  • Patent number: 6048845
    Abstract: Compositions of matter comprising a substituted cyclodextrin and cytotoxic compound, especially cytotoxic drugs such as antibiotic, anti-fungal and anti-neoplastic, drugs are claimed. The compositions cause significantly less ulceration compared to the same formulation of cytotoxic compound without cyclodextrin compound when extravasated. The compositions may also cause less vascular irritation compared to the same formulation of cytotoxic compound without cyclodextrin when administered intravenously without extravasation. Compositions of matter comprising watersoluble cytotoxic agents, especially anticancer drugs and anti-ulceration effective or anti-irritatioin effective amounts of cyclodextrin compounds are also claimed. Methods for reducing the likelihood of ulceration and or irritation when administering the compositions according to the invention are also disclosed and claimed.

  • Patent number: 5824668
    Abstract: Disclosed are compositions including at least one 5.beta. steroid and an amorphous cyclodextrin. Also disclosed are methods for treating a condition such as obesity, diabetes syndrome, diabetes-associated hypercorticoidism, combinations thereof, and anemic disorders by administering to a mammal in need of such treatment a composition including an obesity-, diabetes-, or anemia antagonistic amount of at least one 5.beta. steroid and an amorphous cyclodextrin. Furthermore, disclosed are methods for treating a subject for a condition that responds to treatment with DHEA by administering to the subject at least one 5.beta. steroid and DHEA in an amount that minimizes the contribution of the DHEA to the production of testosterone and estradiol while maximizing an amount of .alpha.ET and .beta.ET circulating in the subject's blood from an initial dose administered to the subject.
