NSWPIC received 1158 reports of intentional pregabalin poisonings, with a 53.8% increase per year, 2005–2016 (95% CI = 44.0–64.2%, P < 0.001). We identified 88 pregabalin‐associated deaths, 57.8% yearly increase (95% CI = 30.0–91.6%, P < 0.001). Patients overdosing on pregabalin commonly co‐ingested opioids, benzodiazepines and illicit drugs, and had high rates of psychiatric and substance use comorbidities; 14.7% of pregabalin users were classed by the LCA as at high risk of misuse, and were more likely to be younger, male, co‐prescribed benzodiazepines or opioids, have more individual prescribers and higher pregabalin strengths dispensed. Conclusions: There has been a dramatic increase in pregabalin use, poisonings and deaths in Australia since it became subsidized publicly in 2013. One in seven Australians dispensed pregabalin appears to be at high risk of misuse.]]> Tue 14 Mar 2023 14:48:47 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:40438 14 years who took an overdose of dihydropyridines (amlodipine, felodipine, lercanidipine, nifedipine) were included. Concurrent overdoses with non-dihydropyridine CCBs, alpha-blockers and beta-blockers were excluded. Patient demographics, drugs exposure details, serial vital signs, treatments and outcome were collected. Results: There were 100 patients. 68 took mixed overdoses of dihydropyridines with ARBs/ACEIs and 32 took single overdoses of dihydropyridines without ARBs/ACEIs. The mixed group had lower median nadir mean arterial pressures (62 vs 75 mmHg, p < 0.001), more frequently had hypotension (OR 4.5, 95%CI: 1.7–11.9) or bradycardia (OR 8.8, 95%CI: 1.1–70). Multivariable analysis indicated the mixed overdoses had an 11.5 mmHg (95%CI: 4.9–18.1) lower minimum systolic blood pressure (SBP) compared with the single group; other factors associated with a lower minimum SBP were higher doses [2.3 mmHg (95%CI: 1.1–3.5) lower per 10 defined daily doses] and younger age [2.2 mmHg (95%CI: 0.3–4.2) higher per decade]. A larger proportion of the mixed ingestion group received intravenous fluids (OR 5.7, 95%CI: 1.8–18.6) and antidotes and/or vasopressors (OR 2.9, 95%CI: 1.004–8.6). Conclusion: Combined overdoses of dihydropyridines with ARBs/ACEIs caused more significant hypotension and required more haemodynamic support than overdoses of dihydropyridines alone.]]> Tue 02 Aug 2022 11:11:57 AEST ]]>
