Zycortal® (Dechra Veterinary Products) is indicated for replacement therapy for mineralocorticoid deficiency in dogs with primary hypoadrenocorticism. Zycortal contains desoxycortone pivalate (DOCP) – an aldosterone analogue with purely mineralocorticoid effect. Zycortal is available as a prolonged-release suspension for subcutaneous injection and the dosing interval is approximately 25 days. The exact dose to be given and the interval between treatments depend on the dog’s clinical response as well as sodium and potassium levels. A glucocorticoid (. prednisolone) is also needed daily to replace the missing cortisol. To obtain a Monitoring and Dose Adjustment Flowchart, or for further advice, contact Dechra by e-mailing technical@.
Cushing's syndrome is the result of excessive corticosteroids in the body. The main cause is overproduction of adrenocorticotropin hormone (ACTH) in the pituitary gland. ACTH causes the adrenal glands to produce corticosteroids, so too much of ACTH means too much of corticosteroids. Another main cause is taking long-term external steroids like prednisone (sometimes used in some chronic diseases). In addition, certain lung cancers and other tumors outside the pituitary gland may produce corticotropins. Other causes include benign or cancerous tumors on the adrenal glands. Rarely, Cushing syndrome can be an inherited endocrine disorder.
This schedule is designed to ensure adequate therapy during acute episodes, while minimizing the risk of overdosage in chronic cases.
In cerebral edema, Dexamethasone Sodium Phosphate injection, USP is generally administered initially in a dosage of 10 mg intravenously followed by 4 mg every six hours intramuscularly until the symptoms of cerebral edema subside. Response is usually noted within 12 to 24 hours and dosage may be reduced after two to four days and gradually discontinued over a period of five to seven days. For palliative management of patients with recurrent or inoperable brain tumors, maintenance therapy with either Dexamethasone Sodium Phosphate injection, USP or dexamethasone tablets in a dosage of 2 mg two or three times daily may be effective.
