Prescribing habits for theophylline preparations
Journal of the Royal Society of Medicine
|November 1, 1983
Summary
This study found that slow-release theophylline preparations were commonly prescribed for 135 patients. However, most patients received low doses, and serum drug level monitoring was rarely performed.
Area of Science:
- Pharmacology
- Clinical Pharmacy
- Respiratory Medicine
Background:
- Theophylline is a bronchodilator used for respiratory diseases.
- Optimizing theophylline therapy involves appropriate dosing and monitoring.
- Understanding current prescribing patterns is crucial for quality improvement.
Purpose of the Study:
- To analyze theophylline prescription patterns in a mixed inpatient and outpatient population.
- To evaluate the utilization of slow-release formulations.
- To assess the frequency of serum theophylline level monitoring.
Main Methods:
- Retrospective review of medical records.
- Inclusion of 80 inpatients and 55 outpatients prescribed theophylline.
- Data collection on drug formulation, dosage, and monitoring practices.
Main Results:
- Slow-release theophylline preparations were the predominant formulation used.
- The majority of patients were prescribed low daily doses of theophylline.
- Serum theophylline level monitoring was infrequently conducted across the patient cohort.
Conclusions:
- While slow-release theophylline is preferred, low-dose prescribing suggests potential under-treatment.
- The lack of routine serum drug level monitoring may compromise therapeutic efficacy and safety.
- Further investigation into optimal theophylline dosing and monitoring strategies is warranted.
