Antimalarial
"Antimalarial" refers to something that is used to prevent or treat malaria, a disease caused by parasites transmitted through the bite of infected mosquitoes. It can refer to medications, treatments, or measures taken to counteract or alleviate the effects of malaria.
Antimalarials
Antimalarials are medications used to prevent and treat malaria, a disease caused by parasites transmitted through the bite of infected mosquitoes. These drugs work by killing the parasites or inhibiting their growth inside the human body, helping to either prevent the onset of malaria symptoms or to treat an existing infection. Common antimalarial drugs include chloroquine, hydroxychloroquine, mefloquine, doxycycline, and atovaquone-proguanil.
Antimalarics
Antimalarics are medications or drugs used to prevent and treat malaria, a disease caused by parasites transmitted through the bites of infected mosquitoes. These drugs help in controlling the symptoms, reducing the severity, and preventing complications of malaria. Some common antimalarial drugs include chloroquine, quinine, artemisinin-based combinations, and mefloquine.
Antimanic
"Antimanic" refers to a medication or treatment that is used to control or reduce the symptoms of mania, a condition characterized by abnormally elevated or irritable mood, increased energy, impulsiveness, and other manic episodes typically associated with bipolar disorder.

Antimaterial
"Antimaterial" refers to something that is opposed to or contradictory of materialism, the belief that physical matter is the only reality and the ultimate basis of all knowledge and existence.

Antimatter
Antimatter is a type of matter composed of particles that are opposite in charge to their corresponding particles in normal matter. For example, an antiproton has the same mass as a proton but carries a negative charge, while an antielectron (or positron) has the same mass as an electron but carries a positive charge. When antimatter comes into contact with normal matter, they annihilate each other, releasing energy in the form of gamma rays or other particles. Antimatter is rare in the observable universe, and its study is important in fields such as particle physics and potential applications in energy production or space propulsion.
Antimere
"Antimere" refers to a term used in anatomy, particularly in the study of bilateral symmetry. It describes a structure or part of an organism that is situated directly opposite another structure on the body, with both being mirror images of each other. For example, the left and right hands of a human are antimeres because they are symmetrical but inverted versions of one another.
Antimerism
Antimerism refers to the phenomenon in chemistry where a molecule has two structurally different but mirror-image forms, often resulting from the arrangement of its asymmetric atoms or groups. These forms are non-superimposable on each other, similar to how left and right hands are not identical when placed one over the other. In biology, it can also refer to the presence of two dissimilar halves or organs in an organism.
Antimetabole
