (angina) or high blood pressure (hypertension). High blood pressure adds to the workload of the heart and arteries. If it continues for a long time, the heart and arteries may not function properly. This can damage the blood vessels of the brain.

It is no longer common: I have always assumed it was more frequent in archaic usage. What interests me, though, is why it has persisted only for certain trades. For example, we still say (at least in the UK) fishmonger for someone who sells fish and (more rarely) ironmonger for someone that sells metal items and tools Because nifedipine is metabolized via the cytochrome P450 3A4 system, its pharmacokinetics may be altered in patients with chronic liver disease. Adalat CC has not been studied in patients with hepatic disease; however, in patients with hepatic impairment (liver cirrhosis) nifedipine has a longer elimination half-lif Nifedipine is a yellow crystalline substance, practically insoluble in water but soluble in ethanol.

Inert ingredients in the 30mg nifedipine extended-release tablet formulation are lactose.

Nifedipine is used to treat high blood pressure and to control angina (chest pain). Nifedipine is in a class of medications called calcium-channel blockers. It lowers blood pressure by relaxing the blood vessels so the heart does not have to pump as hard. It controls chest pain by increasing the supply of blood and oxygen to the heart Children—Use and dose must be determined by your doctor. For oral dosage form (extended-release tablets): Adults—At first, 30 or 60 milligrams (mg) once a day. Your doctor may increase your dose as needed. However, the dose is usually not more than 90 mg once a day. Children—Use and dose must be determined by your doctor. Missed Dos The danger of excess nifedipine-induced hypotension is that it increases myocardial ischemic damage and infarct size, as shown experimentally by Selwyn et al. 10 Nifedipine, as given in several of the trials shown in the Table of the article by Furberg et al, 2 appears to have been used without adequate cognizance of the fact that it is a.

Characteristics of three different calcium antagonist groups: Most important calcium antagonists used to treat cardiovascular disease belong to one of three main groups, phenylalkylamines, dihydropyridines and benzothiazepines. The best known drug in each group is verapamil, nifedipine and diltiazem The maintenance dose is 20 mg PO q 8 hours for 24 hours, or longer, depending on prescription. If contractions continue 60 minutes after the initial dose, nifedipine therapy should be considered a failure. A different tocolytic agent may be considered.

In 1989, longer-acting nifedipine formulations became available; several investigators 12-15 have since suggested that longer-acting preparations might have sufficiently different pharmacodynamic properties so as to result in lower mortality rates. We had limited information regarding the specific formulation of the nifedipine that our patients.
  3. Dihydropyridines, especially short acting nifedipine, can cause a reflex tachycardia secondary to arterial vasodilation and stimulation of the sympathetic nervous system.

Older people can also be more sensitive to certain medications Reviewed Nifedipine on 12/23/2016 I come from a long line of people with chronic hypertension. I was first prescribed Procardia XL during pregnancy, when Aldomet no longer worked to regulate my blood pressure and Labetalol gave me debilitating headaches. My youngest child is now five and I'm still happily taking Procardia XL 30 mg When we have to give nifedipine, we puncture the capsule with a blunt tip needle and draw out the liquid medication. We know from our drug books that a 10 mg capsule has 0.34 mL of liquid in it, so we do our drug calculation and dilute it to make the concentration 1:1 with NS (for example, draw up 0.17 and mix with 5 mL of NS) so that it easier.

Generally, long- rather than short-acting formulations of CCBs should be used given the ease of administration and better safety profile of longer-acting CCBs. Effective doses of amlodipine range from 5 to 20 mg/day, and effective doses of long-acting nifedipine range from 30 to 120 mg/day We conducted a study several years ago comparing amlodipine (an intrinsically long-acting dihydropyridine CCB) with short-acting nifedipine and the long-acting nifedipine GITS formulation. Somewhat surprisingly, we found that although amlodipine lowered BP slowly, it could activate the sympathetic nervous system when used chronically over 2 months Nifedipine sustained-action - oral.
