Moderate:

methylPREDNISolone somapacitan

Applies to: Duralone (methylprednisolone) and somapacitan
Monitor

Human growth hormone (hGH) may reduce the pharmacologic effects of corticosteroids. Growth hormone (GH) may alter the clearance of drugs metabolized by CYP450 (including 3A4), which could result in lower exposure to the corticosteroid in question. However, the clinical significance of the alteration in CYP450 activity is unknown. In addition, GH inhibits microsomal enzyme 11-beta-hydroxysteroid dehydrogenase type 1 (11BHSD-1), which is required for conversion of cortisone to its active metabolite, cortisol, in hepatic and adipose tissue. Consequently, individuals with untreated GH deficiency have relative increases in 11BHSD-1 and serum cortisol, and initiation of GH therapy may result in inhibition of 11BHSD-1 and reduced serum cortisol levels. Previously undiagnosed central (secondary) hypoadrenalism may be unmasked and glucocorticoid replacement may be required. In patients treated with glucocorticoid replacement for previously diagnosed hypoadrenalism, an increase in their maintenance or stress doses may be required following initiation of GH treatment. Cortisone acetate and prednisone may be affected more than others because conversion to their biologically active metabolites, cortisol and prednisolone, respectively, is dependent on the activity of 11BHSD-1.

Monitor

Treatment with pharmacologic and supraphysiologic glucocorticoid dosages may attenuate the growth promoting effects of human growth hormone in children due to inhibition of the hypothalamic-pituitary-adrenal axis.

Management

Higher dosages of corticosteroids may be required during concomitant use of human growth hormone. Patients treated with glucocorticoid replacement for previously diagnosed hypoadrenalism may require an increase in their maintenance or stress doses following initiation of GH treatment. In addition, glucocorticoid replacement dosing should be carefully adjusted in children receiving concomitant GH treatment to avoid both hypoadrenalism and an inhibitory effect on growth.

Food/lifestyle interactions

Moderate food/lifestyle interactions

Moderate:

methylPREDNISolone Food/Lifestyle

Applies to: Duralone (methylprednisolone)
Monitor

Concomitant use of systemic corticosteroids (e.g., prednisolone) with alcohol or products containing alcohol may increase gastrointestinal irritation and the risk of ulceration and bleeding. The proposed mechanism has not been fully elucidated but may involve additive mucosal irritation.

Monitor

Coadministration with grapefruit or grapefruit juice may increase the plasma concentrations of systemic corticosteroids. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruit. In general, the effect of grapefruit juice is concentration-, dose- and preparation-dependent, and can vary widely among brands. Certain preparations of grapefruit juice (e.g., high dose, double strength) have sometimes demonstrated potent inhibition of CYP450 3A4, while other preparations (e.g., low dose, single strength) have typically demonstrated moderate inhibition. Pharmacokinetic interactions involving grapefruit juice are also subject to a high degree of interpatient variability, thus the extent to which a given patient may be affected is difficult to predict.

Management

Caution is advised if corticosteroids and alcohol are used together, especially in patients with a prior history of peptic ulcer disease or gastrointestinal bleeding. Patients should be advised to report signs and symptoms of gastrointestinal ulceration and/or bleeding such as severe abdominal pain, dizziness, lightheadedness, and the appearance of black, tarry stools. Patients who regularly consume grapefruit or grapefruit juice should be monitored for adverse effects and for changes in corticosteroid plasma concentrations.

Therapy with corticosteroids should be administered cautiously in patients who have or may be predisposed to thrombotic or thromboembolic disorders.

History, Tuberculosis

Moderate:

Duralone

The methylPREDNISolone in Duralone has a moderate potential interaction with History, Tuberculosis.

In patients with latent tuberculosis or tuberculin reactivity, the use of pharmacologic dosages of corticosteroids may cause a reactivation of the disease. Close monitoring for signs and symptoms of tuberculosis is recommended if corticosteroid therapy is administered to patients with a history of tuberculosis or tuberculin reactivity. During prolonged corticosteroid therapy, tuberculosis chemoprophylaxis may be considered.

Hyperadrenocorticism

Moderate:

Duralone

The methylPREDNISolone in Duralone has a moderate potential interaction with Hyperadrenocorticism.

Corticosteroids mimic the effects of endogenous cortisol and aldosterone. Use of these agents may aggravate conditions of hyperadrenocorticalism in a dose-dependent manner.

Caution is also advised when treating patients with seizure disorders, since electrolyte disturbances may trigger seizure activity.

Infection

Major:

Duralone

The methylPREDNISolone in Duralone has a major potential interaction with Infection.

The immunosuppressant and anti-inflammatory effects of corticosteroids, particularly at higher dosages, may reduce resistance to infectious agents, increase the risk of disseminated infections, mask symptoms of infection, and reactivate or exacerbate latent/resolved infections; fatal cases have been reported. Avoid use of corticosteroids in patients with cerebral malaria. Screen patients for active (or history of) infection with tuberculosis, hepatitis, varicella, measles, and amebiasis, especially prior to prolonged treatment. Closely monitor for reactivation of latent infections; chemoprophylaxis may be required. In general, corticosteroids should not be used in patients with active infections, especially systemic fungal infections, unless medically necessary to control drug reactions. However, for corticosteroid-dependent patients who develop a severe or life-threatening infection, continuation of corticosteroid therapy with at least physiologic replacement dosages should be considered, since these patients may have secondary adrenocortical insufficiency. Removal of external steroid during periods of stress may be detrimental to these patients.

Intestinal Anastomoses

There is an increased risk of a second neoplasm in childhood cancer survivors treated with somatropin, in particular meningiomas in patients treated with radiation to the head for their first neoplasm. Children with certain rare genetic causes of short stature have an increased risk of developing malignancies, so thoroughly consider the risks and benefits of starting somapacitan in these patients. If treatment is initiated, carefully monitor these patients for development of neoplasms. There is risk of malignant changes of preexisting nevi with somatropin treatment. Monitor patients on therapy carefully for increased growth or potential malignant changes of preexisting nevi. Advise patients/caregivers to report marked changes in behavior, onset of headaches, vision disturbances, and/or changes in the appearance of preexisting nevi.

Multiple Endocrine Neoplasia Type II

Major:

Myasthenia Gravis

Moderate:

Duralone

The methylPREDNISolone in Duralone has a moderate potential interaction with Myasthenia Gravis.

Although corticosteroids are commonly used in the treatment of myasthenia gravis to increase muscle strength, these agents should nevertheless be administered with caution in such setting. Patients should be treated in an intensive care unit and receive respiratory support, since muscle strength may markedly decrease initially, particularly with high dosages. Preferably, therapy should begin with relatively low dosages (15 to 25 mg/day of prednisone or equivalent) and be increased stepwise as tolerated (approximately 5 mg/day of prednisone or equivalent at 2- to 3-day intervals until marked clinical improvement or a dosage of 50 mg/day is reached). Improvement may be delayed and gradual. Thus, it is important not to discontinue therapy prematurely.

Myoneural Disorder

Moderate:

Duralone

The methylPREDNISolone in Duralone has a moderate potential interaction with Myoneural Disorder.

Toxic myopathy has been observed with the chronic use or the administration of large doses of corticosteroids, often in patients with disorders of neuromuscular transmission such as myasthenia gravis or in patients receiving neuromuscular blocking agents. Fluorinated corticosteroids such as betamethasone, dexamethasone, and triamcinolone appear to cause more severe muscle atrophy and weakness than the nonfluorinated agents. Moreover, multiple-daily doses are more toxic than once-daily or, preferably, alternate-day morning doses. Steroid myopathy is generalized and sometimes accompanied by respiratory weakness and dyspnea. In some cases, it has resulted in quadriparesis. Elevations of creatine kinase (CK) may also occur, albeit infrequently. After withdrawal of corticosteroid therapy, recovery may be slow and incomplete. Therapy with corticosteroids should be administered cautiously in patients with preexisting myopathy or myoneural disorders since these conditions may confound the diagnosis of steroid-induced myopathy. The presence of a normal serum CK level, minimal/no changes of myopathy on electromyography, and type 2 muscle fiber atrophy on biopsy are helpful in suggesting steroid-induced weakness. If steroid myopathy is suspected, a dosage reduction or discontinuation of the steroid should be considered.

Myopathy

Moderate:

Duralone

The methylPREDNISolone in Duralone has a moderate potential interaction with Myopathy.

Toxic myopathy has been observed with the chronic use or the administration of large doses of corticosteroids, often in patients with disorders of neuromuscular transmission such as myasthenia gravis or in patients receiving neuromuscular blocking agents. Fluorinated corticosteroids such as betamethasone, dexamethasone, and triamcinolone appear to cause more severe muscle atrophy and weakness than the nonfluorinated agents. Moreover, multiple-daily doses are more toxic than once-daily or, preferably, alternate-day morning doses. Steroid myopathy is generalized and sometimes accompanied by respiratory weakness and dyspnea. In some cases, it has resulted in quadriparesis. Elevations of creatine kinase (CK) may also occur, albeit infrequently. After withdrawal of corticosteroid therapy, recovery may be slow and incomplete. Therapy with corticosteroids should be administered cautiously in patients with preexisting myopathy or myoneural disorders since these conditions may confound the diagnosis of steroid-induced myopathy. The presence of a normal serum CK level, minimal/no changes of myopathy on electromyography, and type 2 muscle fiber atrophy on biopsy are helpful in suggesting steroid-induced weakness. If steroid myopathy is suspected, a dosage reduction or discontinuation of the steroid should be considered.

Neoplasia, Estrogen Dependent

Major:

somapacitan

Somapacitan has a major potential interaction with Neoplasia, Estrogen Dependent.

Somapacitan is contraindicated in patients with active malignancies. There is an increased risk of neoplasm when using this drug. Monitor closely patients with preexisting tumors for progression or recurrence. There is an increased risk of a second neoplasm in childhood cancer survivors treated with somatropin, in particular meningiomas in patients treated with radiation to the head for their first neoplasm. Children with certain rare genetic causes of short stature have an increased risk of developing malignancies, so thoroughly consider the risks and benefits of starting somapacitan in these patients. If treatment is initiated, carefully monitor these patients for development of neoplasms. There is risk of malignant changes of preexisting nevi with somatropin treatment. Monitor patients on therapy carefully for increased growth or potential malignant changes of preexisting nevi. Advise patients/caregivers to report marked changes in behavior, onset of headaches, vision disturbances, and/or changes in the appearance of preexisting nevi.

Osteoporosis

Moderate:

Duralone

The methylPREDNISolone in Duralone has a moderate potential interaction with Osteoporosis.

Corticosteroids reduce osteoblastic function and inhibit the absorption of intestinal calcium, which can result in bone resorption and bone loss during prolonged therapy. In addition, bone matrix may be affected by the protein-catabolic effects of corticosteroids, especially when given in high dosages or for prolonged periods, leading to aseptic necrosis and fractures. Long-term or high-dose corticosteroid therapy should be administered cautiously and only if necessary in patients with or at risk for osteoporosis. Adverse skeletal effects may be minimized by alternate-day or intermittent administration. Any patient receiving prolonged therapy with the equivalent of 7.5 mg prednisone/day or more are at risk for glucocorticoid-induced osteoporosis and should be managed according to The American College of Rheumatology (ACR) guidelines.

Peptic Ulcer

Moderate:

Duralone

The methylPREDNISolone in Duralone has a moderate potential interaction with Peptic Ulcer.

Corticosteroids may cause peptic ulcer disease and gastrointestinal (GI) hemorrhage, usually when given in high dosages or for prolonged periods. However, even conventional dosages may aggravate symptoms in patients with a history of peptic ulcers. Delayed healing of ulcers has also been reported. Therapy with corticosteroids should be avoided or administered cautiously in patients with active or latent peptic ulcers or other risk factors for GI bleeding. Some clinicians recommend the use of prophylactic antacids or H2-antagonists between meals when large doses of corticosteroids are necessary.

Post MI Syndrome

Moderate:

Duralone

The methylPREDNISolone in Duralone has a moderate potential interaction with Post MI Syndrome.

The use of corticosteroids may be associated with left ventricular free-wall rupture in patients who have had a recent myocardial infarction. Pharmacologic dosages of corticosteroids should be administered with great caution in such patients.

Prader-Willi Syndrome

Major:

somapacitan

Somapacitan has a major potential interaction with Prader-Willi Syndrome.

The use of somapacitan is contraindicated in pediatric patients with Prader-Willi syndrome who are severely obese, have a history of upper airway obstruction or sleep apnea or have severe respiratory impairment due to risk of sudden death.

Prematurity/Underweight in Infancy

Major:

Duralone

The methylPREDNISolone in Duralone has a major potential interaction with Prematurity/Underweight in Infancy.

The use of certain parenteral formulations of dexamethasone, hydrocortisone, methylprednisolone, prednisolone and triamcinolone is considered by the drug manufacturers to be contraindicated in neonates, particularly premature infants and infants of low birth weight. Some formulations of these drugs contain benzyl alcohol which, when used in bacteriostatic saline intravascular flush and endotracheal tube lavage solutions, has been associated with fatalities and severe respiratory and metabolic complications in low-birth-weight premature infants. However, many experts feel that, in the absence of benzyl alcohol-free equivalents, the amount of the preservative present in these formulations should not necessarily preclude their use if they are clearly indicated. The American Academy of Pediatrics considers benzyl alcohol in low doses (such as when used as a preservative in some medications) to be safe for newborns. Continuous infusions of high dosages of medications containing benzyl alcohol may, however, cause toxicity and should be avoided if possible.

Psychosis

Moderate:

Duralone

The methylPREDNISolone in Duralone has a moderate potential interaction with Psychosis.

Corticosteroids may aggravate the symptoms of psychosis and emotional instability. Patients with these conditions should be monitored for increased or worsened symptoms during corticosteroid therapy.

Pulmonary Impairment

Major:

somapacitan

Somapacitan has a major potential interaction with Pulmonary Impairment.

Somapacitan is contraindicated in patients with acute critical illness after open-heart surgery, abdominal surgery or multiple accidental trauma, or those with acute respiratory failure because of the risk of increased mortality with use of pharmacologic doses of this drug.

Renal Dysfunction

Moderate:

Duralone

The methylPREDNISolone in Duralone has a moderate potential interaction with Renal Dysfunction.

Corticosteroids may cause hypernatremia, hypokalemia, fluid retention, and elevation in blood pressure. Large doses of any corticosteroid can demonstrate these effects, particularly if given for longer periods. Therapy with corticosteroids should be administered cautiously in patients with preexisting fluid retention, hypertension, congestive heart failure, and/or renal dysfunction. Dietary sodium restriction and potassium supplementation may be advisable.

Scoliosis

Moderate:

somapacitan

Somapacitan has a moderate potential interaction with Scoliosis.

Somapacitan increases growth rate, and progression of preexisting scoliosis can occur in patients who experience rapid growth. Monitor patients with a history of scoliosis for disease progression.

Seizures

Moderate:

Duralone

The methylPREDNISolone in Duralone has a moderate potential interaction with Seizures.

Corticosteroids can cause hypernatremia, hypokalemia, and fluid retention. These mineralocorticoid effects are most significant with fludrocortisone, followed by hydrocortisone and cortisone, then by prednisone and prednisolone. The remaining corticosteroids, betamethasone, dexamethasone, methylprednisolone, and triamcinolone, have little mineralocorticoid activities. However, large doses of any corticosteroid can demonstrate these effects, particularly if given for longer than brief periods. All corticosteroids also increase excretion of calcium and can cause hypocalcemia. Therapy with corticosteroids should be administered cautiously in patients with preexisting electrolyte disturbances. Caution is also advised when treating patients with seizure disorders, since electrolyte disturbances may trigger seizure activity.

Skin Cancer

Major:

somapacitan

Somapacitan has a major potential interaction with Skin Cancer.

Somapacitan is contraindicated in patients with active malignancies. There is an increased risk of neoplasm when using this drug. Monitor closely patients with preexisting tumors for progression or recurrence. There is an increased risk of a second neoplasm in childhood cancer survivors treated with somatropin, in particular meningiomas in patients treated with radiation to the head for their first neoplasm. Children with certain rare genetic causes of short stature have an increased risk of developing malignancies, so thoroughly consider the risks and benefits of starting somapacitan in these patients. If treatment is initiated, carefully monitor these patients for development of neoplasms. There is risk of malignant changes of preexisting nevi with somatropin treatment. Monitor patients on therapy carefully for increased growth or potential malignant changes of preexisting nevi. Advise patients/caregivers to report marked changes in behavior, onset of headaches, vision disturbances, and/or changes in the appearance of preexisting nevi.

Strongyloidiasis

Moderate:

Duralone

The methylPREDNISolone in Duralone has a moderate potential interaction with Strongyloidiasis.

Unlike most helminths, Strongyloides stercoralis has the ability to replicate in the human host. In patients with strongyloidiasis, the use of pharmacologic or immunosuppressive dosages of corticosteroids may result in Strongyloides hyperinfection and dissemination with widespread larval migration, often accompanied by severe enterocolitis and potentially fatal gram-negative septicemia. Therapy with corticosteroids should be administered with extreme caution, if at all, in these patients. For patients on corticosteroids who develop known or suspected Strongyloides infestation, withdrawal of corticosteroids or reduction of the dose of corticosteroids is recommended.

Systemic Sclerosis

Moderate:

Duralone

The methylPREDNISolone in Duralone has a moderate potential interaction with Systemic Sclerosis.

In patients with scleroderma, corticosteroids may precipitate renal crisis with malignant hypertension, possibly via steroid-induced increases in renin substrate and angiotensin II levels and decreases in vasodilator prostaglandin production. Renal failure may ensue. Therapy with corticosteroids should be administered cautiously in patients with scleroderma. In addition, they should be limited to short-term use.

Thrombotic/Thromboembolic Disorder

Moderate:

Duralone

The methylPREDNISolone in Duralone has a moderate potential interaction with Thrombotic/Thromboembolic Disorder.

Corticosteroids may increase blood coagulability and have rarely been associated with the development of intravascular thrombosis, thromboembolism, and thrombophlebitis. Therapy with corticosteroids should be administered cautiously in patients who have or may be predisposed to thrombotic or thromboembolic disorders.

Tuberculosis, Latent

Moderate:

Duralone

The methylPREDNISolone in Duralone has a moderate potential interaction with Tuberculosis, Latent.

In patients with latent tuberculosis or tuberculin reactivity, the use of pharmacologic dosages of corticosteroids may cause a reactivation of the disease. Close monitoring for signs and symptoms of tuberculosis is recommended if corticosteroid therapy is administered to patients with a history of tuberculosis or tuberculin reactivity. During prolonged corticosteroid therapy, tuberculosis chemoprophylaxis may be considered.

Ulcerative Colitis

Moderate:

Duralone

The methylPREDNISolone in Duralone has a moderate potential interaction with Ulcerative Colitis.

Corticosteroids may cause gastrointestinal perforation and hemorrhage, usually when given in high dosages or for prolonged periods. They may also mask symptoms of complications such as peritonitis or intraabdominal sepsis. Therapy with corticosteroids should be avoided or administered cautiously in patients with diverticulitis, nonspecific ulcerative colitis (if there is a probability of impending perforation, abscess, or other pyogenic infection), or recent intestinal anastomoses.

Underactive Thyroid

Moderate:

Duralone

The methylPREDNISolone in Duralone has a moderate potential interaction with Underactive Thyroid.

Corticosteroids may have enhanced effects in hypothyroidism due to decreased metabolism of these agents. Patients with hypothyroidism should be monitored more closely for excessive cortisol effects. Dosage adjustments may be required secondary to changes in their thyroid condition.

Moderate:

somapacitan

Somapacitan has a moderate potential interaction with Underactive Thyroid.

Undiagnosed or untreated hypothyroidism may prevent an optimal response to somapacitan treatment. In patients with growth hormone deficiency, central (secondary) hypothyroidism may first become evident or worsen during treatment with somatropin therapy. Therefore, patients should have periodic thyroid function tests and thyroid hormone replacement therapy should be initiated or appropriately adjusted when indicated.
