Zidovir 50mg Syrup (Zidovudine)

Product Overview

Zidovir 50mg Syrup contains Zidovudine (AZT), a key ingredient that is a key component of antiretroviral treatment (ART) utilized for treatment and control of Human Immunodeficiency Virus (HIV) disease. Zidovudine is part of the class of medications that are known as nucleoside reverse transcription inhibitors (NRTIs). It acts by blocking reverse transcriptase, which is crucial to HIV replication. This results in a reduction of the amount of virus and enhances the performance of the immune system.

As oral syrup, Zidovir 50mg Syrup is particularly suitable for children, patients who are unable to swallow tablets, or when precise dose adjustments are needed.

Composition

• Active Ingredient: Zidovudine (ZDV) – 50 mg per 5 ml syrup
• Excipients: Sweeteners, flavoring agents, preservatives, stabilizers, and other inert ingredients
• Form: Oral syrup
• Packaging: Bottles with calibrated measuring device for accurate dosing

Indications

Zidovir 50mg Syrup is indicated for:

• Treatment for HIV-1-related infection both in children and adults in conjunction with antiretroviral treatment.
• Prevention of mother-to-child transmission (PMTCT) of HIV during pregnancy, labor, and breastfeeding.
• Post-exposure prophylaxis (PEP) in cases of accidental HIV exposure (in combination with other antiretroviral drugs).

Mechanism of Action

Zidovudine is a nucleoside synthetic analogue of thymidine. When it is infected with HIV, it’s phosphorylated and transformed into the active triphosphate version, zidovudine triphosphate (ZDV-TP), which competitively blocks the virus’s reverse transcriptase enzyme. The enzyme is crucial in the conversion of viral RNA to DNA — an essential stage in viral replication.

Inhibiting reverse transcriptase, Zidovudine blocks the synthesis of viral DNA, thus stopping the cycle of replication of HIV and decreasing the load of HIV.

Benefits of Zidovir 50mg Syrup

• Effective viral suppression: Significantly lowers HIV viral burden and reduces the rate of disease progression.
• Pediatric formulation: Syrup form allows for simple management and precise dosing for children and infants.
• Part of combination therapy: Together with other antiretroviral agents to stop drug resistance.
• Improves immune function: Aids in increasing CD4+ T-cell count, which boosts the immune system.
• Prevents mother-to-child transmission: Lowers the chance of HIV transmission by HIV-positive mothers to their infants.
• Well-studied: One of the very first antiretroviral medicines with a lot of scientific experience as well as safety information.

Dosage and Administration

Adults:

• The recommended dosage for adults can be 600 mg per day, which is given in the form of 300 mg daily, or 200 mg 3 times a day as part of a combination treatment.
• Syrup dosage should be adjusted to suit the needs.

Pediatrics:

• Dose calculations are usually by weight of the body or the area of your body.
• Children and infants, 10 to 15 mg/kg/day, divided into three or two dosages.
• The exact dose and timetable should be determined by your healthcare professional.

Administration Instructions:

• Shake the bottle thoroughly prior to every use to ensure correct mixing.
• Make use of the measuring instrument provided for administering the dose precisely.
• It can be consumed in combination with or without meals.
• Should be consumed regularly at the same time throughout the day to maximize effectiveness.

Side Effects

Zidovir is usually well tolerated; however, it may trigger some unwanted reactions, such as:

• Common Side Effects:
  • Headache
  • Nausea and vomiting
  • Fatigue and weakness
  • Loss of appetite
  • Muscle pain
  • Insomnia
• Serious Side Effects (Require Medical Attention):
  • Bone marrow dysfunction causes anemia and neutropenia (low white blood cell counts)
  • Lactic acidosis and severe hepatomegaly with steatosis (rare but serious)
  • Myopathy (muscle weakness)
  • Hypersensitivity reactions (rash, fever, swelling)
  • Peripheral neuropathy (numbness or tingling in hands/feet)

Monitoring of blood count and liver function is crucial when taking Zidovir.

Precautions and Warnings

• Bone marrow suppression: Keep track of blood counts frequently; adjustment or suspension of treatment could be needed in instances with severe neutropenia or anemia.
• Liver function: Avoid patients who have hepatic dysfunction; check the liver enzymes regularly.
• Lactic acidosis: Pay attention to symptoms such as stomach pain, fast breathing, or abnormal fatigue. Stop taking the drug in the event of suspicion.
• Pregnancy and breastfeeding: Zidovudine is the drug that can be used in PMTCT; however, it is best to use it under the guidance of a physician. It is recommended to avoid breastfeeding in mothers with HIV, unless directed otherwise.
• Drug interactions: Inform your physician of the medications you are taking and any supplements you may take because Zidovudine can interact with many drugs, which include antiretrovirals, antibiotics, and anticonvulsants.
• Adherence: A strict adherence to the dosing schedule is essential to prevent the development of resistance.

Storage

• Keep Zidovir syrup in the refrigerator between 20°C and 25°C (room temperature).
• Be sure to shield yourself from moisture and light.
• Close the bottle securely whenever not using it.
• Make sure that the area is safe for children.
