The U.S. Food and Drug Administration (FDA) states its purpose in the following mission statement:
“The FDA is responsible for protecting the public health by assuring the safety, efficacy, and security of human and veterinary drugs, biological services, medical devices, our nation’s food supply, makeup, and services that emit radiation. The FDA is also responsible for advancing the public health by helping to speed innovations that make medicines and foods more effective, safer, and more reasonably priced; and helping the public obtain the accurate, science-based info they want to use medicines and foods to improve their health.”
In 2005 the FDA offered a public draft guidance document to the pharmaceutical sector on the creation of drugs to cure acne pimples vulgaris, or acne pimples. The draft guidance document contains the FDA’s current thinking on the creation of acne pimples drugs and the techniques that should be used.
Some of the guidance document info is summarized below. At the time of this writing the FDA document had not been finalized.
Varieties of acne pimples Lesions
The two key varieties of acne pimples lesions are classified as non inflammatory and inflammatory. Non-inflammatory acne pimples lesions are usually more commonly referred to as whiteheads and blackheads. Inflammatory acne pimples lesions encompass papules and pustules and are usually more deeply seated in the skin than the non inflammatory lesions.
Exactly how acne pimples Severity Is Rated
Currently there is no standardized technique for rating the severity of acne pimples outbreaks. Several techniques have been proposed, but each has its difficulties. A sample scale for rating acne pimples severity is summarized below, from least to most severe:
0 crystal clear epidermis with no inflammatory or non inflammatory lesions
1 Almost crystal clear; rare non inflammatory lesions with no more than one tiny inflammatory lesion
2 minimal severity; greater than Grade 1; some non inflammatory lesions with no more than a few inflammatory lesions (papules/pustules only, no nodular lesions)
3 medium severity; greater than Grade 2; up to numerous non inflammatory lesions and may have some inflammatory lesions, but no more than one tiny nodular lesion
four* severe; greater than Grade 3; up to numerous non inflammatory and inflammatory lesions, but no more than a few nodular lesions
(* worsening beyond Grade four is possible).
Acne Drug treatment Study Groups
Acne drug test groups should be big enough to be statistically substantial so that any claims of success and safety might be supported. Test clients are typically recruited during their most severe acne pimples skin breakouts.
Acne drug trials are recommended to be randomized, blinded, multicenter trials, and other specifications will also apply. A control or placebo group should be utilized.
Furthermore, those doing testing should aquire test populations that are representative of the age, race, gender, and geographic location of acne pimples clients in the United States.
Determining The success Of acne pimples Drug treatments
Acne severity is rated at the commencing and end of every test. Photographic evidence and/or lesion counts may also be taken. It is proposed to measure the success of acne pimples drugs as either a success or a failure, based on one of these two techniques of measuring success:
- Victory meaning a rating of crystal clear epidermis or almost crystal clear (severity rating 0 or 1) inside the test period; or
- Victory meaning an improvement of 2 severity grades inside the test period. Under this definition, a effective test subject would have a severity improvement from four to 2 inside the test period, as an example.
The Final Decision On completely new acne pimples Drugs
Several phases of testing are recommended for proposed acne pimples drugs. Studies must be created to account for effects such as test dropouts. Rigorous data examination must be performed in conformance with FDA regulations. Only acne pimples drug test data that has been validated and undergone high-quality assurance testing should be submitted to the FDA for approval.
Only via a rigorous and tightly-controlled testing and examination process, followed by FDA approval, might completely new acne pimples drugs be made readily available to the public.
