Abstract
Aqueous parenteral solutions of drugs which are insoluble or only sparingly soluble in water and/or which are unstable in water, combined with cyclodextrin selected from the group consisting of hydroxypropyl, hydroxyethyl, glucosyl, maltosyl and maltotriosyl derivatives of .beta.- and .gamma.-cyclodextrin, provide a means for alleviating problems associated with drug precipitation at the injection site and/or in the lungs or other organs following parenteral administration.
Claims86
A method for decreasing the incidence of precipitation of a lipophilic and/or water-labile drug occurring at or near the injection site and/or in the lungs or other organs following parenteral administration, said method comprising parenterally administering said drug in an aqueous solution containing from about 20% to about 50% cyclodextrin selected from the group consisting of hydroxyethyl, glucosyl, maltosyl and maltotriosyl derivatives of .beta.-cyclodextrin and hydroxypropyl, hydroxyethyl, glucosyl, maltosyl and maltotriosyl derivatives of .gamma.-cyclodextrin.
A method for decreasing the tendency of a lipophilic and/or water-labile drug to collect in the lungs or other organs due to precipitation at or near the injection site and/or in the lungs or other organs themselves following parenteral administration, said method comprising formulating said drug in an aqueous solution adapted for parenteral administration containing from about 20% to about 50% cyclodextrin selected from the group consisting of hydroxyethyl, glucosyl, maltosyl and maltotriosyl derivatives of .beta.-cyclodextrin and hydroxypropyl, hydroxyethyl, glucosyl, maltosyl and maltotriosyl derivatives of .gamma.-cyclodextrin.
