Introduction To Bioavailability And Pk Bioanalysis In Drug Development

Pharmacokinetic studies provide the basis for determining drug exposures in the body over time. PK parameters are used to evaluate the absorption, distribution, metabolism, and excretion (ADME) processes of drugs. These ADME processes are affected by physicochemical activities including lipophilicity, molecular weight and water solubility. An understanding of these characteristics is key to designing a successful drug treatment. Absorption is the first topic of pharmacokinetic studies. PK lab testing can be conducted using a variety of methods including oral, nasal, dermal, or parenteral methods of administration. Physicochemical parameters of the drug and the concentration of the drug at the site of absorption will affect how quickly it reaches your bloodstream.

Pk bioanalysis provides the basis for determining drug exposures in the body over time. The ability of a pharmaceutical product to complete its intended therapeutic action and reach its maximum effectiveness depends on how well it is absorbed, distributed, metabolized, and excreted. PK parameters are used to evaluate both ADME processes and their effects on therapeutic outcome.Based on the results of PK studies, a drug’s rate of absorption, its absorption half-life, and time to peak concentration can be determined. These parameters are used for the evaluation of ADME processes such as distribution. Distribution involves the movement of drugs throughout different body compartments including the blood, lungs, adipose tissue, and skin.

Generic drugs contribute to modern healthcare by accomplishing effective, safe, and low- cost alternatives to currently available modern medicines. For drugs beyond their period of patent exclusivity insurers and patients often prefer the lower cost alternative of generics. If you trace back the evolution of the pharmaceutical industries, it is visible that the production and sale of generic medications have increased in recent years. Also, the U.S. Food & Drug Administration has prioritized the discovery, development, and approval of new pharmaceutical products, allowing for more rapid testing and approval of generic drugs with proof of bioequivalence to the original reference product.

Bioequivalence definition: A bioequivalent drug has the same delivery and effectiveness as an innovative medicine.

Generic drugs are vital to the success of modern healthcare. With the increasing popularity of generics, new testing procedures have been put in place to ensure that their effect is equal to their original counterparts. Bioequivalence studies have been implemented to ensure that they are capable of delivering consistent levels of active ingredient. Due to these regulations, it is important for pharmacists and other healthcare professionals to know how to carry out these tests with precision and accuracy so that patients receive safe and effective treatment.
