Conjugated estrogens are approved for moderate to severe vasomotor symptoms of menopause, vulvovaginal atrophy due to menopause, osteoporosis prevention in postmenopausal women at significant risk, and primary ovarian failure or female hypo… Japan classifies medicines into prescription drugs (医療用医薬品) and OTC drugs (一般用医薬品), the latter further divided into pharmacist-only (第1類) and self-service classes. The Ministry of Health, Labour and Welfare (MHLW) sets the regulatory framework; PMDA reviews safety and efficacy.
