The outbreak of coronavirus disease 2019 (COVID-19) in December 2019 in China, has become a pandemic in March 2020. Repurposing old and relatively safe drugs becomes an advantageous option to obtain the urgently needed effective treatment. Repurposing chloroquine, hydroxychloroquine, oseltamivir, lopinavir/ritonavir, andfavipiravir, and the use of investigational drug remdesivir for treatment of COVID-19, are reviewed from the clinical pharmacology perspective, particularly its efficacy and safety. Limited clinical studies of chloroquine, hydroxychloroquine, favipiravir, and remdesivir showed some efficacy in COVID-19 treatment with tolerable adverse effects. Potential serious adverse effect of chloroquine and hydroxychloroquine is cardiac arrhythmia. Oseltamivir has no documented activity against SARS-CoV-2, while lopinavir/ritonavir showed limited efficacy in COVID-19. Currently, there is no sufficient evidence to recommend any specific anti-COVID-19 treatment. The decision to use these drugs during the COVID-19 pandemic must be based on careful consideration of the potential benefits and risks to the patient.

Objectives: To review the pharmacology, efficacy, and safety of Brexanolone and define its role in the treatment of postpartum depression. Date Sources: A MEDLINE/PubMed search was conducted (1980-May 2020) using the following keywords: postpartum depression, antidepressants, pharmacologic therapy, drug therapy, and brexanolone to identify relevant articles. Study Selection/Data Extraction: Literature search was limited to human studies published in the English language. Phase I, II, and III studies evaluating the pharmacology, efficacy, safety of brexanolone for postpartum depression were included. Bibliographies of relevant articles evaluating postpartum depression and treatment were reviewed for additional citations and background information. Data Synthesis: Brexanolone is a soluble, proprietary, injectable formulation of allopregnanolone, a neuroactive steroid that modulates neuronal excitability. Allopregnanolone levels increase during pregnancy and decrease substantially after birth. These fluctuations have profound effects on anxiety and depression. Three clinical trials established the efficacy and safety of brexanolone in the treatment of postpartum depression. In all 3 trials, brexanolone had an acceptable safety profile and was well tolerated. The most common adverse effects were loss of consciousness, sedation, dry mouth, headache, dizziness, and flushing. Due to sudden loss of consciousness and excessive sedation, continuous pulse oximetry is recommended. Conclusion: Brexanolone has a novel mechanism of action and appears to be safe and effective for the treatment of moderate to severe postpartum depression. At present, high cost, serious adverse effects, and restricted access may limit its use in clinical practice.

Lamotrigine, like all antiepileptic drugs, can be effective when used as monotherapy or adjunctive therapy. In general, adverse effects are reduced when monotherapy is employed. The most frequent adverse effect prompting withdrawal of lamotrigine is rash. This potentially life-threatening adverse effect occurs more frequently in children, is increased when a rapid dose titration schedule is employed, and is greater when lamotrigine is prescribed in combination with valproate. The availability of lamotrigine and other antiepileptic drugs represents a major advance for the treatment of childhood epilepsy. The challenge in using all of the new antiepileptic drugs, including lamotrigine, is to balance the expected improved efficacy with the potentially serious adverse effects.

Background: Coronavirus disease 2019 (COVID-19) is a new strain of coronavirus. It is characterized by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). It has quickly influenced all over the world since it spreads easily. Common symptoms are fever, cough, difficulty in breathing and muscle aches. Despite the urgent need to find an effective antiviral treatment, already available agents are being used alone or in combination all over the world. At the beginning of the pandemic, death rates of infection caused by COVID-19 are high but "is COVID-19 responsible for all deaths?", or “are there any contributions of the frequently used drugs in this period to these deaths?” Surely herd immunity plays a major role and has the contribution in the decline in mortality rates. Meanwhile, it is kept in mind that due to safety concerns, changes have also been made to the dosage and combined use of frequently used drugs. Objective: In this review, answers to two questions above and the safety of treatments, toxicities of agents involving chloroquine, hydroxychloroquine, remdesivir, favipiravir, lopiravir/ritonavir, sarilumab, tocilizumab, siltuximab, corticosteroids and bromhexine which are the most frequently used in both Turkey and all over the world will be summarized. Conclusion: Among these drugs favipiravir seems the most promising drug due to more tolerable adverse effects. More clinical trials with large sample sizes are needed to find the most effective and safe drug for COVID-19 treatment.

Objective. To perform a systematic evaluation of the efficacy and safety of combined treatment of Shenmai injection and chemotherapy for lung cancer. Methods. A literature search for randomized controlled trials (RCTs) describing the treatment of lung cancer by Shenmai injection and chemotherapy or chemotherapy alone was performed using the PubMed, Cochrane Library, China National Knowledge Infrastructure (CNKI), Value In Paper (VIP), China BioMed, and Wanfang databases. The databases were searched for entries published before September 1, 2019. Results. Thirty-seven RCTs, comprising a total of 2808 cases, were included in the present meta-analysis. Of these, 1428 cases were treated by Shenmai injection plus chemotherapy, and 1380 cases were treated only by chemotherapy. The results of meta-analysis showed that the combined treatment (Shenmai injection plus chemotherapy) increased the short-term efficacy of treatment (relative risk [RR] = 1.183, 95% confidence interval [CI] = 1.043–1.343, P < 0.01 ) and improved patients’ quality of life (RR = 1.514, 95%CI = 1.211–1.891, P < 0.01 ) compared with chemotherapy alone. With regard to the adverse effects, the combined treatment markedly reduced the incidence of white blood cell (WBC) reduction (RR = 0.846, 95%CI = 0.760–0.941, P < 0.01 ), platelet reduction (RR = 0.462, 95% CI = 0.330–0.649, P < 0.01 ), and hemoglobin reduction (RR = 0.462, 95% CI = 0.330–0.649, P < 0.01 ) and alleviated drug-induced liver injury (RR = 0.677, 95%CI = 0.463–0.990, P < 0.05 ). However, it did not offer a significant protective effect (RR = 0.725, 95%CI = 0.358–1.468, P < 0.05 ). The effect of the combined treatment on the occurrence of vomiting was considerable (RR = 0.889, 95%CI = 0.794–0.996, P < 0.05 ), and the combined treatment markedly increased the immunity of patients with lung cancer. Conclusion. The combined treatment of Shenmai injection plus chemotherapy enhanced the short-term efficacy of chemotherapy, improved the patient quality of life, alleviated the adverse effects of chemotherapeutics, and increased the patient immunity. These results should be confirmed by large-scale, high-quality RCTs.

Introduction: Rituximab is effective and safe treatment of immunobullous disorders. There are variations in doses of drugs used in different studies and uncertainties on when to use it along with use of adjuvant therapies. Efficacy and safety of this drug has not been described in Nepalese population till date. Dermatologists have hesitation in starting this drug in immunobullous diseases because of lack of data on efficacy and safety. Aim: To assess the efficacy and side effects of Rituximab therapy in treating immunobullous disorders in Nepalese patients. Materials and Methods: This was a retrospective study of patients with immunobullous diseases treated with Rituximab in Dermatological ward of Tribhuvan University Teaching Hospital, Kathmandu, Nepal from May 2018 to August 2019. Data were analysed for duration of disease and treatment received before Rituximab therapy, duration of steroid used before Rituximab, adverse effects due to prolonged steroid use, time to remission from 1st Rituximab pulse, duration of remission, relapse, duration of steroid and adjuvant drug used post 1st pulse and adverse effects associated with Rituximab. SPSS version 20 was used for data entry and descriptive statistics was used for analysis of the data. Results: Nine patients (Pemphigus Vulgaris-8 (PV-8), Bullous Pemphigoid-1 (BP-1) were treated with Rituximab. Seven were treated for refractory disease not controlled by conventional therapy and two received Rituximab as first-line therapy. The patients were under follow-up for 15-60 weeks (mean 31.89±15.62 weeks). Out of these nine patients, eight were free of lesions in one to eight weeks (mean 5.125±2 weeks) of first pulse. One patient with Oral Pemphigus had persistence of old lesions, however there were no new cutaneous lesions after first pulse. Adverse effects were seen in four patients that included infusion reaction in one and infection in three. There was relapse in one patient at last follow-up. Conclusion: Rituximab is efficacious and is safe in treating immunobullous disorders in Nepalese Population.

Background: Both salicylic acid (SA) and trichloroacetic acid (TCA) have proven efficacy with goodsafety profiles in the treatment of acne vulgaris. Objectives: This study compared the clinical efficacy and safety of 25% TCA and 30% SA peels in thetreatment of mild and moderate acne vulgaris. Methods: Patients with mild or moderate acne vulgaris were randomized into 2 groups of 25 personseach, and treated with either the TCA peel or the SA peel at 2-week intervals for 12 weeks. Evaluationof active acne was done by individual lesion counts (comedones, papules and pustules) and calculationof the Michaelsson acne score (MAS). Results: Both peels led to significant decrease in individual lesion counts and MAS compared to baselinevalues, without significant differences between the treatment groups. Thus, the peels had equivalentefficacy against acne vulgaris. The TCA peel was better in treating non-inflammatory lesions,while the SA peel was better for inflammatory lesions, but the differences were not significant. Noserious adverse effects were recorded, but more patients in the TCA peel group experienced burningand stinging sensations. Conclusion: The efficacy of 25% TCA is comparable to that of 30% SA in mild-to-moderate acnevulgaris, but safety and tolerability were better with the SA peel than TCA peel.

OBJECTIVE: To report three cases of possible foscarnet-induced neurologic sequelae. CASE SUMMARY: We report two cases of seizures and one case of hand cramping and finger paresthesia after starting foscarnet therapy with no evidence of predisposing risk factors, such as serum laboratory abnormalities, renal dysfunction, or known central nervous system (CNS) involvement. All three patients had stable laboratory values during therapy and when the neurologic adverse effects occurred. All patients were receiving appropriate dosages of foscarnet. DISCUSSION: The incidence of seizures in AIDS patients was reviewed. A history of CNS lesions, infections, and/or AIDS per se may increase the risk of a neurologic adverse effect while receiving foscarnet therapy. Acute ionized hypocalcemia may cause these neurologic adverse effects. Ionized hypocalcemia is transitory, is related to the rate of foscarnet infusion, and may not be reflected as a change in total serum calcium concentration. CONCLUSIONS: Foscarnet probably contributed to the neurologic adverse effects reported here. Foscarnet may need to be administered at a slower rate than is recommended by the manufacturer. Electrolytes must be monitored closely; however, a neurologic adverse effect may not be foreseen.
