Mezoxia 160mg, Megestrol Acetate Tablets
Mezoxia 160mg is a formulation of Megestrol Acetate, a synthetic derivative of the naturally occurring hormone progesterone. It is primarily used as an appetite stimulant and for the treatment of certain cancers, especially hormone-sensitive cancers like breast and endometrial cancer. Additionally, it has been found effective in managing weight loss and cachexia (wasting syndrome) commonly associated with chronic illnesses like AIDS or cancer.
What is Mezoxia 160mg (Megestrol Acetate)?
Mezoxia contains Megestrol Acetate, a progestin (a type of hormone) that mimics the natural female hormone progesterone. While it is structurally related to female hormones, it has been widely repurposed for its anti-neoplastic and appetite-stimulating properties.
It is available as oral tablets, typically prescribed for conditions involving weight loss, loss of appetite, or certain hormone-dependent cancers. Mezoxia 160mg is a prescription medication, meaning it should be taken only under medical supervision.
How it Works / Mechanism of Action
Megestrol Acetate works through multiple mechanisms depending on the condition being treated:
Hormonal Modulation in Cancer:
- Megestrol has anti-estrogenic properties by binding to the body’s progesterone receptors.
- This blocks the growth of estrogen-sensitive tumors such as breast or endometrial cancer.
- It may also suppress adrenal function and reduce the production of other hormones that fuel cancer growth.
Appetite Stimulation:
- Megestrol increases neuropeptide Y levels in the brain, which is associated with increased hunger.
- It also appears to reduce pro-inflammatory cytokines, which are elevated in cachexia and suppress appetite.
- The overall result is increased appetite and weight gain, especially helpful in cancer or HIV/AIDS-related weight loss.
How to Use / Indications
Mezoxia 160mg is primarily used in the following conditions:
Cancer Treatment:
- Advanced breast cancer
- Endometrial cancer
Often used in palliative care settings when standard treatments fail or are not tolerated.
Appetite Stimulation and Weight Gain:
- HIV/AIDS-associated cachexia
- Cancer-induced anorexia and weight loss
- Geriatric weight loss and malnutrition
Off-label uses (used in some countries under medical supervision):
- Severe anorexia nervosa
- Menopausal symptoms (as hormonal therapy)
- Hot flashes in certain hormone therapies
