All topical gels are formulated using a trans-organo gel base. This base
utilizes lecithin and a penetrating oil to provide better absorption. Although
these gels may be applied to various sites, they are most often applied to the
inside of the forearm (usually at bedtime). There is a trade-off in using in the trans-organo gel base instead of a
cosmetic type cream like Dermabase. The cosmetic creams are nice to apply, but
all contain mineral oil that can reduce absorption. The gel tends to be sticky
if doses are greater than ¼ tsp.; most women have no problem with this dosage
size. All gels are compounded so that ¼ tsp = 1 Gram Formulations: Oral testosterone USP is rapidly metabolized in the body and has limited
applications in HRT. However, sublingual and buccal forms will bypass enzymatic
and first pass liver transformation. Methyltestosterone is the most widely used oral testosterone (in Estratest).
Many primary care providers feel that even the half-strength Estratest is too strong for
many women. Some researchers have suggested that there is a therapeutic window
for optimal benefits--too little a dose being ineffective and too large a dose
causing side effects (particularly androgenic effects, agitation, and
depression). The suggested dose of methyltestosterone is 0.5mg/day. The disadvantage of methyltestosterone is that it shows no effect on
testosterone blood levels and therefore is difficult to monitor with blood
tests. However, because it is not converted to estrogen in the body, it may be
appropriate for those women concerned with high estrogen levels. Testosterone USP is better absorbed and more readily utilized by the body in
the form of a topical gel containing micronized testosterone that is applied
externally to the inside of the forearm or upper arm. Although this product does
not produce a local benefit to genital tissue, it will produce effective blood
levels and avoid first-pass liver transformation. Testosterone gel is the most widely used form of testosterone. It is
initially used daily; after several months applications of 3-4 times a week may
prove satisfactory. Primary care providers report that the usual dosage range for most women
is between 2.5 mg-5.0 mg daily. The 0.25% gel provides 2.5 mg testosterone in an
easily measured ¼ tsp dose. We do not recommend dispensing more than a 90-day
supply at a time to due to its short shelf life High strength testosterone gel has been effective in elevating testosterone
level in men. It is an excellent formulation for those men who cannot tolerate
the transdermal patches. The usual dose is Testosterone Gel 5 % -- ¼
teaspoonful applied to the forearm daily (usually at bedtime). Testosterone vaginal ointment has been used for years to treat lichen sclerosus. Initially, testosterone ointment 2% is used daily for a sufficient
period of time to restore tissue health --then used intermittently. DHEA taken orally is rapidly converted by the liver to testosterone. This
process can be slowed down by utilizing a formulation of oral capsules in which
the DHEA is suspended in oil. Like progesterone in oil, this formulation allows
direct absorption into the lymphatic system. Probably the best use of DHEA is in a transdermal gel that not only will
bypass the liver but will also allow it to be converted into estrogen and
testosterone in peripheral tissues. Since high doses of DHEA can be androgenic, low doses in the 10-25 mg range
have been suggested. |
