-OTC medications used to treat cough
● Opioid Antitussives
○ Codeine
○ Hydrocodone
● Nonopioid Antitussives
○ Dextromethorphan
○ Diphenhydramine
○ Benzonatate
● Expectorants
○ Guaifenesin
● Mucolytics
○ Hypertonic saline
○ Acetylcysteine
-Benzoyl Peroxide use and side effects
● first-line drug for mild to moderate acne is both an antibiotic and keratolytic. Improvement can be
seen within days of starting treatment. Benefits derive primarily from suppressing the growth of P.
acnes.
● It may produce drying and peeling of the skin. If signs of severe local irritation occur (e.g., burning,
blistering, scaling, swelling), the frequency of application should be reduced.
-Side effects of decongestants (sympathomimetics)
● Rebound congestion develops when topical agents are used more than a few days. With prolonged
use, as the effects of each application wear off, congestion becomes progressively worse
● Central nervous system (CNS) excitation is the most common adverse effect of the oral
sympathomimetics. Symptoms include restlessness, irritability, anxiety, and insomnia.
● By activating α1-adrenergic receptors on systemic blood vessels, sympathomimetics can cause
widespread vasoconstriction. Generalized vasoconstriction is most likely with oral agents. However,
even the topical agents can cause significant systemic vasoconstriction if used in excess.
● Pseudoephedrine is associated with abuse. By causing CNS stimulation, this sympathomimetic can
produce subjective effects similar to those of amphetamine. It is used to make meth.
-Guaifenesin
● An expectorant is a drug that renders cough more productive by stimulating the flow of respiratory
tract secretions.
● However, in almost all cases, efficacy is questionable. One agent—guaifenesin (Mucinex, Humibid,
and others]—may be an exception.
● for this drug to be effective, doses higher than those normally employed may be needed.
● Does not interact with many drugs (safe in most cases of polypharmacy)
-Side effects of latanoprost
● Systemic reactions are rare. The most significant side effect is a harmless heightened brown
pigmentation of the iris, which is most noticeable in patients whose irides are green-brown, yellow-
brown, or blue/gray-brown. Will stop progressing when discontinued.
