Methods of treating congestive heart failure in a mammal, especially a human, by co-administration of (1) amlodipine, a pharmaceutically acceptable salt of amlodipine; (2) an ACE inhibitor; and optionally (3) a diuretic and/or (4) digoxin.

Composition containing amlodipine or a pharmaceutically acceptable salt thereof, and an ACE inhibitor

Certain carboxylic acids of the formula ##STR1## and the pharmaceutically-acceptable salts thereof, and certain esters and amides thereof, are useful for inhibiting the degradation of articular cartilage when administered to a mammalian subject afflicted with an arthritic disease. X is O, S, SO, SO.sub.2, NH, NCH.sub.3 or NCOCH.sub.3 ; and n is zero or one.

Method for inhibiting the degradation of cartilage

Novel trans-isomeric derivatives of 4-phenyl-1,2,3,4-tetrahydro-1-naphthalenamine are useful as antidepressant agents. These novel compounds act to block the synaptosomal uptake of norepinephrine and serotonin (5-hydroxy-tryptamine), thereby alleviating abnormalities at central receptor sites. The preferred embodiment is the enantiomer trans-(1R)-N-methyl-4-(3,4-dichlorophenyl)-1,2,3,4-tetrahydro-1-naphthalen amine and its pharmaceutically acceptable acid addition salts.

Antidepressant derivatives of

Novel cis-isomeric derivatives of 4-phenyl-1,2,3,4-tetrahydro-1-naphthalenamine are useful as antidepressant agents. These novel compounds act to block the synaptosomal uptake of serotonin (5-hydroxy-tryptamine), thereby alleviating serotonin abnormalities at central receptor sites. The preferred embodiment is the enantiomer cis-(1S)-N-methyl-4-(3,4-dichlorophenyl)-1,2,3,4-tetrahydro-1-naphthalenam ine and its pharmaceutically acceptable acid addition salts.

1-Benzyl- and 1-phenyl-4-(2-hydroxy-3-benzyloxypropyl)-piperazines useful as immune regulants are disclosed. Also disclosed are pharmaceutical compositions containing the novel compounds and a method of regulating immune response of a warm blooded animal by administration of the novel compounds.

Substituted piperazines having immune regulant activity

1-(2-Hydroxy-3-n-alkoxypropyl)-4-substituted-piperazines and piperidines and derivatives thereof useful as immune regulants are disclosed. Also disclosed are pharmaceutical compositions containing the novel compounds and a method of regulating the immune response of a subject by administration of the novel compounds.

1-(2-Hydroxy-3-n-alkoxypropyl)-4-substituted piperidines, pharmaceutical

Novel compounds derived from formylphenoxyacetic acid such as N,N-dihexadecyl-4-(aminomethyl)phenoxy acetamide and N,N-dihexacecyl-2-(4-(aminomethyl)phenoxy) ethylamine and their non-toxic acid addition salts are useful for combating viral infections in vertebrate animals.

Compounds derived from formylphenoxyacetic acid as antiviral agents in

Novel amine and amidine derivatives of di-O-(n-higher alkyl and alkenyl)-glycerols and -propanediols, and their pharmaceutically acceptable acid addition salts, are useful for combating viral infections in mammals. Of particular interest is 1,3-di-O-(n-hexadecyl)-2-O-(3-aminopropyl)-glycerol, and its pharmaceutically acceptable acid addition salts.

Antiviral amine and amidine derivatives of glycerol and propanediols

1-(2-Hydroxy-3-n-alkoxypropyl)-4-substituted-piperazines and piperidines

Novel amine and amidine derivatives of di-0-(n-higher alkyl and alkenyl)-glycerols and -propanediols, and their pharmaceutically acceptable acid addition salts, are useful for combating viral infections in mammals. Of particular interest is 1,3-di-0-(n-hexadecyl)-2-0-(3-aminopropyl)-glycerol, and its pharmaceutically acceptable acid addition salts.

Antiviral amine derivatives of glycerol and propanediols

The novel N,N-bis(higher-n-alkyl)aminomethylphenylethanolamines and their mineral acid and organic acid salts are useful for preventing viral infections in mammals and also for stimulating cellular mediated immune response.

N,N-Disubstituted aminomethylphenylethanolamines

Antiviral amine derivatives of propanediols

Novel 1,2- and 1,3-(di-O-n-alkyl)glycerol derivatives and their pharmaceutically acceptable acid addition salts are useful as non-specific stimulants of cell-mediated immunity.

Di-O-n-alkyl glycerol derivatives as immune stimulants

Novel �N,N-di(higher alkyl)aminomethyl!benzamidine and substituted compounds such as �N,N-di(higher alkyl)aminomethyl!-N-(2-propyl)-benzamidine and �N,N-di(higher alkyl)aminomethyl!-N-(p-hydroxyphenyl)-benzamidine and their non-toxic acid addition salts are useful for combating viral infections in vertebrate animals.
