KRIMSON 35-THE DRUG MOSTLY USED TO TREAT PCOD
CYPROTERONE ACETATE AND ETHINYLOESTRDIOL TABLETS:
Each film coated tablet contains:
cyproterone acetate BP 2mg
ethinyloestradiol IP 0.035mg
it combines with cyproterone acetate ,a potent antiandrogen and ethinyl oestradiol,a semisynthetic derivetive of oestradiol.
MECHANISM OF ACTION;
The function of sebaceous glands is mostly dependent on androgens.Androgens stimulate the mitotic activity in the sebaceous glands ,fibroblasts and hair follicles.seborrhea,the increased production of sebum ,plays an important role in the genesis of acne.
cytoproterone acetate contained in krimson-35 blocks androgen receptors.it also reduces androgen synthesis both by negative feedback effect on the hypothalamo pituitary ovarian system and by the inhibition of androgen synthesizing enzymes.
The stimulating effect of male sex hormones on androgen dependant structures and functions is weakened or abolished by cytoproterone acetate.
It inhibits the influence of androgens and reduces the activity of sebaceous gland.apart from this, it also has a progestational action.
Ethinyloestrdiol in the combination inhibits ovulation and changes the cervical mucus and the endomerium rendering them unfavourable for sperm penetration and nidation of a fertilized ovum respectively........
Although it acts as a oral contraceptive,it is not recommended in women solely for contraception.
