Benefits of Celstrol Tablet

Treatment of Anorexia
Anorexia refers to a loss of appetite or reduced desire to eat. In patients with cancer or acquired immunodeficiency syndrome (AIDS) who experience loss of appetite, Celstrol 160 Tablet helps stimulate appetite, making it easier to consume regular meals and maintain adequate calorie intake. An improved appetite can support better nutritional intake, help reduce weakness, and aid in maintaining body weight during illness.
Treatment of Cachexia
Cachexia is a condition marked by significant weight loss, muscle wasting, and weakness due to chronic illness. In cancer- or AIDS-related cachexia, Celstrol 160 Tablet helps promote weight gain by improving appetite and increasing food intake. Supporting weight stabilization or gain helps improve strength, physical function, and overall nutritional status in patients experiencing disease-related wasting.
Treatment of significant unexplained Weight loss
In patients with cancer or AIDS who experience significant, unexplained weight loss, Celstrol 160 Tablet supports increased calorie intake and gradual weight gain. Weight restoration helps improve energy levels, reduce fatigue, and support overall physical well-being during treatment or illness.
