Susten SR 300mg Tablet 10'S

Introduction About SUSTEN SR 300MG TABLET

SUSTEN SR 300MG TABLET contains a medicine called progesterone which is a
steroid hormone that functions similar to the endogenous female sex hormones.

It is used in the management of female infertility and other progesterone
deficiency states such as abnormal uterine bleeding, menopausal disorders and
secondary amenorrhea in combination with oestrogen therapy. It supports the
early stages of pregnancy and reduces the risk of threatened abortions and
pre-term delivery in pregnant women.

Inform your doctor if you have any liver, heart or kidney problems, diabetes,
asthma, epilepsy, or depression. Do not take SUSTEN SR 300MG TABLET if you have
or previously had breast cancer, uterine cancer, unexplained vaginal bleeding,
or blood clots. Your doctor will instruct you to have periodic blood tests and
regular physical examination (breast and uterine examination) as a precaution.

SUSTEN SR 300MG TABLET may be prescribed by your doctor during early stages of
pregnancy to support the growth of fetus. However, consult your doctor before
taking it. SUSTEN SR 300MG TABLET is not recommended for use in breast-feeding
women and in children and adolescents (below 18 years of age).

Common side effects of taking SUSTEN SR 300MG TABLET are headache, hair loss,
pain in the breast, stomach or abdominal cramps, bloating, nausea, vomiting.
Consult your doctor if any of the side effect worsens.

Benefits of SUSTEN SR 300MG TABLET

Its sustained-release formulation allows progesterone to be released slowly over
several hours, helping maintain a more consistent hormone level through the day.

2. Supports Hormone Balance in Healthcare-Supervised Plans

Often included in hormone-support regimens where maintaining progesterone levels
is essential as guided by healthcare professionals.

3. Designed for Once-Daily Convenience

The sustained-release format may reduce the need for multiple doses per day,
making it convenient for routine use.

4. Uses Natural Micronised Progesterone

Contains micronised progesterone, which is a form commonly used to support
natural hormonal functions under medical supervision.

5. Useful in Various Progesterone-Support Protocols

Healthcare providers may include this tablet in different hormone-management or
supplement plans depending on individual requirements.

6. Helps Align with Body’s Natural Hormonal Rhythm

Its slow-release mech
fluctuations more smoothly compared to immediate-release o

7. Patient-Friendly Oral Tablet Format

Easy to take, swallow, and store making it a convenient o
supplementation.

How SUSTEN SR 300MG TABLET Works

1. Sustained-Release (SR) Technology Controls How the Tablet Dissolves

• The tablet is formulated with a special matrix that slowly breaks down after swallowing.
• This allows progesterone to be released gradually over several hours instead of all at once.
• As a result, the bloodstream receives progesterone in steady and controlled amounts, helping maintain stable hormone levels during the day.

2. Micronised Progesterone Improves Absor

• The progesterone particles are micronised (reduced in size).
• Smaller particles improve solubility and allow easier absor
• This ensures a more predictable and uniform uptake compared to non-micronised forms.

3. Hormonal Binding and Distribution in the Body

Once absorbed:

• Progesterone enters the bloodstream and binds to progesterone receptors present in various tissues.
• These receptors help the hormone interact with endometrial tissue, reproductive organs, brain, and other hormonal pathways, supporting normal physiological functions.
• This receptor interaction helps maintain the natural cyclical hormonal environment guided by the body.

4. Mimics the Body’s Natural Progesterone Pattern

• Because the tablet delivers progesterone slowly, it more closely resembles how the body naturally releases progesterone in phases.
• This reduces sharp hormonal fluctuations and supports a more consistent hormonal environment through the dosing interval.

5. Longer Duration of Action

• Due to sustained release, progesterone remains available in the bloodstream for a longer period.
• This helps extend the duration of hormonal availability compared to immediate-release formulations, which dissolve faster.

6. Stable Blood Levels Support Routine Hormonal Balance

• Controlled delivery leads to stable plasma concentrations, avoiding sudden peaks or drops.
• This steady profile is beneficial in healthcare-supervised hormonal regimens that rely on predictable progesterone levels.

7. Reduced Need for Frequent Dosing

• The extended-release format typically supports once-daily intake, depending on clinical guidance.
• This improves convenience and supports better adherence to hormone-support plans.

Drug - Drug interaction

1. Medicines That Affect Hormone Levels

Certain hormonal preparations may interact with progesterone:

• Other progesterone or estrogen-containing medications
• Hormonal support or reproductive health medicines
• Corticosteroids

These may influence overall hormone balance or modify progesterone activity.

2. Medicines Affecting Liver Enzymes

Progesterone is metabolized in the liver, so drugs that induce or inhibit liver
enzymes may affect its levels:

• Enzyme inducers (may reduce progesterone levels):

– Rifampicin

– Carbamazepine

– Phenytoin

– Phenobarbital

• Enzyme inhibitors (may increase progesterone exposure):

– Ketoconazole

– Itraconazole

– Erythromycin

– Clarithromycin

These interactions may require professional monitoring or adjustment.

3. Sedatives and CNS-Acting Medicines

Progesterone may have mild sedative effects in some individuals. Combining it
with other CNS depressants may enhance drowsiness:

• Sleep aids
• Anti-anxiety medicines
• Certain antihistamines
• Alcohol-containing formulations

Caution is advised when combining such products.

4. Medicines Used for Thyroid and Metabolic Conditions

Some studies suggest progesterone may influence thyroid-binding proteins or
metabolic pathways. Patients using thyroid medications, diabetes medicines,
or similar metabolic agents should confirm compatibility with their healthcare
provider.

5. Herbal and Dietary Interactions

Natural or herbal products may also influence hormone levels or liver
metabolism:

• St. John’s Wort
• High-dose supplements affecting hormonal pathways

These may reduce or alter progesterone’s expected exposure.

Drug - Food interaction

1. Effect of Food on Absor

• Taking progesterone tablets with food, particularly a high-fat meal, can increase the absor
• This may lead to higher-than-expected blood levels, as food slows gastric emptying and enhances uptake.
• Because sustained-release tablets rely on controlled release, irregular food habits can affect the release profile.

2.  Caffeine-Rich Foods and Beverages

• Caffeine does not directly interact with progesterone metabolism.
• However, it may worsen symptoms like nervousness or sleep disturbance in sensitive individuals.

More Information

Why Sustained-Release Formulations Are Preferred

• Sustained-release (SR) formulations are designed to release the active ingredient slowly and steadily over several hours.
• This controlled delivery helps maintain more stable hormone levels, reducing the sharp peaks and drops that may occur with immediate-release tablets.
• SR tablets also support better convenience, as they often require fewer doses in a day, which can improve routine consistency for individuals following hormone-support plans.
• Additionally, a gradual release mirrors the body’s natural rhythm more closely, offering a smoother hormonal exposure throughout the dosing interval.

Difference Between Natural and Synthetic Progesterone Forms

Natural micronised progesterone is structurally identical to the progesterone
produced by the human body. Because its molecular structure matches the body’s
own hormone, it interacts with progesterone receptors in a more physiologically
familiar way. Synthetic progesterone forms (progestins), on the other hand,
are chemically modified versions used in various hormonal preparations. These
may differ in how they bind to receptors, how long they stay in the body, and
the kinds of hormonal effects they produce.

Natural progesterone is often chosen in situations where a closer alignment with
the body’s own hormone profile is desired, while synthetic forms may be selected
for specific clinical goals depending on the healthcare provider’s judgment.
