Generic Cycrin Information

Introduction

Cycrin is a prescription medication that contains the synthetic progestogen medroxyprogesterone. It is classified within the therapeutic groups of women’s health and general health, and is used for several hormone‑related conditions. In Hong Kong, Cycrin is regulated by the Department of Health and is only dispensed with a valid prescription. The drug’s primary purpose is to provide progestogenic activity that can substitute for naturally occurring progesterone, supporting menstrual regulation, contraception, and certain endocrine disorders. Secondary uses include treatment of endometrial hyperplasia and management of specific hormone‑dependent cancers, where clinical guidelines endorse medroxyprogesterone as an evidence‑based option.

What is Cycrin?

Cycrin is a oral formulation of medroxyprogesterone acetate (MPA), a synthetic analogue of the natural hormone progesterone. It is manufactured by several licensed pharmaceutical companies that market the product under the Cycrin brand name for the Hong Kong market. Medroxyprogesterone belongs to the class of progestins, which mimic the biological activity of endogenous progesterone. Well‑known brand names that contain the same active compound include Depo‑Provera, Provera, and Prempro; these are often referenced in international clinical literature. Cycrin delivers the same therapeutic molecule at a dosage strength that conforms with local prescribing standards, offering a locally available option for patients who require progestogenic therapy.

How Cycrin Works

Medroxyprogesterone exerts its effect by binding to progesterone receptors (PR) in target tissues such as the endometrium, breast, and hypothalamic‑pituitary axis. Activation of these receptors leads to:

• Suppression of gonadotropin release (LH and FSH), which reduces ovarian estrogen production and stabilizes the menstrual cycle.
• Induction of endometrial decidualization, making the uterine lining less receptive to implantation and thereby providing contraceptive protection.
• Anti‑estrogenic activity in breast tissue, which can slow the growth of estrogen‑dependent tumors.

Pharmacokinetically, medroxyprogesterone is absorbed rapidly after oral ingestion, reaching peak plasma concentrations within 2–4 hours. It is extensively bound to plasma proteins and metabolized primarily by hepatic CYP3A4 enzymes. The terminal elimination half‑life ranges from 12 to 17 hours, supporting once‑daily dosing for most indications. Clearance is modestly reduced in hepatic impairment, prompting dose adjustments in such patients.

Conditions Treated with Cycrin

• Contraception (progestin‑only oral contraceptive) – Cycrin prevents ovulation and alters cervical mucus, offering a reliable, hormone‑based birth control method.
• Irregular menstrual cycles / amenorrhea – By supplying exogenous progesterone, Cycrin stabilizes the endometrial cycle and restores regular bleeding patterns.
• Endometrial hyperplasia (non‑cancerous thickening of the uterine lining) – Progestogenic therapy counteracts estrogen‑driven proliferation, reducing the risk of progression to carcinoma.
• Hormone replacement therapy (HRT) for menopausal symptoms – When combined with estrogen, medroxyprogesterone protects the endometrium from estrogen‑induced overgrowth.
• Management of certain hormone‑dependent cancers – In selected breast or endometrial cancers, medroxyprogesterone provides anti‑estrogenic effects that can be incorporated into multidisciplinary treatment plans.

In Hong Kong, the prevalence of menstrual disorders and the demand for reliable contraception make Cycrin a frequently prescribed medication. Local epidemiological data from the Hong Kong Hospital Authority indicate that over 15 % of women of reproductive age seek medical management for irregular cycles, underscoring the clinical relevance of progestin therapy.

Patient Groups Most Likely to Benefit

• Premenopausal women requiring contraception, especially those who cannot tolerate estrogen‑containing formulations (e.g., migraine with aura, hypertension).
• Women with oligomenorrhea or amenorrhea where a progestin‑only regimen is preferred to re‑establish cyclic bleeding.
• Postmenopausal women using combined HRT where a progestin component is required to protect the uterine lining.
• Patients with diagnosed endometrial hyperplasia who need a non‑surgical, medically supervised treatment.
• Certain breast or endometrial cancer patients under oncologic supervision where medroxyprogesterone is part of a hormone‑targeted protocol.

Contra‑indications include known hypersensitivity to medroxyprogesterone, active thromboembolic disease, uncontrolled hypertension, and current or recent (within 4 weeks) estrogen‑dependent malignancy. Caution is advised in liver disease, diabetes, and patients with a history of mood disorders, as progestins can influence metabolic and psychological parameters.

Risks, Side Effects, and Interactions

Common

• Nausea or mild gastrointestinal upset
• Headache or dizziness
• Breast tenderness or enlargement
• Irregular spotting or breakthrough bleeding
• Weight gain (typically modest)

Rare

• Depressed mood or anxiety exacerbation
• Acne or oily skin
• Decreased libido
• Hyperglycemia in patients with pre‑existing diabetes

Serious

• Deep‑vein thrombosis or pulmonary embolism – risk increases with prolonged immobilization, smoking, or concurrent estrogen therapy.
• Severe allergic reaction (anaphylaxis) – characterized by rash, swelling, bronchospasm.
• Liver enzyme elevation – monitor in patients with hepatitis or chronic liver disease.

Drug–Drug Interactions

• Enzyme inducers (e.g., rifampicin, carbamazepine) may lower medroxyprogesterone plasma levels, reducing efficacy.
• CYP3A4 inhibitors (e.g., ketoconazole, erythromycin) can increase exposure, potentially heightening side‑effect risk.
• Anticoagulants – progestins may enhance the anticoagulant effect of warfarin; INR monitoring is recommended.
• Antiepileptic drugs – may attenuate hormonal control of seizures; dose adjustments may be necessary under specialist guidance.

Patients should disclose all prescription, over‑the‑counter, and herbal products before initiating Cycrin to allow comprehensive interaction screening.

Practical Use: Dosing, Missed Dose, Overdose

• Standard dosing for contraception: 5 mg of medroxyprogesterone acetate taken once daily at the same time each day.
• Therapeutic dosing for menstrual regulation or endometrial hyperplasia: 10 mg–15 mg once daily, as directed by the treating physician, typically for a 10‑day course each month.
• Missed dose – If a dose is forgotten within 12 hours, take it as soon as remembered. If more than 12 hours have elapsed, skip the missed dose and continue with the regular schedule; do not double‑dose.
• Overdose – Signs may include severe nausea, vomiting, or dizziness. Immediate medical attention is advised; supportive care is the primary treatment.
• Food and alcohol – Medroxyprogesterone can be taken with or without food. Excessive alcohol may increase the risk of liver enzyme elevation and should be avoided.
• Comorbidities – In patients with hepatic impairment, a reduced dose (e.g., 5 mg daily) is recommended, and liver function should be monitored regularly.

Patients are encouraged to keep a medication diary and discuss any adverse symptoms with their healthcare provider promptly.
