Medicine for Malaria

QUESTION

is rotam and maladar malaria medicine?

ANSWER

I have never heard of Rotam, but Maladar is the brand name of a combination sulfadoxine-pyrimethamine, and is used to treat malaria. However, it should be noted that it is not recommended by the World Health Organization as a first-line treatment option, due to concerns about drug resistance, and also lack of efficacy against certain types of malaria.

Instead, first-line recommended treatment is of an artemisinin-based combination therapy, or ACTs, which combine an artemisinin derivative (such as artesunate, artemether or dihyrdoartemisinin) with another anti-malarial drug, such as lumefantrine, piperaquine or mefloquine. Common brand names include Coartem, Lonart and Duo-Cotecxin.

QUESTION

What medicine is good for curing malaria?

ANSWER

There are lots of different types of medication which are effective against malaria. However, for uncomplicated, unsevere cases, the World Health Organization (WHO) recommends using a type of medication called artemisinin-based combination therapy, or ACT. Again, there are many types of ACTs, so the name may vary depending on what is most common in your area, but some widespread brands include Coartem, Lonart, Duo-Cotecxin, etc. In some countries, they are known by an abbreviation of the drug name – for example, in Tanzania, the most common ACT is a combination of artemether and lumefantrine, and the different brands are collectively known as Alu.

For severe or complicated malaria (there is no hard and fast definition, but the clinical diagnosis may include cerebral involvement, seizure, coma, inability to take oral medication, severe anaemia, etc), the WHO recommends intravenous  (IV) artesunate, with quinine as a second choice.

There are also additional forms of treatment which may be used in certain settings, depending on the geographical region and the type of malaria, or if one of the above treatments is not successful. Likewise, pregnant women should not take ACTs, so they need to seek alternative forms of treatment, such as chloroquine (if the local malaria is known to be sensitive), mefloquine or sulfadoxine-pyremethamine.

Malaria Diagnosis

QUESTION

My body is getting hotter after taking artesunate and mtivitamen tablet, the pain subsides, but later in the evening my body starts getting hotter, I have taken almost four artesunate, yet the body pain and headache refuse to go, pls sir is it malaria or what.

ANSWER

Unfortunately the symptoms of malaria are quite general, and just having a fever could be a sign of malaria but also of many other diseases. You should go to a doctor or clinic to have a blood test—there, they will take some of your blood and look at it under the microscope to determine whether you have malaria parasites in your blood. If you do, they will give you appropriate treatment—it is actually not recommended to take artesunate by itself, and rather it should be taken together with a secondary anti-malarial drug, in a combination known as an artemisinin-based combination therapy (ACT).

Common forms of ACTs available in Africa include artemether-lumefantrine (sold as Alu, Lonart or Coartem) and dihydroartemisinin-piperaquine (sold as Artekin or Duo-Cotecxin). Artesunate comes in combination with amodiaquine, and is often abbreviated as ASAQ.

If you do not get properly diagnosed in a medical facility, you risk treating yourself with unnecessary drugs if in fact you actually have another infection, or you might find you are giving yourself the wrong type of treatment for your malaria infection.

Doxycycline After Malaria Diagnosis

by

QUESTION

My daughter is 24 and in rural Uganda for 4 months. She has been diagnosed with malaria (plasmodium falciparum) and is taking treatment now. Treatment is 3 tablets of Neosidar tablets contain of sulfadoxine BP and of pyrimethamine followed tonight and for the next 3 days by 4 tablets of Lumarten in the morning and at bedtime with milk. Lumarten is a mix of artemether and lumefantrine. Her doctor in Entebbe recommended she should stop taking doxycycline: “the doxy is like a lock on the door, and now someone has broken the lock, so it’s better to treat the malaria as it comes (while still using nets, bug spray, long sleeves, etc. to avoid bites) rather than keep taking the doxy every day.”

Should she stop taking doxycycline and should she be taking the Lumarten with milk? Thank you very much.

ANSWER

I am not personally familiar with Lumarten, but these antimalarials are often taken with food. Of more concern is that she has been given a sulfadoxine-pyramethamine treatment—these are no longer recommended as first line treatment against malaria, and so she should just take the artemisinin-based combination therapy (artemether-lumefantrine is such a combination therapy).

In terms of the doxycycline, I do not understand the doctor’s advice. There is no harm in continuing to take doxycycline after having malaria, and in fact it might prevent re-infection! Of course this depends on how long she is still in Uganda for—the doxy must be taken for four weeks after leaving the malarial area, so if she is returning home soon, she should weigh up the continued preventive benefit against the inconvenience of a long continuation of taking the medication. In general, I don’t like the doctor’s attitude that your daughter should just accept continuing infections with malaria, and “treat them as they come.” It’s much better to use all available methods for prevention. One thing to consider is that dairy products inhibit the uptake of doxycycline, so if your daughter was also taking her doxy with milk (some doctors mistakenly advise this, to prevent stomach upsets when taking the medication), that might have been one reason why she still got infected.

Malaria Treatment and Prevention Methods

by

QUESTION

I work in Central Africa republic.I was recently diagnosed with malaria (p.falciparum) after a blood test—my 4th attack in 15 months and given Co-Arinate. Two days after completing my dose I went for a 2nd blood test and the trophozoite count was 720/mm3.

The doctor prescribed co-artem and said if I don’t get better he shall transfuse quinine. Whats your comment on the treatment? Do these malaria medications/attacks have a long term effect on ones liver? What prophylaxis should I consider to prevent future attacks.

ANSWER

I will forward your question on to one of the medical professional who advises our website. However, normal procedure after treatment failure or incomplete treatment with one type of anti-malarial medication would be to try another type of medication first; Co-Arinate might not have been an ideal first choice given that many types of malaria around the world are showing signs of resistance to pyrimethamine, the combination drug in Co-Arinate.

Co-Artem would be a better first choice drug, given that there is no convincing evidence for resistance to its combination compound, lumefantrine. Quinine could be a potential next step though I would imagine Co-Artem will be successful—make sure the drugs have not expired and are in their original packaging, as counterfeit medication is a problem in many parts of the world.

Regarding prevention, a key method is to sleep under a long-lasting insecticide treated bednet; make sure it is re-dipped in insecticide every year or so to maintain its efficacy. The mosquitoes which transmit malaria tend to feed at night, and so protecting yourself and your home during the evening, night and early morning is crucial. Maintaining good screens on all windows and doors can be a very effective way of preventing mosquitoes from entering, and in many parts of the world, people spray inside with insecticides to reduce the number of mosquitoes yet further. Wearing long-sleeved clothing at night and in the evenings can also prevent bites.

More broadly speaking, you can try to make sure that stagnant water sources, such as empty containers or barrels, are removed, as mosquitoes require still water to breed. Reducing the presence of stagnant water will therefore reduce mosquito numbers; treating standing water with larvacides or adding fish that eat mosquito larvae can also help.

New Treatment for Malaria

by

QUESTION

New treatment for malaria?

ANSWER

The most recently developed type of treatment for malaria actually has very ancient origins. The herb wormwood (Artemisia annua) has been used in ancient Chinese medicine for hundreds, even thousands, of years to cure certain fevers.

In the 1970s, a Chinese research program intensively sought new medications against malaria, as part of their Vietnam war effort. They re-discovered wormwood, and from it isolated the compound artemisinin, which is highly effective against malaria parasites in the blood, and kills them very quickly. Due to its quick action against malaria, there was concern that use of artemisinin alone would lead to resistance developing rapidly in the malaria parasite, as was seen with chloroquine in many parts of the world. As such, the World Health Organisation recommended that artemisinin should only be used in combination with another anti-malarial drug with a longer lasting action, to prevent resistance.

A number of such compounds, containing artemisinin derivatives and a second anti-malarial, have now been developed. These are collectively called “artemisinin-based combination therapies,” or ACTs. Some of the main artemisinin compounds used in these drugs are artemether, artesunate and dihydroartemisinin, and the brand names of the drugs as they are marketed (in combination with other compounds, such as lumefantrine, piperaquine and pyronaridine) include Coartem, Pyramax and Duo-Cotecxin.

How is Malaria Treated

by

QUESTION

How is malaria treated today?

ANSWER

Several different medications exist which are used for the treatment of malaria. The exact drug and method of treatment depends somewhat on the type of malaria the patient is infected with.

In most cases of non-complicated (i.e. when the patient is stable and conscious) malaria, the World Health Organisation recommends an orally-administered (in the form of solid pills) artemisinin-based combination therapy (ACT), such as Coartem (a combination of artemether and lumefantrine). Other types of medication include atovaquone-proguanil (Malarone) and sulfadoxine-pyrimethamine (Fansidar). In some locations, where chloroquine-resistance is not a problem, chloroquine can also be used as a treatment. For complicated malaria, where the patient is in a more severe state, intravenously administered quinine is usually the first-line treatment.

If diagnosed early and the patient is given appropriate medication, virtually all cases of uncomplicated malaria can be effectively treated.

Treatment of Malaria in India

by

QUESTION

In India how to treat a child and adult suffering from malaria?

ANSWER

Chloroquine-resistant malaria has been observed in India and so the first line drug of choice should be an artemisinin-derivative in combination with another drug (this group of medications are more generally known as “artemisinin-based combination therapies” or ACTs). A common example of this is artemether in combination with lumefantrine, which is marketed as Coartem. Coartem is also used to treat malaria in children over 11 pounds (5 kg) in weight.

Child Has Recurring Malaria

by

QUESTION

My two year old daughter was affected by malaria 9 months back we took proper course and also the follow up course of 6 weeks. After 2 months post 6 weeks she was infected again by malaria and now again she is getting fever and fear this could be malaria again.

ANSWER

If you suspect she might have malaria again it is important you go and get her tested immediately, as then the doctor can prescribe appropriate treatment. This is particularly important for young children, as they are most susceptible to severe malaria. You should also try to find out what type of malaria she had/has. Repeated attacks of malaria can occur three ways. The first is re-infection – the first infection was cured by the medication, but then your daughter was exposed to malaria again, through the bite of an infected mosquito. Preventative measures, such as making sure she sleeps under a long-lasting insecticide treated bednet, can help reduce the risk of re-infection. Secondly, it could be what is called “recrudescence” – this is when the treatment brings the number of parasites in the blood below detectable levels, and low enough so that symptoms subside.

However, once the treatment course stops, the parasite is able to replicate in the blood again, and symptoms return. This is rare if the full, proper course of medication is taken – in most circumstances, Coartem (artemether plus lumefantrine) should be the first line of treatment and it is very effective against preventing recrudescence. Finally, there is relapse. This only occurs with two species of malaria: Plasmodium vivax and Plasmodium ovale. In this case, the parasite is cleared from the blood by the treatment, but some parasites escape by laying dormant in the liver. These can then reactivate weeks, months or even years after the initial infection. Normal malaria medication can be given to treat relapses of infection, but an additional drug, called primaquine, should also be given, to kill the remaining dormant liver stages. Your doctor should be able to tell you whether he would recommend this drug for your child – they should also be tested for G6DP deficiency prior to taking the drug.
