As for these chemical compounds it was discovered that effect of the anti- microbial characteristic antiseptic is strengthened. Especially desirable amino alcohol is 2- amino -2- methyl -1- propanol (AMP), 2- dimethyl amino - methyl -1- propane diol (DMAMP), 2- amino -2- ethyl -1,3-...
An anomaly was noted in the release behaviour of a series of high molecular weight FITC‐dextrans from a tablet formulation designed to float in stomach contents. The tablets contained sodium bicarbonate and hydroxypropylmethyl cellulose (HPMC) in a cetyl alcohol matrix. When hydrated in an acid ...
