Felodipine, sold under the brand name Plendil among others, is a medication is used to treat high blood pressure and heart related chest pain (angina).[1][2] It is one of several first line options.[1] It is taken by mouth.[1]

Common side effects include swelling, headache, and flushing.[1] Other side effects may include syncope and low blood pressure.[1] There are concerns regarding negative effects if used during pregnancy.[5] It is a calcium channel blocker of the dihydropyridine type.[1]

Felodipine was patented in 1978 and approved for medical use in 1988.[6] It is available as a generic medication.[2] In the United Kingdom 4 weeks of 5 mg per day costs about £4 as of 2021.[2] This amount is about 11 USD in the United States.[7] It is also available in combination with ramipril.[2]

## Medical uses[edit | edit source]

Felodipine is used to treat high blood pressure and stable angina.[3][8]

It should not be used for people who are pregnant, have acute heart failure, are having a heart attack, have an obstructed heart valve, or have obstructions that block bloodflow out of the heart.[3]

For people with liver failure the dose needs to be lowered, because felodipine is cleared by the liver.[3]

### Dosage[edit | edit source]

It is generally started at 5 mg per day and may be increased to 10 mg per day if needed.[2] In the elderly 2.5 mg per day may be used.[2]

## Side effects[edit | edit source]

Gum enlargement due to felodipine

The only very common side effect, occurring in more than 1/10 people, is pain and swelling in the arms and legs.[3]

Common side effects, occurring in between 1% and 10% of people, include flushing, headache, heart palpitations, dizziness and fatigue.[3]

Felodipine can exacerbate gingivitis.[3]

## Interactions[edit | edit source]

Felodipine is metabolized by cytochrome P450 3A4, so substances that inhibit or activate CYP3A4 can strongly effect how much felodipine is present.[3]

CYP3A4 inhibitors, which increase the amount of felodipine available per dose, include cimetidine, erythromycin, itraconazole, ketoconazole, HIV protease inhibitors, and grapefruit juice.[3][9]

CYP3A4 activators, which decrease the amount of felodipine available per dose, include phenytoin, carbamazepine, rifampicin, barbiturates, efavirenz, nevirapine, and Saint John's wort.[3]

## Mechanism of action[edit | edit source]

Felodipine is a calcium channel blocker.[3] Felodipine has additionally been found to act as an antagonist of the mineralocorticoid receptor, or as an antimineralocorticoid.[10]

Different calcium channels are present in vascular tissue and cardiac tissue; an in vitro study on human vascular and cardiac tissues comparing how selective various calcium channel blockers are for vascular compared to cardiac tissue found the following vascular/cardiac tissue ratios: mibefradil 41, felodipine 12; nifedipine 7, amlodipine 5, and verapamil 0.2.[11]: 172

## Chemistry[edit | edit source]

Felodipine is a member of the 1,4-dihydropyridine class of calcium channel blockers.[11]: 20–21 It is a racemic mixture, and is insoluble in water but is soluble in dichloromethane and ethanol.[11]: 25

## History[edit | edit source]

The Swedish company Hässle, a division of Astra AB, discovered felodipine;[12] it filed a patent application in 1979 claiming felodipine as an antihypertensive drug.[13][14] Astra partnered this drug and others with Merck & Co. in the US under a 1982 agreement between the companies.[12] The drug was approved by the FDA in 1991 after a three and a half year review; the drug entered a very crowded market the included the other calcium channel blockers nifedipine, verapamil, nicardipine, and isradipine.[12] The FDA gave the drug a 1C rating, meaning that it found little difference between felodipine and the drugs already approved for the same use.[12]

In 1994 Astra AB and Merck changed their partnership to a joint venture called Astra Merck,[15] and in 1998 Astra (by that time, AstraZeneca) bought out Merck's rights in the joint venture.[16]

The first generics became available in Sweden in 2003[17] and in the US in 2004.[18]: 155

In April 2016, AstraZeneca announced that they were selling the right to market felodipine in China to China Medical System Holdings for $310 million; AZ would continue to manufacture the drug.[19]
