Hydrocortisone acetate suppository formulation for treatment of disease
The present invention relates, in various embodiments, to formulations comprising hydrocortisone and silicon dioxide. In additional embodiments, the invention relates to suppositories comprising hydrocortisone and silicon dioxide. The formulations of the present invention are useful for administration to patients who have gastrointestinal diseases and disorders such as, for example, inflammatory bowel disease.
1. A suppository having a weight of about 2 g and comprising about 90 mg hydrocortisone acetate, about 5 mg to about 20 mg colloidal silicon dioxide and an oleaginous base that includes triglycerides, wherein the suppository releases at least about 80% of the hydrocortisone acetate at about 180 minutes following exposure to dissolution media comprising a buffered 5% w/v sodium lauryl sulfate solution having a final pH in the range of about 6.8-7.0.
2. The suppository of claim 1 , comprising about 14 mg colloidal silicon dioxide.
3. The suppository of claim 1 , wherein the oleaginous base is a semi-synthetic glyceride base comprising saturated C8-C18 triglyceride fatty acids and lecithin.
4. The suppository of claim 1 , wherein the oleaginous base comprises at least about 85% triglycerides, and further comprises diglycerides and monoglycerides.
5. The suppository of claim 1 , further comprising about 0.01 mg to about 0.2 mg butylated hydroxytoluene (BHT).
6. The suppository of claim 1 , wherein the suppository releases the hydrocortisone acetate upon exposure to rectal fluid.
7. The suppository of claim 1 , wherein the suppository has a melting temperature in the range of about 37° C. to about 39° C.
8. The suppository of claim 1 , wherein the suppository is stable under storage conditions at a temperature in the range of about 25° C. to about 40° C.
9. A formulation comprising about 0.5% to about 5% by weight hydrocortisone acetate, about 0.1% to about 5% by weight colloidal silicon dioxide and a semi-synthetic glyceride base comprising saturated C8-C18 triglyceride fatty acids and lecithin, wherein the formulation has a melting temperature in the range of about 37° C. to about 39° C.
10. The formulation of claim 9 , comprising about 4.5% by weight hydrocortisone acetate and about 0.7% by weight colloidal silicon dioxide.
11. The formulation of claim 9 , wherein the base comprises at least about 85% triglycerides, and further comprises diglycerides and monoglycerides.
12. The formulation of claim 9 , wherein the formulation releases the hydrocortisone acetate upon exposure to rectal fluid.
