Composition

Salbutamol (4 Mg)

AVIHIST 4 MG TABLET 25 is used to manage breathing conditions such as asthma and chronic obstructive pulmonary disease (COPD). It belongs to a group of medicines called bronchodilators (beta-2 agonists), which relax the muscles around the airways to make breathing easier.

It helps relieve symptoms such as breathlessness, wheezing, chest tightness, and coughing. It is taken by mouth as prescribed.

Avoiding known triggers, such as smoke and allergens, supports easier breathing alongside this medicine.

Before starting, tell your doctor about any existing conditions or other medicines you take. Report any side effects to your doctor.

AVIHIST 4 MG TABLET 25 is used to manage asthma and COPD and to relieve and prevent bronchospasm. It eases wheezing, breathlessness, and chest tightness, helps prevent night-time and exercise-related symptoms, and supports easier breathing.

Primary Uses of AVIHIST 4 MG TABLET 25 are:

• Asthma and COPD: Helps relax the airways and ease wheezing, breathlessness, and chest tightness.

• Bronchospasm: Helps relieve and prevent sudden tightening of the airways, including with exercise.

Common side effects of AVIHIST 4 MG TABLET 25 are:

• Neurological: Headache, dizziness, nervousness, and shakiness.

• Cardiovascular: Fast heart rate (tachycardia).

Management Of Side Effects:

Most side effects are temporary and generally harmless, which resolve on discontinuing the use of AVIHIST 4 MG TABLET 25. However, if you experience any serious side effects or worsening of any of the symptoms, please consult your doctor.

Nausea: Taking this medicine with food can help reduce stomach discomfort.
Nervousness: You may find it helpful to take AVIHIST 4 MG TABLET 25 earlier in the day rather than close to bedtime.

AVIHIST 4 MG TABLET 25 contains Salbutamol (4 mg), which works on your body as follows:

Adenylyl cyclase activation: When salbutamol binds to beta-2 receptors, it activates an enzyme called adenylyl cyclase, which converts Adenosine Triphosphate (ATP) to cyclic adenosine monophosphate (cAMP).
Smooth muscle relaxation: The increased levels of cAMP in your lungs cause the smooth muscles surrounding your airways to relax.
Bronchodilation: This relaxation widens your airways (bronchi and bronchioles), allowing more air to flow in and out of your lungs and making breathing easier.

Caution is advised while taking AVIHIST 4 MG TABLET 25 if you are pregnant.
