Silicone-based sustained- and controlled-release drug delivery systems was written by Pfister, William R.;Sweet, Randall P.;Walters, Patrick A.. And the article was included in National SAMPE Symposium and Exhibition, [Proceedings] in 1985.Application In Synthesis of Piperazine Dihydrochloride This article mentions the following:
The effects of various classes of therapeutic agents and pharmaceutical excipients on the cure profile and phys. properties of vulcanized liquid silicone rubber (LSR) were evaluated. The results demonstrate the compatibility of LSR as a carrier matrix for a number of classes of therapeutic agents and pharmaceutical excipients. The resultant phys. properties of the LSR drug/excipient matrix are dependent upon the chem. structure and weight percentage loading level of the additive. These studies demonstrate the utility of LSR for fabricating controlled-release drug delivery systems. In the experiment, the researchers used many compounds, for example, Piperazine Dihydrochloride (cas: 142-64-3Application In Synthesis of Piperazine Dihydrochloride).
Piperazine Dihydrochloride (cas: 142-64-3) belongs to piperazine derivatives. Industrial applications of piperazine include the manufacture of plastics, resins, pesticides and brake fluids. Two common salts in the form of which piperazine is usually prepared for pharmaceutical or veterinary purposes are the citrate, 3C4H10N2.2C6H8O7 (i.e. containing 3 molecules of piperazine to 2 molecules of citric acid), and the adipate, C4H10N2.C6H10O4 (containing 1 molecule each of piperazine and adipic acid).Application In Synthesis of Piperazine Dihydrochloride
