INTRODUCTION
Ketoprofen (K) was synthesized in 1968. K belongs to nonsteroidal anti-inflammatory drugs (NSAIDs) and has analgesic, anti-inflammatory and antipyretic properties. K is commonly used due to rapid absorption, simple metabolism, high antinociceptive activity and fast blood brain barrier crossing. However, this substance causes various side effects which are the major factors affecting its' popularity. Many researchers have modified this drug to discover an improved and safe NSAID.
AIM
The aim of the review was to find in recent publications data bout future prospects of K of improved safety for the gastric mucosa after oral administration.
METHOD
Systematic literature review was conducted in March 2021 (2015 onwards). We selected 22 articles from PubMed, Google Scholar, Medline Complete databases.
RESULTS AND DISCUSSION
Many studies aimed at obtaining K with lower ulcerogenic properties. This article describes K with lysine, new K delivery systems, K in form of hydrogels, prodrugs and codrugs of K, K as ATB-352, K with zinc, K encapsulated as proliposomal powders and several substances that reduce the gastric side effects of K described after 2015.
CONCLUSION
Our review confirms that modifications of K maintain its' desirable actions and decrease ulcer producing side effect. Some new forms of K were also found to have better activity profile compared to the parent drug.

In March 2020, the World Health Organization declared the spread of SARS-CoV-2 a global pandemic. To date, coronavirus disease-2019 (COVID-19) has spread to over 200 countries, leading to over 1.6 million cases and over 99,000 deaths. Given that there is neither a vaccine nor proven treatment for COVID-19, there is currently an urgent need for effective pharmacotherapy. To address the need for an effective treatment of SARS-CoV-2 during the worldwide pandemic, this systematic review of intravenous (IV) remdesivir was performed. Remdesivir, an anti-viral prodrug originally developed to treat Ebola virus disease, has shown broad spectrum activity against the Coronavirus family. A recent case report reported improvement of clinical symptoms with remdesivir in a patient with COVID-19. After conducting a systematic search of 18 clinical trial registries and three large scientific databases, we identified 86 potentially eligible items. Following removal of duplicates (n = 21), eligible studies were reviewed independently by two authors. After the first round of screening, inter-rater agreement was 98.5% (κ = 0.925). After the second round of full-text screening, inter-rater agreement was 100%. A total of seven ongoing and recruiting clinical trials of remdesivir (100-200 milligrams, intravenous [IV]) were included. We identified the following primary outcomes: patients discharged (n = 2); time to clinical status improvement (n = 2); improved O2 saturation (n = 2); body temperature normalization (n = 2); and clinical status (n = 1). Secondary outcomes in all identified studies included documentation of adverse events. Phase 3 trials are expected to be completed between April 2020-2023. Therefore, despite supportive data from in vitro and in vivo studies, the clinical effectiveness of IV remdesivir for treatment of COVID-19 and potential side effects remain incompletely defined in the human population.

The rising outbreak of SARS-CoV-2 continues to unfold all over the world. The development of novel effective antiviral drugs to fight against SARS-CoV-2 is a time cost. As a result, some specific FDA-approved drugs have already been repurposed and authorized for COVID-19 treatment. The repurposed drugs used were either antiviral or non-antiviral drugs. Accordingly, the present review thoroughly focuses on the repurposing efficacy of these drugs including clinical trials experienced, the combination therapies used, the novel methods followed for treatment, and their future perspective. Therefore, drug repurposing was regarded as an effective avenue for COVID-19 treatment. Recently, molnupiravir is a prodrug antiviral medication that was approved in the United Kingdom in November 2021 for the treatment of COVID-19. On the other hand, PF-07321332 is an oral antiviral drug developed by Pfizer. For the treatment of COVID-19, the PF-07321332/ritonavir combination medication is used in Phase III studies and was marketed as Paxlovid. Herein, we represented the almost history of combating COVID-19 from repurposing to the recently available oral anti-SARS-CoV-2 candidates, as a new hope to end the current pandemic.

INTRODUCTION
The number of diseases covered by universal neonatal screening in Germany has risen steadily from 1 (phenylketonuria) in 1968 to 17 (with hearing impairment and congenital hip dysplasia) in 2018. Treatment, however, of disorders diagnosed by screening may harm children, as failed neuroblastoma screening has shown. There are several pilot studies to detect congenital cytomegalovirus (CMV) infection but no consensus as to the treatment of the infants identified.
METHODOLOGY
Systematic search for studies investigating therapy of congenital CMV infection, using PubMed and the WHO International Clinical Trials Registry Platform (ICTRP).
RESULTS
We found only one controlled trial that randomized infants with symptomatic congenital CMV infection (involving the central nervous system) to treatment (intravenous ganciclovir for 6 weeks) or no treatment. Treatment was associated with significantly less hearing deterioration. A second trial comparing 6 weeks vs. 6 months of treatment with valganciclovir, an oral prodrug of ganciclovir, found no benefit for hearing but modestly improved developmental outcomes associated with 6 months of treatment. In contrast, an open-label registry reported benefits for infants with congenital CMV infection and isolated hearing who received valganciclovir for 12 months, with hearing improvement in 2/3 of cases after a median follow-up of 4½ years.
CONCLUSIONS
Antiviral treatment of neonates with congenital CMV infection and few symptoms including isolated hearing loss remains controversial. A generally accepted therapy, however, is pivotal before introducing universal or targeted screening for congenital CMV infection.
