Chewable gelled emulsions
An oral pharmaceutical composition in unit dose form, each unit dose comprising a lipophilic drug substance within a unitary carrier body, said body comprising a soft, chewable, gelled oil-in-water emulsion.
1. An oral pharmaceutical composition in uncoated dose unit form comprising a physiologically tolerable calcium compound within a unitary carrier body, said body comprising a soft, chewable, gelled oil-in-water emulsion, wherein the calcium compound is dispersed in one or both of the oil and aqueous phases of the emulsion, and wherein the calcium content per dose unit is at least 125 mg Ca, and further wherein the aqueous phase comprises a gelling agent which is a physiologically tolerable polysaccharide and which is present at a concentration of 0.2 to 5% wt. in the aqueous phase, and the weight of the dose unit is 1000 mg to 5000 mg.
2. The composition as claimed in claim 1 , containing particulate calcium carbonate.
3. The composition as claimed in claim 1 , further containing xylitol.
4. The composition as claimed in claim 1 , consisting of said gelled emulsion.
5. A pharmaceutical package comprising a composition as claimed in claim 1 , wherein said composition is foil-encased.
6. The package as claimed in claim 5 , in the form of a blister pack.
7. The composition as claimed in claim 1 , wherein the physiologically tolerable polysaccharide is a carrageenan, an alginate, an agar, a chitosan, a pectin, a gellan or a scleroglucan.
8. The composition as claimed in claim 1 , wherein the dose unit has a compression breaking strength of greater than 500 g/cm 2 .
9. The composition as claimed in claim 1 , wherein the gelled oil-in-water emulsion may be compressed at least substantially reversibly by at least 10% upon application of a force-deformation gradient of 0.1 mm/s at 21° C., 50% relative humidity and atmospheric pressure.
