Cushing's disease is a rare subtype of Cushing’s syndrome caused by a benign pituitary tumor that overproduces adrenocorticotropic hormone (ACTH), causing excessive cortisol production by the adrenal glands. This condition disrupts normal cortisol rhythms and can cause serious complications and early death if left untreated.
Surgery is often the primary treatment for Cushing's disease because it directly addresses the root cause of the condition. However, medications can also be an important part of treatment for Cushing’s disease.
Medication is used for patients with persistent or recurrent disease after surgery, for those who are not candidates for surgery, or in cases where rapid cortisol control is needed due to severe hypercortisolism or life-threatening complications.
In this article we’ll cover the medications available for treating Cushing's Disease including a discussion of their uses, how they work, and what patients can expect from medication use as they heal from Cushing’s disease.

Understanding the Role of Cortisol in Cushing’s Disease
Excessive cortisol levels, or cortisolemia, is the cause of the disease process seen in Cushing’s.
What is Cortisol?
Cortisol, a glucocorticoid hormone, is often called a stress hormone because it is foundational to our stress response. However, cortisol has many roles in normal human physiology.
Cortisol:
- Regulates metabolism (promoting gluconeogenesis and reducing glucose uptake)
- Supports the stress response (mobilizing energy and increasing alertness through neuroendocrine signaling pathways)
- Increases blood pressure (enhancing vasoconstriction and increasing blood volume)
- Supports fetal lung and nervous system development
- Maintains bone health by balancing bone formation and resorption
How Cushing’s Disease Affects Cortisol Production
Cushing’s syndrome is the general condition that refers to the condition of hypercortisolism, while Cushing’s disease specifically refers to hypercortisolism due to an ACTH-secreting pituitary tumor.
The pathophysiology of Cushing's syndrome involves prolonged exposure to high levels of cortisol.
In Cushing’s disease, the pituitary adenoma secretes excessive ACTH which stimulates the adrenal cortex to over-produce cortisol.
Elevated cortisol leads to increased gluconeogenesis, protein catabolism, insulin resistance, and immune suppression, manifesting in various symptoms like weight gain, muscle weakness, osteoporosis, hypertension, and susceptibility to infections.
Why Managing Cortisol is Critical
Chronic excessive cortisol exposure has disastrous long-term health consequences. The mortality rate of Cushing disease is estimated to be 10-11%. Successful recovery from Cushing disease may still leave the patient with other chronic health conditions such as diabetes, cardiovascular disease, osteoporosis, or chronic mental health conditions.
Common symptoms of Cushing’s disease include central obesity, with fat accumulation in the abdomen, face ("moon face"), and upper back ("buffalo hump").
Skin changes, such as thinning, slow wound healing, and purple stretch marks, also occur due to disrupted collagen production. Patients may experience acne and altered hair growth, especially women and prepubertal children.
Muscle weakness in the limbs creates a contrast between a large abdomen and thin extremities.
Elevated cortisol can also cause mood disturbances including depression, anxiety, and cognitive impairment, as well as high blood pressure due to fluid retention.
Metabolic issues like insulin resistance, hyperglycemia, and hyperlipidemia are common, along with bone health problems such as osteoporosis, resulting in fragile bones and back pain.
Reproductive health may also be affected, with women facing menstrual irregularities and men experiencing decreased libido or erectile dysfunction.
Other symptoms include increased thirst and urination, headaches, visual disturbances, and decreased immunity, which can mimic conditions like diabetes or cardiovascular disease.
Types of Medications for Cushing’s Disease
Medical management of Cushing's Disease requires careful selection and monitoring of therapies to balance efficacy and side effects, considering patient-specific factors and disease severity.
Here we’ll discuss the different classes of medications used including their mechanism of action, clinical indications, potential side effects and monitoring requirements.
Adrenal Steroidogenesis Inhibitors
Ketoconazole, metyrapone, mitotane, etomidate, and osilodrostat are steroidogenesis inhibitors that block adrenal enzymes to reduce cortisol production.
Ketoconazole is effective but can cause liver toxicity and male hypogonadism, requiring regular liver function monitoring. It may also lead to gastrointestinal issues.
Metyrapone and osilodrostat provide rapid cortisol control but can cause adrenal insufficiency, androgenic effects, hypertension, gastrointestinal upset, and hypokalemia.
Mitotane is less commonly used due to slower action and neurological side effects. It can cause gastrointestinal disturbances, CNS effects, and teratogenicity. Mitotane also accelerates the metabolism of other steroids, complicating glucocorticoid replacement.
Etomidate is used for rapid cortisol reduction in severe hypercortisolism cases, typically in hospitalized patients.
Monitoring for all steroidogenesis inhibitors includes watching for symptoms of adrenal insufficiency (fatigue, nausea, vomiting, hypotension, electrolyte imbalances), regular checks of blood glucose, lipid levels, and other metabolic parameters, and monitoring blood pressure, especially with metyrapone, due to hypertension risk.
Pituitary-Directed Treatments
The primary pituitary-directed treatments for Cushing's disease (CD) are cabergoline and pasireotide, which both inhibit ACTH production in pituitary corticotroph tumors to lower cortisol levels.
Pasireotide targets somatostatin receptors, reducing cortisol and tumor size but often causes hyperglycemia, requiring careful management. Common side effects include gastrointestinal issues, hyperglycemia, gallstones, and elevated liver function tests, necessitating monitoring for glucose intolerance and metabolic disturbances.
Cabergoline, a dopamine agonist targeting D2 receptors, moderately lowers cortisol and tumor size but may cause impulse control problems and potential cardiac effects. Side effects include nausea, dizziness, and asthenia, with some concerns about long-term use leading to heart valve disease, though evidence is not definitive.
Glucocorticoid Receptor Antagonist
Mifepristone blocks cortisol effects, improving hyperglycemia and weight gain without reducing cortisol levels.
Mifepristone can cause symptoms of cortisol insufficiency, hypokalemia, hypertension, and endometrial thickening. Monitoring response is based on clinical symptoms rather than biochemical markers due to the nature of receptor blockade.
Monitoring for adrenal insufficiency is complex, and it should only be used by experienced clinicians due to its side effects and lack of biochemical markers to monitor efficacy.
Combination Therapy
Combination therapy is often used when monotherapy is insufficient. Common combinations include ketoconazole with metyrapone, or ketoconazole with cabergoline, to maximize cortisol suppression while potentially minimizing side effects. More aggressive combinations are used for severe hypercortisolism.
General Practice for Medication Selection and Monitoring
Clinicians keep the following themes in mind when selecting and monitoring an appropriate medication regimen:
Determining When to Use Medications
Medications may be used in the following situations:
Second-Line Therapy: medications are used when surgery is not possible, has failed, or when rapid cortisol control is needed. This applies to ACTH-dependent CS patients with noncurative or inoperable conditions, guided by patient preferences, CS cause, and urgency.
Primary Treatment for Ectopic ACTH Syndrome: if the tumor can't be localized, resected, or in cases of metastasis, use steroidogenesis inhibitors or glucocorticoid receptor antagonists.
Adjunctive Treatment: medications may lower cortisol in adrenocortical carcinoma or supplement radiation therapy.
Emergency Situations: for life-threatening hypercortisolism (e.g., severe infections, cardiovascular issues, psychosis), use steroidogenesis inhibitors or glucocorticoid receptor antagonists immediately to reduce cortisol levels.
Selection Criteria for Medication
Factors such as disease severity, need for rapid cortisol reduction, tumor presence, comorbidities (e.g., diabetes, hypertension), patient preferences, and potential side effects influence the choice of medication.
Specific drugs may be preferred based on patient characteristics, such as gender or pregnancy plans.
Overview of Medication Monitoring and Adjustments
Regular monitoring of cortisol levels, symptoms, and comorbidities is essential. Adjustments are made based on efficacy and side effects. Annual imaging is recommended to monitor tumor growth, particularly with long-term use of steroidogenesis inhibitors or mifepristone.
Preoperative and Long-term Use
Medication may be used preoperatively to control severe hypercortisolism or when surgery is delayed. Long-term use is generally for patients with persistent disease post-surgery or those not eligible for surgery.
Combination therapy may be necessary for chronic management.
What to Expect During Treatment
Patients with Cushing's syndrome typically begin to see a reduction in cortisol levels soon after starting medication, often within days to a few weeks. This is particularly true for steroidogenesis inhibitors, which have a rapid onset and high efficacy in reducing cortisol.
Regular monitoring of cortisol levels is essential to gauge the initial response and adjust the dosage accordingly.
Long-Term Management
Patients may need long-term, sometimes indefinite, medication use if surgery is not an option or was not fully curative. Management involves adjusting drug types and dosages to control cortisol and minimize side effects, with regular follow-ups for optimization.
Ketoconazole, metyrapone, and mitotane are used to inhibit adrenal steroidogenesis, reducing cortisol levels and managing Cushing’s Disease symptoms. However, efficacy can vary, and treatment escape is common.
Regular monitoring of cortisol, liver function (especially with ketoconazole due to hepatotoxicity), and blood levels is essential.
Mitotane requires monitoring for neurological side effects and adrenal insufficiency. Blood pressure, electrolytes (potassium), and glucose levels should be checked due to risks like hypokalemia and hypertension.
Mifepristone requires monitoring clinical symptoms and metabolic parameters (blood glucose, weight, blood pressure) to assess treatment response. Vigilance for adrenal insufficiency symptoms, such as weakness and fatigue, is crucial. Periodic imaging may be needed to monitor for potential tumor growth, particularly in the pituitary.
Cabergoline and pasireotide require regular monitoring of cortisol and ACTH levels. Cabergoline needs blood pressure and heart function checks due to risks of hypotension and cardiac issues. Pasireotide monitoring includes blood glucose, liver function, and thyroid function due to risks of hyperglycemia, liver enzyme elevation, and hypothyroidism.
Regular imaging may be necessary to track tumor size with long-term use of these medications.
Impact on Quality of Life
Medications for Cushing's Disease can greatly enhance quality of life by alleviating symptoms like fatigue, weight gain, high blood pressure, and mood disturbances. Drugs such as ketoconazole, metyrapone, mitotane, mifepristone, cabergoline, and pasireotide reduce cortisol production or its effects, leading to symptom relief.
This can result in increased energy levels, improved weight management, better blood pressure control, and enhanced mood and cognitive function. Effective treatment can improve both physical and mental health, significantly boosting overall well-being.
Regular monitoring and individualized therapy adjustments are crucial to maintaining these benefits and minimizing side effects.
When to Consult Your Doctor
Patients in recovery from Cushing’s disease may have questions regarding the efficacy of their treatments. Patients should always feel comfortable reaching out to their doctor with questions.
Signs That Medications Are Working
Effective treatment for Cushing's disease can be indicated by a noticeable reduction in symptoms such as fatigue, weight gain, high blood pressure, and mood disturbances. Additionally, laboratory tests showing normalized cortisol levels are a key marker of treatment success.
When to Report Side Effects
Some side effects may require immediate medical attention including severe headaches, significant changes in blood pressure, muscle weakness, unusual fatigue, hypokalemia (low potassium levels), jaundice (which may be due to liver damage from ketoconazole), or signs of adrenal insufficiency like dizziness and fainting.
It's important to promptly report these symptoms to a healthcare provider.
Adjusting Treatment Plans
Regular consultations with healthcare providers are crucial to monitor the effectiveness of the treatment and make necessary adjustments. This may involve altering dosages or switching medications to better manage symptoms, minimize side effects, and ensure optimal control of cortisol levels.
Alternative and Complementary Treatments
Treatment plans for Cushing’s disease may include the following:
Surgical Options
Surgery is often the first-line treatment for Cushing's disease, aiming to remove the pituitary tumor responsible for excess cortisol production. Transsphenoidal resection of the ACTH-secreting tumor can effectively normalize cortisol levels and alleviate symptoms.
Successful surgery, especially when performed by experienced surgeons, offers the best chance for long-term remission.
It is typically recommended after confirming the diagnosis and tumor localization via imaging, like MRI. The primary goals are to restore normal cortisol levels, improve symptoms, and reduce the risk of severe complications such as cardiovascular disease and diabetes.
Radiation Therapy
Radiation therapy (RT), including external-beam radiation and stereotactic radiosurgery (SRS), is used when surgery is insufficient or tumors are aggressive.
RT can achieve biochemical remission and control tumor growth but often leads to hypopituitarism, requiring lifelong monitoring for tumor recurrence and hormone deficiencies.
Lifestyle Modifications
Diet and lifestyle are foundational for recovery, with a focus on a healthy diet, regular exercise, good sleep, and stress management to support overall well-being and HPA axis function.
A balanced diet plays a crucial role in managing weight, blood sugar, and bone health, while regular exercise improves cardiovascular health, muscle strength, and mood.
Stress management is essential, as reducing stress helps prevent cortisol fluctuations and aids in recovery.
Ongoing medical monitoring is important for the early detection and management of complications such as hypertension, diabetes, osteoporosis, and psychological issues. Regular follow-ups are vital to ensure prompt treatment of emerging problems, supporting long-term health and quality of life.
