Types Of Absorption 1) Passive diffusion /simple diffusion 2) Filtration / Pore transport 3) Endocytosis . 4) Facilitated diffusion . 5) Active Transport 1) Passive diffusion /simple diffusion In this type of absorption the drug is transported from higher concentration to low concentration . 2) Filtration / Pore transport In this type of absorption the drug molecules are pass through the space between tow cells . 3) Endocytosis . In this type of absorption the cell membrane engulfs the drug molecule and take inside the cell . 4) Facilitated diffusion . In this type of absorption a carrier protein helps in the entering of drug inside the cell or membrane from higher concentration to low concentration , and no energy required in this process . 5) Active Transport In this type of absorption the carrier molecule combines with drug molecule and transports it inside the membrane , and energy is required in this process. Factors Affecting The Absorption Of Drugs 1)Physical State of Drug the liquids are better absorbed than solid medicaments . 2) Particle Size Smaller Particle size of drug absorbed easily . 3) Surface area of absorbing site Larger absorbing surface area provides greater absorption of drug . 4) Physical and mental state of the patient abnormal / disturbed physiological conditions affect the absorption of drugs like infection , fever , emotional upset etc. 5) Functional condition of GIT Increased peristaltic movement of GIT decreases the absorption of drugs . 6) pH of drug Acidic drugs are rapidly absorbed in stomach while basic drugs are rapidly absorbed in intestine . 7) Presence of food and other things in GIT.
