Testim 1% (Testosterone)
Testim 1% (Testosterone) Uses, Dosage, Side Effects, Food Interaction and all others data.
Testim 1% (Testosterone) is a steroid sex hormone indicated to treat primary hypogonadism and hypogonadotropic hypogonadism. Testim 1% (Testosterone) antagonizes the androgen receptor to induce gene expression that causes the growth and development of masculine sex organs and secondary sexual characteristics.
Testim 1% (Testosterone) was isolated from samples and also synthesized in 1935.
Testim 1% (Testosterone) antagonizes the androgen receptor to induce gene expression that causes the growth and development of masculine sex organs and secondary sexual characteristics. The duration of action of testosterone is variable from patient to patient with a half life of 10-100 minutes. The therapeutic index is wide considering the normal testosterone levels in an adult man range from 300-1000ng/dL. Counsel patients regarding the risk of secondary exposure of testosterone topical products to children.

Uses
Testim 1% (Testosterone) is a hormone used to treat hypogonadism, breast carcinoma in women, or the vasomotor symptoms of menopause.
Testim 1% (Testosterone) is indicated to treat primary hypogonadism and hypogonadotropic hypogonadism.
Testim 1% (Testosterone) is also used to associated treatment for these conditions: Hypergonadotropic Hypogonadism, Hypogonadotrophic Hypogonadism, Idiopathic Hypogonadotropic Hypogonadism, Puberty, Delayed, Inoperable, metastatic Breast cancer
How Testim 1% (Testosterone) works
The androgen receptor exists in the cytoplasm bound to the heat shock proteins HSP90, HSP70, and other chaperones. After binding to an androgen, the androgen receptor dissociates from HSP90 and undergoes a conformational change to slow the rate of dissociation from the androgen receptor. The androgen-receptor complex is transported into the nucleus where it binds to DNA and recruits other transcriptional regulators to form a pre-initiation complex and eventually induce expression of specific genes.
Testim 1% (Testosterone) and its active metabolite dihydrotestosterone (DHT) antagonize the androgen receptor to develop masculine sex organs including the prostate, seminal vesicles, penis, and scrotum.
Antagonism of the androgen receptor is also responsible for the development of secondary sexual characteristics including facial and body hair, enlargement of the larynx, thickening of the vocal cords, and changes in muscle and fat distribution.
Toxicity
Data regarding an overdose with a topical testosterone product is not readily available. In the case of overdose with an injectable product, patients may present with a cerebrovascular event. Treat overdoses by stopping testosterone products, washing off any topical products with soap and water, and initiating symptomatic and supportive treatments.
Food Interaction
No interactions found.Testim 1% (Testosterone) Cholesterol interaction
[Major] Androgenic anabolic steroids may adversely affect serum lipids, including lowering HDL and elevating LDL levels.
These changes can be marked, particularly with the 17-alpha-alkyl derivatives (i.e., fluoxymesterone, methyltestosterone, oxandrolone, oxymetholone, and stanozolol), and may significantly impact the risk of atherosclerosis and coronary artery disease.
Patients with preexisting hyperlipoproteinemia may require closer monitoring during therapy with androgenic agents, and adjustments made accordingly in their lipid-lowering regimen.
Androgen therapy should be administered cautiously in patients with coronary artery disease or a history of ischemic heart disease.

Elimination Route
A single 100mg topical dose of testosterone has an AUC of 10425±5521ng*h/dL and a Cmax of 573±284ng/dL. Testim 1% (Testosterone) is approximately 10% bioavailable topically.
Half Life
The half life of testosterone is highly variable, ranging from 10-100 minutes.
Clearance
The mean metabolic clearance in middle aged men is 812±64L/day.
Elimination Route
90% of an intramuscular dose is eliminated in urine, mainly as glucuronide and sulfate conjugates. 6% is eliminated in feces, mostly as unconjugated metabolites.

FAQ
What is Testim 1% (Testosterone) used for?
Testim 1% (Testosterone) is used primarily to treat symptoms of sexual dysfunction in men and women and hot flashes in women. Potential benefits include improved libido, increased bone mass, and increased sense of well-being.

However, research has also linked Testim 1% (Testosterone) therapy with several side effects and possible complications. Possible negative effects of Testim 1% (Testosterone) therapy may include: an increased risk of cardiovascular complications.
How does Testim 1% (Testosterone) work?
Testim 1% (Testosterone) is a sex hormone that plays important roles in the body. In men, it's thought to regulate sex drive (libido), bone mass, fat distribution, muscle mass and strength, and the production of red blood cells and sperm. A small amount of circulating Testim 1% (Testosterone) is converted to estradiol, a form of estrogen.
What are the common side effects of Testim 1% (Testosterone)?
Common side effects may include:
- breast swelling;
- acne, increased facial or body hair growth, male-pattern baldness;
- increased or decreased interest in sex;
- headache, anxiety, depressed mood;
- increased blood pressure;
- numbness or tingly feeling;
- abnormal liver function tests;
- high red blood cell counts (hematocrit or hemoglobin);
- increased PSA (prostate-specific antigen); or
- pain, bruising, bleeding, redness, or a hard lump where the medicine was injected.
Is Testim 1% (Testosterone) safe during pregnancy?
If you are pregnant, avoid starting Testim 1% (Testosterone), as it will harm the developing fetus.
Is Testim 1% (Testosterone) safe during breastfeeding?
Testim 1% (Testosterone) delivered by sublingual drops, vaginal cream, and pellet implant was absorbed but not measurably excreted into breast milk. Testim 1% (Testosterone), delivered by a 100-mg subcutaneous pellet implant, was effective in relieving symptoms of Testim 1% (Testosterone) deficiency and therapy is safe for the breast-fed infant.
Can I drink alcohol with Testim 1% (Testosterone)?
Many doctors recommend limiting or quitting alcohol while taking Testim 1% (Testosterone). More than 90 percent of men with advanced liver disease also have low Testim 1% (Testosterone).
