	~~==Medical uses==~~		'''Megestrol caproate''' is a [[synthetic progestin]] used in [[hormone therapy]]. It is a derivative of [[megestrol]], a [[progesterone]] analog, and is primarily utilized for its [[progestogenic]] effects.
	Megestrol caproate is ~~primarily~~ used ~~to treat loss of appetite and~~ [[~~weight loss~~]] ~~in people with~~ [[~~AIDS~~]] ~~and~~ [[~~cancer~~]]~~. It~~ is ~~also used in the treatment of breast cancer and~~ [[~~endometrial cancer~~]].

	==~~Side effects~~==		==Pharmacology==
	~~Common side effects~~ of ~~megestrol~~ caproate ~~include weight gain~~, [[~~edema~~]], [[~~thromboembolism~~]], and [[~~menstrual irregularities~~]]. ~~Rare but serious side effects include~~ [[~~adrenal insufficiency~~]] and [[~~Cushing's syndrome~~]].
			===Mechanism of Action===
			Megestrol caproate functions by binding to the [[progesterone receptor]], mimicking the effects of natural progesterone. This interaction leads to changes in the [[endometrium]] and influences the [[hypothalamic-pituitary-gonadal axis]], ultimately affecting [[ovulation]] and [[menstrual cycle]] regulation.

			===Pharmacokinetics===
			The pharmacokinetic profile of megestrol caproate involves its absorption, distribution, metabolism, and excretion. It is administered via [[intramuscular injection]], allowing for a slow release and prolonged action. The drug is metabolized in the [[liver]] and excreted primarily through the [[urinary system]].

	==~~Pharmacology~~==		==Clinical Uses==
	Megestrol caproate is ~~a synthetic~~ [[~~progestogen~~]] ~~and acts as an~~ [[~~agonist~~]] of ~~the~~ [[~~progesterone receptor~~]]~~, the biological target~~ of [[~~progesterone~~]]~~. It has strong anti-~~[[~~gonadotropic~~]] ~~effects and can inhibit~~ [[~~fertility~~]] ~~and suppress~~ [[~~sex hormone~~]] ~~production.~~		Megestrol caproate is used in various clinical settings, including:

			* [[Hormone replacement therapy]]
			* [[Contraception]]
			* Treatment of [[endometriosis]]
			* Management of [[menstrual disorders]]

			==Side Effects==
			Common side effects of megestrol caproate include:

			* [[Weight gain]]
			* [[Fluid retention]]
			* [[Mood changes]]
			* [[Nausea]]

	==~~History~~==		==Synthesis==
	~~Megestrol~~ caproate ~~was first described in 1959 and was introduced for medical use in 1963. It was~~ the ~~first progestin~~ to ~~be used in cancer treatment and was also~~ the ~~first to be used as an appetite stimulant~~.		The synthesis of megestrol caproate involves the chemical modification of megestrol, incorporating a caproate ester group to enhance its pharmacological properties. This modification increases the drug's [[lipophilicity]], allowing for a longer duration of action.

	==~~Society and culture~~==		==Related Compounds==
	Megestrol caproate is ~~marketed under a variety of brand names including~~ [[~~Megace~~]] and [[~~Ovaban~~]] and ~~is available as a generic medication~~.		Megestrol caproate is related to other progestins such as [[medroxyprogesterone acetate]] and [[norethindrone]]. These compounds share similar mechanisms of action but differ in their chemical structure and clinical applications.
