The global therapeutic drug monitoring market is growing significantly due to the rising cases of chronic diseases and the escalating demand for personalized medicine. Therapeutic Drug Monitoring (TDM) describes the application of clinical treatments involving the quantification of the drugging levels of a certain drug in the circulation of a patient at specific intervals to achieve the optimum patient doses.

The market growth is being driven by improvements in analytical technologies and incorporation of TDM into the wider healthcare systems.

Therapeutic Drug Monitoring Market Driver

Increase in the Rate of Chronic Illnesses to Expand the Market

The market is expanding because of the rising burden of chronic diseases in the world, which is a major trigger towards the therapeutic drug monitoring market. Therapeutic conditions like cardiovascular diseases, diabetes, cancer, autoimmune diseases, and neurological diseases are likely to require prolonged medication schedules, and many of them require drugs whose therapeutic windows are narrow.

Innovations Related to Analytical Technologies to Advance the Market

There is a tremendous growth of technologies related to analysis, which is greatly affecting and increasing the therapeutic drug monitoring market. Incorporation of very sensitive and precise methods such as liquid chromatography-mass spectrometry (LC-MS/MS) and enhanced immunoassays has transformed the phenomenon of accurate quantitation of the drugs even at extremely low levels and in a complex biological substance.

Therapeutic Drug Monitoring Market Restraint

Expensive Implementation and Operation CoststoPose Potential Impediments on this Market

One major limiting factor that can be said to affect the therapeutic drug monitoring market is the high cost of both integrating the TDM services and operating it, more so when it involves smaller individual hospitals and healthcare centers, especially in the developing economies. In addition to investment, incurred operational costs include reagents, consumable costs, maintenance of these instruments, and annual calibration of the high-tech instruments.

Therapeutic Drug Monitoring Market Opportunity

Movement into Emerging Markets to Create Opportunity in this Market

There is also a high growth opportunity that is presented by the extending of therapeutic drug monitoring (TDM) activities to emerging markets. There is a fast-growing economy in the countries present in regions such as Asia-Pacific, Latin America, and Africa; these countries are also reporting an improvement in the healthcare infrastructure and the eventual increase in healthcare spending.

Segmentation

Key Insights

The report covers the following key insights:

• Market drivers, restraints and opportunities
• Influence of key industrial players and key developments
• Demand for personalized medicine
• Advancements in analytical technologies

Analysis by Type

By Type, the Therapeutic Drug Monitoring market is divided into Instruments (Immunoassay Analyzers, Clinical Chemistry Analyzers & Others), Consumables & Reagents & Software

The part of the market will grow into the instruments area because of constant technological improvement in accuracy, sensitivity and throughput of the measurements of the concentrations of drugs.

The growth of the "Consumables & Reagents" segment is directly connected with the growing number of TDM tests that are currently conducted worldwide.

Analysis by Technology

Based on Technology, the market is divided into Immunoassays, Chromatography & Others

The immunoassays are considered a cornerstone of TDM, as they are readily available, their costs are rather low relative to the results obtained in a rather short period of time, and, therefore, they are very well suited to be used in hospitals and testing laboratories on a routine basis.

The development of a chromatography segment is driven by the continuous development of mass spectrometry, which offered huge gains in detection limits and reduced the analysis times.

Analysis by Application

Based on Application, the market is divided into Oncology, Cardiology, Neurology, Infectious Diseases & Others

The TDM market oncology application segment has been rising at a high rate with growing complexity in cancer treatments and focused choice of individual approach to medications and treatment.

The cardiology segment is the other key factor in the market growth of TDM because of the high disease burden of cardiovascular diseases (CVDs) worldwide and the urgent need for accurate cardiac drug management strategies.

Analysis by Drug Class

Based on Drug Class, the market is divided into Antiepileptic Drugs, Antiarrhythic Drugs, Antibiotic Drugs & Others

Antiepileptic Drugs (AEDs) almost constitute a third of market growth of TDM since epilepsy and other seizure disorders are by nature complex to control.

To the extent that TDM allows clinicians to optimise doses, TDM in the antiarrhythmic drugs segment contributes greatly to patient safety and the long-term patient management of complex cardiac disorders, thereby ensuring the growth of the TDM market on a consistent basis.

Analysis by Sample Type

Based on Sample Type, the market is divided into Blood, Urine & Others

Serum or plasma (blood) is still considered the gold standard sample type for therapeutic drug monitoring, meaning that they provide a direct insight into systemic drug concentrations.

Although not necessarily delivering real-time drug concentration to adjust the dose because of patient compliance and poor drug response that can be evaluated in the TDM market, urine specimens are increasingly being used, especially when measuring long-term drug exposure and drug metabolites.

Analysis by End User

Based on End User, the market is divided into Hospitals, Diagnostic Imaging Centers & Others

The biggest persistence in the TDM market, which has dominated the market growth, is the hospitals, which have extensive healthcare provisions for their customers and require what is needful: instant and futile monitoring of the patients.

Although the main business activity of diagnostic imaging centres is the provision of imaging services, they help increase the TDM market by expanding their involvement in outpatient diagnostics and specific testing, usually coordinating their efforts with referring physicians.

Regional Analysis

To gain extensive insights into the market, Download for Customization

Based on region, the Therapeutic Drug Monitoring market has been studied across North America, Europe, Asia Pacific, Latin America, and the Middle East & Africa.

North America and especially the US enjoy a central role in the world TDM market. The power of this region is due to the well-established healthcare system, significant degree of spending on healthcare, and strong focus on individual care. The exceptionally high rate of incidence of chronic conditions such as cancer, cardiovascular diseases, and neurological diseases, which need prolonged medication with a narrow therapeutic range, is a driving force behind a never-ending demand for TDM.

• According to U.S. Centers for Disease Control and Prevention, 13500000 therapeutic drug monitoring tests are conducted annually in U.S.
• According to U.S. Centers for Medicare & Medicaid Services, 4600 CLIA-certified labs are offering TDM services in U.S.

Europe is a large and expanding territory served by TDM, driven by developed healthcare systems, a comprehensive regulatory landscape, and the ageing population group. Just like North America, Europe is experiencing an increasing burden of chronic diseases, a factor that necessitates the streamlining of drug therapy. In European nations, the governments tend to support the concept of public healthcare, and even in times when the funding is limited, they still understand the significance of TDM regarding enhancing patient safety and treatment efficacy.

Asia-Pacific is also becoming the largest growing market for TDM that is characterised by its fast-developing healthcare system, increased healthcare spending, and high and ageing population. Several countries, such as China, India, and Japan, are experiencing epidemics of chronic diseases, an aspect that necessitates much demand on drug management. Lately increasing awareness about personalised medicine as well as the advantages of TDM in making treatment more effective and safer points to an enhancement in the geographical region.
