Metrogel User Reviews

What is metronidazole ? well scientifically it is a white to pale yellow crystalline powder. Metronidazole is a member of the imidazole class of anti-bacterial agents and is classified as an antiprotozoal and anti-bacterial agent.

When taken orally, metronidazole is known as flagyl. Flagyl is used for a wide variety of infections including those in the adbomen, bones, joints, nervous system, respiratory tract, skin, as well as vaginal and intestinal infections.

A bit of history

Curatek Pharmaceuticals developed and submitted the New Drug Application for Metrogel in 1988. Since its introduction by Curatek, MetroGel has become the most widely prescribed therapy in the United States for rosacea. In 1993 Curatek Pharmaceuticals sold metrogel to Galderma Laboratories. Galderma has since introduced other variants of Metrogel, namely MetroLotion and MetroCream. Galderma is also an interesting company for rosacea sufferers because they have purchased Collagenex, who are developing a product we know as sansrosa.

Curatek, continued to market MetroGel-Vaginal (metronidazole vaginal gel, 0.75 percent) for bacterial vaginosis. MetroGel-Vaginal was introduced in the U.S. in 1992.

How does metrogel work ? well amazingly after all these products have been marketed and many studies done, the mechanisms by which metronidazole acts in reducing the inflammatory lesions of rosacea are in the main unknown.

Dermik markets a 1%, once a day formulation of metronidzole called Noritate.

Metrogel was responsible for generating sales of about $75 million in 2004.

The patent on the branded product by Galderma expired on June 6, 2006. Fougera is poised to make generic metrogel available, having had tentative approval to produce a generic metrogel.

In July of 2005 Galderma announced that 1 percent metrogel had gained FDA approval. The vehicle is a water-based formulation and contains no alcohol.  The formulation was `enhanced with HSA-3′. HSA-3 is described as a combination of ingredients including betadex, niacinamide (vitamin B3), and propylene glycol.”

Metrogel Ingredients

METROGEL (metronidazole gel), 1% is an aqueous gel; each gram contains 10 mg of metronidazole in a base of betadex, edetate disodium, hydroxyethyl cellulose, methylparaben, niacinamide, phenoxyethanol, propylene glycol, propylparaben and purified water.

So Why all the “Metro” products ?

Despite quite a lot of activity in the marketing and development of the metronidazole treatments (lotion, cream, gel, generic equivalents, nortitate 1%, metrogel 1%, once per day, twice per day etc) this particular research paper Metronidazole in the treatment of rosacea: do formulation, dosing, and concentration matter? suggests that the different formulations and treatment frequency make little difference to the treatment outcome.

Thus if you are already using one formulation of metronidazole, changing to another gel/cream vehicle doesn’t appear to be able to offer any additional benefits.

Does Metrogel help with the Redness?

Officially, Metrogel is only indicated for the papules and pustules of rosacea – this is what it was tested against. Some users of Metrogel do find a reduction in redness as a result of the anti-inflammatory actions of metronidazole, but you should probably consider this a bonus rather than a given.

Also known as Metrosa and Rozex

There are some slight variations in the actual product name for metronidazole based products around the world. You may come across references to Metrosa and Rozex. These contain the same active ingredient as Metrogel, but the overall formulation may vary slightly. In general they will all offer the same potential benefit to rosacea suffers – that is, one formulation is most likely to offer the same benefit to the lumps and bumps of rosacea as another.
