Mechanism of Action. This information should not be interpreted without the help of a healthcare provider. Nifedipine blocked all contractile activity. The absence of an interaction does not necessarily mean no interactions exist. Nifedipine is 3,5-pyridinedicarboxylic acid, 1,4-dihydro-2,6-dimethyl-4-(2-nitrophenyl)-, dimethyl ester, C17H18N2O6, and has the structural formula:Nifedipine is a yellow crystalline substance, practically insoluble in water but soluble in ethanol. If you have high blood pressure, taking nifedipine helps to prevent future heart disease, heart attacks and strokes.. Nifedipine is also used to prevent chest pain caused by angina.Occasionally, it's used to treat Raynaud's phenomenon and chilblains.. [2] In 2017, it was the 120th most commonly prescribed medication in the United States, with more than six million prescriptions. Nifedipine mechanism of action Inhibits the movement of calcium ions across cell membranes by blocking the entry of calcium into cells. In hypertension, recent clinical guidelines generally favour diuretics and ACE inhibitors, although calcium channel antagonists, along with thiazide diuretics, are still favoured as primary treatment for patients over 55 and black patients. The adverse effects include lethargy, bradycardia, marked hypotension and loss of consciousness. An effect category for each drug interaction. [, Lee TS, Kaku T, Takebayashi S, Uchino T, Miyamoto S, Hadama T, Perez-Reyes E, Ono K: Actions of mibefradil, efonidipine and nifedipine block of recombinant T- and L-type Ca channels with distinct inhibitory mechanisms. The mechanism by which nifedipine reduces arterial blood pressure involves peripheral arterial vasodilatation and, consequently, a reduction in peripheral vascular resistance. The increased peripheral vascular resistance, an underlying cause of hypertension, results from an increase in active tension in the vascular smooth muscle. Concomitant administration with strong CYP3A4 inducers (eg, rifampin, rifabutin, phenobarbital, phenytoin, carbamazepine, St John's wort) significantly reduces nifedipine efficacy. Nifedipine (10, 20, 30 mg] or placebo was ingested as capsules in a double-blind design on 4 separate days. The metabolism of Abemaciclib can be increased when combined with Nifedipine. Nifedipine's mechanism of action is through smooth-muscle relaxation secondary to blockage of the slow calcium channels into the cells. The mechanism by which nifedipine reduces arterial blood pressure involves peripheral arterial vasodilatation and, consequently, a reduction in peripheral vascular resistance. Nifedipine blocks voltage gated L-type calcium channels in … [2][3][4] It is on the World Health Organization's List of Essential Medicines. The medicine is only available on prescription. [medical citation needed] It is also used for the small subset of people with pulmonary hypertension. Multiple studies in women have demonstrated the effectiveness and safety of nifedipine as an antihypertensive. Consultant (Obstetrics) North Staffordshire Hospital, Stoke on Trent, UK. [. A 2005 meta-analysis showed modest benefits (33% decrease in attack severity, 2.8-5 reduction in absolute number of attacks per week); it does conclude that most included studies used low doses of nifedipine. [23], Nifedipine (initially BAY a1040) was developed by the German pharmaceutical company Bayer, with most initial studies being performed in the early 1970s. whole fruit, juice and rind), can significantly increase serum levels of nifedipine and may cause toxicity. Some of the side effects of nifedipine are predictable on the basis of its calcium channel blocking abilities. These two compounds interact in a … Br J Pharmacol. Nifedipine may also be used for purposes not listed in this medication guide. Know how this interaction affects the subject drug. 1986 May;38(5):399-400. doi: 10.1111/j.2042-7158.1986.tb04598.x. Nifedipine, or BAY a 1040, is a first generation dihydropyridine L-type calcium channel blocker, similar to nicardipine.3,10,11,13 Nifedipine was developed by Bayer and first described in the literature, along with other dihydropyridines, in 1972.11,12 Since nifedipine's development, second and third generation dihydropyridines have been developed with slower onsets and longer durations of action.10 The most popular of the third generation dihydropyridines is amlodipine.10, Nifedipine was granted FDA approval on 31 December 1981.13, Nifedipine capsules are indicated to treat vasospastic angina and chronic stable angina.13 Extended release tablets are indicated to treat vasospastic angina, chronic stable angina, and hypertension.14,15, Nifedipine is an inhibitor of L-type voltage gated calcium channels that reduces blood pressure and increases oxygen supply to the heart.1 Immediate release nifedipine's duration of action requires dosing 3 times daily.13 Nifedipine dosing is generally 10-120mg daily.13 Patients should be counselled regarding the risk of excessive hypotension, angina, and myocardial infarction.13, Nifedipine blocks voltage gated L-type calcium channels in vascular smooth muscle and myocardial cells.1 This blockage prevents the entry of calcium ions into cells during depolarization, reducing peripheral arterial vascular resistance and dilating coronary arteries.1 These actions reduce blood pressure and increase the supply of oxygen to the heart, alleviating angina.1, Sublingual dosing leads to a Cmax of 10ng/mL, with a Tmax of 50min, and an AUC of 25ng*h/mL.9 Oral dosing leads to a Cmax of 82ng/mL, with a Tmax of 28min, and an AUC of 152ng*h/mL.9, Nifedipine is a Biopharmaceutics Classification System Class II drug, meaning it has low solubility and high intestinal permeability.8 It is almost completely absorbed in the gastrointestinal tract but has a bioavilability of 45-68%, partly due to first pass metabolism.3,8, The steady state volume of distribution of nifedipine is 0.62-0.77L/kg and the volume of distribution of the central compartment is 0.25-0.29L/kg.3, Nifedipine is 92-98% protein bound in serum.13 Nifedipine is 97±12% bound in a 40g/L solution of pure albumin.2 Nifedipine is 51.4±5.9% protein bound in a 50mg/100mL solution of alpha-1-acid glycoprotein, and 75.5±3.5% protein bound in a 150mg/mL solution.2, Nifedipine is predominantly metabolized by CYP3A4.1,8,13,14,15 Nifedipine is predominantly metabolized to 2,6-dimethyl-4-(2-nitrophenyl)-5-methoxycarbonyl-pyridine-3-carboxylic acid, and then further metabolized to 2-hydroxymethyl-pyridine carboxylic acid.6 Nifedipine is also minorly metabolized to dehydronifedipine.7, Hover over products below to view reaction partners, Nifedipine is 60-80% recovered in the urine as inactive water soluble metabolites, and the rest is eliminated in the feces as metabolites.14, The terminal elimination half life of nifedipine is approximately 2 hours.3,8, The total body clearance of nifedipine is 450-700mL/min.3, The oral LD50 in rats is 1022mg/kg and in mice is 202mg/kg.16, Patients experiencing an overdose may present with hypotension, sinus node dysfunction, atrioventricular node dysfunction, and reflex tachycardia.4,5 Overdose may be managed by monitoring cardiovascular and respiratory function; elevating extremities; and administering vasopressors, fluids, and calcium infusions.13.

Nifedipine, sold under the brand name Adalat among others, is a calcium channel blocker medication used to manage angina, high blood pressure, Raynaud's phenomenon, and premature labor. The mechanism by which nifedipine reduces arterial blood pressure involves peripheral arterial vasodilatation and, consequently, a reduction in peripheral vascular resistance.

Drug Metab Rev. Nifedipine is a medicine used to treat high blood pressure.. Nifedipine inhibits the transmembrane influx of extracellular calcium ions into myocardial and vascular smooth muscle cells, causing dilatation of the main coronary and systemic arteries and decreasing myocardial contractility. Talk to your doctor before using this form of nifedipine if you have galactose intolerance, or severe problems with lactose (milk sugar). Nifedipine dilates the main coronary arteries and coronary arterioles, both in normal and Therapeutic doses range from 10-30 mg orally every 6-8 hours.
