हाइड्रोकोडोन और क्लोरफेनिरामिन और टिकाग्रेलोर का इंटरैक्शन

Cytochrome P450 3A4 Interaction The concomitant use of Hydrocodone Polistirex and Chlorpheniramine Polistirex with all cytochrome P450 3A4 inhibitors may result in an increase in hydrocodone plasma concentrations, which could increase or prolong adverse drug effects and may cause potentially fatal respiratory depression.

Avoid the use of Hydrocodone Polistirex and Chlorpheniramine Polistirex in patients taking a CYP3A4 inhibitor or inducer [ see Warnings and Precautions (5.7) , Drug Interactions (7.2 , 7.3) ].

Concomitant use with CYP3A4 inhibitors (or discontinuation of CYP3A4 inducers) can result in a fatal overdose of hydrocodone.

Avoid the use of Hydrocodone Polistirex and Chlorpheniramine Polistirex in patients taking CYP3A4 inhibitors or inducers.

Avoid the use of Hydrocodone Polistirex and Chlorpheniramine Polistirex in patients who are taking a CYP3A4 inhibitor or inducer.

• Opioids: Decreased exposure to ticagrelor.

Opioids As with other oral P2Y 12 inhibitors, co-administration of opioid agonists delay and reduce the absorption of ticagrelor and its active metabolite presumably because of slowed gastric emptying [see Clinical Pharmacology (12.3) ] .

Consider the use of a parenteral anti-platelet agent in acute coronary syndrome patients requiring co-administration of morphine or other opioid agonists.
