Both methylprednisolone acetate (Depo-Medrol) and methylprednisolone succinate (Solu-Medrol) are approved for intramuscular injection. [23] [22] Depo-Medrol is additionally approved for intralesional, intra-articular, and soft tissue injections. Depo-Medrol is available as sterile aqueous solution in 20 mg/mL, 40 mg/mL, or 80 mg/mL strengths. [23]
Methylprednisolone acetate, sold under the brand names Depo-Medrol among others, is a synthetic glucocorticoid corticosteroid and a corticosteroid ester—specifically the C21 acetate ester of methylprednisolone—which is used in clinical and veterinary medicine.
The elimination half-life of progesterone with this formulation is about 8 days. [36] A single 200 mg intramuscular injection maintains progesterone levels of more than 10 ng/mL for 5 to 7 days. [36] ProSphere is well tolerated in terms of injection site reactions. [185]
Vial of Depo-Testosterone, a depot injection of testosterone. A depot injection, also known as a long-acting injectable (LAI), is a term for an injection formulation of a medication which releases slowly over time to permit less frequent administration of a medication.
The elimination half-life of MPA via oral administration has been reported as both 11.6 to 16.6 hours [6] and 33 hours, [4] whereas the elimination half-lives with intramuscular and subcutaneous injection of microcrystalline MPA in aqueous suspension are 50 and 40 days, respectively.
Prednisolone has a relatively short half-life, ranging 2–4 hours. It also has a large therapeutic window, considering the dosage required to produce a therapeutic effect is a few times higher than what the body naturally produces. [14] Prednisolone is 70–90% plasma protein bound, it binds to proteins such as albumin. [14]
CICs are administered by intramuscular injection into the deltoid, gluteus maximus, or anterior thigh. [1] They are ideally administered every 28 to 30 days, though they have been demonstrated to be effective up to 33 days. [1] Some CICs have been said to be used by transgender women as a means of feminizing hormone therapy as well. [12]
Intramuscular injections began to be used for administration of vaccines for diphtheria in 1923, whooping cough in 1926, and tetanus in 1927. [30] By the 1970s, researchers and instructors began forming guidance on injection site and technique to reduce the risk of injection complications and side effects such as pain. [ 8 ]
