A unique pharmaceutical delivery system comprising a physiologically acceptable nonaqueous liquid such as an edible oil and a thickening agent such as colloidal silicon dioxide which together form a semi-solid having the consistency of a pudding is provided. This novel system masks unacceptable taste, does not adversely affect the stability of the drug, and accommodates large doses. Its primary advantage is its ease of administration to very young or debilitated patients.

Why it's free to use
- Filed October 11, 1989. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended October 11, 2009.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 11, 2011.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
