However, they are made of hydrophilic polymers which can only incorporate hydrophilic drugs.
WebHydroxyl groups (-OH), found in alcohols, are polar and therefore hydrophilic (water liking) but their carbon chain portion is non-polar which make them hydrophobic. The molecule increasingly becomes overall more nonpolar and therefore less soluble in the polar water as the carbon chain becomes longer. Methanol has the shortest carbon chain of all alcohols … WebThis video is all about basics of absorption of drugs.The movement of drug from the site of administration into blood circulation is called Absorption of drug.
WebGenerally, hydrophilic molecules can be loaded into polymer nanospheres either by entrapping the drug within the polymer matrix (by adding the drug during nanoparticle formation) or by adsorption onto preformed nanocarriers. If the drug is encapsulated during manufacture, several parameters are involved.
