Abstract
This invention relates to triazolo-pyrimidine derivatives corresponding to the following formula: ##STR1## wherein X represents a 2-pyridyl, 3-pyridyl or 4-pyridyl nucleus optionally substituted by at least one straight-chained or branched C.sub.1-4 alkoxy or alkyl or a hydroxy or cyano group, PA0 R.sub.1 represents hydrogen or a straight-chained or branched saturated or unsaturated C.sub.1-5 aliphatic group, and PA0 R.sub.2 represents a straight-chained or branched C.sub.1-4 alkyl group, and the pharmaceutically acceptable acid addition salts thereof with inorganic or organic acids. These compounds may be used in therapy, particularly on account of their cardiotonic activity.
