Acids and bases in the Brnsted model therefore exist as conjugate pairs whose formulas are related by the gain or loss of a hydrogen ion. Our use of the symbols HA and A- for a conjugate acid-base pair does not mean that all acids are neutral molecules or that all bases are negative ions. It signifies only that the acid contains an H+ ion that isn't present in the conjugate base.
Zovirax Ointment. Zovirax is a brand name for a prescription ointment cream that contains the anti-viral medication acyclovir. This medicated ointment is commonly used to treat genital herpes and cold sores in the mouth.
Treatment. Shingles is often treated with oral antiviral drugs: acyclovir (Zovirax), famciclovir (Famvir) or valacyclovir (Valtrex). These medicines should be started within the first 3 days of the onset of the rash. In fact, the sooner the medication is started the better. These medications are generally safe and well tolerated.
