ii. Do you find any contraindication as far as the history of the patient is concerned?
Yes, I have found the “Isosorbide-5-mononitrate” as contraindicated drug in her prescription. Because it acts as a “vasodilator” .
iii. What are the reasons for contraindication?
On basis of lady’s case study, her heart muscle’s ability to supply blood to body is weak. As she is diabetic patient too, it can be concluded that congestive heart failure may be due to diabetes mellitus.
Being a partial agent as vasodilator, “Isosorbide-5-mononitrate” is useless and does not impart any its role in blood supply as compared to other drugs that contribute to relief anti-hypertensive condition to greater degree.
At this situation patient’s basic requirement is to fulfill body’s need for blood. This has been possible by using antihypertensive agent (except GLIBENCLAMIDE, METFORMIN, CLARITHROMYCIN).
iv. What alternative antibiotic would you recommend?
As the patient has completed her cycle of an antibiotic that is clarithromycin, another effective agents helps to recover her conditions are:
• Azithromycin (250mg, 500mg and 600mg)
• Erythromycin (250mg qid, 500mg bid)
v. How would you counsel the patient to modify lifestyle?
Counseling of patient:
• Say no to sugary juices.
• Avoid abuse alcohol.
• Take medicine at time.
• Walk daily.
