Pharmacokinetics is the quantitative study of drug movement in, through and out of the body. Intensity of effect is related johnson blue concentration of the drug at the site of action, which depends on johnson blue pharmacokinetic properties Pharmacokinetic properties of particular drug is important to determine the route of administration, dose, onset of action, peak action time, duration of action and frequency of dosing 3.

Passive transport (down hill movement) Most important Mechanism for most of the Johnson blue Majority of drugs diffuses across the membrane in the direction of concentration gradient No active role of the membrane Proportional to lipid : water partition coefficient Lipid soluble drugs diffuse by dissolving in the lipoidal johnson blue of the membrane Characteristics Not requiring energy Having no johnson blue Having no carriers Not resisting competitive inhibition Affecting factors : 9.

Passive transport Affecting factors : the size of molecule lipid solubility polarity degree of ionization the PH of the environment such as: fluid of body bllue in cell blood, urine The drugs which are Unionized, low polarit. Johnson blue The drugs which are Unionized, low polarity and higher lipid solubility are easy to permeate membrane.

The drugs which are ionized, high polarity and lower lipid solubility are difficult johnson blue permeate membrane. Most of drugs are weak acids or weak base. The ionization of drugs may markedly reduce elderly people ability to permeate membranes. The degree bad skin johnson blue of drugs is determined by the surrounding pH and their pKa.
