Clarithromycin belongs to a clinical antibiotic, which is a macrolide antibiotic. It is clinically indicated for infections of gram-positive bacteria, such as upper respiratory tract infections and tracheitis and bronchitis. Clarithromycin Dispersible Tablets can be pressed into powder form because the texture is in a dispersible form, which is then suitable for children. The usual adult dose is 1 capsule of 250 p.c. twice a day. For some specific diseases there are also their own special uses, for example, sinusitis can be used in small doses, 1 time a day. Clarithromycin is mainly metabolized by the liver, so it is not usually used at the same time as other medications, such as antimycobacterials and antiallergic drugs. The reactions to clarithromycin are mainly gastrointestinal and are milder than those to erythromycin.
