Drug utilization review of tramadol hydrochloride in a regional hospital in South Africa; findings and implications

Bridging Old and New in Pain Medicine: An Historical Review

Pain is both one of the oldest complaints known to medicine and a field for some of medicine's latest breakthroughs and innovations. Pharmacologic treatment of pain is one of the oldest remedies, and opioids have been used since ancient times as an effective pain reliever but with certain specific risks for abuse. Greater knowledge of opioids led to a more thorough understanding of the complexities of pain, which may have any number of mechanisms. A greater understanding of nerve fibers and pain signaling led to the development of more drugs and the more targeted delivery of analgesics using the hollow needle. The hollow needle changed pain treatment and led to percutaneous injections and what would later become interventional pain medicine with regional anesthesia and nerve blocks. Today, imaging can be combined with interventional techniques for more precise localization of nerves for diagnosis and treatment. The role of artificial intelligence in interventional pain medicine, especially in imaging for interventional procedures, remains unknown but will likely become extremely beneficial.

Review of the Current Situation of Postoperative Pain and Causes of Inadequate Pain Management in Africa

Postoperative pain is one of the most prevalent complications following surgery, and more than 47% of surgical patients endure postoperative discomfort worldwide. In Africa, due to resource shortages and other issues, postoperative pain is substantially more common when compared to developed countries. Severe postoperative pain has many negative effects, including possibly death, which can burden both individuals and society as a whole. Therefore, effectively controlling postoperative pain is becoming increasingly important. To enhance the effectiveness of future pain management, a thorough analysis of the current reasons for inadequate postoperative pain management is necessary. In this article, the present situations of occurring postoperative pain, children's postoperative pain, and pain management in Africa are reviewed, based on relevant and recent literature. In particular, the reasons for inadequate postoperative pain management in Africa are detailed in this article from five perspectives: the inadequate assessment of postoperative pain, the knowledge gap among medical professionals, the patients' misconceptions, the scarcity of resources, and the lack of medications. Additionally, we offer appropriate solutions following various factors.

Factors Associated with Tramadol Abuse: A Cross-Sectional Study Among Commercial Drivers and Assistants in the Accra Metropolitan Area of Ghana

BACKGROUND

There is increasing public health concern regarding the addiction and dependence potential of tramadol.

OBJECTIVE

This study sought to determine factors associated with tramadol abuse among commercial drivers and assistants in the Accra Metropolitan Area of Ghana.

PATIENTS AND METHODS

The study employed a mixed-method quantitative and qualitative approach. It involved a cross-sectional survey and focus group discussions with commercial drivers and assistants at selected transport terminals in Accra. Data on abuse, reasons for abuse, sources of supply, and factors associated with abuse were collected from the respondents and analyzed using STATA and Nvivo, as appropriate.

RESULTS

Of the 458 study participants, 114 (24.9%) indicated that they abused tramadol. The mean (± standard deviation) age of those who abused tramadol (25.14 ± 5.87 years) was significantly lower than that of nonabusers (28.23 ± 9.6 years), t(456) = -3.60; p = 0.001. The level of risk of dependence on tramadol among the abusers was high, as 49.1% (56/114) of abusers were estimated to have a composite risk score of ≥ 27. Various socioenvironmental factors, including tension or fighting among family members (adjusted odds ratio [AOR] 7.73; 95% confidence interval [CI] 3.33-17.98; p < 0.001), abuse of drugs by a family member (AOR 2.27; 95% CI 1.26-4.11; p = 0.007), and having a friend who abused drugs (AOR 2.17; 95% CI 1.22-3.89; p = 0.009) were associated with tramadol abuse. Reasons given for using tramadol included pain relief and sexual enhancement.

CONCLUSION

The level of tramadol abuse and dependence was high. This calls for interventional programs, including health education, as dependency on tramadol has dire consequences on productivity.

Fixed dose drug combinations - are they pharmacoeconomically sound? Findings and implications especially for lower- and middle-income countries

Introduction: There are positive aspects regarding the prescribing of fixed dose combinations (FDCs) versus prescribing the medicines separately. However, these have to be balanced against concerns including increased costs and their irrationality in some cases. Consequently, there is a need to review their value among lower- and middle-income countries (LMICs) which have the greatest prevalence of both infectious and noninfectious diseases and issues of affordability.Areas covered: Review of potential advantages, disadvantages, cost-effectiveness, and availability of FDCs in high priority disease areas in LMICs and possible initiatives to enhance the prescribing of valued FDCs and limit their use where there are concerns with their value.Expert commentary: FDCs are valued across LMICs. Advantages include potentially improved response rates, reduced adverse reactions, increased adherence rates, and reduced costs. Concerns include increased chances of drug:drug interactions, reduced effectiveness, potential for imprecise diagnoses and higher unjustified prices. Overall certain FDCs including those for malaria, tuberculosis, and hypertension are valued and listed in the country's essential medicine lists, with initiatives needed to enhance their prescribing where currently low prescribing rates. Proposed initiatives include robust clinical and economic data to address the current paucity of pharmacoeconomic data. Irrational FDCs persists in some countries which are being addressed.
