H.P. Acthar Gel (repository corticotropin injection) is referred as single therapy for treating infantile spasms in infants and children with less than 2 years of age. It is indicated for treating acute exacerbations of multiple sclerosis in adults too. Restrained clinical attempts have proved gel to be effective in speeding the settlement of intense exacerbations of several scleroses. However, there is no clue that it disturbs ultimate results or natural history of the disease.
The drug also is used in diagnosing adrenal gland function. The drug is used to treat certain conditions which are formed due to allergies; breathing, blood, or endocrine problems; arthritis; skin or eye problems; bowel inflammation; multiple sclerosis; or certain cancers. The drug is also useful in various instances as determined by your doctor. HP Acthar gel is a hormone. It works effectively by appealing body to create more adrenocortical hormones for e.g., corticosteroids, glucocorticoids.
H.P. Acthar Gel is a deeply purified sterile arrangement of adrenocorticotropic hormone in 16% gelatin to give a long lasting release followed by intramuscular or subcutaneous injection. It also holds 0.5% phenol, not more than 0.1% cysteine (added), sodium hydroxide and/or acetic acid to adjust pH and water for injection.

Infantile spasms – The solution is indicated as monotherapy for the treatment of infantile spasms in infants and children less than 2 years of their age.
Multiple Sclerosis – The formula is used for treating acute exacerbations of multiple sclerosis in adults. Controlled clinical trials have shown the solution to be resultant in speeding the resolution of keen exacerbations of several sclerosis. However, there is no proof that it affects the ultimate outcome or natural history of any disease.
In the treating infantile spasms, it must be administered intramuscularly. The preferred procedure is a daily dose of 150 U/m² (divided into twice daily intramuscular injections of 75 U/m²) intakes over a 2-week of period. The Dosage with should be gradually tapered over a 2-week period to relieve adrenal insufficiently. Further given are some tapering schedule like: 30 U/m² in the morning for 3 days; 15 U/m² in the morning for 3 days; 10 U/m² in the morning for 3 days; and 10 U/m² every other morning for 6-days.
The drug is commonly dosed based on body surface area (BSA). Thus, for calculation of body surface area, use the following formula: BSA (m²) =√ weight (kg) x height (cm) / 3600.
High or over doses can be combined with an array of hidden deliberate conflicting effects. It is unexpected that a single high dose, or even several large doses, has the potential for deliberate adverse effects compared to other standard dose. There have been no records of death or keen overdose symptoms with intake of this drug in clinical studies or in the published informative literature. The intramuscular way of administrating the formula makes it unlikely which a reckless intense overdose may occur. The typical daily dose of the drug to treat an infant suffering from a BSA of 0.4 m² would be 60 U/day. Using the 1-cc syringe supplied with the gel, the maximum amount which is to be injected is 80 U/injection, which is a well-tolerated single dose with no harm and cause.
