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. It was once frequently prescribed on an as-needed basis to patients taking MAOIs for real or perceived hypertensive crises. Clin Cardiol. Epub 2015 Aug 10. The serum concentration of Nifedipine can be increased when it is combined with Abametapir. [2] Its use in preterm labor may allow more time for steroids to improve the baby's lung function and provide time for transfer of the mother to a well qualified medical facility before delivery. It may be used to treat severe high blood pressure in pregnancy. Although nifedipine and other dihydropyridines are commonly regarded as specific to the L-type calcium channel, they also possess nonspecific activity towards other voltage-dependent calcium channels. doi: 10.1002/prp2.161.

Grapefruit down-regulates post-translational expression of CYP3A4, the major metabolizing enzyme of nifedipine.

Ca 2+ channel blockers. [19][20], Nifedipine is a calcium channel blocker. These problems are much less frequent in the sustained-release preparations of nifedipine.

Procardia® (nifedipine) is an antianginal drug belonging to a class of pharmacological agents, the calcium channel blockers. The contractile processes of cardiac muscle and vascular smooth muscle are dependent upon the movement of extracellular calcium ions into these cells through specific ion channels. (2004).

Nifedipine inhibits lower esophageal (LES) muscle contraction by blocking cellular calcium uptake and lowers the LES resting pressure by 30% to 60%; side effects (e.g., hypotension, headache, dizziness) and tolerance may limit its utility. 2016 Jul;18(4):981-8. doi: 10.1208/s12248-016-9918-x.
