Prescripción de la teofilina, concentraciones séricas y toxicidad
Lancet (London, England)
|September 10, 1983
Resumen
Los ensayos de teofilina sérica son cruciales para el manejo de pacientes con teofilina de liberación lenta. Los niveles altos indican toxicidad, a menudo vinculada a problemas hepáticos o prescripciones duplicadas, lo que requiere ajustes de dosis.
Área de la Ciencia:
- Farmacología Farmacología.
- La medicina clínica es la medicina clínica.
- Monitoreo de las drogas.
Sus antecedentes:
- El uso creciente de la teofilina de liberación lenta requiere un monitoreo regular.
- Los ensayos de teofilina sérica se solicitan con frecuencia, lo que indica la necesidad de evaluar su impacto clínico.
Objetivo del estudio:
- Evaluar la influencia de los ensayos de teofilina sérica en el manejo del paciente.
- Identificar los factores asociados con altos niveles séricos de teofilina y evaluar los resultados clínicos.
Principales métodos:
- Análisis retrospectivo de 1913 ensayos de teofilina sérica durante más de 18 meses.
- Se analizaron dos grupos de pacientes: pacientes ambulatorios estables y aquellos con niveles > 25 mg/l.
Principales resultados:
- Correlación suelta entre la dosis y el nivel sérico en pacientes estables.
- Los niveles altos están relacionados con la función hepática anormal, el uso de diuréticos y la prescripción duplicada.
- La reducción de la dosis se produjo cuando los niveles eran altos, pero los aumentos fueron infrecuentes para los niveles bajos.
Conclusiones:
- La toxicidad no sospechosa de la teofilina contribuye a una morbilidad significativa.
- El seguimiento minucioso y la interpretación del ensayo son vitales para una terapia segura y efectiva con teofilina.

Antiasthma Drugs: Methylxanthines
Theophylline, a member of the methylxanthine class of bronchodilators, has long been used in asthma management. While its exact mechanism of action is not fully understood, it is believed to have multiple effects on various cellular processes.
Theophylline is thought to inhibit phosphodiesterase enzymes, increasing intracellular levels of cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP). This rise in cAMP and cGMP concentrations stimulates cardiac function,...

IV Infusion to Oral Dosing: Conversion Methods
The development of extended-release formulations has facilitated the transition from intravenous to oral medication, offering a more convenient and patient-friendly approach to drug administration. This transition, however, requires careful management to ensure that therapeutic drug levels are maintained, preserving efficacy and avoiding adverse effects. Understanding pharmacokinetic principles and dosage calculations is critical during this process.Pharmacokinetics of the...
Therapeutic Drug Monitoring: Drug Analysis Methods
Therapeutic Drug Monitoring (TDM) is a clinical practice that measures specific drug levels in a patient's blood or body tissues to tailor drug therapy effectively. This monitoring is critical for managing drugs with narrow therapeutic indices like digoxin and phenytoin, ensuring they are both safe and effective. For instance, monitoring theophylline levels in asthma patients involves precision and sensitivity to adjust doses according to individual responses to therapy, ensuring efficacy and...
Drug Toxicity: Dose-Dependent Reactions
Drug toxicities can be stratified into pharmacological, pathological, or genotoxic based on their mechanisms. The incidence and severity of these toxicities generally increase with the drug's concentration in the body and exposure time.Pharmacological toxicity is evident when the therapeutic effects of drugs overshoot into adverse reactions in a predictable, dose-dependent manner. Central nervous system (CNS) depression from barbiturates is a classic example, with effects escalating from...
Drug toxicity: Drug–Drug Interaction
Drug–drug interactions can precipitate toxicity through multiple mechanisms. Absorption interactions alter how drugs enter the body, exemplified when ranitidine increases the absorption of basic drugs, while cholestyramine decreases the levels of propranolol. Protein binding interactions occur when drugs share the same binding sites on plasma proteins. Drugs like aspirin and warfarin, when bound in excess, can lead to increased free drug concentrations, enhancing the potential for...
Toxicokinetics: Overview
Studies that assess how a drug is absorbed, distributed, metabolized, and excreted (ADME) at toxic doses are termed toxicokinetics. Understanding toxicokinetics helps predict adverse drug reactions (ADRs) and manage toxicity in humans.Toxicokinetics differs from pharmacokinetics mainly in the dose levels studied, with toxicokinetics focusing on higher toxic doses. The kinetics at these levels can be non-linear due to altered physiological processes. Toxicodynamics examines the relationship...
