This chapter will start out by contemplating a variety of routes of administration. Other pharmacokinetic difficulties, such as drug absorption, distribution, and storage, will then be addressed. Drug metabolism are going to be covered in the following chapter.
Period II biotransformations entail reactions that couple the drug molecule with A different molecule inside of a procedure termed conjugation. Conjugation generally renders the compound pharmacologically inert and h2o-soluble so it might be quickly excreted.
An illustration of a Phase I biotransformation is when diazepam, a medication prescribed for stress, is reworked into desmethyldiazepam and after that to oxazepam. Both equally these metabolites produce comparable physiological and psychological results of diazepam.[three]
