Introduction: Erectile dysfunction is among the most prevalent urologic issues affecting men globally and is characterized by a high incidence rate. This condition significantly affects the quality of life of patients and their sexual partners., Objectives: Due to the interactions, contraindications, and side effects associated with systemic drugs, recent research has increasingly focused on topical and transdermal medications for the treatment of erectile dysfunction., Methods: Based on previous studies, this article examines papaverine in terms of local effectiveness, methods of increasing therapeutic efficiency, possible local side effects, and evaluation of its various formulations., Results: Among these approaches, notable strategies include using novel formulations and nanoformulations as compared with classic ones, employing permeation enhancers, and combining treatments with other oral and topical drugs with synergistic mechanisms. These methods aim to improve transdermal papaverine's bioavailability and therapeutic efficacy while minimizing side effects and enhancing patient compliance., Conclusion: Transdermal papaverine may not be as effective as its injectable form, but the treatment path is more pleasant, with less pain and fewer side effects for patients. For this reason, using solutions that remove the penile skin and fascial absorption barrier can be very effective., (© The Author(s) 2024.

Introduction: Due to the prevalence of erectile dysfunction and impotence among men in recent years, several pharmacotherapies have been considered for such problems. Systemic drug therapies in the treatment of erectile dysfunction have significant issues, including drug interactions and contraindications in a wide range of diseases, which makes researchers seek to design drugs and dosage forms with fewer side effects, interactions, and contraindications with maintained efficacy., Objectives: 5-Phosphodiesterase inhibitors (5-PDEIs or PDE5Is), previously used systemically to treat erectile malfunction, are now appropriate candidates for topical application with considerable potency and fewer complications., Methods: We sought to investigate the recent findings on the current subject in order to provide a comprehensive overview of the issue using an extensive literature search to pinpoint the latest scientific reports on this subject., Results: In the present review, the function of 5-Phosphodiesterase inhibitors as topical formulations was evaluated with details including formulation type, adsorption, and comparative efficacy in all recent studies as an acceptable alternative therapy to systemic drugs., Conclusions: Due to the fact that the influential factors in erectile dysfunction interact with many diseases and delinquent treatments, the use of topical therapeutic agents can be promising in mild to moderate cases. The utilization of 5-PDEIs through novel topical and transdermal drug delivery techniques plays a vital role in improving this effectiveness. Hamzehnejadi M, Tavakoli MR, Abiri A, et al.

In December 2019, a cluster of pneumonia caused by a novel coronavirus (2019-nCoV), officially known as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), emerged in Wuhan, Hubei province, China. Cytokine storm is an uncontrolled systemic inflammatory response resulting from the release of large amounts of pro-inflammatory cytokines and chemokines that occurs at phase 3 of viral infection. Such emergence led to the development of many clinical trials to discover efficient drugs and therapeutic protocols to fight with this single-stranded RNA virus. Corticosteroids suppress inflammation of the lungs during the cytokine storm, weaken immune responses, and inhibit the elimination of pathogen. For this reason, in COVID-19 corticosteroid therapy, systemic inhibition of inflammation is observed with a wide range of side effects. The present review discusses the effectiveness of the corticosteroid application in COVID-19 infection and the related side effects of these agents. In summary, a number of corticosteroids, including and especially methylprednisolone and dexamethasone, have demonstrated remarkable efficacy, particularly for COVID-19 patients who underwent mechanical ventilation., (Copyright © 2021 Langarizadeh et al.)
