CIP isotretinoin

What is CIP isotretinoin?

CIP isotretinoin is a form of the drug isotretinoin that provides more consistent absorption than existing isotretinoin products. Isotretinoin is an important medication that is used to treat severe or persistent forms of acne and other skin conditions. CIP isotretinoin has recently been approved for use in the United States of America, but is not yet available in other countries (July 2012).

Why is constant absorption of isotretinoin important?

A major problem for existing isotretinoin products is patient compliance, as the active ingredient must be taken with a high-fat meal to ensure consistent absorption. Isotretinoin is often taken by teens. The eating habits of adolescents are often irregular compared to adults of working age. On May 25, 2012, the FDA approved CIP-isotretinoin (Absorica ™; CIPher Pharmaceuticals Canada), which provides more consistent absorption under food and fasting conditions compared to existing isotretinoin products that exhibit a reduction of 65% in absorption under fasting conditions. CIP isotretinoin can be taken with or without food.

CIP isotretinoin is very similar to isotretinoin (marketed under various brands by various manufacturers). However, it is not exactly the same as isotretinoin, due to the differences in how well the drug is absorbed; CIP isotretinoin is well absorbed with or without food, while the other isotretinoin products should be taken with food to achieve good absorption.

When is CIP-isotretinoin prescribed?

What is the usual dose and the course of treatment?

In most cases, the recommended dose of isotretinoin CIP is 0.5 mg to 1 mg per kg of body weight (approximately 0.23 mg to 0.45 mg per lb) each day, divided into two daily doses.

Research evidence for isotretinoin CIP

In a randomized double-blind In a study involving 925 patients with severe nodular acne, CIP-isotretinoin was as effective as isotretinoin in achieving a 90% reduction in nodular lesions over a period of 20 weeks.

From a security perspective, the first-line data was positive and did not show general statistical differences in the adverse event profile between the two products. The most frequent side effects observed were dry skin and dry lips. Also, initial statistics on psychiatric disorders, eye disorders, ear disorders, musculoskeletal, vascular disorders, cardiac disorders and gastrointestinal disorders, illustrate that there were no significant differences in the extent of adverse events between CIP-isotretinoin and the reference product.
