Identification

Name
PH-284
Accession Number
DB05452
Description

PH-284 belongs to a new family of new chemical entities called vomeropherins. Vomeropherins are self-administered by the patient with a metered nasal spray, or nasal aerosol device so that they can bind to peripheral chemosensory receptors in the nasal passages. This binding produces neural impulses that are transmitted by specific pathways to the hypothalamic centre that directly and rapidly affect brain function. PH-284 is under investigation by Pherin and Organon for the treatment of anorexia nervosa, and loss of appetite and cachexia in cancer and AIDS patients.

Pharmacology

Indication

Investigated for use/treatment in anorexia and other conditions causing harmful weight loss. The manufacturer suggests it could be relevant for treatment of weight loss and the associated symptoms-- i.e., lack of energy, decrease in appetite, physical wasting, vulnerability to toxicity, and sometimes reduced life expectancy-- in patients with eating disorders, patients with advanced cancer, patients with AIDS, and patients experiencing loss of appetite due to aging, acute illness, or pregnancy.

Pharmacodynamics

Vomeropherins are self-administered by the patient with a metered nasal spray, or nasal aerosol device so that they can bind to peripheral chemosensory receptors in the nasal passages. This binding produces neural impulses that are transmitted by specific pathways to the hypothalamic centre that directly and rapidly affect brain function.

Mechanism of action

Vomeropherins bind to peripheral chemosensory receptors in the vomeronasal organ.
