Drugs utilization profile in England and Wales in the past 15 years: a secular trend analysis.

BACKGROUND: Medication use assessment has a critical role in promoting the effective and rational use of pharmaceutical medications. There are no studies that have explored the utilization of all medications in England and Wales in the past 15 years without restrictions in the age group being studied or class of medications. AIM: To explore the medication utilization pattern of dispensed medications in England and Wales in the past 15 years. METHOD: A secular trend analysis study using publically available dispensing data on the population level in England and Wales for the duration between 2004 and 2019. Medication dispensing data was extracted from the Prescription Cost Analysis database. RESULTS: Medication prescriptions rate increased by 42.6% [from 1,345,095.75 (95% CI 1,345,004.25 - 1,345,187.26) in 2004 to 1,918,138.48 (95% CI 1,918,038.38 - 1,918,238.57) in 2019 per 100,000 persons, trend test, p < 0.001]. During the study period, the most common medication prescriptions were for the cardiovascular system, central nervous system, and endocrine system, which accounted for 30.2%, 18.8%, and 9.4%, respectively. The rate of medication prescriptions for skin, immunological products and vaccines, infections, and musculoskeletal and joint diseases decreased by 18.4%, 15.8%, 9.8%, and 5.7%, respectively. CONCLUSION: The last two decades have witnessed a remarkable rise in the quantity of medications dispensed in community settings. Utilization of chronic disease medications has increased in the past 15 years, specifically, dispensed medications for the cardiovascular system, central nervous system, and endocrine system. It is necessary to conduct additional cohort studies to investigate the clinical outcomes and prescribing safety of these medications.

Efficacy and Best Mode of Delivery for Tranexamic Acid in Post-Inflammatory Hyperpigmentation: A Systematic Review.

Background: Post-inflammatory hyperpigmentation (PIH) is skin hyperpigmentation that occurs due to any inflammatory condition. Triggering the melanocytes by inflammation leads to melanin overproduction and deposition. Tranexamic acid (TXA) is an antifibrinolytic medication prescribed to treat bleeding. Recently, there are some studies about the use of TXA in the treatment of PIH. Objective: The aim of this study is to identify the efficacy and the best mode of delivery for tranexamic acid in the treatment of PIH. Methods: This systematic review is reported in accordance with PRISMA guidance. We included all relevant English-language studies that were published up to September 2022 in the following electronic databases: Cochrane Library, PubMed, Embase, and Google Scholar. The initial search yielded 61 articles, 9 of which were included after applying inclusion and exclusion criteria. Results: The systematic review included a total of 196 patients who were over the age of 16 years old. Tranexamic acid was delivered orally in 4 studies, topically in 2 studies, and both simultaneously in 1 study. In addition, intradermal injection was used in 2 other studies. Almost all studies advocated the use of all routes for accelerating the clearance of hyperpigmentation with more favor towards topical and intradermal routes due to their mild reported side effects when compared to oral routes. Conclusion: Intradermal TXA is considered the best route, which exhibits fewer side effects with less cost and excellent outcomes, while oral TXA is found to be less preferable than other routes due to the incidence of undesirable adverse events.

Guillain-Barré Syndrome in an Elderly Patient as a Complication of COVID-19 Infection.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is an infection that mainly affects the respiratory system. It may present with fever, fatigue, dry cough, and dyspnea. In addition, numerous studies and case reports discussed those viruses showing their effects on the nervous system. In this report, we present a case of a 66-year-old Saudi man who had been recovering from symptoms related to coronavirus 2019 (COVID-19) associated disease. He was presented with sudden progressive ascending weakness that started in the left leg, and it spread to involve both legs and then both arms, five days prior to hospitalization. Lumbar puncture and nerve conduction studies showed that the patient has an acute motor-sensory axonal neuropathy (AMSAN) variant of Guillain-Barré syndrome (GBS). The patient was treated with intravenous immunoglobulin (IVIG) and supportive care. The patient was discharged after 15 days of hospitalization with clinical improvement. In conclusion, to our knowledge, this study investigated the first reported case of GBS in an elderly patient as a complication of COVID-19 infection in Saudi Arabia, with the most severe variant AMSAN. As the COVID-19 pandemic continues, clinicians should consider GBS as a neurological complication of COVID-19, and therapy must be initiated. Further studies are needed to study the possible mechanism of GBS in patients with COVID-19 in the future.
