Pharmaceuticals are drugs or medications that are used for medical treatment or prevention of diseases. They are typically developed and manufactured by pharmaceutical companies through a process of drug discovery, research, clinical trials, and regulatory approval.
Pharmaceuticals can be classified into various categories based on their therapeutic use, chemical structure, and mode of action. Some common categories of pharmaceuticals include antibiotics, antivirals, analgesics, anti-inflammatory drugs, antidepressants, antipsychotics, and cardiovascular drugs.
Pharmaceuticals are regulated by government agencies such as the U.S. Food and Drug Administration (FDA) to ensure their safety, efficacy, and quality. They are available in various forms such as tablets, capsules, injections, creams, ointments, and inhalers, and are prescribed by licensed healthcare professionals such as doctors, nurses, and pharmacists.
