| ==Use in Specific Populations==
| |
| | |
| ===Pregnancy:===
| |
| | |
| ===Pregnancy Category C.===
| |

| '''Teratogenic Effects''' – Studies in pregnant rabbits administered doses of 0.46, 1.2, 2.3, and 4.6 mg/kg/day (from 0.8 to 8 times1 the maximum recommended human dose on a mg/m2 basis) showed digital anomalies consisting of reduction in size and degree of ossification of the terminal phalanges in the fetuses. The frequency and severity of the changes appeared dose related and were noted even at the lowest dose. These changes have been shown to occur with other members of the [[dihydropyridine]] class and are possibly a result of compromised uterine blood flow. Similar fetal anomalies were not observed in rats given felodipine.
| |
| | |
| In a teratology study in cynomolgus monkeys, no reduction in the size of the terminal phalanges was observed, but an abnormal position of the distal phalanges was noted in about 40% of the fetuses.
| |
| | |
| '''Nonteratogenic Effects''' – A prolongation of parturition with difficult labor and an increased frequency of fetal and early postnatal deaths were observed in rats administered doses of 9.6 mg/kg/day (8 times1 the maximum human dose on a mg/m2 basis) and above.
| |
| | |
| Significant enlargement of the mammary glands, in excess of the normal enlargement for pregnant rabbits, was found with doses greater than or equal to 1.2 mg/kg/day (2.1 times the maximum human dose on a mg/m2 basis). This effect occurred only in pregnant rabbits and regressed during lactation.
| |
| | |
| Similar changes in the mammary glands were not observed in rats or monkeys.
| |
| | |
| There are no adequate and well-controlled studies in pregnant women. If felodipine is used during pregnancy, or if the patient becomes pregnant while taking this drug, she should be apprised of the potential hazard to the fetus, possible digital anomalies of the infant, and the potential effects of felodipine on labor and delivery and on the mammary glands of pregnant females.
| |
| | |
| ===Nursing Mothers===
| |
| | |
| It is not known whether this drug is secreted in human milk and because of the potential for serious adverse reactions from felodipine in the infant, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.
| |
| | |
| ===Pediatric Use===
| |
| | |
| Safety and effectiveness in pediatric patients have not been established.
| |
| | |
| ===Geriatric Use:===
| |
| | |
| Clinical studies of felodipine did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. Pharmacokinetics, however, indicate that the availability of felodipine is increased in older patients (see CLINICAL PHARMACOLOGY, Geriatric Use). In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.<ref name="dailymed.nlm.nih.gov">{{Cite web | last = | first = | title = PLENDIL (FELODIPINE) TABLET, EXTENDED RELEASE [ASTRAZENECA LP] | url = http://dailymed.nlm.nih.gov/dailymed/lookup.cfm?setid=2aad9cdf-6431-4661-5cb4-f69e735f47e4 | publisher = | date = | accessdate = 28 February 2014 }}</ref>
