clenbuterol and Glycogen Storage Disease Type II

clenbuterol has been researched along with Glycogen Storage Disease Type II in 6 studies

Clenbuterol: A substituted phenylaminoethanol that has beta-2 adrenomimetic properties at very low doses. It is used as a bronchodilator in asthma.
clenbuterol : A substituted aniline that is 2,6-dichloroaniline in which the hydrogen at position 4 has been replaced by a 2-(tert-butylamino)-1-hydroxyethyl group.

Glycogen Storage Disease Type II: An autosomal recessively inherited glycogen storage disease caused by GLUCAN 1,4-ALPHA-GLUCOSIDASE deficiency. Large amounts of GLYCOGEN accumulate in the LYSOSOMES of skeletal muscle (MUSCLE, SKELETAL); HEART; LIVER; SPINAL CORD; and BRAIN. Three forms have been described: infantile, childhood, and adult. The infantile form is fatal in infancy and presents with hypotonia and a hypertrophic cardiomyopathy (CARDIOMYOPATHY, HYPERTROPHIC). The childhood form usually presents in the second year of life with proximal weakness and respiratory symptoms. The adult form consists of a slowly progressive proximal myopathy.
