<prompt> True statement about the drug of Administration is80 bioavailability by I.V. injectionI.M. administration needs sterile techniqueI.D. injection produce local tissue necrosis and irritationInhalation route produces delayed systemic bioavailability  <response>: 1100. bioavailability is seen in case of IV route. 2sterile technique is needed in case of I.V. and I.M. administration. 3Irritation and loal tissue necrosis is seen in case of imetable routes like intramuscular or s.c. route. 4In inhalational route, absorption of drugs takes place.from vast suaces of alveoli-so bioavailability is high and action is very rapid.
