INTRODUCTION TO PHARMACOKINETICS AND BARRIER MEMBRANES


                    
                                                    


     Perhaps, If Tom would have known what's in there and what does it do to him he would not have been this much afraid of the situation.😕
     We all would have faced the same fearful situation 😫 when we were young👶, even we did not know at that time what PHARMACOKINETICS really is and how we are overcoming sickness😊!!!


     PHARMACOKINETICS is defined as the process of how drug concentrations changes with time in one or more different regions of the body in relation to dosing
      For a drug to be utilized in the body it has to overcome various barriers before reaching the target of action.. Mechanisms by which a drug cross these barriers along with their physicochemical properties also play a major role in their movement.

The fluid compartments of the body are divided into Intracellular and extracellular fluids. The extracellular fluid  is further composed of 80% Interstitial fluid and 20% plasma. These compartments are seperated by barrier membranes namely the capillary membrane and the cell membrane. Interstitial fluid is present between these two membranes.

A for Absorption !

Image
Absorption is the movement of drug from its site of administration into the circulation. Not only the fraction of the administered dose that gets absorbed, but also the rate of absorption is important.  Routes of drug administration and absorption of drugs (sr: Rang and Dale's Pharmacology) Except when given intravenous, the drug has to cross biological membranes. Other factors influencing absorption are: Aqueous solubility : Drugs given in the solid form must dissolve in aqueous biophase before they are absorbed. A drug given as watery solution is absorbed faster.  Concentration : Passive diffusion depends on concentration gradient : concentrated drug solution is absorbed faster. Area of absorbing surface : Larger it is, faster the absorption. Vascularity of the absorbing surface : Blood circulation removes drug from site of absorption and maintains concentration gradient. Route of administration : Main routes include oral, sublingual, rectal, topical application, inhalat...

TESTING FOR TOXICITY,MUTAGENICITY & GENOTOXICITY

Image
Testing for Toxicity Both short-term or acute and long-term or chronic toxicity testing are carried out to determine the toxic effects of the drug and mortality in animal models.All these tests are carried out under a standard procedure of "GOOD LABORATORY PRACTICE" to safeguard the quality, integrity, and safety of the preclinical trials.  Drug Development: Drugs must be approved by the FDA before they can be marketed in the US.  Long, costly, and inherently risky: only 1 of 10-15,000 reach FDA approval.  Toxicology testing is required to demonstrate that drugs are safe before they can be given to humans. Testing of Mutagenicity:- Mutagenicity :- Mutagenicity refers to the induction of permanent transmissible changes in the amount or structure of the genetic material of cells or organisms. These changes may involve a single gene or gene segment , a block of genes or chromosomes. Testings: - Carcinogenicity:- Ames test   is used as one of the initial screen...

EVOLUTION OF DRUGS

  Definition  Berries of coffee plant     A drug is defined as any chemical agent that affects the living protoplasm. Drug invention vs Drug discovery A drug discovery is not intentional. A drug invention   is defined as the intentional process Poisonous mushroom by which the drug is sculpted by experimentation &   optimization of individual properties .  Early experiences in chemistry Goats went insane after eating the berries of coffee plant  Professional poisoners used mushrooms and Belladona  Atropa belladona source: www.fs.fd.usa Curare was used by South American tribes for hunting Poppy  was used to relieve pain Chinese herb Ma Huang was used as a circulatory stimulant Rise of Organic chemistry PAUL EHLRICH worked on dyes  He invented arsphenamine named as  Salvarsan - Salvation of humankind  PAUL EHLRICH Father of chemotherapy curare   poppy                 ...
