Guaifenesin [Mucinex]
26
Why are decongestant drops preferred for young children?
Because children are susceptible to toxicity and the number of drops can be precisely controlled, and drops allow better control of dosage than do sprays
27
Why are non-selective beta blocker glaucoma drops contraindicated in patients with COPD?
Blockade of beta2 receptors in the lungs can cause bronchospasms
28
What is the only ophthalmic beta blocker that can be used in patients with asthma and COPD and why?
betaxolol because it is beta1 selective

31
Most significant side effect seen with Latanoprost drops?
harmless heightened brown pigmentation of the iris
32
How do sunscreens protect against sunburn, photoaging of the skin, and photosensitivity reactions to certain drugs?
They impede penetration of UV radiation to viable cells of the skin
33
What type of sunscreen absorbs UV radiation and then dissipates it as heat?
Organic screens (chemical screens)
34
Minoxidil is a direct-acting vasodilator used primarily for severe hypertension but has topically can be used for what?
