The invention relates to novel N-(substituted phenyl)-N′-[&ohgr;-(3-substituted phenyl-4-isoxazolecarbonylamino)alkyl]piperazines, their N-oxides, and pharmaceutically acceptable salts thereof. The compounds are endowed with enhanced selectivity for alpha1-adrenergic receptors and a low activity in lowering blood pressure. The compounds are useful in the treatment of obstructive syndromes of the lower urinary tract, including benign prostatic hyperplasia (BPH), and in the treatment of lower urinary tract symptoms (LUTS) and neurogenic lower urinary tract dysfunction (NLUTD), and other conditions.

Described are derivatives with an adrenergic antagonistic activity and, in particular, high selectivity for &agr;
1a
- and &agr;
1d
-adrenergic receptors compared to &agr;
1b
-receptors. This selectivity profile suggests the use of these derivatives in the treatment of symptoms of the lower urinary tract, including those associated to benign prostatic hyperplasia, without the side effects associated with hypotensive activity.
