Diprophylline is a medication that belongs to the class of xanthine derivatives, which are used primarily to treat respiratory conditions such as asthma, chronic obstructive pulmonary disease (COPD), and bronchitis. It works by relaxing the smooth muscles in the airways and improving the flow of air into and out of the lungs. Diprophylline is typically taken orally in the form of tablets or capsules, and its effects can last for several hours. However, it can cause side effects such as nausea, vomiting, headache, dizziness, and rapid heart rate, and can interact with other medications such as antibiotics, antifungals, and caffeine. Therefore, it should be taken only under the supervision of a healthcare provider and at the prescribed dosage.
