Malaria is caused by infection with parasites in the genus Plasmodium. [47] In humans, malaria is caused by six Plasmodium species: P. falciparum, P. malariae, P. ovale curtisi, P. ovale wallikeri, P. vivax and P. knowlesi. [48] Among those infected, P. falciparum is the most common species identified (~75%) followed by P. vivax (~20%). [15]
Artemether is a medication used for the treatment of malaria. [1] [2] The injectable form is specifically used for severe malaria rather than quinine. [2] In adults, it may not be as effective as artesunate. [2] It is given by injection in a muscle. [2] It is also available by mouth in combination with lumefantrine, known as artemether ...
Because of the drug's very long half-life, the Centers for Disease Control originally recommended a mefloquine dosage of 250 mg every two weeks; however, this caused an unacceptably high malaria rate in the Peace Corps volunteers who participated in the approval study, so the drug regimen was switched to once a week. [14]
Coartem can cause anaphylactic reactions.The drug frequently causes headache, dizziness and anorexia, although mild forms in most cases.Other fairly common side effects (more than 3% of patients) include sleep disorder, tinnitus, tremor, palpitation, as well as unspecific reactions like vertigo, gastrointestinal disorders, itch and nasopharyngitis.
Found worldwide, it causes a so-called "benign malaria", not nearly as dangerous as that produced by P. falciparum or P. vivax. The signs include fevers that recur at approximately three-day intervals – a quartan fever or quartan malaria – longer than the two-day (tertian) intervals of the other malarial parasite.
It is still a useful drug and can be used in patients that are known to be free of heart disease and that have severe and resistant forms of acute malaria. [citation needed] A popular drug based on halofantrine is Halfan. The level of governmental control and the prescription-only basis on which it can be used contributes to the cost, thus ...
When it comes to non-prescription aphrodisiacs and male enhancement pills, most are big on promises but small on actual results. The evidence that Spanish fly works is, likewise, scant.
Malaria is caused by a protozoan called Plasmodium falciparum. P. falciparum parasites are transmitted mainly by the Anopheles gambiae complex in rural Africa. [58] In just this area, P. falciparum infections comprise an estimated 200 million clinical cases and 1 million annual deaths. 75% of individuals affected in this region are children. [61]
