Vyvanse 30mg, 50mg


As a central systema nervosum stimulant, lisdexamfetamine is employed as an adjunct within the treatment
of attention deficit hyperactivity disorder (ADHD). As a prodrug, lisdexamfetamine was
specifically designed as an abuse-resistant product. After oral administration and absorption,
enzyme hydrolysis following contact with red blood cells will break lisdexamfetamine into Llysine,
a present essential aminoalkanoic acid and active d-amphetamine which is
responsible for the drug’s pharmacological activity.

Chemical properties

Lisdexamfetamine dimesylate has low lipophilicity (logP-1.76) and high aqueous solubility within a biologically relevant pH range of 1-8. Therefore, It should be stored at 25°C (77°F) with excursions permitted to 15-30°C (59-86°F).
As such, Lisdexamfetamine should be dispensed during a tight, light-resistant container.

General pharmacology of Vyvanse
Lisdexamfetamine may be a prodrug and an inactive molecule until ingestion. After oral administration, enzyme hydrolysis following contact with red blood cells will break lisdexamfetamine into L-lysine, a present essential aminoalkanoic acid and active damphetamine which is liable for the drug’s activity. However, Gastrointestinal pH doesn’t alter this conversion and thus the attachment of the L-lysine slows down the relative amount of d-amphetamine available to the blood stream and therefore the CNS.

Lisdexamfetamine PO is rapidly absorbed via the alimentary canal in animals. It attains a maximum plasma concentration -0.25-3 h. Studies in vitro suggest lisdexamfetamine may be a substrate for the peptide transport protein PEPT1 and perhaps also PEPT2.

Adverse reactions of vyvanse in humans
To begin with, When tested in subjects with a history of stimulant abuse, doses of 50-150 mg oral lisdexamfetamine dose-ependently. Equally, increased systolic and diastolic vital sign , and pulse compared to placebo and therefore the 150 mg dose of lisdexamfetamine produced higher changes than 40 mg d-amphetamine.
