Option: 4

Correct Option (C)

Your immune system's chemical histamine can overreact to allergens like pollen and pet dander, resulting in symptoms like coughing, sneezing, and watery eyes. Antihistamines treat allergies as well as stomach issues, colds, anxiety, and other conditions.

Antihistamines are a class of drugs that are frequently used to treat allergy symptoms. These medications assist with treating conditions brought about by an excess of receptors, a synthetic made by your body's resistant framework. People who are allergic to pollen or other allergens are the most likely to take antihistamines. They are also used to treat stomach issues, colds, anxiety, and a variety of other conditions.


Option (A) How exactly antidepressants work is unknown. They are thought to function by elevating levels of neurotransmitter chemicals in the brain. There is a connection between mood and emotion and certain neurotransmitters like serotonin and noradrenaline. Some antidepressants may be able to alleviate long-term pain because neurotransmitters also affect nerve pain signals. Although antidepressants can alleviate depression's symptoms, they do not always address the root causes. As a result, they are frequently used in conjunction with therapy to treat more severe forms of mental illness like depression.

Option (B) A complex physiological response to infectious or aseptic stimuli is what causes fever. Prostaglandin E(2) (PGE(2)) concentrations rise in specific brain regions, resulting in body temperature rises. The hypothalamic neurons that regulate thermoregulation change firing rates as a result of these elevations. Fever is seen as a source of discomfort and is frequently suppressed with antipyretic medication, even though it helps the nonspecific immune response to invading microorganisms. Since the late 19th century, aspirin and other antipyretics have been widely used, but their mechanisms for relieving fever have only been characterized in the last few decades. It is presently certain that most antipyretics work by hindering the catalyst cyclooxygenase and decreasing the degrees of PGE(2) inside the nerve centre. Antipyretic medications have recently been suggested to have additional mechanisms of action, such as the ability to lower proinflammatory mediators, boost anti-inflammatory signals at injury sites, or boost antipyretic messages in the brain.

Option (D) When fighting infections, antibiotics are potent medications. You or a loved one may have an infection that can be treated with antibiotics, according to your healthcare team. Antibiotics are not always used to treat infections. Antibiotics may be able to treat infections caused by germs (bacteria), but they can't treat viruses. Antibiotics, like all drugs, can cause side effects, so only use them when necessary. Even if you don't need it, taking an antibiotic can be harmful. Antibiotics require some important understanding as a result.
