A drug may be classified by the chemical type of the active ingredient or by the way it is used to treat a particular condition. Each drug can be classified into one or more drug classes.

Rifamycin derivatives are antibiotics that work by binding to and inhibiting the mycobacterial DNA dependent RNA polymerase. These antibiotics are bacteriocidal and therefore extremely effective antituberculosis agents, but resistance can develop rapidly if used as a single agent. They easily penetrate into cells, body fluids and cerebrospinal fluid so can be used against organisms in the extracellular component and those that may be present in cells such as macrophages. Rifamycin antibiotics should be used throughout the course of tuberculosis treatment, which can be between nine months to a year.

Recombinant human erythropoietins, act like endogenous erythropoietin to stimulate erythropoiesis, the process of red blood cell production. Endogenous erythropoietin is a hormone that is secreted by particular cells in the kidneys in response to reduced levels of oxygen reaching the tissues in the kidneys.

Recombinant human erythropoietins are given to patients with kidney failure to treat anemia.

Renin inhibitors block the activity of renin and cause vasodilatation. Renin is an enzyme that converts angiotensinogen to angiotensin I, which is then converted to angiotensin II by angiotensin converting enzyme. Angiotensin II is a potent vasoconstrictor that causes the blood pressure to rise.

Renin inhibitors are used to treat hypertension.

Respiratory agents are drugs or a combination of drugs used to prevent, relieve or treat respiratory diseases. They can be taken as pills or liquid, for the drugs to work systemically. Or they can be available as inhalers or other forms or inhalation devices, where the medicine is delivered directly into the lungs.
