Bexovid Tablet 150 mg + 100 mg is an oral antiviral combination containing Nirmatrelvir and Ritonavir, indicated for the treatment of mild to moderate COVID-19 in adults and adolescents at high risk of progressing to severe disease. This combination works by inhibiting viral replication at an early stage, thereby reducing viral load, shortening disease duration, and lowering the risk of hospitalization and complications when used promptly after symptom onset.

Bexovid Tablet is designed for short-term treatment and should be initiated as soon as possible, ideally within the first few days of COVID-19 symptom appearance, as prescribed by a registered physician.

Therapeutic Class

Antiviral agent (SARS-CoV-2 protease inhibitor combination)

Composition

• Nirmatrelvir 150 mg

• Ritonavir 100 mg

Indications

Bexovid Tablet is indicated for:

• Treatment of mild to moderate COVID-19 infection

• Patients at high risk of developing severe COVID-19, including older adults and individuals with underlying medical conditions

• Early outpatient management of confirmed SARS-CoV-2 infection

It is not intended for the prevention of COVID-19 or for patients requiring hospitalization due to severe or critical disease.

Mechanism of Action

Nirmatrelvir is a selective inhibitor of the SARS-CoV-2 3CL protease, an enzyme essential for viral replication. By blocking this protease, Nirmatrelvir prevents the virus from processing polyproteins required for replication, effectively halting viral multiplication within host cells.

Ritonavir acts as a pharmacokinetic enhancer. It inhibits the CYP3A enzyme responsible for the metabolism of Nirmatrelvir, thereby increasing and prolonging its plasma concentration. Ritonavir itself does not have significant activity against SARS-CoV-2 but plays a crucial role in maintaining effective antiviral levels of Nirmatrelvir.

The combination ensures sustained antiviral action, leading to improved clinical outcomes when administered early in the course of infection.

Dosage and Administration

• For oral use only

• Dosage and treatment duration should be strictly followed as prescribed by a physician

• Typically taken for a short, fixed treatment course

• Tablets should be swallowed whole with or without food

Dose adjustment may be required in patients with renal or hepatic impairment.

Contraindications

Bexovid Tablet is contraindicated in:

• Patients with known hypersensitivity to Nirmatrelvir, Ritonavir, or any excipients

• Severe renal impairment or severe liver disease

• Concomitant use with certain medicines highly dependent on CYP3A for clearance, where elevated levels may cause serious adverse reactions

• Certain statins

• Immunosuppressants

A complete medication review should be conducted before initiating therapy.

Possible Side Effects

Common side effects may include:

• Altered taste sensation

• Diarrhea

• Nausea or vomiting

• Headache

• Abdominal discomfort

Most adverse effects are mild to moderate and resolve after completion of therapy.

Precautions and Warnings

• Not a substitute for COVID-19 vaccination

• Must be started early in the course of infection for maximum benefit

• Use with caution in patients with liver or kidney disease

• Patients should complete the full prescribed course even if symptoms improve

Use in Pregnancy and Lactation

Use during pregnancy and breastfeeding should be considered only if the potential benefit outweighs the risk and under medical supervision.

Storage Conditions

Conclusion

Bexovid Tablet 150 mg + 100 mg is an effective oral antiviral therapy for early COVID-19 management in high-risk patients. Its dual-action mechanism significantly reduces viral replication and helps prevent disease progression, making it a valuable option in outpatient COVID-19 treatment strategies.
