Testodex Enanthate 250 injection, for
intramuscular injection, contains testosterone enanthate which is insoluble in
water, very soluble in ether and soluble in vegetable oils. Androgens are
derivatives of cyclopentano-perhydrophenanthrene. Endogenous androgens are C-19
steroids with a side chain at C-17, and with two angular methyl groups.
Testosterone is the primary endogenous androgen. In their active form, all
drugs in the class have a 17-beta-hydroxy group. Esterification of the
17-beta-hydroxy group produces compounds (testosterone enanthate and
testosterone propionate) which have a longer duration of action and are
hydrolyzed in vivo to free testosterone. Androgens are steroids that develop
and maintain primary and secondary male sex characteristics. Endogenous
androgens are responsible for the normal growth and development of the male sex
organs and for maintenance of secondary sex characteristics. These effects
include the growth and maturation of prostate, seminal vesicles, penis, and
scrotum; the development of male hair distribution, such as beard, pubic, chest
and axillary hair; laryngeal enlargement, vocal chord thickening, alterations in
body musculature, and fat distribution. Drugs in this class also cause retention
of nitrogen, sodium, potassium, phosphorous, and decreased urinary excretion of
calcium. Androgens have been reported to increase protein anabolism and decrease
protein catabolism. Nitrogen balance is improved only when there is sufficient
intake of calories and protein. Androgens are responsible for the growth
spurt of adolescence and for the eventual termination of linear growth which is
brought about by fusion of the epiphyseal growth centers. In children, exogenous
androgens accelerate linear growth rates, but may cause a disproportionate
advancement in bone maturation. Use over long periods may result in fusion of
the epiphyseal growth center and termination of growth process. Androgens
have been reported to stimulate the production of red blood cells by enhancing
the production of erythropoietic stimulating factor. During exogenous
administration of androgens, endogenous testosterone release is inhibited
through feedback inhibition of pituitary luteinizing hormone (LH). At large
doses of exogenous androgens, spermatogenesis may also be suppressed through
feedback inhibition of pituitary follicle stimulating hormone (FSH).
