Abstract
A formulation for drug delivery, providing enhanced modulation of solubility, stability, absorption, metabolism, and/or pharmacokinetic profile of a lipophilic therapeutic agent by formulation with sterols and/or sterol esters, resulting in higher bioavailability of a therapeutic agent administered to a subject in need of such therapeutic agent. The formulation contains a therapeutic agent and a sterol or sterol ester, and can, optionally, further contain a solubilizer and/or an enhancing agent. Also described are pharmaceutical compositions containing the formulations and methods of making and methods of using the formulations and pharmaceutical compositions. Formulations of the disclosure can be constituted to minimize the synthesis of dihydrotestosterone when the therapeutic agent includes testosterone or testosterone esters.
Claims (11)
1. A method of treating male hypogonadism in a subject in need thereof, the method comprising administering to the subject the oral formulation comprising:
a) testosterone undecanoate;
b) from about 10% to about 90% by weight of a non-sterol solubilizing agent effective for solubilization of the testosterone undecanoate; and
c) from about 2% to about 45% by weight of a mixture of phytosterol esters, wherein the mixture of phytosterol esters comprises esters of beta-sitosterol and stigmasterol.
2. The method of claim 1 , wherein the oral formulation comprises from 40 to 400 mg of testosterone undecanoate.
3. The method of claim 1 , wherein the oral formulation comprises from 0.1 to 40% by weight testosterone undecanoate.
4. The method of claim 1 , wherein the non-sterol solubilizing agent comprises propylene glycol monolaurate.
5. The method of claim 1 , wherein the non-sterol solubilizing agent comprises polyoxyl 40 hydrogenated castor oil.
6. The method of claim 1 , wherein the oral formulation further comprises alpha-tocopherol or alpha-tocopherol acetate.
7. The method of claim 1 , wherein the oral formulation is self-emulsifying or self-microemulsifying.
