: As a kind of haemoglobin, cytochrome P450 enzymes (CYP450) participate in the metabolism of many substances, including endogenous substances, exogenous substances and drugs. It is estimated that 60% of common prescription drugs require bioconversion through CYP450. The influence of macrolides on CYP450 contributes to the metabolism and drug-drug interactions (DDIs) of macrolides. At present, most studies on the effects of macrolides on CYP450 are focused on CYP3A, but a few exist on other enzymes and drug combinations, such as telithromycin, which can decrease the activity of hepatic CYP1A2 and CYP3A2. This article summarizes some published applications of the influence of macrolides on CYP450 and the DDIs of macrolides caused by CYP450. And the article may subsequently guide the rational use of drugs in clinical trials. To a certain extent, poisoning caused by adverse drug interactions can be avoided. Unreasonable use of macrolide antibiotics may enable the presence of residue of macrolide antibiotics in animal-origin food. It is unhealthy for people to eat food with macrolide antibiotic residues. So it is of great significance to guarantee food safety and protect the health of consumers by the rational use of macrolides. This review gives a detailed description of the influence of macrolides on CYP450 and the DDIs of macrolides caused by CYP450. Moreover, it offers a perspective for researchers to further explore in this area.

Abstract As global health services respond to the coronavirus pandemic, many prescribers are turning to experimental drugs. This review aims to assess the risk of drug–drug interactions in the severely ill COVID-19 patient. Experimental therapies were identified by searching ClinicalTrials.gov for ‘COVID-19’, ‘2019-nCoV’, ‘2019 novel coronavirus’ and ‘SARS-CoV-2’. The last search was performed on 30 June 2020. Herbal medicines, blood-derived products and in vitro studies were excluded. We identified comorbidities by searching PubMed for the MeSH terms ‘COVID-19’, ‘Comorbidity’ and ‘Epidemiological Factors’. Potential drug–drug interactions were evaluated according to known pharmacokinetics, overlapping toxicities and QT risk. Drug–drug interactions were graded GREEN and YELLOW: no clinically significant interaction; AMBER: caution; RED: serious risk. A total of 2378 records were retrieved from ClinicalTrials.gov, which yielded 249 drugs that met inclusion criteria. Thirteen primary compounds were screened against 512 comedications. A full database of these interactions is available at www.covid19-druginteractions.org. Experimental therapies for COVID-19 present a risk of drug–drug interactions, with lopinavir/ritonavir (10% RED, 41% AMBER; mainly a perpetrator of pharmacokinetic interactions but also risk of QT prolongation particularly when given with concomitant drugs that can prolong QT), chloroquine and hydroxychloroquine (both 7% RED and 27% AMBER, victims of some interactions due to metabolic profile but also perpetrators of QT prolongation) posing the greatest risk. With management, these risks can be mitigated. We have published a drug–drug interaction resource to facilitate medication review for the critically ill patient.

Complementary And Alternative

Complementary and alternative medicines such as herbal medicines are not currently part of the conventional medical system. As the popularity of and global market for herbal medicine grows among all age groups, with supporting scientific data and clinical trials, specific alternative treatments such as herbal medicine can be reclassified as a practice of conventional medicine. One of the most common conditions for which adults use herbal medicine is pain. However, herbal medicines carry safety concerns and may impact the efficacy of conventional therapies. Unfortunately, mechanisms of action are poorly understood, and their use is unregulated and often underreported to medical professionals. This review aims to compile common and available herbal medicines which can be used as an alternative to or in combination with conventional pain management approaches. Efficacy and safety are assessed through clinical studies on pain relief. Ensuing herb–drug interactions such as cytochrome modulation, additive and synergistic effects, and contraindications are discussed. While self-management has been recognized as part of the overall treatment strategy for patients suffering from chronic pain, it is important for practitioners to be able to also optimize and integrate herbal medicine and, if warranted, other complementary and alternative medicines into their care.

Wall Chart

“Black-box” warnings report valuable postmarketing safety data about prescription drugs, keeping practitioners informed about potential adverse events, drug interactions, key dosing information, monitoring and administration requirements, and at-risk patient populations. They are especially crucial for newly approved agents. A list of agents with black-box warnings does not currently exist; however Hospital Pharmacy will be publishing comprehensive lists by drug category in this column until November 2002. At that time, a complete list in wall chart form will be released. Hospital Pharmacy will update the data as salient information becomes available.

Abstract Objective: The aim of the present study was to analyze potential drug interactions and adverse reactions to NSAIDs in elderly users of a private drug distribution service. Method: A prospective, exploratory and descriptive study with a quantitative approach was performed. The elderly users of NSAIDs attended by the service were interviewed and their prescriptions analyzed between May and September, 2014. Analysis of drug interactions was performed through computerized databases. The post-sales analysis of adverse reactions was performed using the Adverse Drug Reaction Probability Scale. Statistical analysis was performed with the Chi-squared and Fisher's Exact tests. Results: The study evaluated 200 elderly persons, among whom women predominated (56.5%). The average age was 65 years ±10. The NSAIDs accounted for 38.7% of prescription drugs used, and included dipyrone (26.9%), nimesulide (22.8%) and ketoprofen (16.3%). A total of 8.5% of such drugs were considered inappropriate medications for the elderly. A total of 104 potential drug interactions were identified, of which 24% were considered highly clinically significant. The NSAIDs with the greatest risk of interactions were ketoprofen 46.2%, ketorolac 14.4%, nimesulide 12.5% and diclofenac 9.6%. In post-sales monitoring 30.5% of the elderly persons reported undesirable symptoms after the use of NSAIDs, with stomach discomfort the most prevalent (17%). Conclusion: The present study confirmed the importance of monitoring the use of NSAIDs among the elderly due to the increased risk of drug interactions and adverse reactions associated with age, concomitant diseases, multi- prescriptions and polypharmacy. The choice of appropriate drugs for the elderly, the reconciliation of all the medications taken by the patient, and effective pharmaceutical care are measures that can contribute to the rational and safe use of NSAIDs.

Regulatory Bodies

Use of complementary and alternative medicines (CAM) for preventive and therapeutic purposes has increased tremendously in the last two decades internationally. The manufacturers of these products are not required to submit proof of safety or efficacy to the Food and Drug Administration. As a result, the adverse effects and drug interactions associated with them are largely unknown. In this chapter, the author presents interactions of herbal medicines with other medicines (herbal or non-herbal). A large number of herbal drugs, including from single drug to a variety of mixtures have been used to treat kidney disorders. Herb-herb or herb drug interaction has been reported intensively during last decade, therefore it becomes important to keep an eye on the use of combination herbal therapy in order to avoid serious results because of interactions with each other. Due to the growing awareness about the interactions and side effects of herbal drugs/supplements over the past few years, regulatory bodies are working on these issues and pharmacopoeias are being developed for reference.

Potential Impact

The purpose of this paper is to explore the possibility that adverse reactions and drug interactions arising from the use of homeopathic and herbal medicines could lead to confusion when adverse reactions to conventional medicines are reported. An extensive literature review was conducted on the occurrence of adverse reactions and drug interactions following the use of homeopathic or herbal remedies, and the potential for these to confound adverse event reporting to conventional medicines considered. The survey demonstrates the potential for herbal remedies and homeopathic products, to produce adverse drug reactions or drug interactions, and shows the scope for potential for confusion with those arising from conventional medicines. There is a need for greater awareness that adverse reactions apparently due to a conventional medicine, might in reality be due to a herbal medicine or a drug interaction between a herbal medicine and a conventional drug, particularly when a health professional is unaware of the extent of a patient's selfmedication with alternative therapies.
