Mi az a Tenuate Retard (Amfepramon)?
Tenuate Retard is the brand name for a modified-release (slow-release) formulation of Amfepramon, also known as Diethylpropion. It is a prescription appetite suppressant (anorectic) used as a short-term adjunct to dietary restriction and increased physical activity in the management of obesity in adults.
Amfepramon is a sympathomimetic amine — a class of medicines that stimulate the sympathetic nervous system. It is structurally related to amphetamine but has milder stimulant properties and a somewhat better tolerability profile. Despite this, it remains a controlled substance in many EU jurisdictions, subject to strict prescribing limitations.
The “Retard” formulation denotes a modified-release design that allows for once-daily dosing, providing more sustained appetite suppression throughout the day compared to immediate-release formulations.
Tenuate Retard is approved in certain EU member states as a short-term adjunct treatment for obesity in adults who:
- Have a BMI of 30 kg/m² or above, or
- Have a BMI of 27 kg/m² or above with at least one obesity-related comorbidity
- Have not achieved sufficient weight loss through diet and exercise alone
Hogyan hat a Tenuate Retard (Amfepramon)?
Amfepramon is a norepinephrine-dopamine releasing agent (NDRA). Its primary mechanism in weight management is appetite suppression via the central nervous system:
- Norepinephrine release: Amfepramon triggers the release of norepinephrine from presynaptic nerve terminals in the hypothalamus — the brain’s appetite regulation centre. Elevated norepinephrine levels activate adrenergic receptors that signal satiety and reduce appetite (anorectic effect).
- Dopamine release (minor): To a lesser extent, Amfepramon also increases dopamine release, which may contribute to reduced food reward motivation.
- Peripheral sympathomimetic effects: Amfepramon also has peripheral sympathomimetic effects — stimulating the heart and raising blood pressure — which account for some of its cardiovascular side effects and contraindications.
The appetite-suppressing effects of Amfepramon allow patients to adhere more easily to a reduced-calorie diet, supporting weight loss as part of a comprehensive obesity management programme.
Kinek ajánlott a Tenuate Retard (Amfepramon)?
Tenuate Retard is intended exclusively as a short-term adjunct treatment — not a standalone solution. It should only be used when prescribed within a structured obesity management programme that includes:
- Nutritional counselling and a reduced-calorie diet plan
- Increased physical activity
- Behavioural modification support
- Regular medical monitoring during treatment
Due to its significant contraindication list and potential for dependence, Tenuate Retard is considered a second- or third-line option, typically considered only when:
- Non-pharmacological measures have been insufficient
- GLP-1 receptor agonists (e.g., Semaglutide) or lipase inhibitors (e.g., Orlistat/Xenical) are contraindicated or not tolerated
- The patient meets all safety criteria and has no contraindications
Adagolás
For adults, the typical Tenuate Retard dosing schedule (modified-release tablet) is:
| Dose | Timing | Duration |
|---|---|---|
| 75 mg once daily | Mid-morning (approximately 10–14 hours before bedtime) | Maximum 12 weeks |
The modified-release tablet should be swallowed whole and not crushed or chewed. It is taken mid-morning to avoid interference with sleep.
Duration of treatment is strictly limited — typically a maximum of 12 weeks in EU member states. Treatment should be stopped if weight loss has not been satisfactory after 4 weeks at the maximum dose.
Mellékhatások
As a sympathomimetic stimulant, Amfepramon carries a range of cardiovascular, neurological, and psychiatric side effects.
Common side effects
- Elevated heart rate (tachycardia)
- Increased blood pressure
- Insomnia: Particularly if taken too late in the day
- Dry mouth
- Nervousness or restlessness
- Headache
- Dizziness
Less common side effects
- Palpitations
- Euphoria or mood elevation
- Constipation or diarrhoea
- Nausea
- Tremor
- Reduced libido or sexual dysfunction
Serious side effects
- Pulmonary arterial hypertension (PAH): A rare but serious condition involving elevated pressure in the arteries supplying the lungs. Anorectic agents including Amfepramon have been associated with PAH. Any new unexplained breathlessness during treatment should be evaluated urgently.
- Valvular heart disease: Association has been reported with sympathomimetic anorexics as a class, though evidence is less robust for Amfepramon than for some other agents.
- Dependence and withdrawal: Amfepramon has abuse potential. Tolerance develops with continued use, and abrupt discontinuation after prolonged use may cause withdrawal symptoms including fatigue and depression.
- Psychiatric effects: Anxiety, agitation, and in rare cases psychosis have been reported.

- Concurrent medications (particularly MAO inhibitors — absolute contraindication)
- Previous weight management attempts and outcomes
A folyamat a következő:
- Complete a weight management assessment: Provide full medical history, current medications, blood pressure history, and previous weight loss attempts.
- Orvosi felülvizsgálat: An independent EU-registered doctor reviews your assessment and determines whether Tenuate Retard or an alternative is appropriate.

Tenuate Retard is not a substitute for lifestyle changes. Dietary modification and increased physical activity are essential components of any obesity management programme. Weight loss achieved with appetite suppressants is typically not sustained after treatment stops without continued lifestyle adherence.

Frequently asked questions
- Mire használják a Tenuate Retard (Amfepramon)?
- Tenuate Retard (Amfepramon, also known as Diethylpropion) is a short-term appetite suppressant used as an adjunct to a reduced-calorie diet and lifestyle changes in the management of obesity. It is a sympathomimetic amine that works by stimulating the central nervous system to reduce appetite. It is approved in some EU member states for short-term use — typically 4 to 12 weeks — in adults with obesity who have not responded adequately to diet and exercise alone.
- Mennyi ideig can I take Tenuate Retard?
- Tenuate Retard is strictly indicated for short-term use only — typically a maximum of 12 weeks in most EU countries where it is approved. It is not intended as a long-term obesity treatment. This is because tolerance can develop (reducing effectiveness), and the risk of dependence increases with prolonged use. An independent doctor will determine the appropriate duration for your circumstances.
- Is Tenuate Retard a stimulant?
- Yes. Amfepramon is a sympathomimetic amine structurally related to amphetamine, though with milder stimulant properties. It works by increasing the release of norepinephrine (and to a lesser extent dopamine) in the hypothalamus, which suppresses appetite. Because of its stimulant mechanism, it can cause increases in heart rate and blood pressure, and has a potential for dependence and misuse — which is why it is strictly controlled and limited to short-term prescription use.
- Who should not take Tenuate Retard?
- Tenuate Retard has significant contraindications including cardiovascular disease (hypertension, heart failure, arrhythmias, coronary artery disease), history of stroke, pulmonary arterial hypertension, hyperthyroidism, history of drug dependence or substance misuse, pregnancy, and current or recent use of MAO inhibitors. A thorough medical assessment is essential before prescribing.
