Anorectic
A name frequently used for diet medications that curb appetite.

DEXTROAMPHETAMINE
The d-form of AMPHETAMINE. It is a central nervous system stimulant and a sympathomimetic. It has also been used in the treatment of narcolepsy and of attention deficit disorders and hyperactivity in children. Dextroamphetamine has multiple mechanisms of action including blocking uptake of adrenergics and dopamine, stimulating release of monamines, and inhibiting monoamine oxidase. It is also a drug of abuse and a psychotomimetic.

Lipid

Hypertension
Higher blood pressure than normal. Diastolic blood pressure from 90 to 99 mm HG is considered mild hypertension; 100109, moderate hypertension; and 110 or greater, severe hypertension. Systolic blood pressure from 140 to 159 mm HG is considered mild hypertension; 160179, moderate hypertension; and 180 or greater, severe hypertension.
