How does Zimulti - rimonabant work?

The active substance in ZIMULTI, rimonabant, is a cannabinoid receptor antagonist. It works by blocking a specific type of receptor, cannabinoid receptors of type 1 (CB1). These receptors are found in the nervous system and are part of the system used by the body to control food intake. Receptors are also present in adipocytes (fat tissue).

What studies have been carried out on Zimulti - rimonabant?

The effects of ZIMULTI were first tested in experimental models before being studied in humans.

Four studies were performed on ZIMULTI in overweight and obese patients, for a total of about 7, 000 patients, whose weight at the start of the studies was on average between 94 and 104 kg. One study focused on patients with abnormal levels of blood fat and another on patients with type 2 diabetes.

The studies compared the effect of ZIMULTI with that of a placebo (a dummy treatment) on weight loss over a period between one and two years. One study also looked at how the loss could be maintained during the second year.

Four studies were also conducted on ZIMULTI, compared with placebo, as an aid to smoking cessation in over 7 000 patients and measuring the effects of the administration of the drug for 10 weeks (one year in one of the studies) on smoking cessation and on relapses in the following year.

What benefit has Zimulti - rimonabant shown during the studies?

After one year, all patients treated with ZIMULTI had lost more weight than people receiving placebo: on average, the loss was 4.9 kg more than placebo, except in the study on diabetic patients where the difference in loss of weight was 3.9 kg. The medicine has also reduced the risk of weight recovery.

Smoking cessation studies have not presented consistent results and the effect of ZIMULTI in this area is difficult to assess. The company has decided to withdraw the smoking cessation application, so ZIMULTI is not recommended as a smoking cessation aid

What are the risks associated with Zimulti - rimonabant?

During the studies, the most common side effects seen with ZIMULTI (affecting more than 1 in 10 patients) were nausea (feeling sick) and upper respiratory tract infections. For the full list of side effects reported with ZIMULTI, see the package leaflet.

ZIMULTI should not be used in patients who may be hypersensitive (allergic) to rimonabant or to any of the other ingredients of the medicine, or to breast-feeding women. ZIMULTI should not be used in patients with ongoing depression or who are treated with antidepressants, as it may increase the risk of depression, including suicidal thoughts in a small proportion of patients. Patients experiencing symptoms of depression should consult their doctor and perhaps stop treatment. ZIMULTI Caution should be used in combination with certain medicines such as ketoconazole or itraconazole (antifungal medicines), ritonavir (used against HIV infection), or telithromycin or clarithromycin (antibiotics).

Why has Zimulti - rimonabant been approved?

The Committee for Medicinal Products for Human Use (CHMP) concluded that ZIMULTI demonstrated its effectiveness in reducing the weight of obese or overweight patients with the associated risk factor (s). It decided that the benefits of ZIMULTI outweigh its risks when used, in addition to diet and exercise, for the treatment of obese and overweight patients with risk factors such as type 2 diabetes or dyslipidemia and has therefore it is recommended to issue the marketing authorization.
