WHAT SAMSCA IS AND WHAT IT IS USED FOR
Samsca, which contains the active substance tolvaptan, belongs to a
group of medicines called
vasopressin antagonists. Vasopressin is a hormone that helps prevent
the loss of water from the body
by reducing urine output. Antagonist means that it prevents
vasopressin having its effect on water
retention. This leads to a reduction in the amount of water in the
body by increasing urine production
and as a result it increases the level or concentration of sodium in
your blood.
Samsca is used to treat low serum sodium levels in adults. You have
been prescribed this medicine
because you have a lowered sodium level in your blood as a result of a
disease called “syndrome of
inappropriate antidiuretic hormone secretion” (SIADH) where the
kidneys retain too much water. This
disease causes an inappropriate production of the hormone vasopressin
which has caused the sodium
levels in your blood to get too low (hyponatremia). That can lead to
difficulties in concentration and
memory, or in keeping your balance.

CLINICAL PARTICULARS
4.1
THERAPEUTIC INDICATIONS
Samsca is indicated in adults for the treatment of hyponatremia
secondary to the syndrome of
inappropriate antidiuretic hormone secretion (SIADH).
4.2
POSOLOGY AND METHOD OF ADMINISTRATION
Due to the need for a dose titration phase with close monitoring of
serum sodium and volume status
(see section 4.4), treatment with Samsca has to be initiated in
hospital.
3
Posology
Tolvaptan has to be initiated at a dose of 15 mg once daily. The dose
may be increased to a maximum
of 60 mg once daily as tolerated to achieve the desired level of serum
sodium.
For patients at risk of overly rapid correction of sodium e.g.,
patients with oncological conditions, very
low baseline serum sodium, taking diuretics, or taking sodium
supplementation a dose of 7.5 mg
should be considered (see section 4.4).
During titration, patients must be monitored for serum sodium and
volume status (se
