A Comprehensive Guide to Therapeutic Drug Monitoring (TDM)_updated

2. A Comprehensive Guide to Therapeutic Drug Monitoring (TDM) Therapeutic treatment has been used worldwide to cure various diseases, alleviate pain in specific body parts and even recover from injury. Pyxuspharmaceuticalshas Many essential tools that are used in therapeutic treatments, such as radiation therapy, drug therapy, nutrition therapy, psychiatry, surgery, medical devices, & stem-cell therapies. Therapeutic treatment is renowned across the globe for curing a wide range of therapeutic areas, such as Migraine, Respiratory, Headache, Neurodegenerative Conditions, Oncology, and Movement Disorders. The demand for therapeutic treatment is rising rapidly worldwide. However, therapeutic drug monitoring (TDM) must be done if you are taking therapeutic treatment. In this blog, we will walk you through what therapeutic drug monitoring (TDM) is, its uses, its importance, guidelines, and vital factors.

3. What is Therapeutic Drug Monitoring (TDM)? Therapeutic Drug Monitoring is a test for measuring the concentration of a drug in a patient’s bloodstream. It is done to ensure that the concentration of medicine that the patient is consuming is safe & effective and not causing any dangerous side effects. TDM helps healthcare providers ensure that patients are consuming the correct dosage of the prescribed drug. The drug concentration is measured in blood and body fluids like urine, sweat, and saliva. TDM helps monitor individual drug concentration and help doctors give effective & quick diagnosis to patients. The drug metabolism varies from patient to patient. And TDM helps in individualizing the required dosage in specific cases, thereby improving the clinical effects of the drug & enhancing patient management.

4. Importance & Need of Therapeutic Drug Monitoring As mentioned above, Therapeutic drug monitoring (TDM) helps individualize patient-specific dosage regimens (drug therapy). It also helps enhance the drug’s consumption efficacy and reduces the toxicity of drugs for diagnostic purposes. Some drugs have a wide co-efficient of pharmacokinetic variation, which will have a significant intra-patient variation between drug dosage & its effect. TDM is very beneficial & helpful in these situations. TDM helps healthcare providers determine the correct dosage for their patients. Once the determined dosage is prescribed, the patient is tested regularly to ensure the effectiveness of the drug concentration. Note: Side effects vary from patient to patient, and TDM helps doctors give the proper medication to the patients.

5. Essential Information required for Therapeutic Drug Monitoring • Drug Pharmacokinetics • Administration of the Drug dosage • Clinical Condition of the patient • Clinical History of the patient concerning past Therapeutic treatments • Clinical Responses of the patient • Sampling time • The primary purpose of the TDM for determining efficacy and toxicity for diagnosis

6. Process of Therapeutic Drug Monitoring • The following is the process of TDM: • Administration of a pre-determined dose of a drug • Collection & Analysis of blood samples • Pharmacokinetic Assessment of responses • Evaluation of Clinical response • Finalizing Dosage Regimen

7. Guidelines for Therapeutic Drug Monitoring (TDM) • Various organizations have laid down guidelines for TDM for different drug categories. Based on these specific drug guidelines and other sources, the following stages are critical for conducting & interpreting Therapeutic Drug Monitoring (TDM) studies: • Documentation & Legal Procedures involved in TDM • Sample Collection Procedure • Tests need to be conducted before conducting TDM • Sample collection timing is decided depending on the half-life of the drug • Sample concentrations • Storage & shipment of samples • Monitoring of patients • Laboratory measurements of drug concentration in blood • Necessary action is required if abnormal results are observed • Computing analytical data • Interpretation of results & recommendations accordingly

8. Factors affecting Therapeutic Drug Monitoring (TDM) • Testing Methodology • Sample collection time & type • Dosage Regimen • Formation of active metabolites • Age Effect • Pharmacokinetics • Pharmacodynamics

9. Limitations of Therapeutic Drug Monitoring (TDM) • Limited Infrastructure facilities in rural areas • Variations in reports from lab to lab • Cost of Therapeutic Drug Monitoring (TDM) study • Lack of training & quality assurance skills • Invalid or Insufficient data for suggesting the target concentration range • Variation or Lack of Accuracy & Sensitivity of drug assay methods • Active metabolites of a drug may contribute to therapeutic effect, but the active metabolites cannot be measured • A limited number of drugs are suitable for TDM

10. Analytical Techniques used to assay drugs in blood • Many analytical techniques are used for quantifying the amount of drugs in blood or any other body fluid. The methods should be: • Able to detect small amounts • Simple & Straightforward to use • Able to differentiate between compounds of similar structure – drug & its active metabolites • Not having any interference with other drugs which are administered simultaneously. • The following analytical techniques are used to assay drugs in blood and other body fluid: • Enzyme Immune Assay (EIA) • RadioImmuno Assay (RIA) • Spectrophotometry • Chromatography
