Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

A Drug Utilisation Survey is performed to monitor and document the drug utilisation patterns of Samsca in routine medical practice.

A Post-Authorisation Safety Study is performed to collect information on the safety of Samsca when used in a real-life setting.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Drug Utilisation Survey The drug utilisation analysis will describe the number of prescriptions, their distribution between different medical specialties, and indication for use as compared to the SmPC, patient age and patient gender distributions on a prescription level. In addition, the indication for use will be further categorised as

* SIADH
* Non-SIADH hyponatraemia
* Non-Hyponatraemia

Post-Authorisation Safety Study

Sodium levels at baseline and rate of sodium correction under therapy will be analysed. Safety findings will be described. The number of all non-serious and serious adverse events and the relative frequencies will be analysed in consideration of the risk categories below:

* Renal safety
* Aquaresis-related adverse effects
* Serum sodium correction rate
* Glucose homeostasis
* Cardiovascular safety and hemodynamics
* Respiratory system
* Drug metabolism and drug interactions
* Drug exposure during pregnancy
* Paediatric safety

Subgroup analyses will be performed for all safety findings by indication subgroups (SIADH and other indications), subgroups according to SIADH-underlying diseases, age groups, hepatically impaired patients and renally impaired patients.
