About EphedrineAlpha/Beta Adrenergic Agonist , Sympathomimetic amine, Stimulant, vasopressor(parenteral), bronchodilator.Mechanism of Action of EphedrineEphedrine is a mixed acting sympathomimetic drug which mainly acting indirectly but also has some direct action on alpha and beta adrenergic receptors. It causes release of nor-epinephrine from it`s storage sites and stimulates alpha and beta adrenergic receptors. It relaxes bronchial smooth muscle by stimulating beta-2 adrenergic receptors and thus causes increased vital capacity, relief of mild bronchospasm, improved air exchange and decreased residual volume. Ephedrine produces cardiac stimulation with increased systolic and diastolic pressure when nor-epinephrine stores aren`t depleted. It produces positive inotropic effects with low doses through action on beta-1 receptors in heart. It causes vasodilatation through beta-2 receptors and vasoconstriction through alpha adrenergic receptors. Presser effects results from vasoconstriction, cardiac stimulation, and increased cardiac output. It produces nasal decongestant action by stimulating alpha receptors in blood vessels of nasal mucosa and causing vasoconstriction and nasal decongestion.Pharmacokinets of EphedrineAbsorption: Well absorbed after Oral, S.C., or I.M. administration.
Distribution: Widely distributed throughout the body

Protect from light.Effects of Missed Dosage of EphedrineTake the missed dose as soon as noticed and if it is the time for next dose then skip the missed dose. Continue the regular schedule. Do not double the dose.
Effects of Overdose of EphedrineProvide supportive treatment and symptomatic measures. If patient is conscious induce emesis and reduce absorption by administration of activated charcoal. Perform gastric lavage if required. Maintain airway and blood pressure and closely monitor vital signs. Do not administer vasopressors. Beta blockers such as propranolol are used to treat arrhythmias. Use cardio selective beta blockers in asthmatic patients. Treat hypertension with Phentolamine, Seizures with paraldehyde or Diazepam, Pyrexia with seizures.
Theophylline
About TheophyllineBronchodilator, a methylxanthine derivative, Anti asthma, in COPD.Mechanism of Action of TheophyllineIt inhibit phosphodiesterase enzyme which degrades cyclic nucleotides intracellularly and it results the cyclic AMP accumulation in the cell. This cause bronchodialatation, cardiac stimulation and vasodilatation. This drug release calcium from sarcoplasmic reticulam, especially in cardiac muscles and results increased cardiac muscle contraction. This drug also blocks adenosine receptors (adenosine acts as a local mediator in CNS & CVS and other organs- which contracts smooth muscles, especially in bronchi, blood vessels etc). This results bronchodialatation and vasodialatation.Pharmacokinets of TheophyllineAbsorption- Well absorbed after oral administration. Rapidly and well absorbed after intravenous administration.
