4-Amino(alkyl)cyclohexane-1-carboxamide compounds of the formula (I) (see fig. I) wherein each symbol is as defined in the Specification, isomers thereof and pharmaceutically acceptable acid addition salts thereof. The 4-amino(alkyl)cyclohexane-1-carboxamide compounds, isomers thereof and pharmaceutically acceptable acid addition salts thereof of the present invention have potent and long-lasting coronary, cerebral, renal and peripheral blood flow increasing actions and are less toxic, and thus are useful as a potent and long-lasting antihypertensive agent and an agent for the prevention and treatment of diseases in the circulatory organs such as coronary, cerebral, renal and peripheral arteries. Moreover, the compounds of the present invention exhibit inhibitory action on experimental asthma of guinea pigs, which is caused by histamine inhalation, and inhibitory action on contraction of trachea strips isolated from guinea pigs, which is caused by acetylcholine, and thus are useful as therapeutic agents for asthma.

4-Amino(alkyl)cyclohexane-1-carboxamides de formule (I) (voir fig. I), où chaque symbole est défini dans la spécification; leurs isomères et leurs sels d'addition avec un acide, acceptables en pharmacie. Dans la présente invention, ces 4-amino(alkyl)cyclohexane-1-carboxamides, leurs isomères et leurs sels d'addition avec un acide, acceptables en pharmacie, augmentent sensiblement et de façon durable la circulation sanguine coronarienne, cérébrale, rénale et périphérique; ils sont moins toxiques et, par conséquent, des agents antihypertenseurs puissants et à effet prolongé; ce sont également des agents pour la prévention et le traitement de maladies au niveau d'organes de circulation, comme les artères coronariennes, cérébrales, rénales et périphériques. De plus, les composés de la présente invention exercent une action inhibitrice sur l'asthme expérimental chez des cochons d'Inde, provoqué par l'inhalation d'histamine, ainsi qu'une action inhibitrice sur la contraction de bandes de trachée provenant de cochons d'Inde, causée par l'acétylcholine, ce qui les rend utiles comme agents thérapeutiques pour l'asthme.
