GAMBARAN POLA PERESEPAN ANTIBIOTIK DI PUSKESMAS MATARAM PERIODE AGUSTUS � DESEMBER 2013

Chitosan is a natural polymer and it is biodegradable polysaccharide, nontoxic, unfold tight junction, mucoadhesive and increase drug absorbtion. Long chains chitosan has properties that are less profitable, because of its poor solubility in water and high viscosity. Thus, in this research, chitosan...
