Safety Profile
Poison by ingestion. Moderately toxic by skin contact and intraperitoneal routes. Human teratogenic effects by ingestion: developmental abnormalities of the musculoskeletal and cardiovascular systems. Experimental reproductive effects. Questionable carcinogen with experimental tumorigenic and teratogenic data. Human mutation data reported. It was commonly used as a prescription drug in Europe in the late 1950s and early 1960s. Its use was dscontinued because it was lscovered to cause serious congenital abnormalities in the fetus, notably amelia and phocomelia (absence or deformity of the limbs, including hands and feet) when taken by a woman during early pregnancy. When heated to decomposition it emits toxic fumes of NOx. Used as a sedative and hypnotic.

Hazard Information

General Description
Needles or white powder.
Reactivity Profile
Organic amides/imides, such as THALIDOMIDE(50-35-1), react with azo and diazo compounds to generate toxic gases. Flammable gases are formed by the reaction of organic amides/imides with strong reducing agents. Amides are very weak bases (weaker than water). Imides are less basic yet and in fact react with strong bases to form salts. That is, they can react as acids. Mixing amides with dehydrating agents such as P2O5 or SOCl2 generates the corresponding nitrile. The combustion of these compounds generates mixed oxides of nitrogen (NOx).
Air & Water Reactions
Insoluble in water.
Fire Hazard
Flash point data for this chemical are not available; however, THALIDOMIDE is probably combustible.

Questions And Answer

Glutamic acid derivatives
Thalidomide is a kind of synthetic glutamic acid derivatives. At room temperature, it is a kind of white crystalline powder, and is odorless, tasteless, and slightly soluble in water, methanol, ethanol or acetone, highly soluble in dimethylformamide or pyridine, but insoluble in ether, chloroform or benzene.
At 1950s, Germany developed the drug mainly for treating epilepsy. However, due to the lack of efficacy, then it is further used as an adjunct for sleeping while also widely used as antiemetic drug for pregnant women during their pregnancy.
At early 1960s, thalidomide incident---there had been a lot of reports about birth defect caused by thalidomide (such as: short limb malformations, bone defect, ear missing, cleft lip, heart and gastrointestinal tract abnormalities, etc.). Thereby, it was further prohibited by many countries, and subjected to withdrawal from the pharmaceutical market; but scientists did not totally negate thalidomide and continued to carry out in-depth research; there has been much encouraging and promising progress on the pharmacologic mechanisms of immunity, anti-inflammatory, and anti-angiogenic as well as the clinical treatment of various kinds of difficult disease, making people gain new understanding of the functions of thalidomide.
Since the 1970s, with the emergence of the various research progresses of leprosy, rheumatism and various types of cancer, Israel dermatologists had applied thalidomide as a sedative for patients of erythema nodosum leprosy and obtain rapid alleviation of symptoms. After that many patients of erythema nodosum leprosy had received good therapeutic effects. In1998, the FDA approved thalidomide for the treatment of erythema nodosum leprosy.
In 2004, during the American Society of Hematology annual meeting, RaJkumar from the US Mayo Clinic reported the progress of two studies about using thalidomide and its analogs (lenalidomide) in first-line treatment of multiple myeloma. Both thalidomide and its analogs, lenalidomide are effective in the treatment of multiple myeloma with lenalidomide having a better effect than thalidomide.
In May 2006, the US FDA approved it for the treatment of multiple myeloma.
The above information is edited by the chemicalbook of Dai Xiongfeng.
Treatment of rheumatism
Foreign scholars have reported that when using thalidomide for treatment of 7 rheumatoid patients who can’t be cured by various kinds of anti-inflammatory drugs and immune inhibition, the symptoms were alleviated in most cases within a few weeks at the dose in 400~600mg/d. All patients have their erythrocyte sedimentation rate and rheumatoid factor titers either be normalized or be decreased, wherein 1 case of rheumatoid nodules disappeared at 12 weeks. Someone have ever combined thalidomide with methotrexate for treating 7 cases of refractory rheumatoid arthritis, wherein in 5 cases of patient who persists in treatment, 4 cases obtained alleviated joints tenderness and reduced joints swelling feeling within 3 to 9 months.
Thalidomide to treat rheumatism diseases as follows:
1. Behcet's disease.
2. Systemic lupus erythematosus.
3. Rheumatoid arthritis.
4. Erythema nodosum, Crohn's disease.
5. Scleroderma: at 12 weeks after the start of treatment, it can significantly alleviate the symptoms of gastroesophageal reflux, heal duodenal ulcer and lead to hypopigmentation.
6. Adult Still's disease.
7. Refractory ankylosing spondylitis, multiple myeloma (MM).
Clinical treatment of rheumatism should start from small dose at 25--50mg/day per night, gradually increase the amount to 100--200mg/day with the maximum not exceeding 400mg/day.
Side effects
Adverse reactions during the treatment using thalidomide include: drowsiness, dizziness, drowsiness, headache, constipation, nausea, vomiting, dry mouth, dry skin, erythema and papules and vesicular transient rash; but they usually are not serious and can disappear after termination of administration.
The adverse reactions that should be noted is multiple neuritis with the main symptom being a surface or deep sensory loss and muscle weakness; the occurrence of symptoms is not proportional to the dose and duration; the time when the symptoms began to appear also varies greatly; for the cases without treatment termination, such symptoms are irreversible. In addition, leukopenia, abnormal liver function as well as the well-known teratogenic effects also should be taken care. Other rare side effects include bradycardia, edema, abnormal blood clotting, kidney failure, pneumonia, paresthesia, and hypothyroidism.
Chemical Properties
White powder.
It is used as sedative and has certain efficacy in treating various types of leprosy reactions such as fever, erythema nodosum, neuralgia, joint pain, and swollen lymph nodes but has no treatment effect on leprosy.
