Absorption

Parmacokinetics
Pharmacokinetics includes absorption distribution metabolism and excretion of drugs (ADME).

Absorption

Absorption is movement of the drug from its site of administration into the circulation. Not only dose of the administered dose that get absorbed but also the rate of absorption is important.
Absorption
Absorption

Biological Membrane

Biological membrane is bilayer of phospholipid and cholesterol. Cell membrane thickness is about 100Ã…. Extrinsic and intrinsic proteins molecules are adsorbed on the lipid bilaryer.
  
Transport is movement of drug molecules from site of administration to blood circulation so that it may reach to its site of action. 

Oral drug involves absorption step but parenteral route escape absorption step because parenteral drug directly administrated into the bloodstream.  

Those drugs, which are administered by buccal cavity called oral route. Many dosages forms are available in oral route including tablet, capsule, syrup, suspension, emulsion etc. When drug is reach to blood than its produce pharmacological action.  

Factor affecting absorption

Various factor are involves in affecting absorption.

Vascularity of absorbing surface

Blood circulation removes the drug from the site of absorption and maintains the concentration gradient across the absorbing surface.

Physical state of drugs

Physical states of drugs are also playing vital role in absorption. Liquid drugs are better absorbed than solid medications. Crystalline form drugs are more readily absorbed colloids form. Aqueous solutions are more quick absorbed than oily solutions. 
  

pH of Drugs

Basic drugs are not absorbed until they reach the small intestine. 

Example – Ephedrine

Acidic drugs are rapidly absorbed from the stomach. 

Example – Aspirin, barbiturates.    

Concentration

Passive diffusion depends on concentration. Drug given as concentrated solution is absorbed faster than from dilute solution.

Route of administration

This affect drug absorption because each route has its own specialty.
 

Aqueous solubility 

Drugs given in solid dosage form must dissolve in the aqueous biphasic before they are absorbed.   

Drug absorption mechanism or Drug Transporting System 

So many of mechanisms are involves in transporting drug from site to bloodstream. These mechanisms are known as drug transport system.  
classification-of-drug-transporting-system-diagram
classification of drug transporting system

Passive diffusion

Diffusion process is also known as simple diffusion. Cell membrane is not actively involved in this process.

In diffusion process, high concentration to low concentration through the semi-permeable membrane. 

Diffusion is an automatic process. In this process energy is not required.

The cell membrane is a lipid bilayer and hence the lipid soluble drugs diffuse quickly than the water soluble drugs. Diffusion is bidirectional process, where the rate of transfer of drug molecules is proportional to the concentration gradient across cell membrane. 

Small non-polar molecules (such as gases) and small uncharged polar molecules such as water urea etc follow the diffusion process for transporting inside the cell and outside the cell. 

Pinocytosis

This process is also known as cell engulfing phenomena. Small molecules are engulf by cell process known as pinocytosis.
 
Large molecules are engulf by cell process known as phagocytosis. 

Carrier Transport

All cell membrane express a host of trans-membrane proteins which serve as transporter or carrier for physiologically important ions, metabolites, nutrients and transmitters etc across the cell membrane.

Eg- ion channel, transporter, antiport, symport etc.
  

Facilitated diffusion

The transpoter is belonging to the super family of solute carrier (SLC) tansporters. SLC transporter operates passively without needing energy and translocates the substrate in the direction of its concentration(i.e. higher to low concentration).

Example – the entry of glucose into fat cells and muscles by the GLUT4 transporter.

Active transport

Transports of substance against its electrochemical gradient(i.e. low to high concentration). Hydrolysis of ATP is required to power for active transport (energy is required).

Active transport is two types –

Primary active transport

Single solute transport, low to high concentration though the transporter. 
 

Secondary active transport

Two solute transport, low to high concentration through the same transporter. 

Secondary active transport is two types

Symport – When two solutes are transport through the same transporter in the same direction. 

Antiport – When two solutes are transport through the same transporter in the opposite direction.

Blood Groups and Rh Factor

Blood-Groups-and-Rh-Factor
Blood Groups and Rh Factor
The antigens are genetic substance which composed of glycoprotein and glycolipid. These antigens are present on the surface of red blood cells. These Antigens are also known as agglutinogens. The antibodies are present in blood plasma, called agglutinin

Based on the presence or absence of various antigens and antibodies, blood is divided into different blood groups.

Blood divided into two major blood groups:
  1. ABO group
  2. Rh blood group

ABO group

Based on A and B antigen and antibody, ABO blood group are four blood types.

Type A: The Red blood cells display only A antigen and blood plasma contain anti-B antibody.  These people carries blood group A.

Type B: The red blood cells display only B antigen and blood plasma contain anti-A antibody.  These people carries blood group B.

Type AB: The Red blood cells display both A and B antigen but absence of antibody in blood plasma.  These people carries blood group AB.

Type O: In this type, red blood cells do not contain any antigen (either A nor B antigen) but blood plasma display both anti-A and anti-B antibodies. These people carries blood group O.

Rh blood group

Rh blood group was first found in rhesus monkey. That blood group contains a different type of antigen that is Rh antigen, called Rh factor
Red blood cells have Rh antigen which is Rh positive (Rh+) and people whose absent of Rh antigen are designated Rh negative (Rh-).  

Function of blood


Function of blood are given below

Transportation

  • Blood transport various essential elements to cells, these elements are necessary for many metabolic reaction.
  • Blood carry oxygen to cells and take back carbon dioxide to lungs.
  • Blood carrier for many hormone and enzymes.
  • Blood transport nutrition and essential elements to cells for growth and development. 

Regulation

  • Blood help maintain homeostasis of all body fluids.
  • Blood maintain pH through using buffers. Blood also regulate body temperature. 

Protection

  • Blood make a gel like structure, called clot, which protect against blood excessive loss from the cardiovascular system after the injury.
  • Various type of blood cells protect against disease in a variety of ways.
  • White blood cells protect against disease by phagocytosis.

Physiology of Muscle Contraction

Physiology-of-muscle-contraction
Physiology of muscle contraction
Release of Acetylcholine
Action potential comes to nerve terminal, that potential open the voltage gated calcium channels at nerve terminal. The movement of calcium ion inside the cell. Vesicles filled with acetylcholine present at nerve terminal. Calcium evoked vesicle of Ach. Ach vesicles are ruptured and release Ach.

Activation of Ach Receptors


Two molecules of Ach Ach binding  to Ach receptor on the motor end plate. Voltage gated sodium channels are open and influx of sodium ion in muscle fibers. 

Production of Muscle Action Potential 


Numbers of sodium ion inside muscle fiber are increase and generate action potential that potential cause muscle contraction.

Sodium ions enter inside the cells and potassium ions comes out from cell, changes of ion produce electrical charge. Both interior and exterior of muscle cell become positively charge.

Membrane get depolarized, this depolarization cause contraction. 

When the muscle contraction is over, then acetylcholine destroyed by acetylcholinersterase. After this potassium ions move into the cell and sodium ions move out of the cell, this potential stage called repolarization.
