Are Tri-Sprintec and Norgestimate the Same? A Guide to the Difference

4 min read

Approximately 14% of contraceptive users in the US use the birth control pill, which may lead to confusion about product names versus ingredients. For those wondering, "are tri sprintec and norgestimate the same?", the short answer is no, one is an active ingredient found in the other. This guide clarifies the important pharmacological distinction.

Quick Summary

Norgestimate is a synthetic progestin hormone, while Tri-Sprintec is a specific triphasic brand of combined oral contraceptive that contains norgestimate and ethinyl estradiol as its active ingredients.

Key Points

  • Different Concepts: Norgestimate is a synthetic hormone (an active ingredient), whereas Tri-Sprintec is a specific brand of a combined oral contraceptive pill.

  • Component of Tri-Sprintec: Tri-Sprintec's active ingredients are norgestimate and ethinyl estradiol, which work together to prevent pregnancy.

  • Triphasic Nature: Tri-Sprintec is a triphasic pill, meaning the dose of norgestimate changes at three points during the monthly cycle.

  • Progestin Class: Norgestimate is classified as a synthetic progestin and is not a complete medication on its own for contraceptive purposes.

  • Broader Use: Norgestimate is a common ingredient found in many other birth control pill brands, not just Tri-Sprintec.

  • Understanding Mechanism: Grasping the difference helps in understanding the medication's mechanism, managing potential side effects, and differentiating between various birth control options.

The Fundamental Difference: Ingredient vs. Product

At its core, the primary distinction between Tri-Sprintec and norgestimate lies in their classification. Norgestimate is a progestin, which is a synthetic form of the hormone progesterone. It is a single component used in medication. Tri-Sprintec, on the other hand, is the brand name for a complete medication—specifically, a type of combined oral contraceptive (COC) pill. This medication includes norgestimate as one of its two active hormonal ingredients, along with the estrogen ethinyl estradiol. Therefore, one is an ingredient, and the other is a finished product that uses that ingredient.

What is Norgestimate?

Norgestimate is a synthetic female hormone belonging to the class of progestins. In the context of birth control, it acts to prevent pregnancy mainly by inhibiting ovulation, or the release of an egg from the ovary. It is not sold as a stand-alone medication for contraception and is always combined with an estrogen for this purpose. The body processes norgestimate into its primary active metabolite, norelgestromin, which carries out the main biological effects. A few important points about norgestimate include:

  • It is a third-generation progestin, first introduced in 1986.
  • It has very low androgenic activity compared to some other progestins, which can mean fewer androgen-related side effects, such as acne.
  • It is not exclusive to Tri-Sprintec and is present in numerous other birth control pills.

What is Tri-Sprintec?

Tri-Sprintec is a brand of prescription birth control pill that is classified as a triphasic combined oral contraceptive. The term "triphasic" refers to the fact that it delivers three different doses of hormones at three specific intervals during the 21-day active pill cycle. Each package contains 28 tablets, which includes 21 active tablets and seven inactive (placebo) tablets. The different colored active pills correspond to the different hormone dosages. This varying dosage is designed to mimic the natural hormonal fluctuations of a woman's menstrual cycle more closely than monophasic pills, which contain the same dosage in all active tablets. Tri-Sprintec is also FDA-approved for treating moderate acne in females aged 15 and older who desire contraception.

Comparison: Tri-Sprintec vs. Norgestimate

To further clarify the difference, let's look at a side-by-side comparison.

Feature Norgestimate Tri-Sprintec
Classification A synthetic progestin hormone A brand-name, combined oral contraceptive (COC)
Formulation An active pharmaceutical ingredient (API) A finished pharmaceutical product (pill)
Contents Single hormonal component Contains norgestimate, ethinyl estradiol, and inactive ingredients
Dosage The dose varies within the Tri-Sprintec product Triphasic; contains three different doses of norgestimate over the 21 active days
Purpose Part of a larger mechanism to inhibit ovulation and alter cervical mucus To prevent pregnancy and treat moderate acne
Availability Only available within a combination medication Available as a prescription medication

Why the Distinction is Crucial

Understanding the relationship between Tri-Sprintec and norgestimate is important for several reasons:

  • Understanding the mechanism: It helps patients grasp how their birth control works. The norgestimate is the progestin doing the heavy lifting in preventing ovulation, supported by the estrogen ethinyl estradiol.
  • Managing side effects: Norgestimate's low androgenic profile is a key feature of Tri-Sprintec. Patients experiencing androgen-related side effects on other medications might find Tri-Sprintec to be a suitable alternative.
  • Explaining alternatives: Patients might be prescribed a different brand, like Tri-Lo-Sprintec, which contains the same active ingredients but at a lower estrogen dose, or a monophasic pill like Sprintec, which has a steady dose of hormones. Knowing the roles of norgestimate and ethinyl estradiol can help patients understand why their prescription was changed.

Other Norgestimate-Containing Medications

Norgestimate is not exclusive to the Sprintec family of birth control pills. It is a common component in a variety of other branded medications. This demonstrates that while Tri-Sprintec is a specific product, norgestimate is a widely used ingredient. Examples of other oral contraceptives containing norgestimate and ethinyl estradiol include:

  • Estarylla
  • Tri-Mili
  • Tri-Linyah
  • Previfem
  • Tri-Previfem

Conclusion

In summary, the question of whether are Tri-Sprintec and norgestimate the same is an important one that highlights the difference between a medication's active ingredient and the final drug product. Norgestimate is a synthetic progestin hormone, a specific component of combined hormonal contraceptives. Tri-Sprintec is a brand of triphasic birth control pill that contains norgestimate, along with ethinyl estradiol, to prevent pregnancy and treat moderate acne. Being aware of this distinction is essential for understanding how hormonal birth control works, evaluating different formulations, and making informed decisions about contraception with a healthcare provider. Patients should always consult with a doctor to determine the most appropriate option for their specific health needs.

Frequently Asked Questions

The primary difference is that norgestimate is a synthetic progestin hormone, an active ingredient, while Tri-Sprintec is a specific brand of birth control pill that contains norgestimate along with ethinyl estradiol as its active components.

No, norgestimate is not sold as a standalone medication for contraception. For birth control, it is always combined with an estrogen, such as ethinyl estradiol, in a finished product like Tri-Sprintec.

In addition to norgestimate (a progestin), Tri-Sprintec also contains ethinyl estradiol, a synthetic form of estrogen.

It is called 'triphasic' because it has three phases of active pills within the 21-day cycle, each containing a different, specific dose of the progestin norgestimate. This mimics the body's natural hormonal fluctuations more closely than a monophasic pill.

No, many different oral contraceptives contain norgestimate, and they can differ in their dosing structure (e.g., monophasic vs. triphasic) or hormone levels (e.g., higher vs. lower dose), like Tri-Lo-Sprintec versus Tri-Sprintec.

Yes, some combined oral contraceptives containing norgestimate and ethinyl estradiol, including Tri-Sprintec, are FDA-approved for treating moderate acne in certain patients.

The different colors of the active pills in a Tri-Sprintec pack correspond to the different hormone dosage phases during the first three weeks of the cycle. The fourth week consists of inactive (placebo) tablets.

After oral ingestion, norgestimate is metabolized to its active forms, primarily norelgestromin. These progestin metabolites inhibit ovulation, thicken cervical mucus to block sperm, and alter the uterine lining to prevent implantation.
