Salbutamol , also known as albuterol and marketed as Ventolin among other brand names,  is a medication that opens up the medium and large airways in the lungs.
Common side effects include shakiness, headache, fast heart rate , dizziness, and feeling anxious. Salbutamol was patented in in Britain and became commercially available in the UK in Salbutamol is typically used to treat bronchospasm due to any cause—allergic asthma or exercise-induced , as well as chronic obstructive pulmonary disease.
Intravenous salbutamol can be used as a tocolytic to relax the uterine smooth muscle to delay premature labor. While preferred over agents such as atosiban and ritodrine , its role has largely been replaced by the calcium channel blocker nifedipine , which is more effective and better tolerated. Salbutamol has been used to treat acute hyperkalemia , as it stimulates potassium flow into cells, thus lowering the potassium in the blood. The most common side effects are fine tremor , anxiety , headache , muscle cramps , dry mouth , and palpitation.
High doses or prolonged use may cause hypokalemia , which is of concern especially in patients with renal failure and those on certain diuretics and xanthine derivatives. Activation of these receptors causes adenylyl cyclase to convert ATP to cAMP , beginning the signalling cascade that ends with the inhibition of myosin phosphorylation and lowering the intracellular concentration of calcium ions myosin phosphorylation and calcium ions are necessary for muscle contractions.
The increase in cAMP also inhibits inflammatory cells in the airway, such as basophils , eosinophils , and most especially mast cells , from releasing inflammatory mediators and cytokines.
Salbutamol is either filtered out by the kidneys directly or is first metabolized into 4'-O-sulphate, which is excreted in the urine. Salbutamol is sold as a racemic mixture. Salbutamol was discovered in by a team led by David Jack at the Allen and Hanburys laboratory a subsidiary of Glaxo in Ware, Hertfordshire , England, and was launched as Ventolin in The Munich Olympics were the first Olympics where anti-doping measures were deployed, and at that time beta-2 agonists were considered to be stimulants with high risk of abuse for doping.
Inhaled salbutamol was banned from those games, but by was permitted although oral beta-2 agonists were not. After a steep rise in the number of athletes taking beta-2 agonists for asthma in the s, Olympic athletes were required to provide proof that they had asthma in order be allowed to use inhaled beta-2 agonists.
The drug is usually manufactured and distributed as the sulphate salt salbutamol sulphate. As of [update] there was no evidence that an increase in physical performance occurs after inhaling salbutamol, but various reports for benefit when delivered orally or intravenously.
The window of detection for urine testing is on the order of just 24 hours, given the relatively short elimination half-life of the drug,    estimated at between 5 and 6 hours following oral administration of 4 mg. Salbutamol has been studied in subtypes of congenital myasthenic syndrome associated with mutations in Dok It has also been tested in a trial aimed at treatment of spinal muscular atrophy ; it is speculated to modulate the alternative splicing of the SMN2 gene, increasing the amount of the SMN protein whose deficiency is regarded as a cause of the disease.
Salbutamol's low toxicity makes it safe for other animals and thus is the medication of choice for treating acute airway obstruction in most species. Toxic effects require an extremely high dose, and most overdoses are due to dogs chewing on and puncturing an inhaler or nebulizer vial.
