Pharmacokinetic studies in Boston

Attrition of drug candidates over the course of drug discovery process if the biggest threat plaguing the biopharmaceutical industry. When he timelines gets prolonged and the costs shoot-up, due to the attrition, public health gets affected. The problem often results in the concerns about the public health and safety if the costs and timelines of drug discovery are extended. An early termination of a candidate without the expected qualities will help in reduction of the overall cost of drug R and D. This approach has been proven effective by multiple studies. In order to achieve this it is important to understand the root causes of attrition that have led to drug development failure in the past. A major reason for this attrition is the safety issues that arise during the animal toxicity testing. Pharmacokinetic profile of the compound is important factor in the assessment of the safety of these compounds. Today, Pharmacokinetic studies determine the success or failure of a drug with emphasis on cost, speed and accuracy.

Over the last few years, Pharmacokinetics has emerged as an integral part of drug development, especially when identifying a drug’s biological properties. PK studies help in determination of drug absorption, distribution and how it gets excreted from the body and what it becomes over this journey. These four processes are usually called as ADME These factors become critical in the case of assessing risk in a new chemical entity often abbreviated as N Pharmacokinetic studies in Boston CEs. The undesired PK characteristics include low bioavailability due to high extraction or poor absorption characteristics, short elimination half-life leading to short duration of action and excessive variability due to genetic or environmental factors. There is a lot of development in tools for the prediction of drug absorption, drug clearance and drug–drug interactions, in addition to the scaling of pharmacokinetic parameters from animals to man. As a result, PK screening is instrumental in selection of lead compounds with the expected bioavailability profiles for taking the drug discovery process further.

This increased consideration of the suitability of the pharmacokinetic profile has led to a reduction in the early termination of programmes due to pharmacokinetic failings. This in turn has highlighted the other causes for compounds being considered unsuitable for drug development. Such reasons include inadequate safety and efficacy. The above said aspects can be partially addressed by correlating it with pharmacodynamics of the drug candidate. Preclinical pharmacodynamics studies and the identification of appropriate safety and efficacy biomarkers provide avenues to increase the confidence in rationale and safety of new drug molecules.

Drawing inferences from the correlation between the Pharacokinetics and Pharmacokinetics is an important tool that is emerging. PK/PD modeling can also help in translating the in vitro compound potency from all the way from in vitro setting to clinical phases. We build the study designs with an assumption to study the relationship between medical exposure and therapeutic activity. Such relationships are usually very complex. So, we have to develop a dynamic preclinical studies model that will provide information to build a mathematical and mechanistically relevant PK/PD models. Based on the data from these models, we can further refine the basic models of study. The ultimate output is a powerful predictive tool based on an in-depth understanding of the requirements for efficacy.

A well designed PK/PD will offer logical approach to understand the mechanism of action of drug and select the most optimal approach. Application of PK/PD modelling in the early discovery can minimise the animal usage and predict the dosage range right from early clinical testing. PK-PD models help in the aggregation of data from various studies and help in deeper understanding of relationship between drug and the disease. As the result of the above said reasons, PK and PD are becoming more and more important in the drug R and D.
