Blood Marker Tests. Your doctor may order blood tests for cancer/tumor markers to detect cancer activity in the body. Proteins and circulating tumor cells are two types of markers that can be measured. A cancer tumor often produces a specific protein in the blood that serves as a marker for the cancer.
Zolpidem, sold as the brand name Ambien among others, is a sedative primarily used for the treatment of trouble sleeping. It usually works within 15 minutes, and has a short half-life of two to three hours. Zolpidem has not adequately demonstrated effectiveness in maintaining sleep, unless delivered in a controlled-release (CR) form.
Ambien vs. Lunesta. Ambien (Zolpidem) and Lunesta (Eszopiclone) are prescription nonbenzodiazepine hypnotic drugs used to treat insomnia. They have comparable efficacy, but both also have the potential to become addictive with serious risks. Unlike Ambien, Lunesta is not restricted to short-term use.
