greetings from healthcaremagic.com
I am Dr Sourav Chakraborty and i will be helping you with your query.
As i can deduce from your history , you mother have been given some medicine for hear cardiac ailments following which she has developed itching / allergic reactions. However your history is incomplete for me to come to a significant conclusion.
I need to know which drug your dermatologist
has pointed out as the" culprit one "
And who told you to stop Rancad/ ranolazine her cardiologist or the dermatologist ?
Since you have not revealed such information i will try to list out significant possible interactions of regular drugs used in acute coronary syndrome
1) Ranolazine/Rancad is known to interact with atorvastatin
and increase the concentration of atorvastatin and hence increases the chance of thrombocytopenia
and acute renal failure
. Few patients do report rarely itching with atorvastatin but more so with fluvastatin, rosuvastatin, and simvastatin.
2) Ranolazine/Rancad will increase the level or effect of metoprolol/ beta blocker
I do believe changing the brand of statin /atorvastatin for your mother can help solve the problem or consult with her cardiologist.
Also your mother is showing promising improvement in her cardiac ailments then i do not advocate pausing her cardiac drugs.
Hope i have been able to help you. Take care.
