With training in pharmacology, a pharmacologist has an expert knowledge as well as working experience in the subjects of therapeutics, pharmacokinetics, and toxicology along with exposure to subjects such as forensic medicine during the medical education. All these knowledge domains can be applied and act as an interface to the forensic situations. The skills and expertise of a forensic pharmacologist can be useful in a large and diverse number of legal cases. With an ever increasing incidence of criminal and civil cases in India, the development and inclusion of forensic pharmacologist in the judicial system of India are the need of the hour. The research in pharmacology has witnessed great technological advancement that allows it to expand its scope beyond the domain of therapeutics, thus enabling Indian pharmacologists to explore the niche area of Forensic Pharmacology. Differing pharmacokinetics and pharmacodynamics of drugs in living and dead, drug interactions, abuse of drugs, personal injury or death due to drug exposure leading to medico-legal issues, environmental exposure to chemicals, and doping and forensic pharmacovigilance are the diverse aspects of Forensic Pharmacology. © 2016 Journal of Pharmacy And Bioallied Sciences | Published by Wolters Kluwer - Medknow 83.

Why is forensic toxicology important?
It is considered a hybrid of analytical chemistry and fundamental toxicology with medicolegal applications. It enables analyses of biological tissues and fluids for the presence of poisons and drugs by determining their concentration and interpretation of obtained findings. Forensic toxicology studies are mostly analytical in nature because the estimation of actions and effects of drugs and toxic substances requires their qualitative and quantitative determinations. The interpretation of forensic toxicological results demands knowledge of many different aspects of analytical toxicology as well as pharmacokinetics and pharmacodynamics. These results are of great importance as they may answer the question about the role of drugs and causative agents in a person's illness, behavior, or circumstances of death. Forensic toxicology can be divided into the following subcategories: clinical toxicology, postmortem forensic toxicology, human performance toxicology, and forensic drug testing. Toxicology studies are useful and necessary for the final decision regarding, among others, the cause and manner of death, driving under the influence of drugs and alcohol, an inability to perform in the workplace (behavioral toxicology), and drug abuse testing. Toxicological investigations have an impact on the knowledge of case history, specimen selection, choice of extraction procedure and analytical techniques, and proper interpretation of obtained data.

What is toxicology laboratory?
The forensic toxicology laboratory exists for the sole purpose of providing interpretable analytical data. Therefore, the analytical strategy is designed with anticipation of the need for later interpretation. The most appropriate specimens should be analyzed by sensitive, specific, and quantitatively accurate and precise techniques to yield reliable data upon which to base opinions. The toxicologist must be absolutely certain that the analytical data are accurate. Furthermore, the samples must be properly preserved and clearly traceable to the subject of the investigation by an unbroken chain of custody, and handled and stored with a level of security sufficient to preclude tampering.

What is the study of a drug's molecular, biochemical, and physiologic effects or actions?
Pharmacodynamics is the study of a drug's molecular, biochemical, and physiologic effects or actions. It comes from the Greek words "pharmakon" meaning "drug" and "dynamikos" meaning "power." All drugs produce their effects by interacting with biological structures or targets at the molecular level to induce a change in how the target molecule functions in regards to subsequent intermolecular interactions. These interactions include receptor binding, post-receptor effects, and chemical interactions. Examples of these types of interactions include (1) drugs binding to an active site of an enzyme, (2) drugs that interact with cell surface signaling proteins to disrupt downstream signaling, and (3) drugs that act by binding molecules like tumor necrosis factor (TNF).[1] Subsequent to the drug-target interaction occurring downstream, effects are elicited which can be measured by biochemical or clinical means. Examples of this include the (1) inhibition of platelet aggregation after administering aspirin, (2) the reduction of blood pressure after ACE inhibitors, and (3) the blood-glucose-lowering effect of insulin. [2][3][2]While these examples seem obvious, the administration of the preceding drug examples should be kept in mind so practitioners do not administer these drugs to inhibit platelet aggregation, lower blood pressure or lower blood glucose but to reduce the risks of cerebrovascular accident, myocardial infarction, and renal and eye complications through the drug's pharmacodynamic effects. [4]
What is indirect pharmacodynamics?
Effect compartment and indirect pharmacodynamics: A delay between the appearance of drug in the plasma and its intended effect may be due to multiple factors to include transfer into the tissue or cell compartment in the body or a requirement for the inhibition or stimulation of a signal to be cascaded through intracellular pathways. These effects can be described by either using an effect compartment or using indirect pharmacodynamic response models, which describe the effect of the drug through indirect mechanisms such as inhibition or stimulation of the production or elimination of endogenous cellular components that control the effect pathway. [11]
How do drugs produce their effects?
Drugs produce their effects by interacting with biologic targets, but the time course of the pharmacodynamic effect is dependent on the mechanism and biochemical pathway of the target. Effects can be classified as direct or indirect and immediate or delayed. Direct effects are usually the result of drugs interacting with a receptor or enzyme that is central to the pathway of the effect. Beta-blockers inhibit receptors that directly modulate cAMP levels in smooth muscle cells in the vasculature. Indirect effects are the result of drugs interacting with receptors, proteins of other biologic structures that significantly upstream from the end biochemical process that produces the drug effect. Corticosteroids bind to nuclear transcription factors in the cell cytosol which translocate to the nucleus and inhibit transcription of DNA to mRNA encoding for several inflammatory proteins.[6] Immediate effects are usually secondary to direct drug effects. Neuromuscular blocking agents such as succinylcholine, which consists of two acetylcholine (ACh) molecules linked end to end by their acetyl groups, interact with the nicotinic acetylcholine receptor (nAChR) on skeletal muscle cells and leave the channel in an open state, resulting in membrane depolarization and generation of an action potential, muscle contraction and then paralysis within 60 seconds after administration.[7] Delayed effects can be secondary to direct drug effects. Chemotherapy agents that interfere with DNA synthesis, like cytosine arabinoside which is used in acute myeloid leukemia, produce bone marrow suppression that occurs several days after administration.
What is the slope of the relationship between drug concentration and drug effect?
Hill coefficient is the slope of the relationship between drug concentration and drug effect. Hill coefficients above 2 indicate a steep relationship (i.e., small changes in concentration produce large changes in effect), and hill coeffici ents above 3 indicate an almost instantaneous "all or none" effect. [5]
How does chronic exposure to an antagonist affect receptors?
Receptor Up- and Downregulation: Chronic exposure of a receptor to an antagonist typically leads to upregulation, or an increased number of receptors, while chronic exposure of a receptor to an agonist causes downregulation or a decreased number of receptors . [9]Other mechanisms involving alteration of downstream receptor signaling may also be involved in up- or downmodulation without altering the receptor number on the cell membrane. [10]The insulin receptor undergoes downregulation to chronic exposure to insulin. The number of surface receptors for insulin is gradually reduced by receptor internalization and degradation brought about by increased hormonal binding. An exception to the rule is the receptor for nicotine that demonstrates upregulation in receptor numbers upon extended exposure to nicotine, despite nicotine being an agonist, which explains some of its addictive properties.
