Such as, acidic urine in individuals with urinary tract infections can enhance the excretion of weakly acidic drugs like penicillin.

Aged are reasonably intolerant to digitalis.

They are more vulnerable to create postural instability, giddiness and mental confusion. In general, the incidence of adverse drug reactions is much higher in the aged.

Plasma drug concentration increases with extent of absorption; the maximum (peak) plasma concentration is attained when drug elimination fee equals absorption amount. Bioavailability determinations depending on the height plasma focus might be misleading mainly because drug elimination commences the moment the drug enters the bloodstream.

A continuous variation with Gaussian frequency distribution is viewed in the situation of most drugs. Furthermore, there are several precise genetic defects which lead to discontinuous variation in drug responses, e.g.—
