- Postherpetic Neuralgia. Medications.
Analgesics
Capsaicin (Zostrix-HP), an extract from hot chili peppers, is more efficacious for post-herpetic neuralgia than placebo. Capsaicin cream must be applied to the affected area three to five times daily.
Lidocaine patches reduce pain intensity, with minimal systemic absorption. The effect lasts only four to 12 hours with each application.
Acetaminophen (eg, Tylenol) and nonsteroidal anti-inflammatory drugs [...]

- Herpes Treatment. Anti-Herpes Medications.
Treatment of herpes zoster
Antiviral agents have been shown to decrease the duration of herpes zoster rash and the severity of pain associated with the rash. Benefits have been demonstrated in patients who received antiviral agents within 72 hours after the onset of rash.
Acyclovir Zovirax therapy appears to produce a moderate reduction in the development of [...]

- Herpes
Herpes zoster (shingles) results from reactivation of the varicella-zoster virus. Herpes zoster is a sporadic disease with an estimated lifetime incidence of 10 to 20 percent. The incidence of herpes zoster increases sharply with advancing age, roughly doubling in each decade past the age of 50 years. Herpes zoster is uncommon in persons less than [...]

- Antibiotics. Azlocillin. Oral oxacillin.
Azlocillin is like piperacillin in its spectrum and its uses. It basically is essentially as good as piperacillin and I would suggest that whichever one you use depends on which one your institution can get the least expensively. You do not need to have both azlocillin and piperacillin in a given hospital.
Penicillin H resistant penicillins [...]

- Antibiotics. Ticarcillin. Carbenicillin.
Ticarcillin is also a penicillin derivative but its major activity, rather than being Gram positive, is Pseudomonas. That is the principal use of ticarcillin. We give it IV in large doses. It is impractical to give this product IM. It contains about 5 milliequivalents of sodium per gram and we give big doses. So we [...]

- Antibiotics. Penicillin.
Penicillin resistant Pneumococcus and other bacterial resistance have become a rapidly increasing problems. So we have to be careful with the way we use antibiotics as we do any other drug. Some resistant mechanisms work by competitive antagonism. The sulfas are folic acid synthesis inhibitors. Those bacteria that are obligate folate synthesizers are inhibited because [...]

- Antidepressants
Alternative applications of “antidepressants”
Although the evidence of efficacy of antidepressants, as a class, is not as convincing as for other types of drugs, there is growing clinical and research evidence to support a widening range of potential indications of these drugs. The partial success of the SSRIs as a group in ameliorating
OCD is encouraging, as [...]

- Dosing of antidepressants. Treatment-resistance
Treatment-resistance
The problem of apparent “treatment-resistance” in depression requires further study, but many cases respond when a patient actually is willing to follow a previously recommended treatment, or high doses are accepted and pursued for at least 6-8 weeks. Some cases may represent destabilizing effects of overly aggressive antidepressant treatment of patients with overlooked bipolarity, but [...]

Antidepressants
Types of antidepressants
Antidepressants currently fall into five major categories: [1] tertiary amine tricyclics (amitriptyline, clomipramine, doxepin, imipramine, trimipramine), secondary amine tricyclics (amoxapine, desipramine, maprotiline, nortriptyline, protriptyline); [2] monoamine oxidase (MAO) inhibitors (phenelzine, tranylcypromine, selegiline [(-)-deprenyl], and experimental short-acting MAO-A inhibitors (eg,, moclobemide [Manerex], marketed in Canada); [3] serotonin-reuptake inhibitors: (SSRIs) clomipramine, citalopram, [±]-fluoxetine, fluvoxamine, sertraline, [...]

“The inability to attain and/or maintain penile erection sufficient for satisfactory sexual performance” (NIH Consensus Development Panel on Impotence)
