In the elliptical orbit, the center of mass of the orbiting-orbited system is at one focus of both orbits, with nothing present at the other focus. As a planet approaches periapsis, the planet will increase in speed, or velocity.
Drugs that cause hyponatremia include: 1  Diuretics: Thiazides, bumetanide, indapamide, ethacrynic acid, furosemide. 2  Antidepressants: Selective serotonin reuptake inhibitors, tricyclic antidepressants (amitriptyline, protriptyline, desipramine), monoamine oxidase inhibitors, venlafaxine.
Although it is possible that hydrochlorothiazide could cause hyponatremia, it is striking that only one day after the addition of valproic acid symptoms occur. No further details were reported. Conclusion In the Lareb database 359 reports of valproic acid are present, of which six concern hyponatremia and/or SIADH. The number of reports in the Lareb and the WHO database and the case reports in literature support the association.
