INDICATIONS & USAGE I. Vasospastic Angina Nifedipine extended-release tablets are indicated for the management of vasospastic angina confirmed by any of the following criteria: 1) classical pattern of angina at rest accompanied by ST segment elevation, 2) angina or coronary artery spasm provoked by ergonovine, or 3) angiographically demonstrated coronary artery spasm. In those patients who have had angiography, the presence of significant fixed obstructive disease is not incompatible with the diagnosis of vasospastic angina, provided that the above criteria are satisfied. Nifedipine extended-release tablets may also be used where the clinical presentation suggests a possible vasospastic component, but where vasospasm has not been confirmed, e.g., where pain has a variable threshold on exertion, or in unstable angina where electrocardiographic findings are compatible with intermittent vasospasm, or when angina is refractory to nitrates and/or adequate doses of beta blockers. II. Chronic Stable Angina (Classical Effort-Associated Angina) Nifedipine extended-release tablets are indicated for the management of chronic stable angina (effort-associated angina) without evidence of vasospasm in patients who remain symptomatic despite adequate doses of beta blockers and/or organic nitrates or who cannot tolerate those agents. In chronic stable angina (effort-associated angina), nifedipine has been effective in controlled trials of up to eight weeks duration in reducing angina frequency and increasing exercise tolerance, but confirmation of sustained effectiveness and evaluation of long-term safety in these patients is incomplete. Controlled studies in small numbers of patients suggest concomitant use of nifedipine and beta-blocking agents may be beneficial in patients with chronic stable angina, but available information is not sufficient to predict with confidence the effects of concurrent treatment, especially in patients with compromised left ventricular function or cardiac conduction abnormalities. When introducing such concomitant therapy, care must be taken to monitor blood pressure closely, since severe hypotension can occur from the combined effects of the drugs. (See WARNINGS ) III. Hypertension Nifedipine extended-release tablets are indicated for the treatment of hypertension, to lower blood pressure. Lowering blood pressure reduces the risk of fatal and nonfatal cardiovascular events, primarily strokes and myocardial infarctions....

DOSAGE & ADMINISTRATION Dosage must be adjusted according to each patient’s needs. Therapy for either hypertension or angina should be initiated with 30 or 60 mg once daily. Nifedipine Extended-Release Tablets USP should be swallowed whole and should not be bitten or divided. In general, titration should proceed over a 7 to 14 day period so that the physician can fully assess the response to each dose level and monitor blood pressure before proceeding to higher doses. Since steady-state plasma levels are achieved on the second day of dosing, titration may proceed more rapidly, if symptoms so warrant, provided the patient is assessed frequently. Titration to doses above 120 mg are not recommended. Angina patients controlled on nifedipine capsules alone or in combination with other antianginal medications may be safely switched to nifedipine extended-release tablets at the nearest equivalent total daily dose (e.g., 30 mg t.i.d. of nifedipine capsules may be changed to 90 mg once daily of nifedipine extended-release tablets). Subsequent titration to higher or lower doses may be necessary and should be initiated as clinically warranted. Experience with doses greater than 90 mg in patients with angina is limited. Therefore, doses greater than 90 mg should be used with caution and only when clinically warranted. Avoid coadministration of nifedipine with grapefruit juice (see CLINICAL PHARMACOLOGY and PRECAUTIONS: Other Interactions ). No “rebound effect” has been observed upon discontinuation of nifedipine extended-release tablets. However, if discontinuation of nifedipine is necessary, sound clinical practice suggests that the dosage should be decreased gradually with close physician supervision. Care should be taken when dispensing nifedipine extended-release tablets to assure that the extended release dosage form has been prescribed. Coadministration with Other Antianginal Drugs Sublingual nitroglycerin may be taken as required for the control of acute manifestations of angina, particularly during nifedipine titration. See PRECAUTIONS, , for information on coadministration of nifedipine with beta blockers or long-acting nitrates.

ADVERSE EXPERIENCES Over 1000 patients from both controlled and open trials with nifedipine extended-release tablets in hypertension and angina were included in the evaluation of adverse experiences. All side effects reported during nifedipine extended-release tablets therapy were tabulated independent of their causal relation to medication. The most common side effect reported with nifedipine extended-release tablets was edema which was dose related and ranged in frequency from approximately 10% to about 30% at the highest dose studied (180 mg). Other common adverse experiences reported in placebo-controlled trials include: Nifedipine Extended-Release Tablets (%) (N=707) Placebo (%) (N=266) Adverse Effect Headache 15.8 9.8 Fatigue 5.9 4.1 Dizziness 4.1 4.5 Constipation 3.3 2.3 Nausea 3.3 1.9 Of these, only edema and headache were more common in nifedipine extended-release tablets patients than placebo patients. The following occurred with an incidence of less than 3.0%. With the exception of leg cramps, the incidence of these side effects was similar to that of placebo alone. Body as a Whole/Systemic: asthenia, flushing, pain Cardiovascular: palpitations Central Nervous System: insomnia, nervousness, paresthesia, somnolence Dermatologic: pruritus, rash Gastrointestinal: abdominal pain, diarrhea, dry mouth, dyspepsia, flatulence Musculoskeletal: arthralgia, leg cramps Respiratory: chest pain (nonspecific), dyspnea Urogenital: impotence, polyuria Other were reported sporadically with an incidence of 1.0% or less. These include: Body as a Whole/Systemic: face edema, fever, hot flashes, malaise, periorbital edema, rigors Cardiovascular: arrhythmia, hypotension, increased angina, tachycardia, syncope Central Nervous System: anxiety, ataxia, decreased libido, depression, hypertonia, hypoesthesia, migraine, paroniria, tremor, vertigo Dermatologic: alopecia, increased sweating, urticaria, purpura Gastrointestinal: eructation, gastroesophageal reflux, gum hyperplasia, melena, vomiting, weight increase Musculoskeletal: back pain, gout, myalgias Respiratory: coughing, epistaxis, upper respiratory tract infection, respiratory disorder, sinusitis Special Senses: abnormal lacrimation, abnormal vision, taste perversion, tinnitus Urogenital/Reproductive: breast pain, dysuria, hematuria, nocturia Adverse experiences which occurred in less than 1 in 1000 patients cannot be distinguished from concurrent disease states or medications....
