However, some nonbasic psychotherapeutic drugs chlorpromazine, imipramine, amines, such as the herbicide paraquat, also spiroperidol, and nortriptyline, is becoming apparent. Although bone is a relatively inert tissue, certain physiological and pathological conditions, such it can accumulate such substances as tetracyas injury, stress, surgery, trauma, rheumatoid arthritis, clines, lead, strontium, and the antitumor agent and celiac disease. These substances may accumulate in bone by absorption onto the bone crystal surface and eventually be incorporated into the crystal lattice. Lead can substidrugs will be either considerably higher or considerably tute for calcium in the bone crystal lattice, relower in particular tissues than could be predicted on sulting in bone brittleness. This obserreservoir for the slow release of toxic subvation is demonstrated in the following examples: stances, such as lead and cisplatin. The kidney also contains a protein, metallothionein, that has a high afﬁnity for Blood-Brain Barrier metals. This protein is responsible for the renal accumulation of cadmium, lead, and mercury.

Placebo: It is a Latin word meaning I shall please and it is a tablet looking exactly like the active treatment but containing no active component. It refers originally to substances merely to please the patient when no specific treatment was available. Adverse drug reactions: the drugs that produce useful therapeutic effect may also produce unwanted or toxic effects. If is always an exaggeration of its pharmacological actions and some times it is predictable. The adverse effects are 1)Side effects 2)untoward effects 3)allergic reactions 4)idiosyncratic reactions and 5)teratogenic effects. They are undesirable and if very severe, may necessitate the cessation of treatment. When an individual has been sensitized to an antigen (allergen) further contact with that antigen can some times lead to tissue damaging reactions. With the increasing knowledge of pharmacogenetics, many idiosyncratic reactions have been found to be genetically determined. The best known example is thalidomide which results in early easily recognizable abnormalities such as absent or grossly abnormal limbs. Other drugs with teratogenic potential are androgens, steroids, anti convulsants, anti neoplastic drugs, cortisone, lithium, pencillamine, tricyclic antidepressants and warfarin. V) Development and evaluation of new drugs: the ultimate aim of pharmacological studies in animals is to find out a therapeutic agent suitable for clinical evaluation in man. The administration of biologically active agent to human beings is associated with an element of risk, which cannot be predicted by even the most careful and exhaustive animal experiments. Scientists all over the world are in a continuous effort to develop new drugs although drug development is an extremely technical and enormously expensive operation. Research and development of new drugs have been done under strict government regulations which have greatly increased over the past couple of decades. The aim of the preclinical development phase for a potential new medicine is to explore the drug’s efficacy and safety before it is administrated to patients.
