Introduction of  Artesunate 


Artesunate is a water-soluble hemisuccinate derivative of artemisinin. It is unstable in a neutral solution and the injectable formulation must be prepared immediately before use in 5% (w/v) sodium bicarbonate solution to produce the salt sodium artesunate. After parenteral administration, it is rapidly hydrolyzed to the active metabolite dihydroartemisinin. The oral formulation is probably hydrolyzed completely before entering the systemic circulation. Artesunate has been reported to clear fever in patients with severe falciparum malaria 16-25 hours after parenteral administration. Artesunate tablets are a pharmaceutical formulation that contains the active ingredient artesunate, which belongs to the artemisinin class of antimalarial drugs. Artemisinin-based combination therapies (ACTs), such as those containing artesunate, are widely used for the treatment of malaria, a life-threatening parasitic infection transmitted through the bites of infected mosquitoes.

Here is a brief introduction to key aspects of Artesunate tablets:

1. Active Ingredient:

Artesunate is a derivative of artemisinin, a compound extracted from the sweet wormwood plant (Artemisia annua). Artemisinin and its derivatives are known for their potent antimalarial properties.

2. Antimalarial Action:

Artesunate is highly effective against the Plasmodium parasites responsible for causing malaria, including Plasmodium falciparum, which is the most deadly species. The drug works by disrupting the parasites' life cycle within red blood cells.

3. Combination Therapies:

Artesunate is often used in combination with other antimalarial drugs, such as amodiaquine or mefloquine, to form ACTs. Combining different antimalarial agents helps to reduce the risk of drug resistance and improve treatment efficacy.

4. Rapid Action:

Artesunate is known for its rapid onset of action, making it particularly effective in quickly reducing the parasite load in the bloodstream. This characteristic is crucial in the treatment of severe malaria cases.

5. Formulation:

Artesunate is commonly available in tablet form, making it convenient for oral administration. The tablet formulation allows for accurate dosing, making it easier for healthcare professionals to administer the drug.

6. Treatment Guidelines:

Artesunate is often recommended by health authorities and international organizations, such as the World Health Organization (WHO), as a first-line treatment for uncomplicated and severe malaria in many regions where malaria is endemic.

7. Safety and Side Effects:

While generally well-tolerated, like any medication, artesunate may have side effects. Common side effects may include nausea, vomiting, and dizziness. Serious side effects are rare but can include allergic reactions.

8. Malaria Control Programs:

Artesunate and other artemisinin-based combination therapies play a crucial role in global malaria control programs. These programs aim to reduce the burden of malaria and prevent the development of drug-resistant strains of the parasite.

It's important to note that the use of antimalarial medications, including Artesunate, should be guided by healthcare professionals, and adherence to prescribed treatment regimens is essential for successful outcomes. Additionally, the availability and recommended formulations may vary by region and healthcare practices.

Precautions of Artesunate 

Parenteral artesunate should be used for the treatment of severe falciparum malaria only where there is evidence that the antimalarial efficacy of quinine is declining. The powder for injection is difficult to dissolve and care should be taken to ensure that it is completely dissolved before parenteral administration. It should always be used immediately following reconstitution. If the solution is cloudy or a precipitate is present, the parenteral preparation should be discarded.

Use in Pregnancy

Little experience has been gained with the use of this drug in pregnancy but the parenteral preparation should not be withheld if it is considered life-saving to the mother.

Adverse effects

Drug-induced fever can occur. Neurotoxicity has been observed in animal studies but not in humans.

  • parenterally: treatment of severe falciparum malaria in areas where there is evidence of quinine resistance. Radical cure is then effected with a full course of an effective oral antimalarial.

How it works

Artesunate belongs to class of medications called anti-malarial. It acts by producing free radicals which kills the malarial parasite (plasmodium).

Interactions of Artesunate 

Artesunate is an antimalarial medication that is often used in combination with other antimalarial drugs for the treatment of uncomplicated malaria. It is important to note that the information provided here is general, and specific interactions can vary depending on the formulation and other drugs being taken. Always consult with a healthcare professional or pharmacist for personalized advice based on your specific medical history and medications.

Antimalarial Combinations:

Artesunate is often used in combination with other antimalarial drugs, such as amodiaquine, mefloquine, or lumefantrine. These combinations are designed to improve the efficacy of treatment and reduce the risk of drug resistance.

Anticoagulants:

Artesunate may enhance the anticoagulant effect of drugs like warfarin. Close monitoring of blood clotting parameters is recommended if these drugs are used concomitantly.

Anticonvulsants:

There is a potential for decreased plasma concentrations of anticonvulsant drugs (e.g., phenytoin) when used with antimalarials like artesunate. Monitoring of anticonvulsant levels may be necessary.

Antiretroviral Drugs:

The combination of certain antiretroviral drugs, particularly protease inhibitors, with artesunate may alter the metabolism of these drugs. Close monitoring and dose adjustments may be needed.

CYP2A4 Inducers/Inhibitors:

Artesunate is metabolized by the CYP2A4 enzyme. Drugs that induce or inhibit this enzyme may affect the metabolism and efficacy of artesunate.

Quinidine and Halofantrine:

Concurrent use of artesunate with quinidine or halofantrine may increase the risk of QT prolongation and should be avoided or closely monitored.

Pregnancy and Lactation:

The safety of artesunate during pregnancy and lactation is not well-established. The benefits and risks should be carefully considered, and the medication should be used only if the potential benefits outweigh the potential risks.

Liver Function:
