Overview
The mainstay of therapy for endometriosis is pain management and regression of endometrial lesions. NSAIDs are useful for pain management. There are many therapeutic options available to reduce the size of endometrial lesions. Gonadotrophin releasing hormone agonists and danazol are widely used. Continuous oral contraceptive pill use is also helpful in patients with mild to moderate endometriosis.
Medical Therapy
The treatment of endometriosis is a combination of medical and surgical therapy based on the extent of the disease, the age of the patient, and the desire of the patient to conceive. The primary goal of medical therapy is the symptomatic improvement of pain and regression of the endometrial lesions.[1][2][3]
- Endometriosis occurs due to increased levels of estrogen. This may be a result of excess production in the body or exogenous estrogen intake. Therefore, the primary goal of medical therapy is to shut off the estrogen supply which is essential for the growth of the endometrial lesions.[4]
- Treatment of patients with mild to moderate pain (pain is not couse of absence) is nonsteroidal anti-inflammatory drugs (NSAIDs).[5]
- COX-2 inhibitors (celecoxib, rofecoxib, and valdecoxib) are avoided for patients desire pregnancy.[6][7]
- Among patients without medical contraindications, the best treatment is combination of estrogen-progestin contraceptives combined and NSAID.[8]
- Progestin-only contraceptive pills such as norethindrone 0.35 mg (once daily) combined with an NSAID is used among patient who can not use estrogen therapy.[9]
- Intramuscular injection of medroxyprogesterone acetate (MPA) 150 mg can helpful every three months.[10]
- Subcutaneous injection of medroxyprogesterone acetate (MPA) 104 mg can helpful every three months.[10]
- Norethindrone acetate 5 mg can be used by mouth daily (the dose can range from 2.5 mg to 15 mg daily).[11]
- Side effects of progestin treatment is:[12]
- Irregular uterine bleeding
- Spotting
- Amenorrhea
- Weight gain
- Mood changes
- Bone loss
- Reduction in high-density lipoprotein (HDL) cholesterol
- Increases in low-density lipoprotein (LDL) cholesterol and triglycerides
- There are several therapeutic agents available to decrease estrogen production. The following table is a description of different therapeutic agents available for the treatment of endometriosis.
| Drug Class | Drugs | Duration of therapy | Mechanism of Action | Side effects of therapy |
|---|---|---|---|---|
| Gonadotrophin releasing hormone agonists | Leuprolide acetate | 3.75 mg intramuscularly once per month OR
11.25-mg depot injection every 3 months |
|
|
| Nafarelin acetate | Nasal spray dose of one spray 200 μg twice a day | |||
| Goserelin acetate | 3.6 mg every 28 days in a biodegradable subcutaneous implant | |||
| Elagolix | 150 mg once daily for up to 24 months or 200 mg twice daily for up to 6 months | |||
| Oral contraceptive pills | Low dose estrogen and high dose progesterone pills | Continuous therapy for a duration of 6 to 12 months | Feedback inhibition of FSH and LH |
|
| Synthetic steroid | Danazol | 200mg to 400mg orally per day for 6 to 9 months | Produces a hypoestrogenic and hyperandrogenic effect and induces atrophic changes in the endometrium |
|
| Progestogens only | Medroxyprogesterone acetate | 20 to 30 mg orally per day | Feedback inhibition of FSH and LH |
|
| Depo-medroxyprogesterone acetate | 150 mg intramuscularly every 3 months | |||
| Aromatase inhibitors[13] | Anastrozole | 1 mg once daily | Inhibition of aromatase expressed in the endometriomas resulting in decreased estrogen levels |
|
| Letrozole | 2.5 mg once daily |
Pain Management
Nonsteroidal anti-inflammatory drugs are useful for the control of pain and help to control the amount of bleeding when used in combination with oral contraceptive pills.[14]
