Lipinski's rule of five, also known as Pfizer's rule of five or simply the rule of five (RO5), is a rule of thumb to evaluate druglikeness or determine if a chemical compound with a certain pharmacological or biological activity has chemical properties and physical properties that would likely make it an orally active drug in humans.
Aspirin is non-selective and irreversibly inhibits both forms [4] (but is weakly more selective for COX-1 [5]). It does so by acetylating the hydroxyl of a serine residue at the 530 amino acid position. [6] Normally COX produces prostaglandins, most of which are pro-inflammatory, and thromboxanes, which promote clotting.
Pharmacodynamics (PD) is the study of the biochemical and physiologic effects of drugs (especially pharmaceutical drugs). The effects can include those manifested within animals (including humans), microorganisms , or combinations of organisms (for example, infection ).
Steady state is reached after about 5 × 12 = 60 hours. Pharmacokinetics (from Ancient Greek pharmakon "drug" and kinetikos "moving, putting in motion"; see chemical kinetics ), sometimes abbreviated as PK , is a branch of pharmacology dedicated to describing how the body affects a specific substance after administration.

A meta-analysis through 2019 said that there was an association between taking aspirin and lower risk of cancer of the colorectum, esophagus, and stomach. [138] In 2021, the U.S. Preventive services Task Force raised questions about the use of aspirin in cancer prevention.
Smoking was the leading risk factor, contributing to nearly 1 in 5 cancer cases and nearly one-third of all cancer deaths studied, followed by 7% of cases stemming from excess body weight ...
The therapeutic ratio in radiotherapy for cancer treatment is determined by the maximum radiation dose for killing cancer cells and the minimum radiation dose causing acute or late morbidity in cells of normal tissues. [13] Both of these parameters have sigmoidal dose–response curves. Thus, a favorable outcome in dose–response for tumor ...
