Compositions, systems, and kits for administering zotarolimus and paclitaxel to blood vessel lumens
A system and compositions including zotarolimus and paclitaxel are disclosed, as well as methods of delivery, wherein the drugs have effects that complement each other. Medical devices are disclosed which include supporting structures that include at least one pharmaceutically acceptable carrier or excipient, which carrier or excipient can include one or more therapeutic agents or substances, with the carrier including at least one coating on the surface thereof, and the coating associated with the therapeutic substances, such as, for example, drugs. Supporting structures for the medical devices that are suitable for use in this invention include, but are not limited to, coronary stents, peripheral stents, catheters, arterio-venous grafts, by-pass grafts, and drug delivery balloons used in the vasculature. These compositions and systems can be used in combination with other drugs, including anti-proliferative agents, anti-platelet agents, anti-inflammatory agents, anti-thrombotic agents, cytotoxic drugs, agents that inhibit cytokine or chemokine binding, cell de-differentiation inhibitors, anti-lipaedemic agents, matrix metalloproteinase inhibitors, cytostatic drugs, or combinations of these and other drugs.
1. A pharmaceutical composition, comprising paclitaxel or salts, prodrugs, or derivatives thereof; and zotarolimus or salts prodrugs thereof,
wherein the ratio of zotarolimus:paclitaxel, r, is by weight 10:7≦r≦10:0.01;
wherein if the composition is administered to a subject in a blood vessel on a medical device, the formation of neointimal hyperplasia is reduced; and
wherein the composition is formulated for local delivery to a subject.
2. The composition of claim 1 , wherein r=10:1.
3. The composition of claim 1 , wherein the formulation is associated with a medical device.
4. The composition of claim 3 , wherein the medical device comprises a stent.
5. The composition of claim 4 , wherein the stent comprises at least one coating on a surface, and wherein the coating is associated with the composition.
6. The composition of claim 5 , wherein the concentration of zotarolimus is about 10 μg/mm of stent, and the concentration of paclitaxel is about 1 μg/mm of stent.
7. The composition of claim 1 , wherein the subject is human.
8. The composition of claim 1 , wherein the mode of administration of the therapeutically effective amount of the combination of drugs is one selected from the group consisting of orally, rectally, parenterally, intracisternally, intravaginally, intraperitoneally, topically, bucally, intravenously, intra-arterially, intramuscularly, subcutaneously, intra-articularly, transdermally, and interpericardially.
9. A composition comprising zotarolimus or salts prodrugs thereof; and paclitaxel or salts, prodrugs, or derivatives thereof;
wherein the ratio of zotarolimus:paclitaxel, r, is by weight 10:7≦r≦10:0.01, and
wherein an effect of the zotarolimus complements activity of paclitaxel, and paclitaxel complements activity of zotarolimus when locally administered.
10. The composition of claim 9 , wherein r=10:1.
11. The composition of claim 9 , wherein the formulation is associated with a medical device.
12. The composition of claim 11 , wherein the medical device comprises a stent.
13. The composition of claim 12 , wherein the stent comprises at least one coating on a surface, and wherein the coating is associated with the composition.
14. The composition of claim 13 , wherein the concentration of zotarolimus is about 10 μg/mm of stent, and the concentration of paclitaxel is about 1 μg/mm of stent.
15. The composition of claim 9 , wherein the subject is human.
16. The composition of claim 9 , wherein the mode of administration of the therapeutically effective amount of the combination of drugs is selected from the group consisting of orally, rectally, parenterally, intracisternally, intravaginally, intraperitoneally, topically, bucally, intravenously, intra-arterially, intramuscularly, subcutaneously, intra-articularly, transdermally, and interpericardially.
