What are t4 and t3?
T4 is an active Thyroid hormone.
Thyroxine.
Affects metabolic, growth, reproductive and immune functions.
Also regulates lipid and carbohydrate metabolism.
Helps control body temperature.Stored in the Thyroid gland.Converted to T3 once released into the blood stream.T3 is an active Thyroid hormone.Tri-iodothyronine.Affects metabolic, growth, reproductive and immune functions.Also regulates lipid and carbohydrate metabolism.Helps control body temperature.
Stored in the Thyroid gland.Slide5
Handling i-131: why don’t vet clinics like to handle this?
Veterinary Concerns are as follows:
Safety
Training
Cost of the drug
Radiation exposure to the employees and family.Elimination of the drug is in the urine and feces. Exposure of the drug is high risk for 2 weeks.
I
-131
, known as radioactive iodine, is used for treatment of hyperthyroidism with a cure rate of 95%. All cats must have a CBC, chemistry profile, urinalysis and chest and abdominal radiographs performed within 30 days of the scheduled I-131 treatment. Prior to treatment, 2 weeks in advance, y/d and
M
ethimazole
should be stopped and, 1 week in advance, retesting of the thyroid hormone levels should be done. This is to be able to
accurately
dose the
I-131
.Slide6
Primary and secondary hyperthyroidism
Primary Hyperthyroidism
is a disease that affects a felines parathyroid glands to produce increased amounts of the hormone responsible that controls calcium, vitamin D and phosphorus levels in the bone and blood. Increased amounts of parathyroid hormone (PTH) can trigger calcium to be released from bones and tissue into the bloodstream. Elevated levels of calcium in the blood may lead to
hypocalcaemia.
The imbalanced calcium levels may interfere with the function of organs such as the heart and kidneys.
Secondary Hyperthyroidism
is a complication of chronic renal disease characterized by the increasing endogenous levels of parathyroid gland hormone (PTH). This disease is more common than Primary Hyperthyroidism. In contrast to primary hyperthyroidism, renal secondary hyperthyroidism tends not to be self-sufficient.Slide7
Safety and dispensing of Methimazole
Take caution on the medications similarity because they may not me similar at all. There is two different types of
thyroidism
. Her dog could be hypo while your mother may be hyper and that mix up of medications would be bad for either one’s health. You should never take another persons or pets prescription. The concentration and the drug name of the tablet could be different and there could be other drug interactions with other medications.
When it comes to handling medications that are in an envelope she should be careful the dog does not get into that package and take multiples. A safe and reliable container is a child proof container. Some bottles come with a different lid but even if the dog got hold of the bottle she might still be able to ingest multiples due to the bottle being easily operable. Slide8
How many mg of methimazole will the cat receive each treatment?
The cat has been prescribed to get 2.5 mg of Methimazole each treatment

When storing and
handling
Methmazole
What is an expired drug?
An expiration date is stamped on the side of the drug bottle
. This is the date at which the manufacturer can still guarantee the full potency and safety of the drug. After this time you are unable to sell the product to the public.What should be done with expired Methimazole?Steps to proper disposalSee if there is a medicine take back program in your area
Dispose of in your household trash.
Mix medicines (do NOT crush tablets or capsules) with an unpalatable substance such as kitty litter or used coffee
grounds
Place the mixture in a container such as a sealed plastic bag
Throw the container in your household trash
Before throwing out your empty pill bottle or other empty medicine packaging, remember to scratch out all information on the prescription label to make it unreadable
Do not discard this drug down the toilet due to it ending up in the water supply
Methimazole
should be maintained at room temperature. The acceptable limits for the room temperature are as follows:
Store at room temperature between 15 and 30 degrees C (59 and 86 degrees F
)..
Store away from light and moisture.Slide11
How does methimazole work and when can I stop giving it?
Pharmacology/Actions
Methimazole interferes with iodine incorporation, which inhibits the synthesis of they excess thyroid hormones in circulation.
How long do you give this drug?
For lifetime ?Slide12
After 2 months, how many ounces has the cat gained?
This looks blank
The cat started out with a weight of 5.28 pounds.
2.4 kg X 2.2 lb/kg= 5.28 lb
After 2 months, the cat weighs 5.8 pounds.5.28 lb X 16 oz/lb= 84.48 oz5.8 lbX 16 oz/lb= 92.8 oz92.8 oz-84.48 oz= 8.32 ozThe cat gained 8.32 ounces.Slide13
