Abstract
A SEDDS or SMEDDS or SNEDDS formulation for drug delivery of a lipophilic therapeutic agent, providing enhanced modulation of solubility, stability, absorption, metabolism, and/or pharmacokinetic profile of the therapeutic agent by formulation with a lipophilic surfactant, a hydrophilic surfactant, one or more solubilizers and, optionally, digestible oils, resulting in higher bioavailability of the therapeutic agent administered to a subject in need of such therapeutic 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 (12)
1. A pharmaceutical composition comprising:
(a) 2.5-37.5 percent by weight of a solubilized testosterone undecanoate (TU);
(b) 5-37.5 percent by weight of a hydrophilic surfactant selected from the group consisting of polyoxyethylene sorbitan fatty acid ester, hydrogenated castor oil ethoxylate, polyethylene glycol mono- or di-esters of palmitic or stearic acid, fatty acid ethoxylate, or a combination thereof;
(c) 15-65 percent by weight of a hydrophobic surfactant selected from the group consisting of octanoic acid, decanoic acid, undecanoic acid, lauric acid, myristic acid, palmitic acid, stearic acid, oleic acid, linoleic acid, linolenic acid, propylene glycol monolaurate, glycerol/glyceryl monolinoleate, glyceryl mono- and dicaprylocaprate, or a combination thereof;
(d) 5-37.5 percent by weight of one or more phytosterol esters; and
(e) 0-15 percent by weight of dl-alpha-tocopherol;
wherein the composition is a self-emulsifying oral formulation.
2. The pharmaceutical composition of claim 1 , wherein the hydrophilic surfactant is hydrogenated castor oil ethoxylate.
3. The pharmaceutical composition of claim 2 , wherein the hydrogenated castor oil ethoxylate is Cremophor RH40.
4. The pharmaceutical composition of claim 1 , wherein the hydrophobic surfactant is propylene glycol monolaurate.
5. The pharmaceutical composition of claim 4 , wherein the propylene glycol monolaurate is Lauroglycol 90.
6. A method of treating male hypogonadism in a male subject in need thereof, the method comprising administering the pharmaceutical composition of claim 1 to the subject.
