Section 4.3 - Contraindications

·         The list of medicinal products which Norvir should not be co-administered with has been updated to include

o    Ranolazine (medical product class: antianginal)
Rationale: Increased plasma concentrations of ranolazine which may increase the potential for serious and/or life-threatening reactions (see section 4.5).

o    Lurasidone (medical product class: Antipsychotics/ Neuroleptics)
Rationale: Increased plasma concentrations of lurasidone which may increase the potential for serious and/or life-threatening reactions (see section 4.5).



Section 4.5 -  Interaction with other medicinal products and other forms of interaction

 

·    The following medicinal products have been added to the Interaction table:

o    Ranolazine (Due to CYP3A inhibition by ritonavir, concentrations of ranolazine are expected to increase.  The concomitant administration with ranolazine is contraindicated (see section 4.3).)

o    Lurasidone (Due to CYP3A inhibition by ritonavir, concentrations of lurasidone are expected to increase.  The concomitant administration with lurasidone is contraindicated (see section 4.3).)

·    Information relating to Fluticasone propionate aqueous spray has been updated to read:

Inhaled, injectable or intranasal fluticasone propionate, budesonide, triamcinolone

Systemic corticosteroid effects including Cushing's syndrome and adrenal suppression (plasma cortisol levels were noted to be decreased 86% in the above study) have been reported in patients receiving ritonavir and inhaled or intranasal fluticasone propionate; similar effects could also occur with other corticosteroids metabolised by CYP3A e.g., budesonide and triamcinolone.  Consequently, concomitant administration of ritonavir dosed as an antiretroviral agent or as a pharmacokinetic enhancer and these glucocorticoids is not recommended unless the potential benefit of treatment outweighs the risk of systemic corticosteroid effects (see section 4.4).  A dose reduction of the glucocorticoid should be considered with close monitoring of local and systemic effects or a switch to a glucocorticoid, which is not a substrate for CYP3A4 (e.g., beclomethasone).  Moreover, in case of withdrawal of glucocorticoids progressive dose reduction may be required over a longer period.

 4.4      Special warnings and precautions for use

 

The following warning has been added:

Riociguat

The concomitant use of ritonavir is not recommended due to potiential increase in riociguat exposure (see section 4.5).

 

Vorapaxar

The concomitant use of ritonavir is not recommended due to potential increase in vorapaxar exposure (see section 4.5).



 

 

4.5          Interaction with other medicinal products and other forms of interaction

The following interactions have been added:

 

Afatinib

20 mg, single dose

40 mg, single dose

40 mg, single dose

200 q12h/1h before

200 q12h/ co-administered

200 q12h/6h after

↑ 48%

 

↑ 19%

 

↑ 11%

↑ 39%

 

↑ 4%

 

↑ 5%

Serum concentrations may be increased due to Breast Cancer Resistance Protein (BCRP) and acute P‑gp inhibition by ritonavir.  The extent of increase in AUC and Cmax depends on the timing of ritonavir administration.  Caution should be exercised in administering afatinib with Norvir (refer to the afatinib SmPC).  Monitor for ADRs related to afatinib.

 

Ceritinib

Serum concentrations may be increased due to CYP3A and P‑gp inhibition by ritonavir.  Caution should be exercised in administering ceritinib with Norvir.  Refer to the ceritinib SmPC for dosage adjustment recommendations.  Monitor for ADRs related to ceritinib.

Vorapaxar

Serum concentrations may be increased due to CYP3A inhibition by ritonavir.  Coadministration of vorapaxar and Norvir should be avoided (refer to the vorapaxar SmPC).

Riociguat

Serum concentrations may be increased due to CYP3A and P-gp inhibition by ritonavir.  The coadministration of riociguat with Norvir is not recommended (see section 4.4 and refer to riociguat SmPC).
