Abstract :

The power laws are ubiquitous but we have to find them . Recently, power laws are extensively studied almost in every field -Science, Engineering, Economics Finance and Management. For the past three years, we have been working on applications of Power Laws to Pharmaceutical phenomena. We found power laws operating in pharmaceutical literature (Pharmacists?oaths of USA and India), in most of the editorials of reputed Indian English news papers (Times of India, Hindu, Deccan Chronicle, Economic Times etc.,); Pharmaceutics (frequency and ranks of oil globules in emulsions, Powder Technology (Sieve analysis), Epidemiology (prevalence of H1N1 in USA and global (2010); Pharmaco-Epidemiology-ADEs with regard to certain selected drugs. Existing estimations of drug dosing are based on body weight-kg/mg. As the drug clearance rate is dependent upon metabolic rate, there is a pressing need to bring in metabolic rate into equation while titrating doses of drugs. We have compared and contrasted three methods of dosing of drugs: Dosing by body weight (kg/mg)?Linear dosage Scale, Dosing by ¾ Power Law (Kleiber?s Law), and Dosing by 2/3 Power Law (Rubner?s Law). From the data available in public domain, ADEs were extracted for Tami flu, Avandia, Celebrex, Bextra, Paxil, and Relenza. Using least-square method, hypothetical ADEs were estimated in each case, when Kleiber?s Law / Rubner?s Law were inserted into the equations of dosings.
