What is the primary clinical indication and mechanism of Mucoregulators?

Mucoregulators modify mucus secretion rates and composition (e.g., Ambroxol, Bromhexine, Carbocisteine - ABC).

Additional Information: Certain clinical trials consider their therapeutic effect equivalent to placebo. Mnemonic: ABC = Ambroxol, Bromhexine, Carbocisteine.

Mucolytics chemically cleave disulfide bonds in mucoproteins to reduce mucus viscosity. The primary example is N-Acetylcysteine (NAC).

Additional Information: N-Acetylcysteine also serves as the specific antidote for Paracetamol (Acetaminophen) toxicity.

What dual therapeutic applications does N-Acetylcysteine (NAC) possess?

1) Mucolytic for thinning respiratory secretions

Which antitussive drug acts peripherally (PNS) on cough receptors?

Butamirate citrate (Sinecod®).

Additional Information: Indicated as a dry cough remedy by reducing peripheral sensory stimuli.

Which antitussives act centrally (CNS) on the medullary cough center?
