Aminophylline Health Dictionary

An alkaloid (see ALKALOIDS) structurally similar to CAFFEINE, and found in small amounts in tea. Its main use is for the relief of BRONCHOSPASM, where beta-2 adrenoceptor stimulants have failed. It is given intravenously in combination with the stabilising agent ethylenediamine (as aminophylline) for the treatment of severe ASTHMA or paroxysmal nocturnal DYSPNOEA. Formerly used in the treatment of left ventricular failure, it has been largely superseded by more e?ective DIURETICS. When indicated, aminophylline should be given by very slow intravenous injection; acute overdose may cause convulsions and cardiac ARRHYTHMIA.... theophylline

Action: Expectorant (used in bronchial, asthmatic and pulmonary affections), antispasmodic, febrifuge.

Key application: As bronchodilatory, expectorant. (Indian Herbal Pharmacopoeia.) The Ayurvedic Pharmacopoeia of India indicates its use in dyspnoea.

The chief quinazoline alkaloid vas- icine is reported in all parts of the plant, the highest being in inflorescence. It is a bitter bronchodilator, respiratory stimulant, hypotensive, cardiac depressant, uterotonic and aborti- facient. An aqueous solution of va- sicinone hydrochloride, when studied in mice and dogs, was found to potentiate the bronchodilatory activity of aminophylline, also that of isopre- naline. Vasicinone exhibited smooth- muscle-relaxant properties of airways.

Alkaloids present in the plant showed significant protection against allergin-induced bronchial obstruction in guinea pigs.

The leaves are found to activate the digestive enzyme trypsin.

An extract of the leaves showed significant antifungal activity against ringworm.

Adhatoda beddomei C.B. Clarke, found in Kerala, is considered to be more powerful and active than A. vasi- ca. Fresh leaf juice is used in haemoptysis and menorrhagia, also as an antiasthmatic.

Jacobinia tinctoria Henl. is equated with the red-flowered var. of Vaasaa.

Dosage: Leaf—10-20 ml juice. Dried leaves—10-20 g for deoction. Root—3-6 g powder. (API Vols. I, IV)... adhatoda vasica

A group of drugs that widen the bronchioles (small airways in the lungs) to increase air flow and improve breathing, especially in the treatment of asthma and chronic obstructive pulmonary disease (see pulmonary disease, chronic obstructive). There are 3 main types of bronchodilator: sympathomimetic drugs (such as salbutamol), anticholinergic drugs, and xanthine drugs (such as aminophylline). Sympathomimetic drugs are used primarily for the rapid relief of breathing difficulty. Anticholinergic and xanthine drugs are more often used for the long-term prevention of attacks of breathing difficulty. Drugs can be given by inhaler, in tablet form, or, in severe cases, by nebulizer or injection.

The main side effects of sympathomimetics are palpitations and trembling.

Anticholinergics may cause dry mouth, blurred vision, and, rarely, difficulty in passing urine.

Xanthines may cause headaches, nausea and palpitations.... bronchodilator drugs

Accumulation of fluid in the lungs, usually due to leftsided heart failure. It may also be due to chest infection, inhalation of irritant gases, or to any of the causes of generalized oedema. The main symptom is breathlessness, which is usually worse when lying flat and may disturb sleep. There may be a cough, producing frothy, sometimes pink, sputum. Breathing may sound bubbly or wheezy.

A diagnosis is made by a physical examination and by a chest X-ray. Treatment may include morphine, diuretic drugs, aminophylline, and oxygen therapy; artificial ventilation may also be given.... pulmonary oedema
