The science and technology associated with pharmacy has progressed enormously over the past few decades. These are extremely weak and cannot be analysed using normal titrimetric methods.

Pharmacokinetic Drug Interactions Factors contributing to drug interactions Mechanisms of drug interactions Reducing the risk of drug interactions Questions.

A brief mention brahmxnkar Bioactivation and Tissue Toxicity has been included at the end of this chapter so that after understanding the mechanisms of drug metabolism, a student will be better placed to appreciate their significance.

The optimized formulation of present study exhibited desired controlled drug release characteristics in the alkaline pH conditions and at acidic environment the drug dissolution was minimal as intended. Compartment Modelling One-compartment open model Intravenous bolus administration Intravenous infusion Extravascular administration Urinary excretion data Multicompartment models Two compartment open model Intravenous bolus administration Intravenous infusion Extravascular administration Questions A brief description of methods usually employed to enhance the bioavailability of a drug from its formulation has been included.

Hence the non-aqueous titrimetric method is used.

Popular posts from this blog Non-aqueous Titrations. This system ensures the drug release at the alkaline pH region where the drug has got maximum solubility. In Folin and Flanders titrated the acidic substances by using the non-aqueous solvents such as benzene, chloroform and chloroform-methanol mixture.

The study carried out here was focused on developing conventional monolithic controlled release matrix tablet of Atorvastatin calcium using carbomer as release controlling polymer. Figg, Hao Zhu, Kenneth S. In this method, the primary aromatic amine is reacted with the sodium nitrite in acidic medium to form a diazonium salt.

A thorough background of the fate of drug after its administration; the rate processes to which it is subjected in the body and its behavior after biotransformation, are thus very essential in addition to the knowledge about its pharmacodynamics.
