Simple or Passive Membrane Transport
This mechanism is mainly based on lipid degradation and concentration gradient, which is responsible for the membrane passage of the vast majority of drugs.
The permeability of membranes is very large. Water-loving molecules typically have high distribution coefficients while they are low in water-loving molecules. The velocity of the transport point is determined by the concentration gradient of the material across the membrane.
Molecules with weak acidity or alkali express membranes more rapidly than in non-displaced form.
However, water solubility is better for the displaced form. The medication must be in solution solution so that it is able to cross any membrane. This contrasting necessity of solubility in both water and fat is closely related to the absorption of the drug and poses a continuing challenge in pharmaceutical compositions.
