Clenez 40TM is a beta2-adrenergic agonist. Stimulation of the beta2-adrenergic receptors on bronchial smooth muscle produces bronchodilation. However, clenbuterol, like other beta adrenergic agonists, can produce adverse cardiovascular and neurological effects, such as heart palpitations, muscle tremors, and nervousness. Activation of beta-adrenergic receptors also accounts for clenbuterol's ability to increase lean muscle mass and reduce body fat, although the downstream mechanisms by which it does so have yet to be clearly defined. After ingestion, clenbuterol is readily absorbed (70-80%) and remains in the body for awhile (25-39 hours). As a result of its long half life, the adverse effects of clenbuterol are often prolonged. |
