Abstract
An amine polymer includes a substituent bound to an amine of the polymer. The substituent includes a quaternary amine-containing moiety having at least one hydrophobic moiety. A method for binding bile salts of bile acids in a mammal includes orally administering to the mammal a therapeutically-effective amount of the amine polymer.
Claims17
A method for binding bile salts in a mammal, comprising the step of orally administering to the mammal a therapeutic amount of a hydrocarbon amine polymer having a substituent bound to an amine of the hydrocarbon amine polymer, the substituent including a quaternary amine-containing moiety that is bound to said amine of the hydrocarbon amine polymer by an alkylene linking group having three or more carbons, said quarternary amine-containing moiety also including at least one terminal hydrophobic alkyl substituent, having between about 6 and 20 carbons.
A method for reducing blood cholesterol in a mammal, comprising the step of orally administering to the mammal a therapeutic amount of a hydrocarbon amine polymer having a substituent bound to an amine of the hydrocarbon amine polymer, the substituent including a quaternary amine-containing moiety that is bound to said amine of the hydrocarbon amine polymer by an alkylene linking group having three or more carbons, said quaternary amine-containing moiety also including at least one terminal hydrophobic alkyl substituent, having between about 6 and 20 carbons.
A method for treating atherosclerosis in a mammal, comprising the step of orally administering to the mammal a therapeutic amount of a hydrocarbon amine polymer having a substituent bound to an amine of the hydrocarbon amine polymer, the substituent including a quaternary amine-containing moiety that is bound to said amine of the hydrocarbon amine polymer by an alkylene linking group having three or more carbons, said quaternary amine-containing moiety also including at least one terminal hydrophobic alkyl substituent, having between about 6 and 20 carbons.
A method for treating hypercholesterolemia in a mammal, comprising the step of orally administering to the mammal a therapeutic amount of a hydrocarbon amine polymer having a substituent bound to an amine of the hydrocarbon amine polymer, the substituent including a quaternary amine-containing moiety that is bound to said amine of the hydrocarbon amine polymer by an alkylene linking group having three or more carbons, said quaternary amine-containing moiety also including at least one terminal hydrophobic alkyl substituent, having between about 6 and 20 carbons.
A method for binding bile salts in a mammal, comprising the step of orally administering to the mammal a therapeutic amount of a poly(allylamine) polymer having a substituent bound to an amine of the poly(allylamine), the substituent including a quaternary amine-containing moiety that is bound to said amine of the poly(allylamine) by an alkylene linking group having three or more carbons, said quaternary amine-containing moiety also including at least one terminal hydrophobic alkyl substituent, having between about 6 and 20 carbons.
A method for reducing blood cholesterol in a mammal, comprising the step of orally administering to the mammal a therapeutic amount of a poly(allylamine) polymer having a substituent bound to an amine of the poly(allylamine), the substituent including a quaternary amine-containing moiety that is bound to said amine of the poly(allylamine) by an alkylene linking group having three or more carbons, said quaternary amine-containing moiety also including at least one terminal hydrophobic alkyl substituent, having between about 6 and 20 carbons.
A method for treating atherosclerosis in a mammal, comprising the step of orally administering to the mammal a therapeutic amount of a poly(allylamine) polymer having a substituent bound to an amine of the poly(allylamine), the substituent including a quaternary amine-containing moiety that is bound to said amine of the poly(allylamine) by an alkylene linking group having three or more carbons, said quaternary amine-containing moiety also including at least one terminal hydrophobic alkyl substituent, having between about 6 and 20 carbons.
A method for treating hypercholesterolemia in a mammal, comprising the step of orally administering to the mammal a therapeutic amount of a poly(allylamine) polymer having a substituent bound to an amine of the poly(allylamine), the substituent including a quaternary amine-containing moiety that is bound to said amine of the poly(allylamine) by an alkylene linking group having three or more carbons, said quaternary amine-containing moiety also including at least one terminal hydrophobic alkyl substituent, having between about 6 and 20 carbons.
A method for reducing plasma lipid content of a mammal, comprising the step of orally administering to the mammal a therapeutically effective amount of a hydrocarbon amine polymer, comprising a substituent bound to an amine of the hydrocarbon amine polymer, the substituent including a quaternary amine-containing moiety that is bound to said amine of the hydrocarbon amine polymer by an alkylen linking group having three or more carbons, said quaternary amine-containing moiety also including at least one terminal hydrophobic alkyl substituent, having between about 6 and 20 carbons that sequesters with high affinity conjugated primary bile acids including conjugated cholic acid and conjugated chenodeoxycholic acid secreted by said mammal, whereby a substantial portion of said conjugated primary bile acids are excreted by the mammal, thereby causing accelerated lipid metabolism and consequent lowering of plasma lipid content of said mammal.
