| abstract |
The present invention relates to an injectable pharmaceutical composition with gelling properties containing : - an active principle; a hydrophobic and bio-compatible organic liquid; and an organogelling substance, the molecules of which have the capacity to bind together via bonds of low energy, wherein said organogelling substance is chosen among L-tyrosine derivatives responding to the following formula (I) wherein : .cndot. R1 is an alkyl group containing 1 to 3 carbon atoms, linear or branched; and .cndot. R2 is a hydrophobic group chosen among aliphatic saturated or unsaturated fatty chains or aryl or arylalkyl groups, Its use as a vector for the release of active principles, as well as its process of preparation. |
