<p>The present invention relates to pharmaceutical compositions comprising an NK1 receptor antagonist and a sodium channel blocker compound of formula (I) wherein R<SUP>1</SUP> and R<SUP>2</SUP> are independently hydrogen, C<SUB>1-6</SUB>alkyl or C<SUB>3-6</SUB>cycloalkylC<SUB>1-6</SUB>alkyl; or R<SUP>1</SUP> and R<SUP>2</SUP>, together with the nitrogen to which they are attached, may form an unsubstitued 3-, 4-, 5- or 6-membered saturated ring; R<SUP>3</SUP> is C<SUB>1-6</SUB>alkyl, C<SUB>1-6</SUB>haloalkyl, C<SUB>1-3</SUB>alkoxyC<SUB>1-3</SUB>alkyl or C<SUB>1-3</SUB>haloalkoxyC<SUB>1-3</SUB>alkyl; or R<SUP>1</SUP> and R<SUP>3</SUP>, together with the interconnecting atoms, form a saturated or unsaturated 4- to 6-membered ring; X is carbon or nitrogen; n is 0, 1 or 2, wherein when present each R<SUP>4</SUP> is independently selected from the list consisting of C<SUB>1-3</SUB>alkyl, halogen, cyano, haloC<SUB>1-3</SUB>alkyl, hydroxy, C<SUB>1-3</SUB>alkoxy and C<SUB>1-3</SUB>haloalkoxy; q is 1 or 2; either R<SUP>5</SUP> or R<SUP>6</SUP> is -O-R<SUP>7</SUP> or -OCH<SUB>2</SUB>R<SUP>7</SUP>, wherein the other R<SUP>5</SUP> or R<SUP>6</SUP> is hydrogen or R<SUP>4</SUP>; and wherein R<SUP>7</SUP> is either a phenyl ring or a 5- or 6-membered aromatic heterocyclic ring (independently containing one or more nitrogen, sulphur or oxygen atoms) wherein either the phenyl ring or the heterocyclic ring is optionally substituted by one or more groups independently selected from the list consisting of C<SUB>1-3</SUB>alkyl, halogen, cyano, haloC<SUB>1-3</SUB>alkyl, hydroxy, C<SUB>1-3</SUB>alkoxy and C<SUB>1-3</SUB>haloalkoxy; or a pharmaceutically acceptable salt or solvate thereof; as a combined preparation for simultaneous or sequential administration, and to the use of such compositions in the treatment of certain disorders, including epilepsy and mood disorders.</p> |
