Medication use among older Australians seeking alcohol and other drug treatment.

OBJECTIVE: To describe the use of medications that interact with alcohol or for which alcohol reduces the medication's efficacy in older adults consuming alcohol at hazardous levels. METHOD: Retrospective file audit of patients discharged from Australia's only older adult-specific alcohol and other drug treatment service. RESULTS: Seventy-two patients aged between 58 years and 87 years (M = 65.88; SD = 5.67) drinking alcohol at hazardous or harmful levels were taking between 1 and 12 pharmaceutical drugs (M = 4.03; SD = 2.42). The majority (92%) of patients were taking at least one medication that placed them at high risk of serious adverse side effects when consumed with alcohol. The efficacy of most patients' (97%) medication was deemed to be significantly reduced when consumed with alcohol. CONCLUSIONS: Among older adults who consume alcohol at hazardous levels, many take prescribed medications that adversely interact with alcohol or have reduced efficacy when consumed alongside alcohol. Targeted education is required for patients and health-care workers to mitigate these risks.

An analysis of three dimensional diffusion in a representative arterial wall mass transport model.

The development and use of drug eluting stents has brought about significant improvements in reducing in-stent restenosis, however, their long term presence in the artery is still under examination due to restenosis reoccurring. Current studies focus mainly on stent design, coatings and deployment techniques but few studies address the issue of the physics of three dimensional mass transport in the artery wall. There is a dearth of adequate validated numerical mass transport models that simulate the physics of diffusion dominated drug transport in the artery wall whilst under compression. A novel experimental setup used in a previous study was adapted and an expansion of that research was carried out to validate the physics of three dimensional diffusive mass transport into a compressed porous media. This study developed a more sensitive method for measuring the concentration of the species of interest. It revalidated mass transport in the radial direction and presented results which highlight the need for an evaluation of the governing equation for transient diffusive mass transport in a porous media, in its current form, to be carried out.
