Maribavir isomers, compositions, methods of making and methods of using
The invention relates to novel compositions and methods of using maribavir which enhance its effectiveness in medical therapy, as well as to maribavir isomers and methods of use thereof for counteracting the potentially adverse effects of maribavir isomerization in vivo in the event it occurs.
1. A composition comprising maribavir and at least one of an antacid which is effective for neutralizing acid that catalyzes isomerization of maribavir, (ii) an antibiotic having activity against a microorganism that mediates isomerization of maribavir, or (iii) an antagonist that inhibits metabolism that induces isomerization of maribavir, said isomerization producing a decrease in the therapeutic efficacy of maribavir.
2. The composition of claim 1 , wherein said composition comprises maribavir and an antacid which is effective for neutralizing acid that catalyzes isomerization of maribavir.
3. The composition of claim 1 , wherein said composition comprises maribavir and an antibiotic having activity against a microorganism that mediates isomerization of maribavir.
4. The composition of claim 1 , wherein said composition comprises maribavir and an antagonist that inhibits metabolism that induces isomerization of maribavir, said isomerization producing a decrease in the therapeutic efficacy of maribavir.
5. The composition of claim 1 , wherein said composition comprises at least 100 mg of maribavir.
6. The composition of claim 5 , wherein said composition comprises up to 3200 mg of maribavir.
7. The composition of claim 1 , wherein said composition is an immediate release formulation, a delayed release formulation, a controlled release formulation or an intravenous formulation.
8. The composition of claim 1 , wherein said composition is formulated for oral administration.
9. The composition of claim 1 , wherein said composition is formulated for intravenous administration.
