A homonculus inside a sperm cell, as drawn by Nicolaas Hartsoeker in 1695 Jan Swammerdam, Miraculum naturae sive uteri muliebris fabrica, 1729. In the history of biology, preformationism (or preformism) is a formerly popular theory that organisms develop from miniature versions of themselves.
[1] Formulation studies then consider such factors as particle size, polymorphism, pH, and solubility, as all of these can influence bioavailability and hence the activity of a drug. The drug must be combined with inactive ingredients by a method that ensures that the quantity of drug present is consistent in each dosage unit e.g. each tablet ...
The phrase "drug design" is similar to ligand design (i.e., design of a molecule that will bind tightly to its target). [6] Although design techniques for prediction of binding affinity are reasonably successful, there are many other properties, such as bioavailability, metabolic half-life, and side effects, that first must be optimized before a ligand can become a safe and effictive drug.
Medicinal or pharmaceutical chemistry is a scientific discipline at the intersection of chemistry and pharmacy involved with designing and developing pharmaceutical drugs. Medicinal chemistry involves the identification, synthesis and development of new chemical entities suitable for therapeutic use.
The preformation theory is a developmental biological theory, which was represented in antiquity by the Greek philosopher Anaxagoras. It reappeared in modern times in the 17th century and then prevailed until the 19th century.
Pharmaceutics is the discipline of pharmacy that deals with the process of turning a new chemical entity (NCE) or an existing drug into a medication to be used safely and effectively by patients. [1] The patients could be either humans or animals. Pharmaceutics helps relate the formulation of drugs to their delivery and disposition in the body. [2]
[3] [4] As of 2010, the editor in chief was Joseph T. DiPiro, [5] Executive Dean at the South Carolina College of Pharmacy. The Journal's founding editor was Rufus A. Lyman (1875–1957), who served from 1937 to 1955. [2]: 254, 470 Lyman was a physician who held the post of Dean of Pharmacy at the Universities of Nebraska and Arizona.
Physical pharmacy is the branch of pharmacy that concentrates on the applications of physics and chemistry to the study of pharmacy. In other words, it is the study of the effects that dosage forms have on their environment by addressing issues at the molecular level. [ 1 ]
