Abstract: The present invention relates to a pharmaceutical carrier composition and a pharmaceutical composition comprising said pharmaceutical carrier composition. The pharmaceutical composition comprises: (a) at least 20% (w/w) of the composition of a sugar or a sugar alcohol; (b) one or more pharmaceutically acceptable excipients; (c) one or more pharmaceutically active ingredients in their base form; and (d) water up to 100% (w/w). The present pharmaceutical composition is especially resistant against flocculation, clumping and/or precipitation at room temperature during prolonged time-periods such as one or more years.
Abstract: The present invention relates to compounds with an increased in vivo biological activity, and especially an increased pharmaceutical activity, such as an anti-nematodal or antifungal activity, an immunosuppresive activity, a metabolism influencing activity and/or an anti-cancer activity. Specifically, the present invention relates to compound comprising an artemisinin derivative according to the general formula (I) covalently linked at the 1 or the 2 position to a compound with a biological activity thereby increasing the biological activity of said compound or a pharmaceutically acceptable salt thereof.
