Dexamethasone teratogenic effects

Albendazole is contraindicated in patients with known hypersensitivity to the drug and during pregnancy (Category C). The drug has exhibited embiyotoxic and teratogenic effects in experimental animals. Albendazole is used cautiously in patients witii hepatic impairment and during lactation. The effects of albendazole are increased with dexamethasone and cimetidina... 

The thalidomide analogs CPS49 (30) and CPS11 (31) have been reported to inhibit PI3/AKT signaling in multiple myeloma cells via an anti-angiogenic effect. These compounds are devoid of the teratogenic properties seen with thalidomide and are currently in preclinical development [66]. Compound 30, and to a lesser extent 31, induced a dose-dependent inhibition of proliferation in several multiple myeloma cell lines and reduced phospho-AKT levels [66]. These compounds also inhibited DNA synthesis in cell lines resistant to conventionally used anti-multiple myeloma drugs (e.g. dexamethasone, anthracyclines and melphalan) in a dose-dependent manner. 

Lenalidomide, a derivative of thalidomide, was introduced in 2004. Patients with multiple myeloma stage II/III, who have undergone at least one previous treatment can be treated with bortezomib or with lenalidomide in combination with dexamethasone. There is good oral absorptin with peak plasma levels at 0.5-4 hours. Lenalidomide is maily eliminated by the kidneys with a half-life of circa 3-9 hours. Teratogenicity cannot be excluded. Side effects include thrombosis, pulmonary embolus, and hepato-toxicity, as well as bone marrow toxicity resulting in neutropenia and thrombocytopenia.
