This was meant to be a curative approach towards the blocking of norepinephrine using both the B1 and B2 adrenergic receptors (Neutel & Smith 1993, 184). This was after a break through in the research sector that saw a consensus arrived at given the fact that the research done by Mangano et al in 1996 brought clear knowledge on the way that non-cardiac surgery and those using the beta blockers responded upon receiving the atenolol. Patients reported a lower mortality overall and this meant that they were positively respondent to the drugs.

The American college of physicians in 1997 took these results and presented a guideline to preoperative risks management given the risk the patients were at with coronary artery (Julian 2001, 215). This was the real need to move on to the next generation drugs that worked more efficiently given the fact hat the drugs had to be improved in order to help the people have strong membrane stabilizing activity at high concentrations. It was a development that enabled doctors to come up with ways in which they could sort out the issues of the patients in an effective way (Olivia, 2001).

They were invented by Sir James Black in 1958 to upheaval the management of angina pectoris and were considered to be one of the most important contributions to clinical medicine and pharmacology of the 20th century (Olivia 2001). The research first started in Black’ s Glasgow Veterinary school laboratory where he noticed that there was an increase in the cases of patients suffering from angina pectoris and also a rise in the number of people dying due to heart attacks.

Taking conclusions from Dr. Claude, an American scientist, Black noticed that the scientist was working on a way in which he could increase the blood flow from non-cardiac sources and him he had to take a different approach to counter the effect of adrenaline in the heart. With this,   he came up with a way in which he could help in the production of drugs that could act as a block to the heart’ s adrenaline-responsive- beta receptors which were commonly referred to as beta-blockers for simplicity.
