Thrombin inhibitors are anticoagulants that bind to and inhibit the activity of thrombin therefore prevent blood clot formation. Thrombin inhibitors inactivate free thrombin and also the thrombin that is bound to fibrin. Thrombin has many important functions in the clotting pathway, so it is a good target for anticoagulants drugs.

Thrombin inhibitors are used to prevent arterial and venous thrombosis. They can be used to prevent and treat deep vein thrombosis, or used as prophylaxis in atrial fibrillation to avoid thromboembolism.

Topical steroids with anti-infectives are used to treat topical infections (generally skin infections) that have an inflammatory component.

Steroids are extremely effective anti-inflammatory agents. They suppress various parts of the inflammatory reaction. Different topical steroids have different potency ranging from mild to very potent topical steroids.

Topical anti-infective agents act locally by either killing or inhibiting the spread of the infectious agent. They include antibiotics, antibacterial, antifungal and antiviral agents.

These topical steroids and anti-infective agents are available as creams, ointments and gels that can be applied locally on the area that needs to be treated.

Use of these agents depends on the particular infection that needs to be treated. Topical steroids with antibiotics and antibacterial agents are used to treat bacterial infections that have inflammation, itching, redness, etc. The topical agent with antifungal and steroid is used to treat a fungal infection with inflammation, and the agent with an antiviral and steroid is used to treat viral infection with inflammation.

Thioxanthenes are typical (conventional) antipsychotic drugs structurally related to phenothiazines. They work as dopamine-2 (D2) receptor antagonists and suppress the effect of dopamine in the brain.

Thioxanthenes are high potency drugs: they have a high affinity for dopamine receptors compared to affinity for adrenergic and muscarinic receptors. Thioxanthene antipsychotics are used to treat schizophrenia.

Topical astringents are agents that cause skin cells or mucus membranes to contract or shrink, by precipitating proteins from their surface. When applied topically they dry, harden and protect the skin. They reduce bleeding from minor abrasions and are used to relieve skin irritations resulting from minor cuts, allergies, eczema, stretch marks, insect bites and so on. Topical astringents can be used in throat lozenges, mouthwash, creams, lotions, etc.

Tricyclic antidepressants (TCAs) act by inhibiting reuptake of norepinephrine and serotonin by blocking the transporters responsible for reuptake of these neurotransmitters. This inhibition elevates the concentration of neurotransmitters in the synapses and triggers further neurotransmission.

Tricyclic antidepressants are used to treat depression, bipolar disorder, anxiety, obsessive-compulsive disorder and other mood disorders. They are also effective as analgesics so are used to treat chronic pain and used for migraine prophylaxis.

Tyrosine kinase inhibitors are drugs that inhibit enzymes called tyrosine kinase that are critical in the proliferation pathway of cells. Tyrosine kinases are found in certain receptors or inside the cells. Inhibition of tyrosine kinase stops cell growth and multiplication, making them targets in the treatment of cancers.

Tyrosine kinase inhibitors are used to treat cancers that rely on growth factors or particular receptors that have tyrosine kinase domains for activation.
