Remdesivir is an antiviral medication developed to treat COVID-19. It works by interfering with viral RNA polymerase, causing chain termination of the virus. While initially authorized to treat COVID-19, the WHO now recommends against its use due to trial results. Remdesivir is administered intravenously and can cause side effects like respiratory failure, organ impairment, and infusion site reactions.
Acyclovir is in a class of antiviral medications called synthetic nucleoside analogues. It works by stopping the spread of the herpes virus in the body.

NEW ORAL ANTIVIRAL FOR COVID 19
INVESTIGTIONAL ANTIVIRAL FOR COVID19
LAST UPDATE OF ANTIVIRAL COVID 19
Coronavirus disease (COVID-19) is an infectious disease caused by the SARS-CoV-2 virus.
Most people infected with the virus will experience mild to moderate respiratory illness and recover without requiring special treatment. However, some will become seriously ill and require medical attention. Older people and those with underlying medical conditions like cardiovascular disease, diabetes, chronic respiratory disease, or cancer are more likely to develop serious illness. Anyone can get sick with COVID-19 and become seriously ill or die at any age.
The best way to prevent and slow down transmission is to be well informed about the disease and how the virus spreads. Protect yourself and others from infection by staying at least 1 metre apart from others, wearing a properly fitted mask, and washing your hands or using an alcohol-based rub frequently. Get vaccinated when it’s your turn and follow local guidance.
The virus can spread from an infected person’s mouth or nose in small liquid particles when they cough, sneeze, speak, sing or breathe. These particles range from larger respiratory droplets to smaller aerosols. It is important to practice respiratory etiquette, for example by coughing into a flexed elbow, and to stay home and self-isolate until you recover if you feel unwell.
The Infection prevention and control in the context of coronavirus disease 2019 (COVID-19): a living guideline consolidates technical guidance developed and published during the COVID-19 pandemic into evidence-informed recommendations for infection prevention and control (IPC). This living guideline is available both online and PDF.
This version of the living guideline (version 6.0) includes fifteen statements on IPC measures in health-care settings (screening and patient placement, ventilation, physical barriers, environmental cleaning, waste management, amongst others) as well as one statement on mask fit in the community context.
Understanding the updated section
The update to this guideline considers the transition from critical emergency-response activities to longer-term, sustained COVID-19 disease prevention, control and management, and a shift towards integration of IPC activities into routine systems and practices. This includes a return to standard and transmission-based precautions in health-care settings, and the adoption of public health practices for community settings. Updated recommendations for health-care facilities include a focus on the hierarchy of control measures, source control, standard and transmission-based precautions. The prevention of health care-associated infections involves a multi-pronged and multi-factorial approach that includes infection prevention and control and occupational health and safety measures.

Treatment options for Corona Virus.pptxAwais irshad
Currently, only one medication has been approved to treat COVID-19. No cure is available for COVID-19. Antibiotics aren't effective against viral infections such as COVID-19. Researchers are testing a variety of possible treatments.
The FDA has approved the antiviral drug remdesivir (Veklury) to treat COVID-19 in hospitalized adults and children who are age 12 and older in the hospital. Remdesivir may be prescribed for people who are hospitalized with COVID-19 and need supplemental oxygen or have a higher risk of serious illness. It's given through a needle in the skin (intravenously).
The FDA has authorized a drug called Paxlovid that includes nirmatrelvir – a drug that blocks the activity of a specific enzyme needed for the virus that causes COVID-19 to replicate – and an antiviral drug called ritonavir that helps slow the breakdown of nirmatrelvir. Paxlovid is authorized to treat mild to moderate COVID-19 in people age 12 and older who are at higher risk of serious illness. The medications are taken by mouth as pills.
The FDA has authorized another drug called molnupiravir to treat mild to moderate COVID-19 in adults who are at higher risk of serious illness and who aren't able to take other treatment options. The medication is taken by mouth as a pill.
The FDA has authorized the rheumatoid arthritis drug baricitinib (Olumiant) to treat COVID-19 in some cases. Baricitinib is a pill that seems to work against COVID-19 by reducing inflammation and having antiviral activity. Baricitinib may be used in people who are hospitalized with COVID-19 who are on mechanical ventilators or need supplemental oxygen.
The U.S. National Institutes of Health has recommended the corticosteroid dexamethasone for people hospitalized with severe COVID-19 who are on supplemental oxygen or need mechanical ventilation. Other corticosteroids, such as prednisone, methylprednisolone or hydrocortisone, may be used if dexamethasone isn't available.
In some cases, the drugs remdesivir, tocilizumab or baricitinib may be given with dexamethasone in hospitalized people who are on mechanical ventilation or need supplemental oxygen.
The FDA has also authorized convalescent plasma therapy with high antibody levels to treat COVID-19. Convalescent plasma is blood donated by people who've recovered from COVID-19. Convalescent plasma with high antibodies may be used to treat some hospitalized people ill with COVID-19 who are either early in their illness or who have weakened immune systems.
Monoclonal antibodies aren't effective against treating COVID-19 caused by the omicron variant. These drugs were previously used to treat mild to moderate COVID-19 in people who had a higher risk of developing serious illness due to COVID-19.
Many people with COVID-19 may have mild illness and can be treated with supportive care. Supportive care is aimed at relieving symptoms and may include:
Pain relievers (ibuprofen or acetaminophen)
Cough syrup or medication
Rest
Fluid intake.
Vardif (Vardenafil HCl Oral Strips) is is a fast acting and highly effective medication with the same active ingredient Vardenafil HCl as Levitra. It starts working in less than 15 minutes after taking the dose and the medical effect will last for 3 to 4 hours.
This Protocol is adapted from the World Health Organization recommendations and reflects the current expert opinion of staff from Montefiore’s Antimicrobial Stewardship Program, Infectious Diseases Division, and Pharmacy. Clinical efficacies of these agents are still under investigation at this time. Treatments of COVID-19 are evolving as we gain more clinical experiences along with more published data. Supportive care remains the mainstay of treatment. The availability of certain agents may be limited due to supply chain disruptions and backorders. For suspected or confirmed cases requiring treatments listed below, please consult Infectious Diseases and notify Infection Prevention and Control Departments immediately.

CDSCO and Phamacovigilance {Regulatory body in India}NEHA GUPTA
The Central Drugs Standard Control Organization (CDSCO) is India's national regulatory body for pharmaceuticals and medical devices. Operating under the Directorate General of Health Services, Ministry of Health & Family Welfare, Government of India, the CDSCO is responsible for approving new drugs, conducting clinical trials, setting standards for drugs, controlling the quality of imported drugs, and coordinating the activities of State Drug Control Organizations by providing expert advice.
Pharmacovigilance, on the other hand, is the science and activities related to the detection, assessment, understanding, and prevention of adverse effects or any other drug-related problems. The primary aim of pharmacovigilance is to ensure the safety and efficacy of medicines, thereby protecting public health.
In India, pharmacovigilance activities are monitored by the Pharmacovigilance Programme of India (PvPI), which works closely with CDSCO to collect, analyze, and act upon data regarding adverse drug reactions (ADRs). Together, they play a critical role in ensuring that the benefits of drugs outweigh their risks, maintaining high standards of patient safety, and promoting the rational use of medicines.

Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

Remdesivir USED for COVID-19
[Process Development Scientist]
India
Remdesivir-COVID-19
Remdesivir, sold under the brand name Veklury, is a broad-spectrum antiviral medication
developed by the biopharmaceutical company Gilead Sciences. It is administered via
injection into a vein. During the COVID-19 pandemic, remdesivir was approved or
authorized for emergency use to treat COVID‑19 in around 50 countries. Updated
guidelines from the World Health Organization in November 2020 include a conditional
recommendation against the use of remdesivir for the treatment of COVID-19.
Remdesivir is a prodrug that is intended to allow intracellular delivery of GS-441524
monophosphate and subsequent biotransformation into GS-441524 triphosphate, a
ribonucleotide analogue inhibitor of viral RNA polymerase.
In November 2020, the World Health Organization (WHO) updated its guideline on
therapeutics for COVID-19 to include a conditional recommendation against the use of
remdesivir, triggered by results from the WHO Solidarity trial. The European Medicines
Agency announced that they will evaluate new data to see if a revision to the authorization
of remdesivir is needed.
In the European Union, remdesivir is indicated for the treatment of coronavirus disease
2019 (COVID‑19) in adults and adolescents (aged twelve years and older with body weight
at least 40 kilograms (88 lb)) with pneumonia requiring supplemental oxygen.
In the United States, remdesivir is indicated for use in adults and adolescents (aged twelve
years and older with body weight at least 40 kilograms (88 lb)) for the treatment of
2. April 25, 2021 Page 2
COVID‑19 requiring hospitalization. In November 2020, the FDA issued an emergency
use authorization (EUA) for the combination of baricitinib with remdesivir, for the
treatment of suspected or laboratory confirmed COVID-19 in hospitalized people two years
of age or older requiring supplemental oxygen, invasive mechanical ventilation, or
extracorporeal membrane oxygenation (ECMO).
How Should This Medicine Be Used
Remdesivir comes as a solution (liquid) and as a powder to be mixed with liquid and
infused (injected slowly) into a vein over 30 to 120 minutes by a doctor or nurse in a
hospital. It is usually given once daily for 5 to 10 days. The length of your treatment
depends on how well your body responds to the medication.
Remdesivir injection may cause serious reactions during and after the infusion of the
medication. A doctor or nurse will monitor you carefully while you are receiving the
medication. Tell your doctor or nurse immediately if you experience any of the following
symptoms during or after the infusion: chills or shivering; nausea; vomiting; sweating;
dizziness upon standing up; rash; wheezing or shortness of breath; abnormally fast or slow
heartbeat; or swelling of the face, throat, tongue, lips, or eyes. Your doctor may need to
slow down your infusion or stop your treatment if you experience these side effects.
The FDA has approved an Emergency Use Authorization (EUA) to allow children
weighing 8 pounds (3.5 kg) to less than 88 pounds (40 kg) or children less than 12 years of
age weighing at least 8 pounds (3.5 kg) who are hospitalized with severe COVID-19 to
receive remdesivir.
3. April 25, 2021 Page 3
Special Precautions- Before Receiving Remdesivir
1. Tell your doctor and pharmacist if you are allergic to remdesivir, any other
medications, or any of the ingredients in remdesivir injection. Ask your pharmacist
for a list of the ingredients.
2. Tell your doctor and pharmacist what other prescription and nonprescription
medications, vitamins, nutritional supplements, and herbal products you are taking
or plan to take. Be sure to mention any of the following: chloroquine or
hydroxychloroquine (Plaquenil). Your doctor may need to change the doses of your
medications or monitor you carefully for side effects.
3. Tell your doctor if you have or have ever had liver or kidney disease.
4. Tell your doctor if you are pregnant, plan to become pregnant, or are breastfeeding.
In Case Of Emergency/Overdose
In case of overdose, call the poison control helpline at 1-800-222-1222.
Information is also available online at https://www.poisonhelp.org/help
[https://www.poisonhelp.org/help]. If the victim has collapsed, had a seizure,
has trouble breathing, or can't be awakened, immediately call emergency
services at 911.
Brand Names: Veklury, GS-5734.

Mechanism Of Action
As an adenosine nucleoside triphosphate analog (GS-443902), the active metabolite of
remdesivir interferes with the action of viral RNA-dependent RNA polymerase and evades
proofreading by viral exoribonuclease (ExoN), causing a decrease in viral RNA
production. In some viruses such as the respiratory syncytial virus it causes the RNA-
dependent RNA polymerases to pause, but its predominant effect (as in Ebola) is to induce
an irreversible chain termination. Unlike with many other chain terminators, this is not
mediated by preventing addition of the immediately subsequent nucleotide, but is instead
delayed, occurring after five additional bases have been added to the growing RNA
chain.[36] For the RNA-Dependent RNA Polymerase of MERS-CoV, SARS-CoV-1, and
SARS-CoV-2 arrest of RNA synthesis occurs after incorporation of three additional
nucleotides. Hence, remdesivir is classified as a direct-acting antiviral agent that works as
a delayed chain terminator.
Interactions
Remdesivir is at least partially metabolized by the cytochrome P450 enzymes CYP2C8,
CYP2D6, and CYP3A4. Blood plasma concentrations of remdesivir are expected to
decrease if it is administered together with cytochrome P450 inducers such as rifampicin,
carbamazepine, phenobarbital, phenytoin, primidone. Using chloroquine or
hydroxychloroquine with remdesivir may reduce the antiviral activity of remdesivir.
Coadministration of remdesivir and chloroquine phosphate or hydroxychloroquine sulfate
is not recommended based on in vitro data demonstrating an antagonistic effect of
chloroquine on the intracellular metabolic activation and antiviral activity of remdesivir.
5. April 25, 2021 Page 5
Pharmacology
Remdesivir is a ProTide (Prodrug of nucleoTide). It is able to diffuse into cells where it is
converted to GS-441524 mono-phosphate via the actions of esterases (CES1 and CTSA)
and a phosphoamidase (HINT1); this in turn is further phosphorylated to its active
metabolite triphosphate by nucleoside-phosphate kinases. This pathway of bioactivation is
meant to occur intracellularly, but a substantial amount of remdesivir is prematurely
hydrolyzed in plasma, with GS-441524 being the major metabolite in plasma, and the only
metabolite remaining two hours after dosing.
Side Effects
The most common adverse effects in people treated with remdesivir were respiratory
failure and blood biomarkers of organ impairment, including low albumin, low potassium,
low count of red blood cells, low count of thrombocytes, and elevated bilirubin (jaundice).
Other reported adverse effects include gastrointestinal distress, elevated transaminase
levels in the blood (liver enzymes), infusion site reactions, and electrocardiogram
abnormalities. Remdesivir may cause infusion‐ related reactions, including low blood
pressure, nausea, vomiting, sweating or shivering.
