RESUMO
BACKGROUND: The aim of this study was to assess the frequency of allopathic and complementary medicine use for preventing the infection with SARS-CoV-2 in Mexico. A descriptive and cross-sectional study was conducted using an online questionnaire among general adult population (n = 16,724) of the 32 Mexican states from March to November 2020. METHODS: The factors associated with the use, self-medication practice, and adverse reactions due the consumption of allopathic and complementary medicine to prevent infection with SARS-CoV-2 virus were assessed using a structured questionnaire. The suspected adverse reactions associated with the use of drugs or complementary medicine were reported. RESULTS: The prevalence (42.9%) of allopathic and/or complementary medicine use for preventing SARS-CoV-2 infection was mainly associated with unemployment [OR:2.026 (1.722-2.283)]. Acetaminophen (n = 2272) and vitamin C (n = 3252) were the main allopathic and complementary medicine products used to prevent SARS-CoV-2 infection, respectively. The prevalence of self-medication and adverse reactions was 35.3% and 4.8%, respectively. Self-medication [OR:1.930 (1.633-2.282)] and adverse reactions [OR:2.603 (2.015-3.363)] were mainly associated with individuals of low socioeconomic status. Hydroxychloroquine (21.2%) and chloroquine (15.2%) showed the highest prevalence of adverse reactions, which were mainly related to gastrointestinal disorders. CONCLUSION: The use of medications and complementary medicine to prevent SARS-CoV-2 infection is prevalent (almost one-half of the respondents) among Mexican population, and it is mainly associated with unemployment. Self-medication and the adverse reactions derived from self-medication are also prevalent and seem to be influenced by low socioeconomic status.
RESUMO
ETHNOPHARMACOLOGICAL RELEVANCE: Eryngium carlinae F. Delaroche (Apiaceae) is an herb used in folk medicine as a diuretic, analgesic, and anti-inflammatory agent. AIM OF THE STUDY: This work assessed the diuretic, antinociceptive, and anti-inflammatory actions of an ethanol extract from the leaves and stems of Eryngium carlinae (ECE). These ethnomedicinal properties of ECE were scientifically validated using in vitro and in vivo assays. MATERIALS AND METHODS: The antinociceptive and diuretic actions of ECE (10-200 mg/kg p.o.) were assessed with the acetic acid-induced writhing test and by using metabolic cages to house mice, respectively. The in vitro anti-inflammatory actions of ECE (1-500 µg/ml) were evaluated using LPS-stimulated primary murine macrophages, and the in vivo anti-inflammatory actions were assessed using the TPA-induced ear edema test (2 mg/ear) and carrageenan-induced paw edema test (50-200 mg/kg p.o.). The production of inflammatory mediators was estimated using in vitro and in vivo assays. RESULTS: ECE lacked antinociceptive and diuretic effects. ECE increased the production of IL-10 in LPS-stimulated macrophages (EC50 = 37.8 pg/ml) and the carrageenan-induced paw edema test (ED50 = 82.6 mg/kg). ECE showed similar in vivo anti-inflammatory actions compared to those observed with indomethacin. CONCLUSION: ECE exerts in vitro and in vivo anti-inflammatory effects by increasing the release of IL-10.
