Pharmaceuticals are generally classified by chemical group, by the way they work in the body \(pharmacological effect\), and by therapeutic use. Alkaloids were the first pure pharmaceuticals derived from natural substances \(plants\); they include quinine, nicotine, cocaine, atropine, and morphine. Drugs of animal origin include glandular extracts containing hormones such as insulin using in treating diabetes. Antibiotics, vaccines, human blood-plasma fractions, and steroid hormones are other important pharmaceuticals manufactured from natural substances. Vitamins, which were formerly obtained from natural sources, are now often made in the laboratory. In the preparation of dosages, many pharmaceuticals are ground to varying degrees of fineness. Many medicinal substances are added to water, alcohol, or another solvent so that they can be used in solution form. These may include elixirs and tinctures. Ointments are different semisolid preparations which include creams, pastes, and jellies. Solid pharmaceuticals include pills, tablets, lozenges, and suppositories. In this form the compounds are more stable, with less risk of chemical reaction, and the dosage is easier to determine. Storage and packaging are made simpler, and solid forms are more efficient to produce.
