Ventisal-L is a bronchodilator containing Levosalbutamol, a single isomer beta-2 adrenergic agonist. It differs from racemic salbutamol by eliminating the (S)-salbutamol isomer, leading to improved efficacy and reduced side effects. Levosalbutamol works by stimulating beta-2 receptors in the bronchial smooth muscles, causing relaxation and dilation of the airways, which eases breathing
