(4)2.pore transport/mechanism of drug transport

2.pore transport - It is also called as convective transport, bulk flow or filtration. -the process is important in the absorption of low molecular weight (less than 100). -low molecular size (small than the diameter of the pare) generally water-soluble drugs through marrow, aqueous filled channels or pores, in the membrane structure .ex :Urea, H₂o & Sugars.... * Chain-like.. or linear compounds of molecular weight upto 400 daltons can be absorbed by filtration. * The driving force is constituted by the hydrostatic pressure/ the asmotic differences across the membrane due to which bulk flow of water along with solid molecules occurs through, aqueous such channels →water flux that promotes such a transport is called as solvent drug. -drug permeation through water filled channels or of particular importance in renal excretion,removal of drug from the cerebrospinal fluid and entry of drugs into the liver. Note:next topic will be continued I next blog

(4).3.carrier mediated transport/mechanism of drug absorption/biopharmaceutics

3.carrier mediated transport - the presence of specialised transport mechanisms without which many essential water-soluble nutrients like monosacharrides ,aminoacids and vitamins will be poorly absorbed. --the mechanism is thought to involve a component of the membrane called as the carrier. --the carrier,that binds reversible or non covalent with the solute molecules to be transported. --this carrier-solute complex transverse across the membrane to the other side where it dissociated & discharges the solute molecule--the carrier then returns to its original site to complete the cycle by accepting a fresh molecule of solute . --the carrier may be an enzyme or some other component of the membrane. --the important characteristics of carrier mediated transport are; 1.the transport process is structure specific(I.e. the carriers have affinity for and transfer a drug of specific chemical structure only ;generally the carriers have special affinity for essential nutrient...
