Dietary substances, including herbal products and citrus juices, can perpetrate interactions with conventional medications. Regulatory guidances for dietary substance-drug interaction assessment are lacking. This deficiency is due in part to challenges unique to dietary substances, a lack of requisite human-derived data, and limited jurisdiction. An in vitro-in vivo extrapolation (IVIVE) approach to help address some of these hurdles was evaluated using the exemplar dietary substance grapefruit juice (GFJ), the candidate marker constituent 6',7'-dihydroxybergamottin (DHB), and the purported victim drug loperamide. First, the GFJ-loperamide interaction was assessed in 16 healthy volunteers. Loperamide (16 mg) was administered with 240 ml of water or GFJ; plasma was collected from 0 to 72 hours. Relative to water, GFJ increased the geometric mean loperamide area under the plasma concentration-time curve (AUC) significantly (1.7-fold). Second, the mechanism-based inhibition kinetics for DHB were recovered using human intestinal microsomes and the index CYP3A4 reaction, loperamide N-desmethylation (KI [concentration needed to achieve one-half kinact], 5.0 ± 0.9 µM; kinact [maximum inactivation rate constant], 0.38 ± 0.02 minute(-1)). These parameters were incorporated into a mechanistic static model, which predicted a 1.6-fold increase in loperamide AUC. Third, the successful IVIVE prompted further application to 15 previously reported GFJ-drug interaction studies selected according to predefined criteria. Twelve of the interactions were predicted to within the 25% predefined criterion. Results suggest that DHB could be used to predict the CYP3A4-mediated effect of GFJ. This time- and cost-effective IVIVE approach could be applied to other dietary substance-drug interactions to help prioritize new and existing drugs for more advanced (dynamic) modeling and simulation and clinical assessment.

Bile salt therapy is not used in patients with steatorrhea due to bile salt deficiency because of fear that severe diarrhea would be caused or exacerbated. We report a patient who previously had had colectomy, partial ileectomy, and ileostomy for Crohn's disease. She had severe steatorrhea due to bile salt deficiency and severe diarrhea (the latter apparently due to fatty acid inhibition of electrolyte and water absorption). The diarrhea was improved by loperamide, but severe steatorrhea and malnutrition persisted. The steatorrhea and malnutrition were corrected by ox bile, without an increase in diarrhea. Presumably, the deleterious effect of bile salts per se on small bowel absorption of water and electrolytes was mitigated by correction of fat malabsorption. At least in this patient, bile salt therapy was highly beneficial.

In the castor oil test, twenty (20) adult Sprague-Dawley rats were randomized to a negative control (normal saline, n=5), a positive control (5mg/kg loperamide, n=5), and two test groups. The low dose test group received 200mg/kg Bidens biternata extract (n=5) while the high dose test group received 400mg/kg B. biternata extract (n=5). Castor oil (4ml/kg) was then administered to the animals one hour after administration of the respective treatments after which the total mass of fecal output excreted after four (4) hours was determined. In the charcoal meal test fifteen (15) Sprague Dawley rats were randomized to a control group (normal saline 5ml/kg orally, n=5), a positive control group (atropine sulfate 0.1mg/kg i.p., n=5) and a test group (400mg/kg B. biternata extract, n=5). Charcoal meal was then administered via oral gavage to each rat thirty (30) minutes after the administration of the various treatments. The distance covered by the charcoal meal from the pylorus was then determined after sacrifice of the animals thirty minutes after the meal. In the enteropooling test twenty (20) Sprague-Dawley rats were randomized to a control group (5% v/v ethanol in normal saline, n=5), a positive control group (5mg/kg loperamide, n=5) and a test group (400mg/kg B. biternata extract, n=5). For each group prostaglandin E2 (PGE2) (100μg/kg) was administered immediately after the treatments. The animals were then sacrificed half an hour later and the volume of the small intestine contents determined. The effects of different concentrations of B. biternata extract (0.5. 1.0, 2.0, 3.0 and 5.0mg/ml) on jejunal contraction were investigated and a dose-response curve constructed using the experimental data after which The ED50 dose was determined. The effect of tamsulosin (α1 adrenergic blocker), yohimbine (α2 adrenergic blocker), propranolol (β adrenergic blocker) and naloxone (μ opioid blocker) on the contractile activity of the extract were also investigated. The experimental data were expressed as mean±standard error of mean (SEM) and then analyzed using one-way ANOVA followed by Tukey's post hoc test in cases of significance (set at p<0.05).

A shortened small intestine may end at a stoma or be anastomosed to the colon. Patients with a jejunostomy, but not those with a colon, lose large amounts of sodium. The intake and absorption of sodium can be increased by sipping a sodium-glucose solution; stomal loss can be reduced by restricting water or low-sodium drinks. If a stoma is situated less than 100 cm along the jejunum, a constant negative sodium balance may necessitate parenteral saline supplements. Gastric anti-secretory drugs or a somatostatin analogue reduce jejunostomy losses in such patients but do not restore a positive sodium balance. Loperamide or codeine phosphate benefit some patients. Magnesium deficiency can usually be corrected by oral magnesium oxide supplements. An elemental or hydrolysed diet is not beneficial. Patients with a jejunostomy can maintain a normal diet without fat reduction. When the colon is present, unabsorbed carbohydrate is fermented to absorbable short chain fatty acids. Unabsorbed long chain fatty acids and bile salts cause watery diarrhoea and increased colonic oxalate absorption with hyperoxaluria. Such patients benefit from a high carbohydrate, low-fat and low-oxalate diet. Parenteral nutrition is needed only by the few patients unable to maintain health or avoid socially disabling diarrhoea despite these measures.

The aqueous and ethanol extracts exhibited significant in vitro antidiarrheal activity compared to the standard drug ciprofloxacine (10 µg/mL). The plant extracts showed significant (P <0.05) and dose-dependent antidiarrheal activity comparable to that of the reference drug, loperamide (10 mg/kg). The plant extracts exhibited significant in vitro antiprotozoal activity against both protozoa compared to the standard amebicidal and giardicidal drugs, metronidazole and emetine.

The Fischer 344 (F344) and Lewis (LEW) inbred rat strains differ on a host of biochemical, neuroanatomical, immunological and behavioral endpoints. One behavioral difference of interest is their differential reactivity to the aversive effects of morphine as indexed by the conditioned taste aversion preparation (aversions acquired by F344 rats are significantly greater than those acquired by the LEW strain). This differential effect appears to be specific to opioids that work primarily on the mu opioid receptor. Given that morphine works systemically, it is unknown whether these differential effects in F344 and LEW animals are centrally or peripherally mediated. To address this issue, the present study investigated the ability of the peripherally acting mu preferring opioid agonist loperamide to induce differential taste aversions in F344 and LEW animals. Both F344 and LEW animals acquired dose-dependent taste aversions to the loperamide-associated solution with no difference between them. Additionally, control animals initially injected with vehicle during aversion training with loperamide and subsequently conditioned with morphine displayed the typical aversive profile to morphine (F344>LEW). Although the basis for the present data is unknown, their relation to morphine-induced taste aversions and the role of the interaction of stimulus effects of drugs that produce differential abuse liability were discussed.

Human serum albumin (HSA) nanoparticles (NP) were prepared by desolvation. Insulin or an anti-insulin receptor monoclonal antibody (29B4) were covalently coupled to the HSA NP, using the NHS-PEG-MAL-5000 crosslinker. Loperamide-loaded HSA NP with covalently bound insulin or the 29B4 antibodies induced significant antinociceptive effects in the tail-flick test in ICR (CD-1) mice after intravenous injection, demonstrating that insulin or these antibodies covalently coupled to HSA NP are able to transport loperamide across the blood-brain barrier (BBB) which it normally is unable to cross. Control loperamide-loaded HSA NP with immunoglobulin G antibodies yielded only marginal effects. The loperamide transport across the BBB using the NP with covalently attached insulin could be totally inhibited by the pretreatment with the antibody 29B4.

CYP2B6, CYP2C8, CYP2D6, and CYP3A4 catalyze LOP N-demethylation in human liver microsomes, and among them, CYP2C8 and CYP3A4 may play a crucial role in LOP metabolism at the therapeutic concentrations of LOP. Coadministration of these P450 inhibitors may cause drug interactions with LOP. However, the clinical significance of potential interaction of LOP metabolism by CYP2C8 and CYP3A4 inhibitors should be studied further.

The purpose of this study was to examine whether in vivo drug distribution to the brain can be reconstructed by integrating P-glycoprotein (P-gp)/mdr1a expression levels, P-gp in vitro activity, and drug unbound fractions in mouse plasma and brain. For 11 P-gp substrates, in vitro P-gp transport activities were determined by measuring transcellular transport across monolayers of mouse P-gp-transfected LLC-PK1 (L-mdr1a) and parental cells. P-gp expression amounts were determined by quantitative targeted absolute proteomics. Unbound drug fractions in plasma and brain were obtained from the literature and by measuring brain slice uptake, respectively. Brain-to-plasma concentration ratios (K(p brain)) and its ratios between wild-type and mdr1a/1b(-/-) mice (K(p brain) ratio) were obtained from the literature or determined by intravenous constant infusion. Unbound brain-to-plasma concentration ratios (K(p,uu,brain)) were estimated from K(p brain) and unbound fractions. Based on pharmacokinetic theory, K(p brain) ratios were reconstructed from in vitro P-gp transport activities and P-gp expression amounts in L-mdr1a cells and mouse brain capillaries. All reconstructed K(p brain) ratios were within a 1.6-fold range of observed values. Augmentin Overdose K(p brain) then was reconstructed from the reconstructed K(p brain) ratios and unbound fractions. K(p,uu,brain) was reconstructed as the reciprocal of the reconstructed K(p brain) ratios. For quinidine, loperamide, risperidone, indinavir, dexamethasone, paclitaxel, verapamil, loratadine, and diazepam, the reconstructed K(p brain) and K(p,uu,brain) agreed with observed and estimated in vivo values within a 3-fold range, respectively. Thus, brain distributions of P-gp substrates can be reconstructed from P-gp expression levels, in vitro activity, and drug unbound fractions.

Eighty patients receiving PCI were randomly assigned to the control group and the treatment group, 40 in each. All patients used loperamide injection as the contrast media, and received routine medicines such as enteric coated aspirin and Betaloc, as well as routine rehydration therapy. As for patients in the treatment group, 20 mL DHI was intravenously dripped by adding in 250 mL 0.9% sodium chloride injection from 2 -3 days before PCI to 3 days after PCI, once daily. The levels of serum creatinine (SCr), cystatin C (CysC), urine micro-albumin (mAlb), and beta2-microglobulin (beta2-MG) were measured before PCI, and 24, 48, 72 h after PCI. The occurrence of radio contrast-induced Cialis 5 Mg Reviews nephropathy (RCIN) of the two groups was observed.

We evaluated the effects of σ1-receptor inhibition on μ-opioid-induced mechanical antinociception and constipation. σ1-Knockout mice exhibited marked mechanical antinociception in response to several μ-opioid analgesics (fentanyl, oxycodone, morphine, buprenorphine, and tramadol) at systemic (subcutaneous) doses that were inactive in wild-type mice and even unmasked the antinociceptive effects of the peripheral μ-opioid agonist loperamide. Likewise, systemic (subcutaneous) or local (intraplantar) treatment of wild-type mice with the selective σ1 antagonists BD-1063 [1-[2-(3,4-dichlorophenyl)ethyl]-4-methylpiperazine dihydrochloride] or S1RA [4-[2-[[5-methyl-1-(2-naphthalenyl)1H-pyrazol-3-yl]oxy]ethyl] morpholine hydrochloride] potentiated μ-opioid antinociception; these effects were fully reversed by the σ1 agonist PRE-084 [2-(4-morpholinethyl)1-phenylcyclohexanecarboxylate) hydrochloride], showing the Motilium Brand Name selectivity of the pharmacological approach. The μ-opioid antinociception potentiated by σ1 inhibition (by σ1-receptor knockout or σ1-pharmacological antagonism) was more sensitive to the peripherally restricted opioid antagonist naloxone methiodide than opioid antinociception under normal conditions, indicating a key role for peripheral opioid receptors in the enhanced antinociception. Direct interaction between the opioid drugs and σ1 receptor cannot account for our results, since the former lacked affinity for σ1 receptors (labeled with [(3)H](+)-pentazocine). A peripheral role for σ1 receptors was also supported by their higher density (Western blot results) in peripheral nervous tissue (dorsal root ganglia) than in several central areas involved in opioid antinociception (dorsal spinal cord, basolateral amygdala, periaqueductal gray, and rostroventral medulla). In contrast to its effects on nociception, σ1-receptor inhibition did not alter fentanyl- or loperamide-induced constipation, a peripherally mediated nonanalgesic opioid effect. Therefore, σ1-receptor inhibition may be used as a systemic or local adjuvant to enhance peripheral μ-opioid analgesia without affecting opioid-induced constipation.

For brain imaging, after the injection of (11)C-dLop the concentration Levitra 40 Mg Dose of radioactivity in the brain was low (standardized uptake value, approximately 15%) and stable after approximately 20 min. In contrast, uptake of radioactivity in the pituitary was about 50-fold higher than that in the brain. The plasma concentration of (11)C-dLop declined rapidly, but the percentage composition of plasma was unusually stable, with the parent radiotracer constituting 85% of total radioactivity after approximately 5 min. The rate of brain entry was low (K(1) = 0.009 +/- 0.002; n = 4). For whole-body imaging, as a measure of radiation exposure to the entire body the effective dose of (11)C-dLop was 7.8 +/- 0.6 muSv/MBq (n = 8).

The antispasmodic and vasodilator activities of a newly synthesized piperidine derivative (1-(4'-fluorophenacyl)-4-hydroxy-4-phenyl-piperidinium chloride) were studied in vitro. The test compound exhibited a dose-dependent relaxant effect on the spontaneous and K+ (75 mM)-induced contractions of isolated rabbit jejunum with respective EC50 values of 0.01 mM (0.01-0.02, 95% Cl) and 0.30 mM (0.17-0.56). The Ca++ channel blocking (CCB) activity was confirmed when the test compound (0.1-0.2 mM) shifted the Ca++ dose-response curves to the right, similar to that produced by verapamil (0.1-1.0 microM), a standard CCB. In the isolated rabbit aorta, the test compound showed a dose-dependent vasodilator effect on K+ (75 mM)-induced contractions with an Cymbalta Generic Release 2013 EC50 value of 0.08 mM (0.02-0.26) while also suppressed the norepinephrine (1 microM) control peak responses with EC50 value of 0.08 mM (0.05-0.13, n=5). When tested in Langendorff perfused rabbit heart preparation, the test compound exhibited a negligible inhibitory effect on the rate or force of atrial and ventricular contractions when tested up to 5 mM. The results show smooth muscle-selective relaxant effect of the test compound on intestinal and vascular preparations mediated possibly via blockade of voltage and receptor-operated Ca++ channels.

Capecitabine is an oral prodrug of 5-fluorouracil that is indicated for the treatment of breast and colorectal cancers. A three-step in vivo-targeted activation process requiring carboxylesterases, cytidine deaminase, and thymidine phosphorylase converts capecitabine to 5-fluorouracil. Carboxylesterases hydrolyze capecitabine's carbamate side chain to form 5'-deoxy-5-fluorocytidine (5'-DFCR). This study examines the steady-state kinetics of recombinant human carboxylesterase isozymes carboxylesterase (CES) 1A1, CES2, and CES3 for hydrolysis of capecitabine with a liquid chromatography/mass spectroscopy assay. Additionally, a spectrophotometric screening assay was utilized to identify drugs that may inhibit carboxylesterase activation of Himplasia Drug capecitabine. CES1A1 and CES2 hydrolyze capecitabine to a similar extent, with catalytic efficiencies of 14.7 and 12.9 min(-1) mM(-1), respectively. Little catalytic activity is detected for CES3 with capecitabine. Northern blot analysis indicates that relative expression in intestinal tissue is CES2 > CES1A1 > CES3. Hence, intestinal activation of capecitabine may contribute to its efficacy in colon cancer and toxic diarrhea associated with the agent. Loperamide is a strong inhibitor of CES2, with a K(i) of 1.5 muM, but it only weakly inhibits CES1A1 (IC(50) = 0.44 mM). Inhibition of CES2 in the gastrointestinal tract by loperamide may reduce local formation of 5'-DFCR. Both CES1A1 and CES2 are responsible for the activation of capecitabine, whereas CES3 plays little role in 5'-DFCR formation.
