Synergising associations characterized in that they are comprised of at least one product having an antagonist activity on NK1 receptors and at least one product having an antagonist activity on NK2 receptors. Said associations are useful in the treatment of diseases involving the substance P and/or neurokinine A.

Phenothiazine derivatives, their preparation and pharmaceutical

Phenothiazine derivatives of general formula (I), in which R is a linear or branched (1 to 6 C) alkyl radical and R.sub.1 and R.sub.2, which may be identical or different, are linear or branched (1 to 4 C) alkyl radicals or form, with the nitrogen atom to which they are attached, a 4- to 7-membered heterocycle, their isomeric forms and mixtures thereof as well as their addition salts with acids, possess analgesic and diuretic activity. ##STR1##

Analgesic phenothiazine derivatives

Phenothiazine derivatives of formula: ##STR1## in which Y is hydrogen or halogen, R.sub.1 and R.sub.2, which may be identical or different, denote alkyl, cycloalkyl-alkyl, hydroxyalkyl or acetyloxyalkyl radicals or form, together with the nitrogen atom to which they are attached, an optionally substituted, saturated or partially unsaturated 4- to 7-membered heterocycle; and either X is oxygen, sulphur or: N-R.sub.4, R is cycloalkyl, phenyl or --CH.sub.2 R.sub.3, R.sub.3 is H, alkyl (1 to 5 C), alkenyl or alkynyl (2 to 4 C), cycloalkyl (3 to 6 C), phenyl, substituted phenyl or a heterocyclic radical, R.sub.4 is H or --CN, except that X is not oxygen if, simultaneously, R.sub.3 is H or alkyl, R.sub.1 and R.sub.2 are alkyl or NR.sub.1 R.sub.2 forms an unsubstituted heterocycle, and Y is H; or X is: N-R.sub.4 and R.sub.4 forms, with R and the neighbouring atoms, an optionally substituted imidazolyl or imidazolinyl radical or a hexahydrobenzimidazolyl radical, in their isomeric forms and mixtures thereof and their acid addition salts are useful as analgesics and diuretics.

Phenothiazine derivatives of formula ##STR1## in which R represents --NR.sub.1 R.sub.2 in which R.sub.1 and R.sub.2, which may be identical or different, are alkyl, hydroxyalkyl or acetyloxyalkyl radicals, or form, together with the nitrogen atom to which they are attached, a heterocycle containing 4 to 7 members which may be substituted by 1 or 2 alkyl, hydroxyalkyl or acetyloxyalkyl radicals, or R represents --N.sup.+ R.sub.1 R.sub.2 R.sub.3 in which R.sub.1 and R.sub.2 are as defined above and R.sub.3 is alkyl or phenylalkyl, their isomeric forms and their mixtures, and their salts, are useful in the field of antidiarrhetics.
