Mar 06,  · INTRODUCTION. Therapeutic drug monitoring (TDM) is generally defined as the clinical laboratory measurement of a chemical parameter that, with appropriate medical interpretation, will directly influence drug prescribing procedures [].Otherwise, TDM refers to the individualization of drug dosage by maintaining plasma or blood drug concentrations within a . Digoxin has a narrow therapeutic margin and potentially life-threatening cardiac adverse effects. Gastrointestinal disorders, neuropsychological disorders and bradycardia are warning signs. Some drug combinations can aggravate the cardiac adverse effects of digoxin, or reduce its efficacy. We review . The ECG features of digoxin effect are seen with therapeutic doses of digoxin and are due to: Shortening of the atrial and ventricular refractory periods — producing a short QT interval with secondary repolarisation abnormalities affecting the ST segments, T waves and U waves.

If the dosage regimen must be altered for any what is the therapeutic effect of digoxin at a later stage of treatment, for example, in patients with renal failure, therapeuttic plasma concentrations again may be helpful. This leads to increased contractility the force of contraction of the heart without increasing heart energy expenditure. World Health Organization. Clin Chem.

Cookies Policy. Plasma potassium levels also need to be closely controlled see side effects, below. This is usually not possible in routine monitoring, which limits the usefulness of plasma concentration measurements of, for example, procainamide, which is metabolized to N-acetylprocainamide acecainidewhich has equipotent antiarrhythmic activity. The process of TDM is predicated on the assumption that therapeutix is a definable relationship between dose and plasma or blood drug concentration, and between concentration https://digitales.com.au/blog/wp-content/review/bloodpressure/what-is-adalat-xl-30mg-used-for.php therapeutic effects.
