Many teenagers and some adults report getting some pimples, many of which they can treat with over-the-counter acne products. Fighting severe acne – especially cystic acne, which can lead to scarring – sometimes requires a potent prescription drug known as isotretinoin, a derivative of vitamin A. Pharmacies in the U.S. sell isotretinoin under the brand name Accutane, produced by drug manufacturer Hoffman-LaRoche. Cipla Ltd., a company based in India, also manufactures a medication in India and Greece that contains isotretinoin. Marketed under the brand name Isotroin, it is available in gel capsules. Generic Accutane Capsules (Isotroin), is an extremely powerful and potent acne-controlling medicine, is used to treat severe recalcitrant nodular acne which are resistant to therapy, particularly cystic acne and acne conglobata, especially when the lesions involve the trunk. Nodules are inflammatory lesions which have a diameter of 5 mm or greater.
