ABSTRACT
Selective serotonin reuptake inhibitors (SSRIs) are associated with urinary problems attributed to their central effects. ESC is a preferred SSRI and several case reports described that ESC is related to urinary retention. However, the direct effect of ESC on detrusor contractility is still not completely elucidated. Thus, we investigated the effect of ESC on detrusor contractility and mechanism(s) of its action in isolated mouse detrusor strips. Molecular docking and measurement of intracellular calcium were performed to determine the possible calcium channel blocking effect of ESC. The contractile responses to carbachol (CCh), KCl and electrical field stimulation of detrusor strips were significantly abolished by ESC (10 or 100 µM). ESC relaxed KCl-precontracted detrusor strips concentration-dependently, which was not affected by tetraethylammonium, glibenclamide, 4-aminopyridine, propranolol, L-NAME or methylene blue. ESC (10 or 100 µM) reduced both the CaCl2- and CCh-induced contractions under calcium-free conditions, indicating the role of calcium-involved mechanisms in ESC-mediated relaxation. Furthermore, ESC significantly decreased Bay K8644-induced contraction and the cytosolic calcium level in fura-2-loaded A7r5 cells. Molecular docking study also revealed the potential of ESC to bind L-type calcium (Cav1) channels. Our results demonstrate that ESC inhibits detrusor contractility via blocking Cav1 channels, which provides evidence for the direct effect of ESC on detrusor contractility and its mechanism.

This prospective multicentre cohort study investigated pregnancy outcomes after fingolimod use for multiple sclerosis during pregnancy. Pregnancy outcomes of 63 fingolimod and 62 interferon-ß-exposed pregnancies were compared. Rates of major congenital anomalies (MCA) were 4.8% (2/42) in the fingolimod group versus 2.3% (1/44) in the interferon-ß group (odds ratio, 2.2; 95% confidence interval, 0.2-24.6). The adjusted hazard ratio for spontaneous abortion in fingolimod versus interferon-ß-exposed pregnancies was 0.6 (95% confidence interval, 0.2-1.8). Further studies are needed to definitely rule out a moderately increased MCA risk after fingolimod exposure during pregnancy.

Trimebutine maleate (TMB), a widely prescribed drug for functional gastrointestinal disorders, has been reported to regulate smooth muscle contractility by modulating multiple ion channel activities in the gastrointestinal tract. However, its action on isolated aorta has not yet been reported. The aim of the present study was to evaluate in vitro vasorelaxant properties and the underlying pharmacological mechanisms of TMB in isolated rat thoracic aortic rings. Vascular activity experiments were performed on thoracic aorta isolated from Sprague-Dawley rats in vitro, including endothelium-intact and endothelium-denuded aortic rings. TMB (10-10 -10-5 mol/L) induced relaxation in endothelium-intact aortic rings precontracted by phenylephrine with a potency similar to that of carbachol. TMB-induced relaxation was not altered by glibenclamide and atropine in endothelium-intact aortic rings. However, L-NAME and endothelium denudation significantly reduced but not completely reversed the vasorelaxant effect of TMB. Also, TMB-induced relaxation wasn't affected by diclofenac in endothelium-intact aortic rings. TMB at 10-5 mol/L significantly reduced the CaCl2 -induced contractions in endothelium-intact aortic rings stimulated with KCl, but not stimulated with phenylephrine under Ca2+ free conditions. Moreover, TMB at 10-5 mol/L effectively attenuated Bay-K8644-induced contractions in aortic rings. These results suggest that TMB-induced relaxation was mediated by both endothelium-dependent and endothelium-independent manner in isolated rat thoracic aorta. The mechanism of TMB-induced relaxation at low concentrations is partially related to NO- and endothelium-dependent but unrelated to prostanoids formation. However, inhibition of Ca2+ influx through voltage-operated calcium channels and L-type Ca2+ channel blocking effect appears to be involved in the mechanism of vasorelaxant effect of TMB at high concentrations.
ABSTRACT
OBJECTIVE: We evaluated the myocardial damage in rats treated with doxorubicin (DOX) alone and in combination with nitric oxide synthase (NOS) inhibitors. MATERIALS AND METHODS: Twenty-four male Sprague Dawley rats (12 weeks old, weighing 262±18 g) were randomly assigned into 4 groups (n=6). Group I was the control group. In Group II, rats were treated with intraperitoneal (ip) injections of 3 mg/kg DOX once a week for 5 weeks. In Group III, rats received weekly ip injections of 30 mg/kg L-NAME (nonspecific NOS inhibitor) 30 min before DOX injections for 5 weeks. In Group IV, rats received weekly ip injections of 3 mg/kg L-NIL (inducible NOS inhibitor) 30 min before DOX injections for 5 weeks. Rats were weighed 2 times a week. At the end of 6 weeks, hearts were excised and then fixed for light and electron microscopy evaluation and tissue lipid peroxidation (malondialdehyde). Blood samples were also obtained for measuring plasma lipid peroxidation. RESULTS: Weight loss was observed in Group II, Group III, and Group IV. Weight loss was statistically significant in the DOX group. Findings of myocardial damage were significantly higher in animals treated with DOX only than in the control group. Histopathological findings of cardiotoxicity in rats treated with DOX in combination with L-NAME and L-NIL were not significantly different compared with the control group. The level of plasma malondialdehyde in the DOX group (9.3±3.4 µmol/L) was higher than those of all other groups. CONCLUSION: Our results showed that DOX cardiotoxicity was significantly decreased when DOX was given with NO synthase inhibitors.
ABSTRACT
OBJECTIVE: To study the effect of simvastatin on picrotoxin-induce seizures in mice in order to understand the impact of gabaergic system on neuronal cell death. METHODS: The study was held between July and September 2011, at the Karadeniz Technical University in Trabzon, Turkey. Balb/c mice weighting 20-40g were randomly selected and divided into five groups of six each. The first group was designated as control group; and the second as the picrotoxin (10mg/kg; intraperitoneal) alone group. The rest of the groups were administered simvastatin in dozes of 10, 20 and 40mg/kg respectively. Onset, number and duration of seizures, and death time were measured in mice for one hour. At the end of the study, the brain was removed from mice and normal and degenerative pyramidal neurons were counted in hippocampal CA1, CA2, CA3 region by light microscope. Using SPSS 17, Mann=Whitney U and Chi square and student-T tests were performed for statistical analysis. RESULTS: Simvastatin (10mg/kg) significantly decreased the number and duration of picrotoxin-induced seizures in mice. In addition, Simvastatin (10, 20, and 40mg/kg) significantly reduced the total number of abnormal pyramidal cells in CA1 and CA3 hippocampal regions compared to the picrotoxin-alone group. CONCLUSION: The effect of simvastatin on picrotoxin-induced seizures may be the result of increase in gabaergic activity and decrease in glutamatergic activity. More studies are needed to validate these results.

AIM: Cyclophosphamide (CP)-induced cystitis is a challenging clinical problem involving inflammation and dysfunction of bladder. Trimetazidine (TMZ) is an anti-anginal drug with anti-oxidant and anti-inflammatory properties. We aimed to investigate the protective effects of TMZ in CP-induced cystitis via inhibiting TLR4/NFκB signaling. MAIN METHODS: Balb/c mice were administrated TMZ (10 or 20 mg/kg/day) intraperitoneally (i.p.) for 5 consecutive days before CP. On day 6, cystitis was induced by a single dose of CP (300 mg/kg, i.p.). Mesna (2-mercaptoethane sulfonate sodium; 30 mg/kg, i.p.) was administered 20 min before and at 4 and 8 h after the CP injection. After 24 h of cystitis induction, the bladders were removed for histopathological evaluation, contractility studies, biochemical analysis and western blotting. MTT assay was performed in a cancer cell line (MDA-MB-231) to evaluate the effect of TMZ on the cytotoxicity of CP. KEY FINDINGS: CP-induced severe cystitis was confirmed by histological disturbances and the decrease in carbachol-evoked contractions of detrusor strips, which was partially improved by TMZ (20 mg/kg/day). SOD activity and GSH content were decreased whereas TNF-α and IL-1ß levels were increased in the bladders of CP-treated mice, which were restored by TMZ or mesna. TMZ reduced the CP-induced increase in the protein expressions of caspase-3, TLR4 and phosphorylated-NFκB in bladder tissues. TMZ alone decreased the cell viability and TMZ also enhanced the cytotoxicity of CP. SIGNIFICANCE: Our study provides the first preclinical evidence that TMZ attenuates CP-induced urotoxicity by enhancing anti-oxidant capacity and suppressing inflammation possibly via downregulating TLR4-mediated NFκB signaling while augmenting the cytotoxicity of CP.

The species belonging to Scrophularia genus grow mainly in Irano-Turanian and Mediterranean regions and have been used as folk remedy for inflammatory-related diseases since ancient times. The present study was aimed to evaluate the anti-inflammatory activity of the extracts of Scrophularia kotschyana as well as the isolated compounds. The aerial parts and the roots of the plant were separately extracted with methanol. Anti-inflammatory activities of both extracts were evaluated with formalin test in mice. As the methanolic extract of the aerial parts significantly (p < .05) inhibited inflammation, it was then submitted to successive solvent extractions with n-hexane, dichloromethane, ethyl acetate and n-butanol to yield subextracts. Anti-inflammatory activities of the subextracts were evaluated within the same test system. Among the subextracts tested, the n-butanol subextract produced a significant (p < .05) anti-inflammatory activity at all doses (5, 10, and 30 mg/kg, ip.). Sequential chromatographic separation of the n-butanol subextract yielded 8-O-acetyl-4'-O-(E)-p-coumaroylharpagide, 8-O-acetyl-4'-O-(Z)-p-coumaroylharpagide, ß-sitosterol 3-O-ß-glucopyranoside, apigenin 7-O-ß-glucopyranoside, apigenin 7-O-rutinoside, luteolin 7-O-ß-glucopyranoside and luteolin 7-O-rutinoside. The anti-inflammatory activities of the isolates were evaluated at 5 mg/kg dose. Luteolin 7-O-ß-glucopyranoside and apigenin 7-O-rutinoside caused a significant (p < .05) inhibition of oedema formation.

Cyclophosphamide (CP) is a widely used anti-neoplastic drug; however, it leads to bladder dysfunction in the form of hemorrhagic cystitis that is a serious dose-limiting complication in cancer patients. We aimed to evaluate the protective effects of metformin (MET) in a mouse model of CP-related cystitis in parallel with its effect on CP-induced cytotoxicity in a breast cancer cell line, MDA-MB-231. Cystitis was induced by a single intraperitoneal injection of CP (300 mg/kg), and mice were administered MET, mesna, or vehicle treatment. 24 hours after cystitis induction, the bladders were removed for histopathological analysis and ex vivo evaluation of detrusor muscle contractility. The effect of MET on the cytotoxicity of CP in MDA-MB-231 cells was evaluated as the viability of the cells via MTT assay. Histopathological evaluation confirmed that CP induced a severe cystitis, and MET partially inhibited CP-induced bladder damage. Carbachol-evoked cholinergic contractions were significantly decreased in detrusor strips of mice injected with CP only compared to control (Emax=293.67± 20.00 vs. 497.79± 21.78 mg tension/mg tissue, respectively). In CP-injected mice, treatment with 100 mg/kg MET restored cholinergic contractions (Emax=473.72±62.61 mg tension/mg tissue). In MDA-MB-231 cells, MET decreased their viability, and the combination of MET and CP caused more decrease in cell viability as compared to CP alone (p<0.05), demonstrating that MET enhances the cytotoxicity of CP in these cancer cells. Our results indicate that MET has a strong potential as a therapeutic adjuvant to prevent CP-induced cystitis while enhancing the efficacy of CP.

PURPOSE: Hemorrhagic cystitis (HC) is defined as any types of acute or chronic inflammation of urinary bladder with several reasons. One of the most common causes of HC is cyclophosphamide (CYP), an effective antineoplastic agent, due to its urotoxic potential. Ambroxol (AMB) is a mucoactive drug that has been used for numerous respiratory diseases. Besides its mucolytic activity, AMB is a potent antioxidant and antiinflammatory agent that is becoming more attractive for the treatment of several oxidative/inflammatory disorders. The aim of this study was to evaluate the uroprotective potential of AMB in CYP-induced HC. METHOD: Male Balb/c mice were pretreated with AMB (30, 70, and 100 mg/kg) once a day for 3 consecutive days before HC induction with CYP (300 mg/kg). Mesna (30 mg/kg;i.p.), only drug in the management of CYP-induced HC, was administered 20 min before; 4 and 8 h after cystitis induction. The urinary bladders were harvested and evaluated in functional, biochemical, and histological studies. RESULTS: CYP-induced HC markedly reduced acetylcholine (ACh)-induced contractions in detrusor strips and AMB at 100 mg/kg caused a significant increase in the responsiveness to ACh. Pretreatment with AMB prevented the elevation of malondialdehyde (MDA) and tumor necrosis factor-alpha (TNF-α) level, reduction of total glutathione (GSH) that induced by CYP. However, treatment with AMB did not improve the bladder weight and some histological parameters. CONCLUSION: These results suggest that AMB pretreatment could improve CYP-induced HC via antioxidant and antiinflammatory activities.

PURPOSE: Many studies have reported both a gender difference in the rates of depression and its treatment by using any of the widely used antidepressant drug groups. Some studies suggest that females respond more poorly to tricyclic antidepressants than males and appear to respond better to selective serotonin reuptake inhibitors (SSRI). There is no study investigating the analgesic/antinociceptive effects of antidepressant drugs on the basis of gender difference. In this study, we aimed to investigate the antinociceptive effect of paroxetine on the basis of gender difference. METHODS: The antinociceptive effect of paroxetine was tested using hot plate test in Balb/c mice (30-40 g). The animals were divided into eight groups on the basis of gender. FINDINGS: While paroxetine did not induce an antinociceptive effect in both sex at a dose of 1 mg kg(-1), it showed significant antinociceptive effects in both sex at a dose of 5 or 10 mg kg(-1). None of the doses of paroxetine revealed a gender difference in its antinociceptive action. CONCLUSION: There are several studies showing positive or negative evidence on the gender difference of paroxetine's antidepressant effect, but in the literature there is no study about the gender difference of paroxetine's or any other SSRI drug's antinociceptive effect. In conclusion, our results do not show any gender difference in antinociceptive effect of paroxetine that may be important especially when it would be used as an adjuvant agent in some painful conditions.

OBJECTIVES: Clinical and experimental trials have demonstrated that some of selective serotonin reuptake inhibitors (SSRIs) have some suspicious effects on blood glucose levels in different directions. Especially fluoxetine and sertraline are studied in this point of view. These drugs are also used in treatment of depression and peripheral neuropathy in diabetic patients. Paroxetine and fluoxetine, members of this drug group, besides having antidepressant effects were shown to have antinociceptive effects in animals and humans. They can be used in the treatment of chronic pain as an adjuvant drug or alone. But less is known about their actions on pain in case of diabetes. The aim of this study is to investigate the antinociceptive effects of fluoxetine and paroxetine in diabetic and non-diabetic mice while monitoring their effects on blood glucose levels. METHODS: Mice of either sex were randomly used in experiments. The antinociceptive effects of paroxetine and fluoxetine were evaluated using hot plate test both in diabetic and non-diabetic mice. The effects of these drugs on blood glucose levels were also evaluated in another group of mice both in diabetic and non-diabetic mice. RESULTS: Fluoxetine and paroxetine showed significant antinociceptive effect at all doses and at all times tested in non-diabetic mice, but they could not successfully show this effect in diabetic mice. They also had controversial effects on blood glucose levels. CONCLUSION: Although they showed increasing or decreasing effects on blood glucose levels in non-diabetic and diabetic mice, they showed antinociception on hot-plate test showing dissociation between blood glucose levels and analgesia.

OBJECTIVE: To investigate pregnancy outcomes following maternal use of pregabalin. METHODS: This multicenter, observational prospective cohort study compared pregnancy outcomes in women exposed to pregabalin with those of matched controls (not exposed to any medications known to be teratogenic or to any antiepileptic drugs). Teratology Information Services systematically collected data between 2004 and 2013. RESULTS: Data were collected from 164 exposed pregnancies and 656 controls. A significantly higher major birth defect rate in the pregabalin group was observed after exclusion of chromosomal aberration syndromes, and when cases with exposure during first trimester of pregnancy were analyzed separately (7/116 [6.0%] vs 12/580 [2.1%]; odds ratio 3.0, 95% confidence interval 1.2-7.9, p = 0.03). The rate of live births was lower in the pregabalin group (71.9% vs 85.2%, p < 0.001), primarily due to a higher rate of both elective (9.8% vs 5.0%, p = 0.02) and medically indicated (5.5% vs 1.8%, p = 0.008) pregnancy terminations. In the Cox proportional cause specific hazards model, pregabalin exposure was not associated with a significantly higher risk of spontaneous abortion. CONCLUSIONS: This study demonstrated a signal for increased risk of major birth defects after first trimester exposure to pregabalin. However, several limitations such as the small sample size, differences across groups in maternal conditions, and concomitant medication exposure exclude definitive conclusions, so these results call for confirmation through independent studies.

Psychotropic drug exposure during pregnancy is a common problem. Among the 601 cases exposed to drugs during pregnancy, who were followed by our Toxicology Information and Follow-up Service, 124 cases had used psychotropic drugs for depression, anxiety, or psychotic disorders. As the control group, 248 women, who did not use any drugs were selected. Of the 124 cases, 80 (64.5%) had healthy babies, and 17 (13.7%) decided to terminate the pregnancy. Spontaneous abortions, intrauterine death (in the 38th week) and premature deliveries were observed in the 9 (7.3%), 1 (0.8%) and 3 (2.4%) cases, respectively, in the drug exposure group. Pregnancies of the 14 (11.3%) cases were continuing during the preparation of this manuscript. Of the 248 controls, 151 (60.9%) had healthy babies, 9 (3.6%) experienced spontaneous abortion and 3 (1.2%) decided to terminate their pregnancies, 3 (1.2%) had premature deliveries, and we observed one (0.4%) congenital abnormality, 81 (32.7%) cases were still pregnant. Odds Ratio (95% confidence interval) for spontaneous abortion was found to be 1.35 (1.27-11.82) in the cases exposed to psychotropic drugs (P=0.02). No developmental problems were observed in the babies followed for 12 months. These data may give information about the early- but not the late-term effects of psychotropic drugs used in pregnant women.

AIM: Data about rosiglitazone use in pregnancy is limited. We aimed to present a pregnant woman who exposed to rosiglitazone in the second trimester and the fetal outcome. SUBJECT: The case was a 42-year-old, multigravid Caucasian woman with a history of diabetes mellitus type II for 4 years prior to her current pregnancy. Her diabetes was managed by diet and exercise and she has not received any drug therapy until the 13th week of her sixth (present) and unplanned pregnancy. The case was exposed to rosiglitazone (4 mg/day) between 13th and 17th gestational weeks. After the diagnosis of pregnancy at the 17th week, rosiglitazone was stopped and insulin therapy was started. At the 37th week, she had a healthy male infant (4500 g, 50 cm). The baby was examined and no major or minor malformations were observed. CONCLUSION: This is the first case present in the literature exposed to rosiglitazone in the second trimester of her pregnancy. The data from the present case may contribute to the existing limited knowledge about rosiglitazone in pregnancy.

PURPOSE: Little is known about the risks associated with prenatal exposure to atypical antipsychotics. Our objective is to present a case of exposure to risperidone and quetiapine in pregnancy, and additionally to some other drugs. CASE: Our case (36-year old) has suffered schizophrenia (DSM-IV) for 5 years and used these drugs (risperidone, quetiapine, mirtazapine, thioridazine, diazepam, hydroxyzine, clomipramine, fluvoxamine, alprazolam, carbamazepine, biperiden, haloperidol, ampicillin+sulbactam, enoxaparin, oxerutine) in her third pregnancy. Because of her psychotic condition, Mrs. N.B. was not aware of her pregnancy until 22nd week and the pregnancy could not be terminated. She had a female infant (3000 g, 50 cm) with APGAR scores of 8-9 at the first and fifth minutes at 37th week with an uncomplicated vaginal delivery. The baby was normal. CONCLUSION: This case may contribute to the existing knowledge regarding use of atypical antipsychotics in pregnancy.

Antidepressant drug choice in pregnancy is a complex problem especially for new drugs. Among 590 cases exposed to drugs during pregnancy who were followed by our center, 21 cases used newer antidepressants, i.e., venlafaxine, mirtazapine, nefazodone. We present the gestational findings and fetal outcomes of these cases. Ten cases had used venlafaxine, one case had used both venlafaxine and mirtazapine, eight had used mirtazapine alone or with some other drugs and two had used nefazodone, in the first trimester. Of the 21 cases, 17 (80.9%) had healthy babies, 3 (14.3%) decided to terminate the pregnancy, and 1 (4.8%) spontaneous abortion was observed in a case exposed to mirtazapine, alprazolam, diazepam and trifluoperazine. All obstetrical findings were normal during the pregnancy of each case. No congenital abnormality and developmental problem was observed in the babies followed up for 12 months. The aim of the present study is to contribute the data to the limited knowledge available in the literature regarding human pregnancy.

The subject is a diabetic and hypertensive woman treated early during an unplanned pregnancy with a multi-drug regimen that included three drugs with no prior history for use in pregnant women (rosiglitazone, gliclazide, atorvastatin). She was under care for chronic hypertension, which she suffered for 14 years, and diabetes mellitus, hypercholesterolemia, anxiety disorder, morbid obesity and epilepsia for 5 years. She was exposed to rosiglitazone (4mg/day), gliclazide (60mg/day), and atorvastatin (40mg/day) in addition to acarbose, spironolactone, hydrochlorothiazide, carbamazepine, thioridazine, amitryptiline, chlordiazepoxide, and pipenzolate bromide during the first 7 weeks of gestation while unaware of pregnancy. Pharmacotherapy was adjusted following clinical recognition of pregnancy during the 8th week. She gave birth to a normal healthy infant at the 36th week of gestation. This is the first reported case of human exposure to rosiglitazone, gliclazide, and atorvastatin during pregnancy. Although the normal pregnancy outcome does not address the safety of these drugs for use in pregnancy, these data contribute to a limited knowledge regarding human exposure to these antidiabetic drugs.

BACKGROUND: In this study, we aimed to investigate the possible effects of sertraline on blood glucose and lipid levels as risk factors for cardiovascular disease in depressive patients. METHODS: Eight male and twelve female depressive patients, diagnosed according to DSM-IV criteria, were included in this study. The subjects aged 19-50 years, did not smoke, and had normal body mass index (BMI), homeostasis model assessment-estimated insulin resistance (HOMA-IR) values, blood pressure, blood glucose, insulin and lipid levels. Sertraline therapy (50 mg/day) was started. Patients with diabetes mellitus, heart disease, pregnancy, and those taking other drugs were excluded from the study. Blood glucose, insulin, high-density lipoprotein-cholesterol (HDL-C), low-density lipoprotein-cholesterol (LDL-C), and triglyceride values were measured in patients before, and at the 4(th), 8(th) and 12(th) weeks after treatment with sertraline. Moreover, HbA1C levels were measured at the beginning and at the end of the treatment (at 12(th) weeks). RESULTS: There were no significant differences in physical examination (blood pressure, BMI, body weight, height, waist circumference) and laboratory findings (glucose, HDL-C, LDL-C, HOMA-IR and HbA1C levels) at the 12(th) week after of treatment with sertraline compared to pretreatment values. However, insulin levels at the 4(th), 8(th) and 12(th) weeks significantly increased compared with pretreatment values. Likewise, triglyceride levels at the 8(th) and 12(th) weeks significantly increased compared with pretreatment values. CONCLUSIONS: Sertraline-treated patients have to be followed up for blood insulin and triglyceride levels. In addition, their treatment plan needs to be adjusted as necessary to prevent possible metabolic changes.

Selective serotonin reuptake inhibitors are used in the treatment of psychiatric disorders but are associated with high incidence of sexual dysfunction such as ejaculation disorders by sertraline and fluoxetine, erection disorders by paroxetine. The aim of this study is to evaluate the effects of paroxetine, sertraline and fluoxetine on relaxation of smooth muscle of corpus cavernosum on the basis of nitric oxide (NO). Male mice were killed by cervical dislocation and their penile tissues were immediately removed. The tissues were incubated in organ baths containing Krebs solution at 37 degrees C and bubbled with 95% O(2) and 5% CO(2). The corpus cavernosum strips were contracted with 10(-5 )m phenylephrine (PHE) and relaxed with either paroxetine, sertraline, fluoxetine (10(-8)-10(-4 )m) or electrical field stimulation (EFS). The effects of paroxetine, sertraline and fluoxetine were examined on EFS-induced relaxations. While paroxetine did not show any effect on the corpus cavernosum strips precontracted with PHE, sertraline and fluoxetine caused a relaxation at concentrations of 3 x 10(-5)-10(-4 )m. The relaxations induced by sertraline and fluoxetine were completely abolished by L-NAME, but not D-NAME. The relaxations induced by EFS could be inhibited by L-NAME but not D-NAME. Paroxetine inhibited the relaxations at high concentrations. L-arginine potentiated the relaxations induced by EFS; however in the presence of paroxetine these relaxations were not observed. In contrast, sertraline (10(-8)-10(-5 )m) and fluoxetine (10(-8)-10(-5)m) increased the relaxations induced by EFS. Sertraline and fluoxetine seem to be releasing some relaxing factor(s) and this factor may be NO. Paroxetine probably has a NOS inhibitory activity either on nNOS or eNOS, in contrast to sertraline and fluoxetine.
