1. Question
What is an appropriate therapeutic alternative for Uniflu?
CorrectAnswer & Explanation:
The Answer is B
Explanation:
Uniflu contains paracetamol (non-opioid analgesic), codeine (opioid analgesic), caffeine, diphenydramine (antihistamine), phenylephrine (nasaldecongestant) and ascorbic acid. Day Nurse is the closest equivalent to Uniflu, as it contains paracetamol, phenylpropanolamine (nasal decongestant) and dextromethorphan (antitussive). Actifed contains triprolidine (antihistamine) and pseudoephedrine (nasal decongestant). Phenergan and Xyzal contain the antihistamines promethazine and levocetirizine respectively, whereas Ventolin contains salbutamol, which is a bronchodilator (selective beta2–adrenoceptor agonist).
