The discovery made waves, but Wurtman warned at the time that “people should not self-medicate with melatonin,” fearing possible mood-altering side effects. Because the hormone is found naturally in some foods, US law allows it to be sold as a dietary supplement instead of as a drug. Manufacturers don’t have to prove melatonin is safe or effective, and since labels tend to describe it vaguely as a “drug-free sleep aid” or a “clinically studied ingredient,” many consumers don’t realize they’re taking a hormone. “We have 26 people who work on dietary supplements directly,” says Food and Drug Administration spokeswoman Lyndsay Meyer, who notes that the agency had less than $5 million to regulate the $41 billion industry last year.
Some studies indicate that large doses of synthetic melatonin can increase the body’s levels of prolactin, a hormone that helps regulate the menstrual cycle, triggers milk production in new mothers, and is associated with altered sperm count in men. Other research suggests melatonin may affect sex drive. Meanwhile, scientists don’t even agree on the proper dose to use for insomnia. Wurtman recommends between 0.3 mg and 1 mg, warning that more might lead to desensitization and daytime grogginess. But 1 mg is the smallest dose available in most stores, and people often opt for 5-mg or 10-mg pills instead—potentially elevating their blood melatonin levels to 50 or even 100 times normal levels. A study published in the Journal of Clinical Sleep Medicine found that for more than 71 percent of over-the-counter melatonin samples tested, manufacturers didn’t accurately label the doses—one product contained nearly five times more of the hormone than listed.
At high doses, Wurtman argues, melatonin soon becomes ineffective for sleeplessness; receptors in the brain can stop responding to it. (Wurtman receives royalties from a company that sells melatonin capsules containing doses of less than 1 mg.) In parts of Europe, where you’d need a doctor’s prescription to buy melatonin, experts also recommend 1 mg a night. I spoke to several US scientists who agree many American insomniacs are taking more of the hormone than necessary. “Most people, not understanding the science, might pick the higher dose,” says Craig Hopp, a program director at the National Institutes of Health. “It’s somewhat human nature, at least in American culture, that more must be better.” While there’s no damning evidence to suggest higher doses are harmful, he says, if you’re taking melatonin for weeks or years, “it could be that lower doses might be preferential.” Still, without documented adverse effects, many doctors don’t see a problem recommending melatonin at higher doses, and for long-term use. Even Wurtman pops a melatonin pill each night—though he keeps his intake to less than 1 mg, of course. Turning off your screens and giving yourself more time to unwind in the dark can stimulate natural melatonin production. That’s not always easy for those of us glued to our email or Netflix, but I’m giving it a shot. After half a decade of taking melatonin every night, I weaned myself off the hormone completely about a month ago. Dear Reader, This feels like the most important fundraising drive since I've been CEO of Mother Jones , with staggeringly high stakes and so much uncertainty. In "News Is Just Like Waste Management," I try to unpack the reality we all face and how we can rise to the challenge. If you're able to, this is a critical moment to support Mother Jones ’ nonprofit journalism: We need to raise $400,000 to help cover the vital reporting projects we have planned, and right now is no time to pull back.

It is estimated that more than 40% of new chemical entities (NCEs) coming out of the current drug discovery process have poor biopharmaceutical properties, such as low aqueous solubility and/or permeability. These suboptimal properties pose significant challenges for the oral absorption of the compounds and for the development of orally bioavailable dosage forms. Development of soft gelatin capsule (softgel) dosage form is of growing interest for the oral delivery of poorly water soluble compounds (BCS class II or class IV). The softgel dosage form offers several advantages over other oral dosage forms, such as delivering a liquid matrix designed to solubilize and improve the oral bioavailability of a poorly soluble compound as a unit dose solid dosage form, delivering low and ultra-low doses of a compound, delivering a low melting compound, and minimizing potential generation of dust during manufacturing and thereby improving the safety of production personnel.
However, due to the very dynamic nature of the softgel dosage form, its development and stability during its shelf-life are fraught with several challenges. The goal of the current review is to provide an in-depth discussion on the softgel dosage form to formulation scientists who are considering developing softgels for therapeutic compounds. Soft Gelatin Capsules (Softgels) ABOUT AUTHORS: Abhishek Raj Deputy Manager (R&D) Quest Pharmaceuticals Pvt. Introduction A softgel or soft gelatin capsule is a solid capsule (outer shell) surrounding a liquid or semi-solid center (inner fill).
An active ingredient can be incorporated into the outer shell, the inner fill, or both. They are oral dosage form for medicine similar to capsules. Softgel shells are a combination of gelatin, water, opacifier and a plasticizer such as glycerin and/or sorbitol(s). PharmaTutor (Print-ISSN: 2394 - 6679; e-ISSN: 2347 - 7881) Volume 3, Issue 10.
