It belongs to a class of medications called bronchodilators, which work by relaxing the muscles in the airways and increasing airflow to the lungs. Salbutamol is available in various forms, including inhalers, tablets, and liquid solutions.

Rectal mesalamine is prescribed to manage ulcerative colitis, which involves inflammation and ulceration in the colon and rectal lining. It is also used for proctitis, characterized by rectal inflammation, and proctosigmoiditis, which affects the rectum and sigmoid colon.
