Кортеф (hydrocortisone) is a medication utilized in the management of a diverse range of conditions primarily falling into two domains: replacement therapy and anti-inflammatory/immunosuppressive treatment. It is considered the preferred choice for addressing states of adrenal gland insufficiency, which involves the replacement of hormones that are typically produced naturally by the body. This includes both primary and secondary adrenocortical insufficiency, as well as congenital adrenal hyperplasia.

In addition to its role in hormone replacement, the medication is also indicated for its effect on the immune system and its influence on inflammation. It is prescribed for the short-term or maintenance management of various rheumatic, allergic, and dermatologic disorders, such as systemic lupus erythematosus, bronchial asthma, and severe allergic reactions that have not responded adequately to conventional therapies. Furthermore, it is applied in the palliative management of certain blood cell disorders and neoplastic diseases (e.g., leukemias and lymphomas).

Healthcare providers may also use this medication to address symptoms associated with specific eye, respiratory, and gastrointestinal conditions, including ulcerative colitis and regional enteritis.

Кортеф (hydrocortisone) is a corticosteroid used to treat a wide range of conditions, primarily those involving inflammation, immune system disorders, or adrenal insufficiency. It works by replacing hydrocortisone in individuals with low levels, or by suppressing the immune system to reduce inflammation in other conditions.

Who Can Use Кортеф?

Prescription is typically made for treatment in the following areas:

• Endocrine Disorders: Primary or secondary adrenocortical insufficiency (e.g., Addison's disease), congenital adrenal hyperplasia.
• Rheumatic, Allergic, and Skin Conditions: Conditions such as rheumatoid arthritis, lupus, severe allergies, and various dermatologic diseases.
• Respiratory, Hematologic, and Gastrointestinal Conditions: Including bronchial asthma, certain blood cell disorders, and temporary treatment for conditions like ulcerative colitis.

Who Should NOT Use Кортеф?

Кортеф is contraindicated (should not be used) in patients with a systemic fungal infection that is not being managed with antifungal medication, and in individuals with a known hypersensitivity or allergy to hydrocortisone or any other ingredient in the formulation.

Caution must be exercised, and a healthcare provider should be informed of any co-existing medical conditions, including:

Condition	Reason for Caution
Active or Latent Infections	May reduce immune response and mask symptoms
Diabetes, Glaucoma, Osteoporosis	May worsen these pre-existing conditions
Mental Health Conditions	Possible mood or behavioral changes
Recent Live or Live-Attenuated Vaccines	Risk of diminished vaccine efficacy

Use in pregnancy and during breastfeeding requires careful consideration of the potential benefits versus the risks.

Interactions with other medicines and products

Hydrocortisone (Кортеф) has documented interactions with several classes of medicinal products, which may necessitate dosage adjustments or close monitoring during co-administration.

Interacting Product Category	Mechanism and Interaction Result
Enzyme Inducers (e.g., rifampin, phenytoin, phenobarbital)	These drugs can increase the metabolic clearance of hydrocortisone, which leads to lower plasma levels and may reduce the corticosteroid’s therapeutic effect; a dosage increase of hydrocortisone may be required.
CYP3A4 Inhibitors (e.g., ketoconazole)	These agents can decrease the clearance of hydrocortisone, potentially resulting in increased plasma concentrations and an elevated risk of systemic corticosteroid side effects; a dosage reduction of hydrocortisone may be necessary.
Vaccines (Live or Live, Attenuated)	Administration is contraindicated in patients receiving immunosuppressive doses of hydrocortisone due to the risk of infection. The response to killed or inactivated vaccines may also be diminished.
Nonsteroidal Anti-inflammatory Drugs (NSAIDs)	Concomitant use increases the risk of serious gastrointestinal side effects, including peptic ulceration and hemorrhage.
Anticoagulants (Coumarin derivatives)	Corticosteroids can increase or decrease the effects of these blood-thinners, and patients require close monitoring of their clotting status.
Antidiabetics (e.g., insulin, oral hypoglycemic agents)	Corticosteroids may elevate blood glucose, which may increase the patient’s requirement for antidiabetic medication.

Additionally, Mifepristone is not recommended for use with hydrocortisone as it may block the intended therapeutic effect of the corticosteroid. If any interacting medicine is started or stopped, adjustment of the Cortef dosage may be needed, as per regulatory guidance.

Cortef (hydrocortisone) is a synthetic glucocorticoid that acts by engaging essential regulatory pathways within the cell to modulate signaling within targeted pathways. Its mechanism operates across two primary domains: genomic modulation and pathway suppression, influencing signaling dynamics associated with physiological responses. The overall action leads to changes in gene expression that result in systemic physiological effects.

Glucocorticoid Receptor Activation and Gene Modulation

This mechanism initiates when the drug binds to the cytosolic Glucocorticoid Receptor (GR). The activated drug-receptor complex translocates to the cell nucleus, where it functions as a transcription factor, modulating the expression of specific genes. This influences the creation of new proteins, which initiates the biological cascade leading to systemic consequences.

Suppression of Inflammatory and Immune Pathways

This effect results from transrepression, where the activated complex physically interferes with key transcription factors, including NF-kB and AP-1. By blocking these regulators, Cortef suppresses the downstream production of pro-inflammatory mediators like cytokines and prostaglandins, modifying the balance of pro- and anti-inflammatory mediators and influencing the dynamics of immune and inflammatory responses.

How to use Cortef (Hydrocortisone Tablets) — Administration Guidelines

Cortef is an oral medication (tablets) for systemic use that must be administered according to an individualized dosage regimen set by a healthcare provider. The core principle of administration is to use the lowest possible dose that can effectively control the treated condition. Dosage requirements are variable and must be adjusted based on the patient's specific needs and response.

Procedural Steps

Administration Aspect	Guideline
Route & Preparation	Oral (tablets). No preparation (e.g., dilution or shaking) is required.
Dosing Adjustment	After a favorable response, the initial dosage should be determined by gradual, small decrements until the lowest effective maintenance dosage is reached.
Discontinuation	Following long-term therapy, the drug must be withdrawn gradually, not abruptly, to minimize the risk of secondary adrenocortical insufficiency.
Handling Stressful Situations	In patients undergoing unusual stress (e.g., infection, surgery, or trauma), an increased dosage of rapidly acting corticosteroids is indicated before, during, and after the stressful situation.
Pediatric Considerations	For cases of congenital adrenal hyperplasia in infants, mineralocorticoid supplementation is of particular importance and should be administered concurrently.

Drug-induced secondary adrenocortical insufficiency may persist for months after the medication is discontinued; therefore, hormone therapy should be reinstituted if the patient experiences any stress during that period. Cortef is administered orally, with the tablet taken whole. While the tablets are available in 5 mg, 10 mg, and 20 mg strengths, the individual dose and frequency must always be determined by the treating physician.

Research evidence / Overview of Studies for Кортеф (Hydrocortisone)

Evidence for Hormone Replacement in Adrenal Insufficiency

Research for this primary indication focuses on hydrocortisone's use as a strategy for replacing naturally produced cortisol, which the adrenal glands fail to produce adequately in patients with Primary or Secondary Adrenal Insufficiency. Studies conducted during periods of temporary physiological imbalance have explored how symptoms change over time when hydrocortisone is administered. These studies were designed to monitor patient-reported outcomes describing perceived discomfort, such as Health-Related Quality of Life (HRQoL) scores, and key metabolic markers like blood pressure and body weight.

The findings describe patterns observed in these studies, showing a relationship between daily dosing regimens and the concentrations of cortisol measured in the blood over a 24-hour period. This evidence contributes to the broader evidence landscape, where glucocorticoid replacement is an established medical strategy.

Evidence for Managing Congenital Adrenal Hyperplasia (CAH)

Hydrocortisone was studied for its use in patients with Congenital Adrenal Hyperplasia (CAH), a condition marked by functional limitations and hormonal imbalance. The research primarily examined biochemical markers of disease, such as levels of 17-hydroxyprogesterone (17OHP), and monitored physical development outcomes like growth and height in child and adolescent populations. Research describes that hydrocortisone administration was observed in some studies to lead to changes in the levels of the monitored hormonal precursors.

Evidence for Anti-Inflammatory Use in Critical Care

The use of hydrocortisone for its anti-inflammatory effects was evaluated in large, multinational Randomized Controlled Trials (RCTs) involving critically ill adult patients experiencing septic shock and requiring support for low blood pressure. The main outcomes monitored were all-cause mortality rates over defined time intervals (typically 28 and 90 days), as well as the time required for shock reversal. Findings were mixed across some of the largest trials regarding the most critical outcome, all-cause mortality. The overall certainty remains low for certain outcomes, particularly when hydrocortisone is used alone, as some trials examined it in combination with other medications.

What is Still Uncertain About Hydrocortisone Research

Research is ongoing to determine if it is possible to perfectly mimic the body's natural cortisol pattern across all individuals using oral tablets. For many anti-inflammatory uses in rheumatic diseases, the evidence is limited to the general class of glucocorticoids, rather than studies that only examined oral hydrocortisone. This means that research provides context, but it does not determine whether an individual will respond similarly when compared to findings for other steroid medications.
