Solu-Cortef lyophilizate, 100 mg vials+2 ml

How to take, the dosage

The drug may be administered as an IV or IM injection or as an IV infusion, but in acute conditions, it is preferable to start treatment with an IV injection. At the end of the acute period, either parenteral dosage forms of the drug with longer duration of action or oral forms of the drug are prescribed. Treatment with the drug begins with an IV for 30 s (e.g., 100 mg) and up to 10 minutes (e.g., 500 mg or more). High doses of GCS should be administered only until the patient’s condition has stabilized, but for no longer than 48-72 hours. The initial dose of the drug is 100-500 mg or more, depending on the severity of the patient’s condition. The dose is administered repeatedly every 2, 4 or 6 hours depending on the response of the patient’s body and the clinical picture of the disease. Lower doses (but not less than 25 mg/day) should be given in children, but when choosing the dose, the severity of the condition and the patient’s response to therapy should be primarily considered, rather than age and body weight.

Preparation of solutions

Parenteral preparations should be checked visually for color changes or particulates. Only a clear solution should be used.

Vial

For intravenous or intravenous injection, prepare the solution by adding to the vial (observing the rules of antisepsis) not more than 2 ml of water for injection or aqueous sodium chloride solution for injection with a bacteriostatic additive. For IV infusion, the solution is first prepared by adding not more than 2 ml of water for injection to the vial, then this solution can be added to 100-1000 ml of 5% aqueous dextrose solution (or 0.9% sodium chloride solution, or 5% dextrose solution in 0.9% sodium chloride solution if the patient does not need sodium restriction).

The ACT-O-VIAL Dual Cap Vial

1. Press the plastic activator to allow the solvent to pour into the lower container.

2. gently rock the vial until the lyophilizate dissolves.

3. Remove the plastic disc that covers the center of the cap.

4. cauterize the surface of the tube with an antiseptic.

5. Prick the center of the tube with a needle so that the tip of the needle is visible. Invert the vial and draw out the desired amount of solution with the syringe.

For intravenous or intramural injections no further dilution is necessary. For intravenous infusion, the solution is first prepared as described above, then the resulting solution is added to 100-1000 ml of 5% aqueous dextrose solution (or 0.9% sodium chloride solution, or 5% dextrose solution in 0.9% sodium chloride solution if the patient does not need sodium restriction). If a small volume of fluid is desired, you can add 100-3000 mg of hydrocortisone (as hydrocortisone sodium succinate) to 50 ml of the above solutions. The resulting solutions are stable for 4 h and can be administered by IV directly or via a second IV.

If the drug solutions are prepared as above, pH = 7-8 and osmolarity = 0.36 osmol (osmolarity of 0.9% sodium chloride solution 0.28 osmol).

Interaction

Hepatic microsomal enzyme inducers such as phenobarbital, phenytoin, and rifampicin may increase clearance of GCS, which may require increasing the dose of the drug to obtain the desired effect.

Drugs such as troleandomycin and ketoconazole can inhibit the metabolism of GCS and decrease its clearance. If this occurs, the dose of GKS should be reduced to avoid overdose events.

The GCS can increase clearance of acetylsalicylic acid taken in high doses for a long period, which can lead to decreased serum concentrations of salicylates or increase the risk of toxicity of salicylates during withdrawal of GCS. In patients with hypoprothrombinemia, acetylsalicylic acid in combination with GCS should be prescribed with caution.

The effect of GCS on the effect of indirect anticoagulants is variable. Both enhancement and reduction of the effect of anticoagulants taken concomitantly with hydrocortisone have been reported. Continuous determination of blood clotting parameters is necessary to maintain the desired effect of anticoagulant.

Special Instructions

Hypernatremia may occur if high doses of hydrocortisone are administered for a period longer than 48-72 hours. In this case, it is recommended to replace Solu-Cortef with another GKS, such as methylprednisolone sodium succinate, which causes little or no retention of sodium in the body.

Patients who may be stressed by GCS therapy are indicated to increase the dose of the drug before, during and after the stressful situation. These patients should be closely monitored by a physician because of the possibility of adrenal insufficiency.

With GCS therapy, some infections may occur in a milder form, and new infections may also develop. With GCS use, resistance to infections may decrease and the ability of the body to localize the infectious process may decrease. The development of infections caused by various pathogenic organisms such as viruses, bacteria, fungi, protozoa or helminths that localize in different systems of the human body can be associated with the use of GCS, either as monotherapy or in combination with other immunosuppressants affecting cellular immunity, humoral immunity or neutrophil function. These infections may be mild, but in some cases a severe course and even death are possible. The higher doses of GCS are used, the greater the likelihood of infectious complications.

The use of hydrocortisone in active tuberculosis should be limited to cases of fulminant and disseminated tuberculosis, when GCS is used to treat the disease in combination with appropriate anti-tuberculosis chemotherapy. If GKS are administered to patients with latent tuberculosis or with positive tuberculin tests, the treatment should be performed under close medical supervision, since reactivation of the disease is possible. During long-term therapy with the drug, such patients should receive appropriate prophylactic treatment.

Patients treated with GCS at doses that are immunosuppressive are contraindicated in live or live-weakened vaccines, but killed or inactivated vaccines may be given, but the response to administration of these vaccines may be reduced. Patients treated with GCS in doses that are not immunosuppressive may be immunized for appropriate indications.

Hydrocortisone administration may lead to increased blood pressure, water and salt retention in the body, and increased potassium excretion. Restriction of salt intake with food and additional potassium supplementation may be necessary. All GCSs increase calcium excretion from the body. Since patients receiving parenteral GCS therapy may in rare cases have anaphylactoid reactions (e.g., bronchospasm), appropriate preventive measures should be taken before the drug administration, especially if this patient has a history of allergic reactions to any medications.

Long daily therapy with GCS in children may lead to growth retardation, so this dosing regimen should be used in children only if there is a strong indication. Acute myopathy most commonly develops with high doses of GCS in patients with impaired neuromuscular transmission (e.g., myasthenia gravis), or in patients simultaneously treated with peripheral myorelaxants (e.g., pancuronium). Such acute myopathy is generalized, can affect the muscles of the eye and respiratory system, lead to the development of traparesis. Creatine phosphokinase may increase. At the same time, improvement or recovery after withdrawal of GCS may occur only after many weeks or even after several years.

Impact on driving and operating machinery

Because of the possibility of side effects on the nervous system (e.g., seizures) and the visual system, persons taking Solu-Cortef should be careful when driving vehicles and engaging in other potentially dangerous activities requiring increased concentration and quick psychomotor reactions.

Features

After intravenous injection, the C_max of hydrocortisone in plasma is reached after approximately 30-60 minutes.

Approximately 40-90% of hydrocortisone is bound to plasma proteins. Most of the hydrocortisone binds to one of the globulins (transcortin) and only a small amount binds to albumin. The free unbound fraction of the hormone determines its biological activity, and the bound fraction serves as a reserve.

The metabolism of hydrocortisone occurs mainly in the liver. Within 24 hours, 22-30% of the injected hydrocortisone is excreted in the urine. The drug is almost completely eliminated from the body within 12 hours, so in order to maintain high concentrations of hydrocortisone in the blood it is necessary to administer it in m/m or intravenously every 4-6 hours.

Contraindications

The drug is not indicated in patients with acute and subacute myocardial infarction because its use in these patients may cause spreading of necrosis, delay formation of scar tissue and, therefore, rupture of the heart muscle;

The product, which is available in ACT-O-VIAL dual-volume bottles, is not recommended for use in infants because the solvent contains benzyl alcohol.

The product should be used with caution in the following cases:

• in eye lesions caused by herpes simplex virus, as this may lead to corneal perforation;
• in ulcerative colitis if there is a risk of perforation, abscess or other purulent infection, as well as in diverticulitis, fresh intestinal anastomoses, active or latent peptic ulcer, renal failure, arterial hypertension, osteoporosis, myasthenia gravis.
