Antihistamines of the formula ##STR1## wherein ##STR2## is a 5 or 6 membered ring which is phenyl or heterocyclic; ##STR3## is a six membered ring which is 2,3 or 4 pyridyl or is phenyl or substituted phenyl, with the proviso that is ##STR4## is a nitrogen containing ring, ##STR5## must be phenyl; Z is an alkylene chain having 0 to 2 carbon atoms in the chain, said 2 carbon chain optionally having one double bond, said chain optionally having either a carbonyl oxygen, or a hydroxy group as a substituent; W is ##STR6## wherein p is 1 or 2 and n is 1 or 2, R.sup.1 is C.sub.1 to C.sub.6 alkyl, R.sup.2 is hydrogen or C.sub.1 to C.sub.6 alkyl, and the dotted line represents an optical double bond, R.sup.2 being absent if the double bond is present, and Y is substituted carboxylate or substituted sulfonyl. Said antihistamines have little or no sedative effects.
式##STR1##所示的抗组胺药,其中##STR2##是一个5或6元环,该环为苯基或杂环;##STR3##是一个六元环,该环为2、3或4位吡啶基,或为苯基或取代苯基,但条件是如果##STR4##是一个含氮环,##STR5##必须是苯基;Z是一个含有0至2个碳原子的亚烷基链,该2碳链可选择性地含有一个双键,该链可选择性地含有一个羰基氧或一个羟基作为取代基;W是##STR6##其中p是1或2,n是1或2,R.sup.1是C.sub.1至C.sub.6的烷基,R.sup.2是氢或C.sub.1至C.sub.6的烷基,虚线表示光学双键,如果存在双键,则R.sup.2不存在,Y是取代的羧酸酯或取代的磺酰基。这些抗组胺药几乎没有或完全没有镇静作用。
