Review
This meta-analysis was conducted to assess the effectiveness of topical anesthetics in preventing premature ejaculation. We conducted an online database search for original studies comparing topical anesthetic agents with placebo in patients with premature ejaculation. After selecting relevant articles, we extracted data on baseline characteristics and predetermined endpoints. Intravaginal ejaculatory latency time (IELT) was the primary outcome for efficacy. Mean differences and corresponding 95% confidence intervals were used to present continuous data. A random-effects model was used to pool the data, and subgroup analysis was performed based on the type of anesthetic agent used. Eleven randomized controlled trials were examined, involving a total of 2008 participants. After analyzing the combined results, it was found that Severance Secret (SS) cream (CJ CheilJedang Corporation, Seoul, South Korea) demonstrated significantly higher effectiveness than a placebo in increasing IELT (P = 0.001). Similarly, the topical eutectic mixture for premature ejaculation (TEMPE), lidocaine, and the eutectic mixture of local anesthetics (EMLA) were significantly more efficient than a placebo (P<0.00001; P = 0.0001; P<0.00001). Additionally, it was found that lidocaine gel was more efficient than paroxetine or sildenafil (P = 0.04; P<0.00001). In conclusion, topical anesthetics increase IELT in men with premature ejaculation more effectively than placebo, sildenafil, tadalafil, paroxetine, and dapoxetine.

Observational Study
BACKGROUND
Consensus-guidelines for prescribing antidepressants recommend that clinicians should be vigilant to match antidepressants to patient's medical history but provide no specific advice on which antidepressant is best for a given medical history.
AIMS OF THE STUDY
For patients with major depression who are in psychotherapy, this study provides an empirically derived guideline for prescribing antidepressant medications that fit patients' medical history.
METHODS
This retrospective, observational, cohort study analyzed a large insurance database of 3,678,082 patients. Data was obtained from healthcare providers in the U.S. between January 1, 2001, and December 31, 2018. These patients had 10,221,145 episodes of antidepressant treatments. This study reports the remission rates for the 14 most commonly prescribed single antidepressants (amitriptyline, bupropion, citalopram, desvenlafaxine, doxepin, duloxetine, escitalopram, fluoxetine, mirtazapine, nortriptyline, paroxetine, sertraline, trazodone, and venlafaxine) and a category named "Other" (other antidepressants/combination of antidepressants). The study used robust LASSO regressions to identify factors that affected remission rate and clinicians' selection of antidepressants. The selection bias in observational data was removed through stratification. We organized the data into 16,770 subgroups, of at least 100 cases, using the combination of the largest factors that affected remission and selection bias. This paper reports on 2,467 subgroups of patients who had received psychotherapy.
RESULTS
We found large, and statistically significant, differences in remission rates within subgroups of patients. Remission rates for sertraline ranged from 4.5% to 77.86%, for fluoxetine from 2.86% to 77.78%, for venlafaxine from 5.07% to 76.44%, for bupropion from 0.5% to 64.63%, for desvenlafaxine from 1.59% to 75%, for duloxetine from 3.77% to 75%, for paroxetine from 6.48% to 68.79%, for escitalopram from 1.85% to 65%, and for citalopram from 4.67% to 76.23%. Clearly these medications are ideal for patients in some subgroups but not others. If patients are matched to the subgroups, clinicians can prescribe the medication that works best in the subgroup. Some medications (amitriptyline, doxepin, nortriptyline, and trazodone) always had remission rates below 11% and therefore were not suitable as single antidepressant therapy for any of the subgroups.
DISCUSSIONS
This study provides an opportunity for clinicians to identify an optimal antidepressant for their patients, before they engage in repeated trials of antidepressants.
IMPLICATIONS FOR HEALTH CARE PROVISION AND USE
To facilitate the matching of patients to the most effective antidepressants, this study provides access to a free, non-commercial, decision aid at http://MeAgainMeds.com.
IMPLICATIONS FOR HEALTH POLICIES
Policymakers should evaluate how study findings can be made available through fragmented electronic health records at point-of-care. Alternatively, policymakers can put in place an AI system that recommends antidepressants to patients online, at home, and encourages them to bring the recommendation to their clinicians at their next visit.
IMPLICATIONS FOR FURTHER RESEARCH
Future research could investigate (i) the effectiveness of our recommendations in changing clinical practice, (ii) increasing remission of depression symptoms, and (iii) reducing cost of care. These studies need to be prospective but pragmatic. It is unlikely random clinical trials can address the large number of factors that affect remission.

Adenosine (ADO) is an extracellular signaling molecule generated locally under conditions that produce ischemia, hypoxia, or inflammation. It is involved in modulating a range of physiological functions throughout the brain and periphery through the membrane-bound G protein-coupled receptors, called adenosine receptors (ARs) AAR, AAR, AAR, and AAR. These are therefore important targets for neurological, cardiovascular, inflammatory, and autoimmune diseases and are the subject of drug development directed toward the cyclic adenosine monophosphate and other signaling pathways. Initially using public data for AAR agonists we generated and validated a Bayesian machine learning model (Receiver Operator Characteristic of 0.87) that we used to identify molecules for testing. Three selected molecules, crisaborole, febuxostat and paroxetine, showed initial activity using the HEK293 AAR Nomad cell line. However, radioligand binding, β-arrestin assay and calcium influx assay did not confirm this AAR activity. Nevertheless, several other AR activities were identified. Febuxostat and paroxetine both inhibited orthosteric radioligand binding in the µM range for AAR and AAR. In HEK293 cells expressing the human AAR, stimulation of cAMP was observed for crisaborole (EC 2.8 µM) and paroxetine (EC 14 µM), but not for febuxostat. Crisaborole also increased cAMP accumulation in AAR-expressing HEK293 cells, but it was weaker than at the AAR. At the human AAR, paroxetine did not show any agonist activity at 100 µM, although it displayed binding with a K value of 14.5 µM, suggesting antagonist activity. We have now identified novel modulators of AAR, AAR and AAR subtypes that are clinically used for other therapeutic indications, and which are structurally distinct from previously reported tool compounds or drugs.

OBJECTIVE
It is known that selective serotonin reuptake inhibitors (SSRIs), represent an important and effective treatment of depression and other psychological disorders, these medications can increase prolactin levels mainly through activation of the serotonergic pathway. In this study, we aimed to determine the beneficial effects of irisin on paroxetine, a SSRI, induced hyperprolectinemia and in some other reproductive hormonal changes associated with hyperprolactinemia.
METHODS
Thirty two male Spraque-Dawley rats were used and divided into four groups including sham-operated control (vehicle), irisin (100 ng/kg/day for 28 days with mini-osmotic pumps), paroxetine (treated with 20 mg/kg paroxetine by oral gavage), irisin and paroxetine+irisin groups (n = 8). Serum prolactin (PRL), kisspeptin, luteinizing hormone (LH), follicle-stimulating hormone (FSH), testosterone and 5-alpha reductase levels were determined with enzyme-linked immunosorbent analysis (ELISA).
RESULTS
In animals treated with paroxetine, PRL level increased and testosterone level decreased significantly (p < 0.05). Serum LH level was significantly increased in the group, but no significant changes were observed in the FSH, kisspeptin and 5-alpha reductase levels. Serum prolactin levels was significantly decreased in the group treated with irisin. While no significant difference was observed in kisspeptin, FSH and 5-alpha reductase levels, an increase in serum LH and testosterone levels with irisin administration (p < 0.05).
CONCLUSION
In conclusion, chronic irisin exposure may reverse paroxetine-induced hyperprolactinemia. These results indicate that irisin may have the potential to be used as a therapeutic agent by primarily affecting paroxetine-induced increased prolactin and decreased testosterone levels.

OBJECTIVE
Premature ejaculation (PE) and erectile dysfunction (ED) are sexual dysfunction diseases affecting males. The phosphodiesterase type 5 (PDE5) inhibitors such as tadalafil are used to treat ED whereas selective serotonin reuptake inhibitors (SSRIs) are preferred for PE. Most of the patients with ED also suffer from PE simultaneously. The combined drug therapies are commonly preferred as they favor elevated intra-vaginal ejaculation latency time (IELT) scores and improved sexual function. The study aimed to evaluate the efficacy and safety of daily paroxetine and tadalafil combination therapy in patients with PE and ED.
PATIENTS AND METHODS
A total of 81 PE patients with ED were enrolled in the study. Patients were treated with daily paroxetine 20 mg and tadalafil 5 mg for 4 weeks. Pre- and post-treatment IELT, premature ejaculation profile (PEP), and International Index of Erectile Function-Erectile Function (IIEF-EF) scores of the patients were analyzed.
RESULTS
The mean IELT and PEP index scores, and mean IIEF-EF values improved after combination therapy (p<0.001 for each). When lifelong and acquired PE+ED patients were compared, significant improvements were observed in IELT, PEP, and IIEF-EF scores in both groups (p<0.001).
CONCLUSIONS
Even though the treatment methods are different, combined therapies to treat simultaneous PE and ED presence are effective compared to monotherapies. However, there is still no definitive treatment that can cure all subtypes of PE or ED.

Selective serotonin reuptake inhibitors (SSRIs), serotonin and noradrenaline reuptake inhibitors (SNRIs), and noradrenergic and specific serotonergic antidepressants (NaSSAs) are broadly used for the treatment of depression. Depression is one of the most common psychiatric disorders in pregnant women and SSRIs are commonly prescribed for depression during pregnancy. The placenta regulates the transport of nutrients and oxygen between the maternal and fetal circulation, and is essential for the survival and growth of the fetus. The present study investigated the effects of antidepressants on human placental BeWo cells. BeWo cell viability was significantly decreased following exposure to sertraline (SSRI), paroxetine (SSRI), fluvoxamine (SSRI), and duloxetine (SNRI), whereas escitalopram (SSRI), venlafaxine (SNRI), and mirtazapine (NaSSA) showed little or no effects. Extracellular lactate dehydrogenase activity was increased by sertraline, paroxetine, fluvoxamine, and duloxetine, indicating toxicity to the cells. Sertraline increased the production of cellular reactive oxygen species (ROS) and decreased the mitochondrial membrane potential. Sertraline decreased the cellular ATP content in a time and concentration-dependent manner. Caspase-3/7 activity and apoptotic cells, detected using the phosphatidylserine-specific fluorescent probe Apotracker Green, were increased by sertraline. Our findings suggest that antidepressants, such as sertraline, paroxetine, fluvoxamine, and duloxetine, induce toxicity in human placental BeWo cells. Sertraline may induce ROS-dependent apoptosis in human placental cells. These results are useful for further studies to determine the optimal dosage of antidepressants for pregnant women.

Review
Most women experience vasomotor symptoms (VMS) during their menopausal transition. Menopausal hormone therapy (HT) is the most effective treatment for VMS, but some women choose not to use HT or have contraindications to using HT. Non-hormonal treatment options should be offered to these symptomatic menopausal women. Multiple large randomized controlled trials have demonstrated statistically significant reductions in hot flash severity and/or frequency with the use of selective serotonin reuptake inhibitors (SSRIs) and serotonin norepinephrine reuptake inhibitors (SNRIs). To date, paroxetine mesylate remains the only non-hormonal treatment that has been approved by the United States Food and Drug Administration (FDA) for the management of moderate to severe postmenopausal vasomotor symptoms. Lower doses are needed to reduce VMS than those used to treat anxiety or depression, which is beneficial since side effects are typically dose dependent. The recommended dosage is 7.5 mg once daily at bedtime. Dose dependent side effects include nausea, fatigue, and dizziness. Knowing potential medication interactions is critical such as with medications that can lead to serotonin syndrome, concomitant use with monoamine oxidase inhibitors and being aware of p450 drug metabolism is essential for patients taking drugs that utilize the CYP2D6 enzyme for metabolism including tamoxifen. This review discusses in detail the available data supporting the use of paroxetine for the treatment of VMS, including side effects and considerations regarding prescribing. A discussion of other emerging treatments is included as well, including estetrol, oxybutynin and neurokinin 3 (NK3) receptor antagonists.

Review
Post-traumatic stress disorder (PTSD) is a disabling psychiatric condition with a critical familiar, personal, and social impact. Patients diagnosed with PTSD show various symptoms, including anxiety, depression, psychotic episodes, and sleep disturbances, complicating their therapeutic management. Only sertraline and paroxetine, two selective serotonin reuptake inhibitors, are approved by different international agencies to treat PTSD. In addition, these drugs are generally combined with psychotherapy to achieve positive results. However, these pharmacological strategies present limited efficacy. Nearly half of the PTSD patients do not experience remission of symptoms, possibly due to the high prevalence of psychiatric comorbidities. Therefore, in clinical practice, other off-label medications are common, even though the effectiveness of these drugs needs to be further investigated. In this line, antipsychotics, antiepileptics, adrenergic blockers, benzodiazepines, and other emerging pharmacological agents have aroused interest as potential therapeutic tools to improve some specific symptoms of PTSD. Thus, this review is focused on the most widely used drugs for the pharmacological treatment of PTSD with a translational approach, including clinical and preclinical studies, to emphasize the need to develop safer and more effective medications.

OBJECTIVES
This study aimed to investigate the plasma and breastmilk concentrations for sertraline, citalopram and paroxetine for assessment of the Milk/Plasma (M/P) ratio and Absolute Infant Dose (AID), and to determine actual infant drug exposure through breastfeeding. Subsequently, informed recommendations will be formulated regarding the advisability of breastfeeding in women undergoing treatment with the three most widely used antidepressants.
METHODS
A pharmacokinetic study in lactating women and their infants using sertraline, citalopram or paroxetine was performed. Paired breastmilk and plasma samples and single point infant plasma samples were collected to determine antidepressant concentrations. An Area Under the Curve (AUC) based approach with the trapezoidal rule was used to calculate M/P ratios and AID for all three antidepressants by combining all measured concentrations for the same dose.
RESULTS
Thirty-seven lactating women and their infants participated in this study. 111 paired breastmilk and plasma samples and 37 single point infant plasma samples were collected. Detectable concentrations of sertraline, citalopram and paroxetine were present in all breastmilk samples. For sertraline and citalopram M/P ratio is above one, indicating higher breastmilk than plasma concentrations, however, drug exposure by breastmilk did not lead to detectable plasma drug levels in any of the 15 infants for sertraline, for nine (out of 13) infants for citalopram and for eight (out of nine) infants for paroxetine.
CONCLUSION
Given the well-known benefits of breastfeeding, our findings support breastfeeding of infants by mothers who are taking sertraline, citalopram or paroxetine is safe. Sertraline and paroxetine are the preferred antidepressants during breastfeeding, reaching mostly undetectable infant drug levels.
