Apart from serving as an alleviator for several respiratory issues, the Aminophylline cream is used for reducing fat around the thigh region as well. 

Aminophylline to Theophylline conversion

Before we talk about the conversion, it is important to mention here that Aminophylline is a compound of another bronchodilator known as theophylline. Ethylenediamine is found in this compound as well, the ratio between Aminophylline and Ethylenediamine is 2:1. Coming towards the main subject of this section, to calculate the dose of theophylline, multiply the Aminophylline dose by a factor of 0.8. The rationale behind this multiplication is that Aminophylline contains 80% theophylline. The key assumption made here is that the oral product is completely absorbed.

Mechanism of Action of Aminophylline

As mentioned earlier, Aminophylline is a complex of two compounds i.e. theophylline and ethylenediamine. Of these, it is theophylline that contributes most to the effect produced by the Aminophylline drug. Since theophylline can relax smooth muscles, the medication is super effective in relieving the bronchial spasm. The group of muscles targeted in this case is smooth muscles of the bronchial airways. 

Aminophylline Manufacturing Process

Aminophylline is manufactured by adding a strong aqueous solution of ethylenediamine to solid theophylline that is agitated in an appropriate vessel. Here, two moles of theophylline react with one mole of ethylenediamine to produce Aminophylline. It is worth mentioning here that there are some issues annexed with this method of preparation of Aminophylline at the commercial level e.g. formation of product lumps. 

Aminophylline Uses

Some of the conditions for which this medication can be used include acute exacerbation of chronic bronchitis (AECB), asthma, bronchial asthma, bronchospasm, chronic bronchitis, emphysema, and certain other conditions that can lead to respiratory constrictions.
