== Abarelix ==

'''Abarelix''' (pronounced as ah-buh-RE-lix) is a synthetic decapeptide and a potent, highly selective antagonist of [[gonadotropin-releasing hormone]] (GnRH) receptors. It is used in the treatment of advanced symptomatic [[prostate cancer]].

=== Etymology ===

The term "Abarelix" is derived from the combination of the prefix "aba-", which is used in organic chemistry to denote a substituent in a position remote from the functional group, and "relix", which is a common suffix for GnRH antagonists.

=== Usage ===

Abarelix is used to treat symptoms of advanced prostate cancer. It works by reducing the amount of [[testosterone]] that the body makes. This helps slow or stop the growth of cancer cells and helps relieve symptoms such as painful/difficult urination.

=== Dosage and Administration ===

Abarelix is administered by a healthcare professional as an injection into the muscle of the buttocks once every month, or as directed by the doctor. The dosage is based on the patient's medical condition and response to treatment.

=== Side Effects ===

Common side effects of Abarelix include hot flashes, breast tenderness/swelling, injection site reactions, dizziness, and headache. Serious side effects include bone pain, muscle weakness, and difficulty urinating.
