Pharmacology

Amlodipine: Directly acts on vascular smooth muscle to produce peripheral arterial vasodilation reducing peripheral vascular resistance and blood pressure.

Celecoxib: Inhibits prostaglandin synthesis by decreasing the activity of the enzyme, cyclooxygenase-2 (COX-2), which results in decreased formation of prostaglandin precursors; has antipyretic, analgesic, and anti-inflammatory properties.

Use: Labeled Indications

Hypertension and osteoarthritis: Management of hypertension in adults with osteoarthritis.

Limitations of use: Inappropriate for short-term or intermittent treatment or to treat any conditions other than hypertension in patients taking celecoxib for osteoarthritis.

Contraindications

Hypersensitivity (eg, anaphylactic reactions, serious skin reactions) to amlodipine, celecoxib, sulfonamides, or any component of the formulation; patients who have experienced asthma, urticaria, or other allergic-type reactions after taking aspirin or other NSAIDs; use in the setting of coronary artery bypass graft (CABG) surgery.

Note: Although the FDA approved product labeling states this medication is contraindicated with other sulfonamide-containing drug classes, the scientific basis of this statement has been challenged. See “Warnings/Precautions” for more detail.

These events can occur at any time during use and without warning symptoms. Elderly patients and patients with a prior history of peptic ulcer disease and/or GI bleeding are at greater risk for serious GI events.

Concerns related to adverse effects:

• Anaphylactoid reactions: Even in patients without prior exposure to celecoxib, anaphylactic reactions and angioedema may occur; patients with "aspirin triad" (bronchial asthma, aspirin intolerance, rhinitis) may be at increased risk. Contraindicated in patients who have experienced an anaphylactic reaction with NSAID or aspirin therapy.

• Angina/MI: Increased angina and/or MI have occurred with initiation or dosage titration of dihydropyridine calcium channel blockers. Reflex tachycardia may occur resulting in angina and/or MI in patients with obstructive coronary disease, especially in the absence of concurrent beta-blockade.

• Cardiovascular events: [US Boxed Warning]: NSAIDs cause an increased risk of serious (and potentially fatal) adverse cardiovascular thrombotic events, including MI and stroke. Risk may occur early during treatment and may increase with duration of use. Relative risk appears to be similar in those with and without known cardiovascular disease or risk factors for cardiovascular disease; however, absolute incidence of cardiovascular events (which may occur early during treatment) was higher in patients with known cardiovascular disease or risk factors. New onset hypertension or exacerbation of hypertension may occur (NSAIDs may also impair response to ACE inhibitors, thiazide diuretics, or loop diuretics); may contribute to cardiovascular events; monitor blood pressure; use with caution in patients with hypertension. May cause sodium and fluid retention; use with caution in patients with edema. Avoid use in patients with heart failure (ACC/AHA [Yancy 2013]). Avoid use in patients with recent MI unless benefits outweigh risk of cardiovascular thrombotic events. Use the lowest effective dose for the shortest duration of time, consistent with individual patient goals, to reduce risk of cardiovascular events; alternate therapies should be considered for patients at high risk. Symptomatic hypotension can occur with amlodipine.

• Gastrointestinal events: [US Boxed Warning]: NSAIDs cause an increased risk of serious gastrointestinal inflammation, ulceration, bleeding, and perforation (may be fatal); elderly patients and patients with history of peptic ulcer disease and/or GI bleeding are at greater risk for serious GI events. These events may occur at any time during therapy and without warning. Avoid use in patients with active GI bleeding. Use caution with a history of GI ulcers, concurrent therapy known to increase the risk of GI bleeding (eg, aspirin, anticoagulants and/or corticosteroids, selective serotonin reuptake inhibitors), smoking, use of alcohol, or in elderly or debilitated patients. Use the lowest effective dose for the shortest duration of time, consistent with individual patient goals, to reduce risk of GI adverse events; alternate therapies should be considered for patients at high risk. When used concomitantly with aspirin, a substantial increase in the risk of gastrointestinal complications (eg, ulcer) occurs; concomitant gastroprotective therapy (eg, proton pump inhibitors) is recommended (Bhatt 2008).

• Hematologic effects: Anemia may occur with celecoxib; monitor hemoglobin or hematocrit in patients on long-term treatment. Celecoxib does not usually affect PT, PTT or platelet counts; does not inhibit platelet aggregation at approved doses.

• Skin reactions: NSAIDs may cause serious skin adverse events including exfoliative dermatitis, Stevens-Johnson syndrome (SJS), and toxic epidermal necrolysis (TEN); may occur without warning and in patients without prior known sulfa allergy; discontinue use at first sign of rash (or any other hypersensitivity).

• Sulfonamide ("sulfa") allergy: The FDA-approved product labeling for many medications containing a sulfonamide chemical group includes a broad contraindication in patients with a prior allergic reaction to sulfonamides. There is a potential for cross-reactivity between members of a specific class (eg, two antibiotic sulfonamides). However, concerns for cross-reactivity have previously extended to all compounds containing the sulfonamide structure (SO2NH2). An expanded understanding of allergic mechanisms indicates cross-reactivity between antibiotic sulfonamides and nonantibiotic sulfonamides may not occur or at the very least this potential is extremely low (Brackett 2004; Johnson 2005; Slatore 2004; Tornero 2004). In particular, mechanisms of cross-reaction due to antibody production (anaphylaxis) are unlikely to occur with nonantibiotic sulfonamides. T-cell-mediated (type IV) reactions (eg, maculopapular rash) are less well understood and it is not possible to completely exclude this potential based on current insights. In cases where prior reactions were severe (Stevens-Johnson syndrome/TEN), some clinicians choose to avoid exposure to these classes.

Disease-related concerns:

• Aortic stenosis: Use amlodipine with extreme caution in patients with severe aortic stenosis; may reduce coronary perfusion resulting in ischemia.

• Asthma: The manufacturer’s labeling states to not administer to patients with aspirin-sensitive asthma due to severe and potentially fatal bronchospasm that has been reported in such patients having received aspirin and the potential for cross reactivity with other NSAIDs. The manufacturer also states to use with caution in patients with other forms of asthma. However, in patients with known aspirin-exacerbated respiratory disease (AERD), the use of celecoxib initiated at a low dose with gradual titration in patients with stable, mild to moderate persistent asthma has been used without incident (Morales 2013).

• Coronary artery bypass graft surgery: [US Boxed Warning]: Use is contraindicated in the setting of coronary artery bypass graft surgery (CABG). Risk of MI and stroke may be increased with use following CABG surgery.

• Cytochrome P450 isoenzyme 2C9 deficiency: Use is not recommended in patients with known or suspected deficiency of cytochrome P450 isoenzyme 2C9 (poor metabolizers may have higher plasma levels due to reduced metabolism).

• Hepatic impairment: Use is not recommended in patients with moderate to severe hepatic impairment. Transaminase elevations have been reported with celecoxib use; closely monitor patients with any abnormal LFT. Rare (sometimes fatal), severe hepatic reactions (eg, fulminant hepatitis, hepatic necrosis, hepatic failure) have occurred with NSAID use; discontinue if signs or symptoms of liver disease develop, if systemic manifestations occur, or with persistent or worsening abnormal hepatic function tests.

• Hypertrophic cardiomyopathy (HCM) with outflow tract obstruction: Use amlodipine with caution in patients with HCM and outflow tract obstruction since reduction in afterload may worsen symptoms associated with this condition (ACCF/AHA [Gersh 2011]).

• Renal impairment: NSAID use may compromise existing renal function. Dose-dependent decreases in prostaglandin synthesis may result from NSAID use, causing a reduction in renal blood flow which may cause renal decompensation (usually reversible). Patients with impaired renal function, dehydration, hypovolemia, heart failure, liver dysfunction, those taking diuretics, ACE inhibitors, angiotensin II receptor blockers, and the elderly are at greater risk for renal toxicity. Rehydrate patient before starting therapy; monitor renal function closely. Avoid use in patients with advanced renal disease; discontinue use with persistent or worsening abnormal renal function tests. Long-term NSAID use may result in renal papillary necrosis.

Concurrent drug therapy issues:

• Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information.

Monitoring Parameters

Blood pressure, heart rate; CBC; hemoglobin/hematocrit (anemic patients); basic metabolic panel; occult blood loss; liver function tests; renal function; observe for weight gain, edema; observe for bleeding, bruising; evaluate GI effects (abdominal pain, bleeding, dyspepsia)

Pregnancy Considerations

Amlodipine crosses the placenta (Morgan 2017).

Because NSAIDs may cause premature closure of the ductus arteriosus, celecoxib should be avoided starting at 30 weeks' gestation

The chronic use of NSAIDs in women of reproductive age may be associated with infertility that is reversible upon discontinuation of the medication. Consider discontinuing use in women having difficulty conceiving or those undergoing investigation of fertility.

Patient Education

• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)

• Patient may experience headache, abdominal pain, heartburn, diarrhea, flatulence, fatigue, flushing, or common cold symptoms. Have patient report immediately to prescriber signs of bowel problems (black, tarry, or bloody stools; fever; mucus in stools; vomiting; vomiting blood; severe abdominal pain; constipation; or diarrhea), signs of liver problems (dark urine, fatigue, lack of appetite, nausea, abdominal pain, light-colored stools, vomiting, or jaundice), signs of bleeding (vomiting blood or vomit that looks like coffee grounds; coughing up blood; hematuria; black, red, or tarry stools; bleeding from the gums; abnormal vaginal bleeding; bruises without a reason or that get bigger; or any severe or persistent bleeding), signs of kidney problems (urinary retention, hematuria, change in amount of urine passed, or weight gain), signs of high potassium (abnormal heartbeat, confusion, dizziness, passing out, weakness, shortness of breath, or numbness or tingling feeling), signs of severe cerebrovascular disease (change in strength on one side is greater than the other, difficulty speaking or thinking, change in balance, or vision changes), severe headache, dizziness, passing out, vision changes, shortness of breath, excessive weight gain, swelling of arms or legs, chest pain, severe loss of strength and energy, joint edema, polyuria, or signs of Stevens-Johnson syndrome/toxic epidermal necrolysis (red, swollen, blistered, or peeling skin [with or without fever]; red or irritated eyes; or sores in mouth, throat, nose, or eyes) (HCAHPS).

• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
