This invention herein describes a method of facilitating the entry of drugs into cells and tissues at pharmokinetically useful levels and also a method of targeting drugs to specific organelles within the cell. This polar lipid/drug conjugate targeting invention embodies an advance over other drug targeting methods because through this method, intracellular drug concentrations may reach levels which are orders of magnitude higher than those achieved otherwise. Furthermore, it refines the drug delivery process by allowing therapeutic agents to be directed to certain intracellular structures. This technology is appropriate for use with antiproliferative, antibiotic, antimycotic, antiviral and antineoplastic drugs, in particular in combination with a multiplicity of other emollients and agents to make up topically-active substances such as salves, for rapid and efficient introduction of such agents through the epidermis for treatment of skin diseases and other disorders.
A pharmaceutical composition comprising an antiproliferative, antibiotic, antimycotic, antiviral or antineoplastic drug, a polar lipid carrier, two linker functional groups and a spacer, wherein the spacer has a first end and a second end and wherein the polar lipid is attached to the first end of the spacer through a first linker functional group and the drug is attached to the second end of the spacer through a second linker functional group, the composition further comprising a medicinal ointment or salve.
A pharmaceutical composition comprising an antiproliferative, antibiotic, antimycotic, antiviral or antineoplastic drug having a first functional linker group, and a polar lipid carrier having a second functional linker group, wherein the drug is covalently linked to the polar lipid carrier by a chemical bond between the first and second functional linker groups, the composition further comprising a medicinal ointment or salve.
