Myochrysine Injection Drug Description
Myochrysine Injection is the brand name of a medication that is used to treat rheumatoid arthritis (RA). It is a disease-modifying anti-rheumatic drug (DMARD) formulation prescribed for patients who cannot use or have not responded to other medications for the treatment of arthritis. Myochrysine Injection is often indicated as a part of a comprehensive treatment plan for patients suffering from RA, including non-drug treatments like physical therapy, rest etc. The prime ingredient in Myochrysine Injection is gold sodium thiomalate. The preparation is a mixture of monosodium and disodium salts of gold thiomalic acid. It is often referred to as gold shots, gold injections or injectible gold. Although gold sodium thiomalate is not a genuine pain reliever, it is effective in relieving morning stiffness in patients suffering from RA. It can also alleviate swelling or pain in the joints and improve grip strength. The injection is applied by the intramuscular route, usually in the buttocks i.e. gluteal muscles. Myochrysine Injection is an aqueous sterile solution containing 50mg / 25mg / 10mg of gold sodium thiomalate per ml. It also contains benzyl alcohol 0.5% as a preservative. The injection is available in boxes containing five ampoules each. In Canada, Myochrysine Injection is presented by Sanofi-Aventis.
Conditions Treated by Myochrysine Injection
Myochrysine Injection is prescribed in the treatment of both juvenile and adult RA for partial or complete remission. The best benefits of this medication can be obtained when used in the early stages of RA. In advanced stages, the medication may be beneficial is preventing further degeneration of the affected joints but cannot reverse the damage already caused. It is usually prescribed when the patient continues to show further damage despite being treated with other anti-inflammatory drugs or salicylates. Myochrysine Injection can also benefit patients suffering from Felty’s syndrome or psoriatic arthritis.
Myochrysine Injection Dosage Information
a.) Typical dosage recommendations
Like all other prescription drugs, typical dosage of Myochrysine Injection depends on individual condition, age, body weight, tolerance level and other medical conditions of the patient. The usual adult dose is 10mg IM (intra-muscular) once a week for the first week, 25mg once a week during the second week followed by 25 to 50mg of weekly injections for the next twenty weeks or till toxicity sets in. After this, patients with good or moderate tolerance level and improvement can be administered a maintenance dose of 50mg IM over a period of two to four weeks to be continued indefinitely. The usual paediatric dose of Myochrysine Injection is 10mg IM once weekly for the first week. This is followed by a maintenance dose of 1mg per kg of body weight per week. Under no circumstances should the dosage be more than 50mg/dose. To get the best benefit from Myochrysine Injection, it is important to receive the injections regularly and on time as mentioned by the physician.
b.) Missing a dose
