Insights
Current COVID-19 treatments are supportive. While remdesivir may hasten recovery, no drug has proven effective in peer-reviewed trials for treating or preventing coronavirus disease 2019 (COVID-19).
Area of Science:
- Virology
- Infectious Diseases
- Pharmacology
Background:
- The emergence of novel coronavirus disease 2019 (COVID-19), caused by SARS-CoV-2, has led to a global pandemic.
- Current management strategies for COVID-19 are primarily supportive.
- Numerous clinical trials are investigating existing and novel agents for COVID-19 treatment and prevention.
Purpose of the Study:
- To provide an overview of pharmacological agents and therapies under investigation for COVID-19.
- To discuss potential treatment options and adjunctive agents for infected patients.
- To explore agents for chemoprophylaxis in preventing COVID-19 infection.
Main Methods:
- Review of ongoing clinical trials and investigational agents for COVID-19.
- Analysis of pharmacological therapies being evaluated for treatment and prevention.
- Assessment of current evidence for treatment efficacy.
Main Results:
- At the time of writing, no peer-reviewed randomized clinical trial data demonstrate improved outcomes with any pharmacological agent for COVID-19.
- Remdesivir, an investigational antiviral, has been reported to hasten clinical recovery, pending peer-reviewed publication.
Conclusions:
- No definitive pharmacological treatments are currently established for COVID-19 based on robust clinical trial evidence.
- Further research and peer-reviewed data are crucial to establish effective treatments and preventive strategies for COVID-19.
- Investigational agents like remdesivir show potential but require further validation.
Abstract:
A novel coronavirus disease 2019 (COVID-19) infection caused by severe acute respiratory syndrome coronavirus 2 (SARS-Cov-2) first emerged in December 2019 in Wuhan, China, has become a global pandemic. Currently, the management of COVID-19 infection is mainly supportive. Several clinical trials worldwide are evaluating several drugs approved for other indications, as well as multiple investigational agents for the treatment and prevention of COVID-19. Here, we give a brief overview of pharmacological agents and other therapies which are under investigation as treatment options or adjunctive agents for patients infected with COVID-19 and for chemoprophylaxis for the prevention of COVID-19 infection. At the time of writing this commentary, there is no peer-reviewed published evidence from randomized clinical trials of any pharmacological agents improving outcomes in COVID-19 patients. However, it was reported that remdesivir an investigational antiviral agent hastens clinical recovery, but a study is yet to be published in peer-reviewed medical journal.

Targets for Drug Action: Overview
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...
Principles of Drug Action
Drugs can be agonists or antagonists. Like the endogenous ligands, agonists always bind and activate the target to produce a cellular response. Agonist binding induces a conformational change which in turn...

Sedatives and Hypnotics Drugs: Miscellaneous Agents
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
