Embodiment 1

[0110] Example 1: In vitro lipolysis experiment of rat adipocytes with β agonists and glucocorticoids

[0111] Glycerol was detected spectrophotometrically in cell culture media following chemical oxidation with hydrogen peroxide in bulk in vitro lipolysis experiments. Glycerol was assayed within 3 hours. Lipolysis levels were measured in cultured human adipocytes following one or more pre-incubation periods of exposure to beta agonists alone, glucocorticosteroids alone, or a combination of both, see below for more details . Preadipocytes are isolated and differentiated into adipocytes:

[0112] Human subcutaneous adipocytes were used in lipolysis experiments. Adipose tissue was collected by liposuction or lipectomy and preadipocytes were isolated as follows. Briefly, adipose tissue was minced and placed in a shaking chamber enriched with oxygen (5% CO 2 ; 75 times / min), incubate at 37°C for 1 hour in Krebs-Ringer bicarbonate buffer containing 1% bovine serum albumin an...

Embodiment 2

[0120] Example 2: Inhibition of lipogenesis by beta agonists and glucocorticoids

[0121] Non-limiting examples of such adipogenesis inhibition are as follows: Cell culture: 3T3-L1 preadipocyte cell line (ATCC, Manassas, VA) was divided into 4×10 5 Cells / T75ml flasks were inoculated into Dulbecco's Modified Eagle Medium (DMEM) containing 10% normal bovine serum and 1% penicillin / streptomycin antibiotics. Cells were incubated at 37°C, 5% CO 2 incubate. After 3 days, the cells were detached with trypsin, counted, and resuspended in a medium containing 6 × 10 5 Cells / well in 2 ml of medium in a 24-well plate. After 1-2 days, the cells are close to confluence and ready to initiate adipogenesis. Lipogenetic material: lipogenesis priming medium : DMEM / 10% fetal bovine serum / 0.5mM IBMX / 1μM dexamethasone adipogenesis medium : DMEM / 10% fetal bovine serum / 10μg / ml insulin lipogenesis maintenance medium : DMEM / 10% fetal bovine serum Negative Control Medium : DMEM / 10% normal ...

Embodiment 3

[0122] Example 3: Beta-2 Agonist Combination with Glucocorticosteroids Reduces Epididymal Fat Pad Mass

[0123] We sought to determine whether glucocorticosteroids reduce fat in vivo in a manner consistent with the in vitro lipolysis data described in Example 1. To this end, we measured epididymal fat pad mass in rats treated with the long-acting β-2 adrenergic agonist formoterol alone and in combination with budesonide.

[0124] Male Sprague Dawley rats (-500 g) were anesthetized in 4% isoflurane using a Matrx 3000 vaporizer. Then, inject 0.4 ml of vehicle (2% PEG) at the front 5 mm of the rear end of the fat pad to the animals listed in Table 2 below; formoterol in vehicle (3.48 μg / ml; dose=1.39 μg); or Formoterol (3.48 μg / ml) plus budesonide (10 μg / ml; dose = 1.39 μg formoterol, 4 μg budesonide). Each animal received drug treatment on one side and vehicle (2% PEG) on the opposite side; groups were balanced for drug and vehicle (see Table 2).

[0125] Injections were ...

Abstract

Compositions, formulations, methods, and systems for treating regional fat deposits and fat-related conditions, dermal conditions, and muscular conditions. Methods comprise administering a composition comprising at least one compound that reduces desensitization of beta adrenergic receptors, for example a glucocorticosteroid, and / or at least one long-acting beta-2 adrenergic receptor agonist, for example, formoterol. Compositions to be administered include sustained release formulations comprising at least one long-acting beta-2 adrenergic receptor agonist, at least one compound that reduces desensitization of beta adrenergic receptors, or both in a sustained crystalline microparticle form.

Description

[0001] cross reference [0002] This application claims the benefit of U.S. Provisional Patent Application Serial Nos. 60 / 852,221, filed October 17, 2006, 60 / 898,009, filed January 29, 2007, and 60 / 919,011, filed April 13, 2007, which Incorporated herein by reference in its entirety. Background of the invention [0003] Graves' disease is a common disease with an incidence rate of 1 / 1000 women per year. In addition to hyperthyroidism, 25-50% of individuals with Graves' disease progress to clinically involving the eye, ie, thyroid eye disease. Graves' Ophthalmopathy (GO) is a typical form of thyroid eye disease. While some GO patients suffer only mild ocular discomfort, 3-5% suffer from severe pain and inflammation with diplopia and even vision loss. [0004] The clinical symptoms and signs of GO can be explained mechanistically as a marked increase in tissue volume within the bony orbit. Enlargement of the orbital tissue causes the globe to move forward, and outflow from t...
