Xanthine derivatives of the formula I <IMAGE> where at least one of the radicals R<1> and R<3> is a radical of the formula Ia <IMAGE> R<4> is a (C1-C3)-alkyl radical, n is an integer from 2 to 5 and, if only one of the radicals R<1> and R<3> is such a tertiary hydroxyalkyl group of the formula Ia, the other radical is a hydrogen atom or an aliphatic hydrocarbon radical R<5> which has up to 6 C atoms and whose carbon chain can be interrupted by up to 2 oxygen atoms or be substituted by an oxo group or up to two hydroxyl groups, these oxo and hydroxyl groups being separated from the ring nitrogen by at least 2 C atoms, and R<2> is an alkyl group with 1-4 C atoms, are suitable for the preparation of pharmaceutical compositions for the prophylaxis and treatment of muscle damage which may occur after interruption of the blood circulation. |
