What is Tlando?

Tlando is a prescribed medicine that is a testosterone-based medicine. It is prescribed for adult males with low or no testosterone due to specific medical ailments.

It isn’t known whether this medicine can be used safely or effectively for youngsters younger than 18. Incorrect use of Tlando can impact bone growth in children.

Tlando can be classified as a controlled substance (CIII) because it is a source of testosterone, which can be a target for those who misuse prescription drugs. Keep your Tlando in a safe place to protect it. Do not give it to someone other people even if they suffer from similar symptoms to yours. The act of selling or giving away the medicine could harm other people and is illegal.

Tlando is not designed to be used by women.


TLANDO is an oral capsule containing testosterone undecanoate (TU) and has been developed for the treatment of hypogonadism in adult males.  TLANDO is proposed as testosterone replacement therapy (TRT) for the treatment of conditions associated with a deficiency or absence of endogenous testosterone (T) due to primary or hypogonadotropic hypogonadism, as per standard class TRT labeling.

There are various testosterone preparations with different routes of administration available in the United States (US). Each TRT therapy is approved to provide testosterone replacement therapy, but the various TRT agents have unique pharmacokinetic (PK) properties, limitations, risks, and safety concerns.  The only oral preparation approved for use in the US is 17-alpha-alkylated drugs that undergo first-pass metabolism and thus pose the risk of hepatotoxicity.


There are several challenges to developing a non-17-alpha alkylated oral testosterone formulation with an adequate PK profile, including providing adequate bioavailability, minimizing food effects, and having low variability in serum concentrations. TLANDO is an oral capsule product containing 112.5 mg of TU and a proprietary formulation composed primarily of non-triglyceride based lipids.  TLANDO is designed to enable absorption of TU predominantly via the intestinal lymphatic pathway. Testosterone undecanoate is a prodrug delivered as a straight chain fatty acid ester of testosterone, which is not alkylated at the 17alpha position. After being absorbed via the lymphatics, TU is converted to active testosterone by non-specific esterases. 

Currently, TU is available as an injectable product in the US (brand name, Aveed). Oral TU (Andriol) is not approved in the US but has been marketed for more than 20 years outside of the US in more than 80 countries, including Canada, for the treatment of male hypogonadism
