Clinical Summary

A semisynthetic ergotamine alkaloid that is a dopamine D2 agonist. It suppresses prolactin secretion.

Therapeutic Applications

Bromocriptine is used alone or with other medications (such as levodopa) to treat Parkinson's disease. It can improve your ability to move and can decrease shakiness (tremor), stiffness, slowed movement, and unsteadiness. It may also decrease the number of episodes of not being able to move (on-off syndrome). Bromocriptine is also used to treat high levels of a certain hormone made by the body (prolactin). High levels of prolactin may cause problems such as unwanted breast milk, missed/stopped periods, difficulty becoming pregnant, decreased sperm production, and decreased sexual ability. Bromocriptine may be used to treat a type of tumor which causes the high levels of prolactin (prolactin-secreting adenomas). It can help to reduce the tumor size. Bromocriptine is not recommended for stopping unwanted breast milk after pregnancy, miscarriage, or abortion because of possible serious side effects (such as high blood pressure, seizure, heart attack, stroke). Bromocriptine is also used to treat high levels of growth hormone (acromegaly). Bromocriptine is an ergot medication that works by acting like a certain natural substance (dopamine) in the brain. It also prevents the release of certain hormones (growth hormone, prolactin). Bromocriptine can lower these hormone levels, but it does not cure the causes of the increased levels.

Therapeutic Applications

This combination medication is used to treat symptoms of Parkinson's disease or Parkinson-like symptoms (such as shakiness, stiffness, difficulty moving). Parkinson's disease is thought to be caused by too little of a naturally occurring substance (dopamine) in the brain. Levodopa changes into dopamine in the brain, helping to control movement. Carbidopa prevents the breakdown of levodopa in the bloodstream so more levodopa can enter the brain. Carbidopa can also reduce some of levodopa's side effects such as nausea and vomiting.

With atrial fibrillation, part of the heart does not beat the way it should. This can lead to blood clots forming, which can travel to other parts of your body (such as the lungs or legs) or increase your risk for stroke. In the United States, apixaban is also approved to treat certain types of blood clots (deep vein thrombosis-DVT, pulmonary embolus-PE) and to prevent them from forming again. Apixaban is an anticoagulant that works by blocking certain clotting proteins in your blood.

Clinical Summary

An orally active 3-OXO-5-ALPHA-STEROID 4-DEHYDROGENASE inhibitor. It is used as a surgical alternative for treatment of benign PROSTATIC HYPERPLASIA.

Therapeutic Applications

Finasteride is used to shrink an enlarged prostate (benign prostatic hyperplasia or BPH) in adult men. It may be used alone or taken in combination with other medications to reduce symptoms of BPH and may also reduce the need for surgery. Finasteride may improve symptoms of BPH and provide benefits such as decreased urge to urinate, better urine flow with less straining, less of a feeling that the bladder is not completely emptied, and decreased nighttime urination. This medication works by decreasing the amount of a natural body hormone (DHT) that causes growth of the prostate. Finasteride is not approved for prevention of prostate cancer. It may slightly increase the risk of developing a very serious form of prostate cancer. Talk to your doctor about the benefits and risks. Women and children should not use this medication.

Dataset Methodology & CMS Source Information

This analytical profile maps public infrastructure records sourced directly from official **Centers for Medicare & Medicaid Services (CMS)** public data releases. The statistics above track documented pharmaceutical treatment trends assigned to beneficiaries specifically under federal public programs. Evaluating the prescriptive footprints of clinical practitioners like HELENA CHANG CHUI M.D. provides transparency into local medical care patterns within Los Angeles, CA.

Key Learning Objectives for this Profile:

  • Prescribing Frequencies: Track and evaluate the volume metrics of specific brand-name and generic medical formulas chosen by this provider over time.
  • Clinical Focus Areas: Identify how the provider distributes therapeutic selections across medical care options to gain insight into their true day-to-day **Neurology** practice concentrations.
  • Program Cost Awareness: Review the calculated total systemic drug costs and raw transactional volumes linked to these orders to better anticipate network insurance coverage structures.
