The demonstration that two pharmaceutical products containing the same active ingredient reach the systemic circulation at comparable rate and extent, usually judged by AUC and Cmax within accepted confidence limits.

Related: Bioavailability, Marketing authorisation dossier
Pharmacovigilance

The science of detecting, assessing, understanding and preventing adverse effects or any other medicine-related problems, mainly through spontaneous reporting and periodic safety review after marketing.

Related: Adverse drug reaction (ADR), Yellow card reporting
Yellow card reporting

A spontaneous adverse-drug-reaction reporting system in which health professionals submit a standard form to the national pharmacovigilance centre describing a suspected reaction and the implicated medicine.

Related: Pharmacovigilance, Adverse drug reaction (ADR)
Scheduled drug classification

The legal grouping of medicines by the level of control over sale, such as prescription-only, pharmacy-only or over-the-counter, which determines who may supply them and under what record-keeping conditions.

Related: Prescription requirements, Narcotic and psychotropic control
Prescription requirements

The legal and professional elements a valid prescription must contain, including prescriber details and signature, patient identification, drug name, strength, dosage form, dose, route and duration, without which dispensing is improper.

Related: Scheduled drug classification, Dispensing error
Narcotic and psychotropic control

The special legal regime for medicines with abuse potential, imposing licence requirements, secure storage, prescription limits and mandatory record keeping to prevent diversion and misuse.

Related: Scheduled drug classification, Drug recall
Drug recall

The process of removing a medicine from distribution because of a defect or safety concern, classified by severity from class I for serious harm to class III for minor problems, with defined retrieval and reporting steps.

Related: Pharmacovigilance, Quality control (QC)
Bioavailability

The fraction of an administered dose of unchanged drug that reaches the systemic circulation, and for orally given drugs the rate at which it does so, expressed relative to the intravenous route.

Related: Bioequivalence, First-pass metabolism
First-pass metabolism

Presystemic elimination of a drug in the gut wall or liver before it reaches the systemic circulation after oral dosing, reducing bioavailability and often requiring a higher oral dose.

Related: Bioavailability, Half-life
Half-life

The time taken for the plasma concentration of a drug to fall by half during elimination, used to estimate dosing interval and the time needed to reach steady state.

Related: Volume of distribution, Steady state
Volume of distribution

The apparent volume relating the amount of drug in the body to its plasma concentration, indicating how widely a drug distributes into tissues and guiding loading-dose calculation.

Related: Half-life, Clearance
Clearance

The volume of plasma from which a drug is completely removed per unit time, reflecting the combined activity of hepatic metabolism and renal excretion and determining maintenance dose rate.

Related: Volume of distribution, Half-life
Steady state

The condition during repeated dosing when the amount of drug entering the body equals the amount eliminated, so plasma concentrations fluctuate within a stable range around a mean value.

Related: Half-life, Therapeutic drug monitoring
Therapeutic drug monitoring

Measurement of plasma drug concentrations to individualise dosage for drugs with narrow therapeutic indices, such as digoxin, lithium, phenytoin and aminoglycosides, where clinical response is hard to judge.

Related: Steady state, Narrow therapeutic index
Narrow therapeutic index

A property of drugs whose effective and toxic concentrations lie close together, so small changes in dose or blood level can cause treatment failure or serious toxicity.

Related: Therapeutic drug monitoring, Adverse drug reaction (ADR)
Adverse drug reaction (ADR)

A harmful or unintended response to a medicine occurring at doses normally used for prophylaxis, diagnosis or treatment, excluding therapeutic failure and overdose.

Related: Pharmacovigilance, Drug interaction
Drug interaction

A change in the effect of one medicine caused by another medicine, food or substance, acting through pharmacokinetic mechanisms such as enzyme induction or inhibition, or pharmacodynamic mechanisms at the same target.

Related: Adverse drug reaction (ADR), Cytochrome P450 inhibition
Cytochrome P450 inhibition

Blocking of hepatic metabolising enzymes by a drug, slowing the breakdown of co-administered substrates and raising their plasma levels, as seen with macrolides, azoles and ritonavir.

Related: Drug interaction, First-pass metabolism
Receptor agonist

A drug that binds a receptor and activates it to produce a biological response, having both affinity and intrinsic activity, in contrast to a blocker at the same site.

Related: Receptor antagonist, Partial agonist
Receptor antagonist

A drug that binds a receptor with affinity but no intrinsic activity, preventing the natural ligand or an agonist from producing a response; it may be competitive or non-competitive.

Related: Receptor agonist, Partial agonist
Partial agonist

A ligand that binds a receptor and produces a submaximal response even at full occupancy, so it can act as an agonist or blunt the effect of a full agonist depending on context.

Related: Receptor agonist, Receptor antagonist
Therapeutic index

The ratio of the dose producing toxicity to the dose producing the desired effect in a population, a large value indicating a wide margin of safety.

Related: Narrow therapeutic index, Therapeutic drug monitoring
Patient counselling

The structured conversation in which a pharmacist explains how to take a medicine, expected effects, precautions and what to do about missed doses, checking the patient's understanding afterwards.

Related: Good pharmacy practice (GPP), Medication adherence
Medication adherence
