Anesthetic, also spelled anaesthetic , any agent that produces a local or general loss of sensation, including pain. Anesthetics achieve this effect by acting on the brain or peripheral nervous system to suppress responses to sensory stimulation. The unresponsive state thus induced is known as anesthesia n anxiolytic (also antipanic or antianxiety agent) is a drug used for the treatment of anxiety, and its related psychological and physical symptoms. Anxiolytics have been shown to be useful in the treatment of anxiety disorders.
Anticonvulsant The anticonvulsants, sometimes also called antiepileptics, belong to a diverse group of pharmaceuticals used in prevention of the occurrence of epileptic seizures. Antimigraine medications are drugs that are given to lower the risk of a severe migraine attack or to reduce the severity of the headache once an attack begins An antiparkinson, or antiparkinsonian, is a type of drug which is intended to treat and relieve the symptoms of Parkinson’s disease (PD) or Parkinsonism.
Most of these agents act by either increasing dopamine activity or reducing acetylcholine activity in the central nervous system (CNS). Antipyretics (literally “against the fire”) are drugs that reduce fever.  They will not normally lower body temperature if one does not have a fever. Antipyretics cause the hypothalamus to override an interleukin-induced increase in temperature. The body will then work to lower the temperature and the result is a reduction in fever. Ant vertigo Drugs Reduce the symptoms of vertigo, tinnitus ; hearing loss associated w/ Meniere’s diseas.
Analgesic An analgesic (colloquially known as painkillers) is any member of the diverse group of drugs used to relieve pain and to achieve analgesia. Edema means swelling caused by fluid in your body’s tissues. It usually occurs in the feet, ankles and legs, but it can involve your entire body. Dementia (taken from Latin, originally meaning “madness”, from de- “without” + ment, the root of mens “mind”) is a serious loss of global cognitive ability in a previously unimpaired person, beyond what might be expected from normal aging.
It may be static, the result of a unique global brain injury, or progressive, resulting in long-term decline due to damage or disease in the body. Antidepressants are drugs used for the treatment of clinical depression and other conditions, including anxiety disorders, obsessive compulsive disorder, eating disorders, chronic pain, neuropathic pain and, in some cases, dysmenorrhea, snoring, migraines, attention-deficit hyperactivity disorder(ADHD), substance abuse and sleep disorders.
Antipsychotic drugs are a class of medicines used to treat psychosis and other mental and emotional conditions Hypnotic (also called soporific) drugs are a class of psychoactives whose primary function is to induce sleep and to be used in the treatment of insomnia, and in surgical anesthesia. When used in anesthesia to produce and maintain unconsciousness, “sleep” is metaphorical as there are no regular sleep stages or cyclical natural states; patients rarely recover from anesthesia feeling refreshed and with renewed energy.
Gout drugs are medicines that prevent or relieve the symptoms of gout, a disease that affects the joints and kidneys anti osteoporosis drugs The goal of osteoporosis treatment is to prevent broken bones and fractures. This is done by stopping bone loss and by increasing bone density and strength antirheumatic drugs These drugs not only treat arthritis symptoms, but they also can slow down progressive joint destruction. Some of these medications have been used to treat other conditions, such as cancer or inflammatory bowel disease, or to reduce the risk of rejection of a transplanted organ.
Nonsteroidal anti-inflammatory drugs, usually abbreviated to NSAIDs /?? ns? d/ ehn-said—but also referred to as nonsteroidal anti-inflammatory agents/analgesics (NSAIAs) or nonsteroidal anti-inflammatory medicines (NSAIMs)—are a class of drugs that provideanalgesic and antipyretic (fever-reducing) effects, and, in higher doses, anti-inflammatory effects. Muscle relaxants are used to relieve muscle spasms which may result from some conditions which affect the nervous system, such as multiple sclerosis, motor neurone disease, cerebral palsy, or following long-term injuries to the head or back.
They work by causing the muscles to relax, which may also reduce pain and discomfort. Spasmolytic drugs are prescription medications which are most commonly used to reduce or prevent muscle spasms, especially spasms in the digestive tract. An antibacterial is an agent that inhibits bacterial growth or distinguishes bacteria. Bacteria can not be fully killed or removed, therefore antibacterial drugs are prescribed to the user to repair the most it can.  The term is often used synonymously with the term antibiotic(s).
Today, however, with increased knowledge of the causative agents of various infectious diseases, antibiotic(s) has come to denote a broader range of antimicrobial compounds, including anti-fungal and other compounds.  Antibacterials must be distinguished from disinfectants (sanitizing agents), which are less-selective substances used to destroy microorganisms. An antifungal medication is a pharmaceutical fungicide used to treat mycoses such as athlete’s foot, ringworm, candidiasis (thrush), serious systemic infections such as cryptococcalmeningitis, and others.
Anthelmintics or antihelminthics are drugs that expel parasitic worms (helminths) from the body, by either stunning or killing them. They may also be called vermifuges (stunning) or vermicides (killing). Antiprotozoal drugs are medicines that treat infections caused by protozoa. Antiviral drugs are a class of medication used specifically for treating viral infections.  Like antibiotics for bacteria, specific antivirals are used for specific viruses. Unlike most antibiotics, antiviral drugs do not destroy their target pathogen; instead they inhibit their development. Diagnostic agent
Definition: A substance administered to aid diagnosis of a disease. Immunoglobulin: A protein produced by plasma cells and lymphocytes and characteristic of these types of cells. Immunoglobulins play an essential role in the body’s immune system. They attach to foreign substances, such as bacteria, and assist in destroying them A vaccine is a biological preparation that improves immunity to a particular disease. A vaccine typically contains an agent that resembles a disease-causing microorganism and is often made from weakened or killed forms of the microbe, its toxins or one of its surface proteins
