The present invention relates to the field of pharmaceutical technology and describes a novel advantageous preparation for an active ingredient. The novel preparation is suitable for producing a large number of pharmaceutical dosage forms. In the new preparation an active ingredient is present essentially uniformly dispersed in an excipient matrix composed of one or more excipients selected from the group of fatty alcohol, triglyceride, partial glyceride and fatty acid ester.
Targetable diagnostic and/or therapeutically active agents, e.g. ultrasound contrast agents, comprising a suspension in an aqueous carrier liquid of a reporter comprising gas-containing or gas-generating material, said agent being capable of forming at least two types of binding pairs with a target.
Compounds of formula (I) especially where R
1
is an optionally substituted alkyl, aralkyl or heterocyclyl-alkyl group, are shown to have activity as sodium channel blockers or as antifolates. Some novel compounds where R
1
is an aralkyl or hetero-cyclyl-alkyl are disclosed.
