Microsomal Lomitapide Increased plasma concentrations of lomitapide
triglyceride transfer (see section 4.5).
protein (MTTP)
inhibitor

(see section 4.4. and 4.5).
Sildenafil Contraindicated when used for the treatment of
pulmonary arterial hypertension (PAH) only.
Increased plasma concentrations of sildenafil.
Thereby, increasing the potential for sildenafil-
associated adverse events (which include
hypotension and syncope). See section 4.4 and
section 4.5 for co-administration of sildenafil in
patients with erectile dysfunction.
Vardenafil Increased plasma concentrations of vardenafil
(see section 4.4. and 4.5).
Sedatives/hypnotics Clorazepate, diazepam, Increased plasma concentrations of clorazepate,
estazolam, flurazepam, diazepam, estazolam, flurazepam, oral
oral midazolam and midazolam and triazolam. Thereby, increasing
triazolam the risk of extreme sedation and respiratory
depression from these agents. (For caution on
parenterally administered midazolam, see
section 4.5).

Sedatives/hynoptics
Clorazepate, diazepam, estazolam, Ritonavir co-administration is likely to result in increased plasma concentrations of
flurazepam, oral and parenteral clorazepate, diazepam, estazolam and flurazepam and is therefore contraindicated
midazolam (see section 4.3).
Midazolam is extensively metabolised by CYP3A4. Co-administration with
ritonavir may cause a large increase in the concentration of this benzodiazepine. No
medicinal product interaction study has been performed for the co-administration of
ritonavir with benzodiazepines. Based on data for other CYP3A4 inhibitors, plasma
concentrations of midazolam are expected to be significantly higher when
midazolam is given orally. Therefore, ritonavir should not be co-administered with
orally administered midazolam (see section 4.3), whereas caution should be used
with co-administration of ritonavir and parenteral midazolam. Data from
concomitant use of parenteral midazolam with other protease inhibitors suggest a
possible 3 – 4 fold increase in midazolam plasma levels. If ritonavir is
co-administered with parenteral midazolam, it should be done in an intensive care
unit (ICU) or similar setting which ensures close clinical monitoring and appropriate
medical management in case of respiratory depression and/or prolonged sedation.
Dosage adjustment for midazolam should be considered, especially if more than a
single dose of midazolam is administered.
