Antimalarials are a class of drugs that are specifically designed to prevent or treat malaria, a life-threatening disease caused by the Plasmodium parasite. These drugs work by either killing the parasites or inhibiting their growth and development inside the human body.
There are several types of antimalarial drugs available, including quinine and its derivatives, chloroquine, mefloquine, atovaquone/proguanil, doxycycline, and artemisinin-based combination therapies (ACTs). These drugs may be used individually or in combination depending on the type of malaria, the severity of the infection, and the geographical location.
Antimalarials are typically administered orally in the form of tablets or capsules, while in severe cases or when oral administration is not possible, they may be administrated intravenously. The choice of antimalarial drug depends on factors such as the species of Plasmodium causing the infection, drug resistance in the local area, the patient's age, pregnancy status, and any existing medical conditions.
It is important to note that while antimalarials can be highly effective in preventing and treating malaria, the parasites responsible for the disease have developed resistance to certain drugs in some regions. Therefore, it is crucial to use the appropriate antimalarial drugs based on the guidance of healthcare professionals and to follow the prescribed dosage regimen to ensure maximum efficacy and minimize the risk of drug resistance.
The word "antimalarials" has a relatively straightforward etymology.
The term is a compound word that combines two parts: "anti-" and "malarial".
1. "Anti-" is a prefix derived from the Greek word "antí", meaning "against" or "opposite". It is commonly used as a prefix to denote opposition, negation, or cure against a particular thing or condition.
2. "Malarial" is derived from the noun "malaria". "Malaria" originated from the Medieval Latin word "malaria", which combines "mala" meaning "bad" and "aria" meaning "air".
The term "malaria" was used in reference to a disease transmitted by mosquitoes in marshy regions. In earlier times, it was believed that the disease was caused by breathing in polluted air in these regions.
