4.2 Drug Indication

Mysimba is indicated, as an adjunct to a reduced-calorie diet and increased physical activity, for the management of weight in adult patients (18 years) with an initial Body Mass Index (BMI) of

- 30 kg/m2 (obese), or

- 27 kg/m2 to < 30 kg/m2 (overweight) in the presence of one or more weight-related co morbidities (e. g. , type 2 diabetes, dyslipidaemia, or controlled hypertension)

Treatment with Mysimba should be discontinued after 16 weeks if patients have not lost at least 5% of their initial body weight.


5 Pharmacology and Biochemistry
5.1 MeSH Pharmacological Classification

Antidepressive Agents, Second-Generation

A structurally and mechanistically diverse group of drugs that are not tricyclics or monoamine oxidase inhibitors. The most clinically important appear to act selectively on serotonergic systems, especially by inhibiting serotonin reuptake. (See all compounds classified as Antidepressive Agents, Second-Generation.)


Smoking Cessation Agents

Substances that facilitate the cessation of tobacco smoking. (See all compounds classified as Smoking Cessation Agents.)


Cytochrome P-450 CYP2D6 Inhibitors

Drugs and compounds which inhibit or antagonize the biosynthesis or actions of CYTOCHROME P-450 CYP2D6. (See all compounds classified as Cytochrome P-450 CYP2D6 Inhibitors.)


Dopamine Uptake Inhibitors

Drugs that block the transport of DOPAMINE into axon terminals or into storage vesicles within terminals. Most of the ADRENERGIC UPTAKE INHIBITORS also inhibit dopamine uptake. (See all compounds classified as Dopamine Uptake Inhibitors.)
