| Salbutamol tablets |
Salbutamol (Albuterol){Is Albuterol the same as salbutamol?} A highly selective β2 agonist; cardiac side effects are less prominent. Selectivity is further increased by inhaling the drug. Inhaled salbutamol delivered mostly from pressurized metered dose inhaler (pMDI) produces bronchodilatation within 5 min and the action lasts for 2–4 hours. It is, therefore, used to abort and terminate attacks of asthma, but is not suitable for round-the-clock prophylaxis. Muscle tremors are the dose related side effect. Palpitation, restlessness, nervousness, throat irritation and ankle edema can also occur. Hypokalaemia is a possible complication.
Salbutamol undergoes presystemic metabolism in the gut wall, oral bioavailability is 50%. Oral salbutamol acts for 4–6 hours, is longer acting and safer than isoprenaline, but not superior in bronchodilator efficacy. Because of more frequent side effects, oral β2 agonist therapy is reserved for patients who cannot correctly use inhalers or as alternative/adjuvant drugs in severe asthma.
