Natural Micronised Progesterone: Soft-Gel vs SR Tablet vs Injection

Natural micronised progesterone is available in three presentations that are not interchangeable: soft-gelatin capsules, sustained-release tablets and injection. The route is a clinical decision, not a packaging preference, and a distributor who understands why will hold price where others discount. Halefem carries all three as MUGEST, alongside dydrogesterone as DYROCHEM.

Why progesterone is difficult to formulate

Progesterone is poorly and erratically absorbed when given as a plain compressed tablet. It is lipophilic, and it undergoes extensive first-pass metabolism in the liver. Swallow it in a conventional tablet and a large and unpredictable share never reaches circulation as progesterone.

Micronisation — reducing particle size — increases the surface area available for absorption and is what makes oral progesterone viable at all. But micronisation alone is not enough. How the micronised drug is delivered decides the outcome, and that is why the same molecule exists in three quite different products.

The three presentations

Soft-gelatin capsules

The micronised progesterone is suspended in an oil base inside a soft-gel shell. The lipid vehicle improves absorption of a lipophilic drug substantially, which is why the soft-gel became the standard oral form.

Used orally and, in a great deal of Indian practice, vaginally. The vaginal route matters clinically: it largely bypasses first-pass metabolism and produces high local uterine concentrations, which is why it is common in luteal phase support during IVF cycles.

The distributor point: a soft-gel cannot be substituted at the counter with a cheaper compressed tablet of the same nominal strength. They are not the same product. Doctors who prescribe soft-gels know this, and it is the most defensible position in your whole range.

Sustained-release tablets

An SR formulation releases the drug over a longer period, smoothing the peaks and troughs of immediate-release dosing. Where a clinician wants steadier levels with oral convenience, this is the form.

SR is a genuine formulation, not a marketing label — the release profile is engineered. A distributor should be able to say so plainly when a chemist suggests an alternative.

Injection

Intramuscular progesterone in oil bypasses the absorption question entirely and delivers reliable, high serum levels. It is used where certainty matters most — some IVF protocols, threatened miscarriage — and where oral or vaginal routes are unsuitable.

Injections carry handling obligations: they are Schedule C and C(1) products, so you need a Form 21B licence to hold them, and they ship with the syringe. That licensing barrier is also commercial protection — fewer distributors in your district can legally supply them.

Dydrogesterone is a different question

Dydrogesterone (DYROCHEM) is a retroprogesterone, orally active and structurally distinct from natural progesterone. It is widely used for luteal support and in threatened miscarriage protocols, and it is prescribed by brand more often than most molecules in a gynae range.

It is not a substitute for micronised progesterone and should not be positioned as one. Clinicians choose between them for reasons of route, tolerability and protocol. Carrying both means you have an answer whichever way the prescription goes — which is the entire argument for a gynae-only range.

Packing: this is where margin is won or lost

Soft-gelatin capsules contain an oil fill and are moisture-sensitive. They belong in Alu-Alu, not PVC. A soft-gel that has softened or leaked on a chemist’s shelf through an Indian summer is a complaint, a return, and a doctor who quietly stops writing your brand.

Injections need appropriate handling through the chain and ship with the syringe. Halefem matches packing to the molecule across the range for exactly this reason — it is not a premium feature, it is the minimum for a product that has to survive distribution and still work.

What a gynaecologist will ask you

• Which strengths do you carry, and in which forms? A partner who can supply 100 mg and 200 mg soft-gels plus the injection covers most protocols.
• Is the soft-gel suitable for vaginal use? A significant share of Indian luteal support prescribing is vaginal.
• What is your supply consistency? Nobody starts a patient on a luteal protocol with a brand that may vanish in month two.

That last one is the real test. Progesterone is prescribed at moments of clinical anxiety — a threatened miscarriage, an IVF cycle a couple has saved for. A stockout here does more damage to a distributor’s reputation than in any other part of a gynae range.

Frequently asked questions

What is the difference between micronised progesterone soft-gel, SR tablet and injection?

The soft-gel suspends micronised progesterone in an oil base to improve absorption and can be used orally or vaginally. The SR tablet releases the drug over a longer period for steadier oral levels. The injection bypasses absorption entirely and gives reliable serum levels. They are chosen on clinical grounds and are not interchangeable.

Why can’t progesterone be given as an ordinary tablet?

Progesterone is lipophilic and heavily metabolised on first pass through the liver. In a plain compressed tablet, absorption is poor and unpredictable. Micronisation plus an appropriate delivery form is what makes oral progesterone workable.

Is micronised progesterone the same as dydrogesterone?

No. Dydrogesterone is a retroprogesterone, structurally distinct and orally active, used widely for luteal support. It is a different clinical choice rather than a substitute, which is why a gynae range should carry both.

Do I need a special licence to distribute progesterone injection in India?

Yes. Injectables fall under Schedule C and C(1), so you need a Form 21B wholesale licence in addition to Form 20B. Fewer distributors hold it, which reduces competition in the segment.

Why must progesterone soft-gels be packed in Alu-Alu?

The capsule contains an oil fill and is moisture-sensitive. PVC offers weaker moisture protection, and a softened or leaking capsule on a chemist’s shelf becomes a return and a lost prescriber.
