Rifampicin is an antibiotic that potently inhibits RNA polymerase and blocks RNA synthesis in Escherichia coli. Rifampicin has been shown to inhibit α-synuclein fibrillation and disaggregate fibrils in a concentration-dependent manner. Data indicates that Rifampicin can activate the nuclear pregnane X receptor, which affects cytochrome P450, and the activity of glucuronosyltransferases and P-glycoprotein. Rifampicin has been shown to enhance CYP2C-mediated metabolism, affect compounds that are transported by P-glycoprotein and metabolized by CYP3A4. Rifampicin has been used in tuberculosis studies.

I prepared 150 mg/ml stock solution of Rifampin (Rifampicin from MP biomedicals) by using methanol, in this solution it is not 100% dissolved for 150mg/ml. kindly suggest how to prepare 150mg/ml stock and by using which solvent?
