It has been revealed that T. repens contain important phytochemicals, which is the potential source of health-beneficial bioactive components for food and nutraceuticals industries.

Objectives Aluminium is present in food preparations, antacids and many medications. It causes neurodegeneration thereby resulting in a spectrum of neurological disorders such as dementia, Alzheimer’s disease and anxiety. Bacopa monnieri (BM) is widely used in ayurvedic medicine to improve memory functions. Its anxiolytic property was investigated in this study by using elevated plus maze (EPM) and plasma corticosterone level. Methods Thirty rats were assigned into five groups. Control group received distilled water, and 0.5% tween 80, AlCl 3 group received Aluminium Chloride (AlCl 3 ), Protective groups (BM100 + AlCl 3 group and BM200 + AlCl 3 group) received AlCl 3 and BM at two different doses, and the BM200 group received BM. The EPM experiment was performed at the end of the 4th week of oral administration of BM and AlCl 3 followed by the measurement of plasma corticosterone. Results Oral administration of AlCl 3 to rats increases the levels of anxiety as seen in a decrease in the percentage of entries into the open arms of EPM, an increase in grooming frequency and defecation index. However, the rats in the protective groups shown an increase in the percentage of open arm entries and rearing frequency, and decreased grooming frequency and defecation index. AlCl 3 alone treated group showed a significant increase in the plasma corticosterone levels compared to the control group. Whereas the protective groups have shown a significant decrease in the plasma corticosterone levels than the AlCl 3 alone treated group. Conclusions Hence the BM has potential role in reverting the anxiogenic effect of AlCl 3 in the amygdala as it is evident from the plasma corticosterone levels and the EPM parameters of different groups under study.

Background Albizia zygia (DC.) J.F. Macbr. (Leguminosae) has been used to treat mental disorders in traditional African medicine. Nonetheless, there is limited scientific evidence to justify its present use. The aim of this study was to evaluate the antidepressant activity of the hydroethanolic extract of A. zygia roots (AZE) in murine models. Methods AZE was evaluated in the tail suspension test, forced swim test, and the repeated open-space swim test of depression. In order to elucidate the mechanisms of action, the activity of AZE was re-evaluated after treating mice with selective inhibitors of monoamine biosynthesis. The potential of AZE to influence spontaneous locomotion was also examined. Results AZE (100–1000 mg/kg, p.o.) reduced the immobility time of mice in the tail suspension and forced swim tests (at least p < 0.05). In the repeated open-space swim test, AZE reduced the immobility time (at least p < 0.05) while concomitantly increasing the distance swam by mice (p < 0.01). However, the antidepressant-like activity of AZE was attenuated by α -methyl- para -tyrosine and reserpine (p < 0.0001) but not para -chlorophenylalanine. Conclusions The results of this study indicate that AZE possesses antidepressant-like properties and support the traditional use of AZE for the treatment of depression.

Introduction Adrenal insufficiency has a great impact on the prognosis of patients with traumatic brain injury. In healthy persons during normal day-to-day activity, the concentration of plasma cortisol is high in the morning, decreases during the day and rises again during night. But this diurnal rhythm is abolished in long-term unconscious patients and in those with disturbed sleep cycles. In addition, patients with central nervous system disease, who are conscious but have lesions in the temporal lobe, and the pretectal or hypothalamus area, demonstrate abnormal rhythms. Methods This cross-sectional study recruited 33 consecutive patients attending emergency medical departments of Prathima Institute of Medical Sciences Hospital between July 2017 and April 2018 with mild to severe traumatic head injury within 6 h of injury. The selected patients were mainly divided into three groups depending on the Glasgow Coma Scale (GCS) [mild head injury (14–15); moderate head injury (9–13); severe head injury (3–8)]. In each group, 11 patients were selected. GCS was calculated at the time of admission. The adrenal function of the patients was assessed by using the serum cortisol tests. Results In this comparative study of acute head injury among three groups, males are more prone to injury than females, with 81%, 90% and 72% in mild, moderate and severe injuries, respectively. The result mainly shows that the mean cortisol levels estimated were significantly increased in mild head injury and were with greater increase in cases of moderate & severe head injuries. Statistically significant positive correlation was observed between serum cortisol & GCS levels. Conclusions In this study of serum cortisol levels in head injury patients, we observed that there is increase in the serum cortisol level immediately after trauma. The increase is linearly related with the severity of head injury. Hence performing serum cortisol test is recommended for the assessment of adrenal function in patients with traumatic head injury.

Background Experiencing early-life stress plays an important role in the pathophysiology of anxiety disorders. Ferulic acid is a phenolic compound found in some plants which has several pharmacological properties. N-methyl-D-aspartate (NMDA) receptors are involved in the pathophysiology of mood disorders. In this study we aimed to assess the anxiolytic-like effect of ferulic acid in a mouse model of maternal separation (MS) stress by focusing on the possible involvement of NMDA receptors. Methods Mice were treated with ferulic acid (5 and 40 mg/kg) alone and in combination with NMDA receptor agonist/antagonist. Valid behavioral tests were performed, including open field test (OFT) and elevated plus maze test (EPM), while quantitative real time polymerase chain reaction (qRT-PCR) was used to evaluate gene expression of NMDA subunits ( GluN2A and GluN2B ) in the hippocampus. Results Findings showed that treatment of MS mice with ferulic acid increased the time spent in the central zone of the OFT and increased both open arm time and the percent of open arm entries in the EPM. Ferulic acid reduced the expression of NMDA receptor subunit genes. We showed that administration of NMDA receptor agonist (NMDA) and antagonist (ketamine) exerted anxiogenic and anxiolytic-like effects, correspondingly. Results showed that co-administration of a sub-effective dose of ferulic acid plus ketamine potentiated the anxiolytic-like effect of ferulic acid. Furthermore, co-administration of an effective dose of ferulic acid plus NMDA receptor agonist (NMDA) attenuated the anxiolytic-like effect of ferulic acid. Conclusions In deduction, our findings showed that NMDA, partially at least, is involved in the anxiolytic-like effect of ferulic acid in the OFT and EPM tests.

Objectives The present study attempts to understand the role of supraspinal nociceptive pain modulation in typical trigeminal neuralgia (TN) patients by using a conditioned pain modulation paradigm and estimation of plasma levels of two important neuromodulators; Calcitonin Gene-Related Peptide and  β -endorphin. Methods Twenty TN patients and 20 healthy, age and gender-matched subjects participated in the study. The participants' hot pain thresholds (HPT) were measured over their affected side on the face. Testing sites were matched for healthy controls. For the conditioned pain modulation their contralateral foot was immersed in noxious cold (5 °C) water bath (conditioning stimuli) for 30 s and HPT (testing stimuli) was determined before, during and till 5 min after the immersion. Plasma Calcitonin Gene-Related Peptide and β -endorphin levels were estimated to understand their role in disease pathogenesis and pain modulation. Results Change in HPT during foot immersion was significantly higher in healthy controls compared to TN patients (p<0.0001). The changes recorded in HPT in patients, were significant only in 2nd and 3rd minute post immersion. While in healthy controls, the effect lasted till the 4th minute. The concentration of beta-endorphin was significantly lower in TN patients (p=0.003) when compared to healthy controls. Conclusions The results suggest that there is an impairment in supraspinal pain modulation also known as Diffuse Noxious Inhibitory Controls in typical TN and that the reduced levels of β -endorphin may contribute to the chronic pain state experienced by patients.

Objectives This study was designed to examine the in vitro inhibitory activities of vital enzymes related to diabetes mellitus and different biochemical parameters of Phoenix dactylifera fruit based-diet in alloxan-induced diabetic rats. Methods The aqueous extract of P. dactylifera fruit based-diet was prepared and used for determination of in vitro antioxidants as well as α-amylase and α-glucosidase inhibitory activities using standard procedures. Also, 30 albino rats were induced by a single intraperitoneal injection of 150 mg/kg body weight of alloxan and grouped into A–D as normal rats placed on Dioscorea rotundata based-diet, diabetic control rats placed on D. rotundata based-diet, diabetic rats placed on D. rotundata based-diet and administered metformin orally per day, and diabetic rats placed on P. dactylifera fruit based-diet respectively. The animals were sacrificed on the fourth week of the experiment, and different biochemical parameters were evaluated. Results The P. dactylifera fruit based-diet extract demonstrated antioxidative potentials and inhibition against α-amylase and α-glucosidase activities in a dose-dependent manner. In addition, diabetic rats placed on the P. dactylifera fruit based-diet revealed significant (p<0.05) increase in body weight, insulin and glycogen levels, antioxidant enzyme activities, GLUT 2 and high density lipoprotein (HDL) concentrations when compared with the diabetic control group. Also, diabetic rats placed on P. dactylifera fruit based-diet indicate significant (p<0.05) reduction in fasting blood glucose, lipid peroxidation, cytokines levels, some gluconeogenesis enzyme activities, cholesterol, triglycerides, low-density lipoproteins and very low-density lipoproteins concentrations compared to the diabetic control animals. Conclusion This diet could be an alternative nutraceutical means of managing diabetes mellitus and its complications.

Objectives The belief of therapeutic effects of herbal remedies in diseases such as diabetes is rooted in medical history. The present study evaluated protective efficacy of the hydroalcoholic extract of Vitex pseudo-negundo leaves (VLHE) on the renal disorders in streptozotocin-induced diabetic rats. Methods Fifty Wistar male rats were recruited and divided into five groups of 10, including healthy controls and diabetic controls: three diabetic groups of which first group was treated with glibenclamide, and two groups treated with 250 and 500 mg/kg of VLHE, respectively, for six weeks. Renal biochemical tests and tissue histopathological evaluation were performed and the antioxidant status was examined. Results There were significant decreases in superoxide dismutase and glutathione peroxidase activities and increases in malondialdehyde levels in renal tissue of diabetic groups compared with healthy controls. In the VLHE-treated rats, fasting blood sugar, blood urea nitrogen and creatinine were declined, serum albumin elevated, kidney weight lowered, lipid peroxidation and reinforcement of the activities of antioxidant enzymes decreased compared with healthy groups. Histological assessments revealed that the vacuolar degeneration of tubules and shrinkage of glomeruli in VLHE-treated rats was decreased compared with diabetic rats. Conclusions The study suggested that administrating of VLHE in nephropathic rats ameliorated the disease by reduction of oxidative stress and increase in renal antioxidant enzyme activities.

Objectives Neera , nonfermented coconut inflorescence sap (NFCIS) from unopened spadix of Cocos nucifera L., is a well-known traditional beverage. But, scientific reports on its health benefits are limited. NFCIS is reported to exhibits free radical scavenging activity, and its chemical composition is found promising. In the present study, the effect of NFCIS on alleviating cisplatin-induced nephrotoxicity was analyzed in mice. Methods The renal toxicity was induced by cisplatin (16 mg/kg b.wt. ip) in Swiss albino mice. The antioxidant activity of NFCIS was evaluated by nitric oxide radical scavenging assay and phorbol-12-myristate-13-acetate–induced superoxide radical generation in mice peritoneal macrophages. Total polyphenolic content of sap was determined using Folin–Ciocalteu reagent. The phytochemicals present in NFCIS was identified using Fourier transform infrared (FT-IR) spectroscopy. Results NFCIS was found to scavenge nitric oxide (NO) radicals (IC 50  = 32 ± 2.47 μL/mL) and shown to inhibit superoxide (SO) generation (53.5 ± 2.1%) in macrophages. High polyphenolic content (193 µg gallic acid/mL) was determined in the sap. The FT-IR spectrum of NFCIS revealed the presence of several phytochemicals indicate its pharmaceutical and nutritional value. Cisplatin-induced hike in urea, creatinine and lipid peroxidation was significantly decreased to 65.16, 87.74 and 53.41% by NFCIS, respectively. Hb (42.37%) and total count (72.81%) were also found to be increased. Additionally, the activity of antioxidant enzymes superoxide dismutase, catalase, glutathione peroxidase and reduced glutathione was enhanced to 53.06, 40, 52.22 and 38.49%, respectively. Conclusions Results indicate that NFCIS effectively alleviates cisplatin-mediated renal toxicity by its antioxidant activity.

Objectives Rheum ribes L. is a perennial plant that belongs to the family of Polygonaceae, which is often used in traditional therapy because it possesses many bioactivities, such as antioxidant and antibacterial ones. Here we examined the effect of different R. ribes L. extracts on oxidative stress in experimental diabetic rats. Methods Thirty-six rats were divided into six groups as follows: group I, control group; group II, diabetic rats; group III, diabetic rats treated with the aqueous extract of R. ribes L. by gavage at 50 mg/kg for 15 days; group IV, diabetic rats treated by gavage with the ethanolic extract of R. ribes L. at 50 mg/kg for 15 days; group V, nondiabetic rats treated by gavage with the aqueous extract of R. ribes L. at 50 mg/kg for 15 days; group VI, nondiabetic rats treated by gavage with the ethanol extract of R. ribes L. at 50 mg/kg for 15 days. After 15 days, the animals were sacrificed and the liver and kidney tissues of each animal were isolated. Superoxide dismutase (SOD), catalase (CAT), malondialdehyde (MDA) and glutathione peroxidase (GSH-Px) activities in the tissue samples were measured, and histopathologic examination was carried out. Results R. ribes L. was effective in reducing the oxidative stress and increasing the levels of the antioxidant enzymes. Increased levels of MDA and decreased levels of SOD, CAT and GSH-Px were observed in both the liver and kidney tissues in group II. Decreased levels of MDA and increased levels of SOD, CAT and GSH-Px were observed in group III compared with group II. In group IV, decreased levels of MDA and increased levels of SOD, CAT and GSH-Px were observed in comparison with group II. Conclusions Diabetes increases oxidative stress and causes a decrease in antioxidant enzyme levels. Both aqueous and ethanolic extracts of R. ribes L. decrease oxidative stress activity and increase the levels of antioxidant enzymes. The ethanol extract of R. ribes L. has a higher antioxidant effect than the aqueous extract.

Background Metabolic diseases are associated with impaired renal function which accelerates chronic kidney disease (CKD) progression. The aim of this study was to investigate the effects of 16-week honey supplementation on renal function, metabolic acidosis and renal abnormalities in Wistar rats fed a high-fat diet (HFD). Methods Wistar rats were fed a HFD and sucrose (30%) solution and randomly grouped and treated. Group 1 was fed rat chow and treated with drinking water while groups 2, 3, 4 and 5 were fed a HFD and treated with drinking water, 1, 2 and 3 g/kg body weight (BW) of honey, respectively, once daily for 16 weeks. After the rats were sacrificed, the serum samples were obtained and used for the analysis of total cholesterol, urea, creatinine, sodium, potassium, calcium, bicarbonates and chloride ions. Histopathological examinations of the kidneys were performed. Results The serum creatinine and anion gap levels were significantly (p < 0.01) higher while the levels of serum total calcium and ionized fraction were significantly (p < 0.01) lower in HFD-fed control rats than in chow-fed rats. The kidney of HFD-fed control rats was characterized by tubular necrosis, glomerular atrophy, hemorrhage and severe focal aggregate inflammatory (FAIC) cells. Honey treatment (1, 2 or 3 g/kg BW) prevented elevations in serum creatinine while it restored serum levels of total calcium and ionized calcium towards those in rats fed chow only. All the three doses of honey also significantly (p < 0.01) reduced anion gap and ameliorated renal lesions. Honey treatment (2 g/kg BW) significantly (p < 0.05) increased bicarbonate and chloride ion in HFD-fed rats compared with HFD-fed control rats. Conclusions Sixteen-week honey supplementation ameliorates renal dysfunction, metabolic acidosis and renal morphological abnormalities in HFD-fed Wistar rats.

Background Due to increasing prevalence of diabetes and associated endothelial dysfunction, this study was carried out to investigate the effects of co-administration of adrenoceptor blockers (prazosin and propranolol) and glibenclamide on plasma biomarkers of endothelial functions in diabetic rats. Methods Experiments were carried out on 35 male Wistar rats (170–200 g). They were divided into seven groups (n=5) as follows: normal control, diabetic control, diabetic + glibenclamide (GLB-5mg/kg/day), diabetic+ prazosin (PRZ-0.5 mg/kg/day), diabetic + PRZ + GLB, diabetic + propranolol (PRP-10 mg/kg/day), diabetes + PRP + GLB. Experimental diabetes was induced with streptozotocin (60 mg/kg) and drugs were administered orally for 3 weeks. Blood pressure was measured and animals were sacrificed afterwards. Blood samples were collected by cardiac puncture, and major marker of endothelial functions, nitric oxide derivatives (NOx), as well as superoxide dismutase (SOD) and malondialdehyde (MDA) were measured on the plasma. The aorta was harvested for histological examination. Data were subjected to descriptive statistics and analysed using ANOVA at α 0.05. Results There was a significant increase in levels of NOx and SOD, and a decrease in MDA level in diabetic treated groups compared to diabetic control. Mean blood pressure increased in diabetic control and diabetic + GLB group when compared with normal control, while it was mildly reduced in diabetic group treated with PRZ and PRP, and co-administered GLB. More so, Aorta histology was altered in diabetic control groups when compared with normal control and all diabetic treated groups. Conclusions Results from this study suggest that PRZ, PRP, and GLB (singly and in combined therapy) could have a restorative effect on endothelial functions in diabetes.

Objectives Calcium deregulation in diabetes mellitus (DM) is central to the brain–heart axis pathology. This has led to the use of medical plants in complementary medicine such as Amaranthus hypochondriacus (GA). The objective of the study was to establish the effects of grain amaranth feed supplementation on calcium, s100al protein and antioxidant levels on the brain–heart axis in diabetic male Wistar rats. Methods The study involved six groups ( n =5) with DM being induced in 20 rats. To the diabetic rats, Group I received mixtard ® , Group II was positive control, Groups III and IV received GA feed supplementation at 25 and 50%. In the nondiabetic rats ( n =10), Group V received 50% grain amaranth while Group VI was the negative control. The brain and heart tissues were harvested after five weeks and processed using standard methods. Results Grain amaranth feed supplementation led to improved calcium levels in DM as compared to the positive control. This also led to increased s100a1, antioxidant levels in the brain–heart axis during DM. This then protected the tissues against oxidative damage, thus preserving tissue function and structure. Conclusions Grain amaranth’s actions on calcium signaling subsequently affected s100a1 protein levels, leading to improved tissue function in diabetes.

Objectives The present study aimed to evaluate the efficacy of Aloe vera in the methylcellulose-induced ocular hypertension model. Methods Fifty-six rabbits were randomly divided into seven groups. Intraocular pressure (IOP) was raised by anterior chamber injection of 2% methylcellulose in all the groups except the normal control group. Disease control animals were treated with sterile water and active control with topical 0.5% timolol 12 hourly; 6 and 12% A. vera gel topical solutions 8 hourly were given in group IV and V, respectively; 6 and 12% A. vera gel solutions along with timolol were given in group VI and VII animals, respectively. Mean IOP values and percentage of reduction in IOP were compared at 15 min, 30 min, 1 h, 2 h, 4 h, 8 h, 12 h, 24 h, 36 h, and 48 h. Results A. vera gel solutions (6 and 12%) showed a significant reduction in mean IOP from 4 to 2 h time points, respectively, whereas, A. vera gel solutions (6 and 12%) + timolol showed significant less mean IOP from a 30 min time point as compared with disease control. A. vera gel solutions (6 and 12%) showed 8.6 and 10.4% more reduction in IOP, respectively (66.8 ± 4.9% and 68.6 ± 5.4% vs. 58.2 ± 2.3%; p > 0.05), whereas 6 and 12% A. vera gel solutions along with timolol showed 14.5 and 16.2% more reduction in IOP, respectively (72.7 ± 4.7% and 74.4 ± 4.1% vs. 58.2 ± 2.3%; p < 0.05), than disease control group at 48 h. Conclusions Six and twelve percent A. vera gel solutions reduced the IOP effectively. Concurrent treatment with 12% A. vera gel and timolol produced the maximum reduction in IOP.

Objectives Traditionally, Justicia carnae is used in treatment of anaemia. In this study, the haematoprotective effects of ethanol and aqueous leaf extracts of J. carnae were evaluated in sodium nitrate-treated male rats. Methods Acute toxicity values, phytochemical, vitamin B12, vitamin C and iron contents of the extracts were analytically determined. Seventy (70) adult rats divided into seven groups of 10 rats each were assigned specific treatments. Group I served as the normal control, while group II was treated with the induction agent (sodium nitrate (NaNO 3 ), 300 mg/kg body weight) only. Group III was pretreated with fesolate before NaNO 3 induction, while groups IV to VII received leaf extracts in addition to induction. The daily oral treatments lasted for 28 days and at the end, the animals were sacrificed and blood samples were collected for haematological studies. Results Results obtained revealed the presence of flavonoids, phenolic compounds, tannins, terpenes, saponins, alkaloids, vitamins C, B 12 and iron in both extracts. The LD 50 value for each extract was >5,000 mg/kg body weight. There were increased significant co-administration effects (p < 0.05) in red blood cell, packed cell volume, haemoglobin, white blood cells and platelet counts in the extract and fesolate treated groups compared to negative control. Bleeding time values were not significantly altered in all test groups (p > 0.05), but the increased clotting time values were lowered to about normal values following treatment with the extracts. Conclusions The results showed that J. carnae extract has haematoprotective potential and may be a good candidate for haematopoiesis.

Objectives Ziziphus abyssinica (ZA) is employed in managing several ailments in Traditional African Medicine. Scientific evaluations are necessary to ascertain the medicinal potential of ZA as a source of new drug molecules. This study investigated the possible therapeutic benefit of ZA leaf (ZAL) and root bark (ZARB) extracts in an experimental model of multi-organ injuries induced by phenylhydrazine (PHZ). Methods Hyperbilirubinaemia, hepatotoxicity, nephrotoxicity and splenic injuries were induced by pretreating albino rats with PHZ (40 mg/kg, p.o. ) for two alternate days. Afterward, six out of the eight groups of rats (n = 5) used were treated with either ZAL or ZARB (30, 100 and 300 mg/kg/day, p.o .) for seven days. Naïve control rats received saline without PHZ whereas negative control group received saline after PHZ. After one week of treatment, rats were sacrificed and blood collected for assessment of haematological and biochemical parameters. Liver, kidney and spleen sections were processed for histology and examined under light microscope. Results Data indicate that PHZ significantly (p < 0.05) increased total bilirubin, serum alanine aminotransferase, aspartate aminotransferase, blood urea nitrogen (BUN), creatinine and BUN/creatinine ratio whereas red blood cell count was significantly reduced. These anomalies were significantly reversed in rats treated with ZAL or ZARB. The therapeutic effect of the extracts was supported by photomicrographs of the liver, kidney, and spleen of rats which revealed recovery from PHZ-mediated pyknosis, glomerular degeneration and multiple splenic necrosis respectively. Conclusions Overall, data from this study suggest that ZA may be useful in multiple organ injuries associated with PHZ-like xenobiotic toxicity.

Background Boerhavia coccinea (Nyctaginaceae) is an herbaceous plant used for the treatment of pain. The aim of this study was to evaluate the antinociceptive and anti-inflammatory activities of the aqueous (AEBC) and ethanol (EEBC) extracts of Boerhavia coccinea as well as the major fractions (F 1 , F 2 and F 3 ) from EEBC. Methods The antinociceptive effect of the extracts and fractions was evaluated using formalin test. AEBC, EEBC and F 1 were selected and further evaluated acutely (24 h) and chronically (16 days) in Complete Freund’s Adjuvant (CFA)-induced persistent inflammatory pain for their antihyperalgesic and anti-inflammatory effects. They were administered orally (100 and 200 mg/kg/day) from 48 h following the intraplantar injection of 100 µL of CFA. After the 16 days of chronic treatment, rats’ spinal cord and brain were collected for the evaluation of oxidative stress parameters namely nitric oxide (NO), malondialdehyde (MDA), superoxide dismutase (SOD) and catalase (CAT). Results AEBC, EEBC and F 1 significantly inhibited the first and second phases of the formalin-induced pain. They significantly reduced the hyperalgesia both in acute and chronic treatments. These extracts showed no acute anti-inflammatory effect. AEBC and EEBC exhibited anti-inflammatory activities after repeated administration. AEBC, EEBC and F 1 significantly reduced MDA level and significantly increased SOD and catalase activities, mainly in the spinal cord. AEBC and EEBC also reduced the NO production in the spinal cord. Conclusions Boerhavia coccinea extracts and F 1 possess potent antinociceptive activity which is not related to their anti-inflammatory properties. Their antioxidant effects may contribute to these activities in chronic treatment.

Objectives Rhabdomyolysis is a rare syndrome in which a serious muscle damage suddenly appears, with the possible occurrence of severe complications such as kidney failure, electrolyte imbalances and death, and represents the most severe form of statin-induced muscle injury. Case presentation Here we present the case of a 55-year-old woman who started therapy with amoxicillin clavulanic acid on a background of atorvastatin therapy, resulting in rhabdomyolysis. Conclusions This case highlights the importance of evaluating potential drug interactions in patients taking statin and the need of monitoring clinical and laboratory findings suggestive of rhabdomyolysis.
