Clenbuterol is a sympathomimetic amine used as a bronchodilator for the management of respiratory conditions.
Clenbuterol belongs to the class of medicines known as bronchodilators. It is designed to open the airways in the lungs, making breathing easier for people with certain respiratory problems. In Hong Kong, Clenbuterol is available only with a prescription and can be found in products such as tablets, syrups, and inhalation solutions.
Clenbuterol itself is the name used for both the generic ingredient and the marketed product. In Hong Kong pharmacies you will see it listed as:

The effect usually begins within minutes for inhaled forms and a short time after oral doses, providing prompt relief during breathing problems.
