Would purchasing 5 micrograms of CYP2D6 and trying to convert codeine to morphine at home work?

It’s perhaps more serious chemistry than most people are capable or interested in, but there is a simple, two step process for making a mixture of dihydroheroin and 6-monoacetyldihydromorphine (its main metabolite and equally active) as HBr salts suitable for injection or smoking. 1. Codeine freebase converted to dihydrocodeine base…

Meta-analysis of CYP2C19 and CYP2D6 metabolic activity on antidepressant response from 13 clinical studies using genotype imputation

Abstract Cytochrome P450 enzymes including CYP2C19 and CYP2D6 are important for antidepressant metabolism and polymorphisms of these genes have been determined to predict metabolite levels. Nonetheless, more evidence is needed to understand the impact of genetic variations on antidepressant response. In this study, individual clinical and genetic data from 13…

Active pharmaceutical ingredients (APIs) are often lipophilic and thus cannot be easily excreted from the body. They are, therefore, transformed by drug metabolizing enzymes (DMEs) into more hydrophilic metabolites [1]. Generally speaking, drug…
