What is Haldol? Haldol is an antipsychotic medicine. It works by changing the actions of chemicals in your brain. Haldol is used to treat schizophrenia. It is also used to control motor and speech tics in people with Tourette's syndrome. Haldol may also be used for purposes not listed in this medication guide.

Important Information Haldol is not approved for use in psychotic conditions related to dementia. This medicine may increase the risk of death in older adults with dementia-related conditions. You should not use Haldol if you have Parkinson's disease or certain conditions that affect your central nervous system.

Before taking this medicine You should not use Haldol if you are allergic to it, or if you have: • Parkinson's disease; or • certain conditions that affect your central nervous system (such as severe drowsiness, or slowed thinking caused by taking other medicines or drinking alcohol). Haldol is not approved for use in psychotic conditions related to dementia. This medicine may increase the risk of death in older adults with dementia-related conditions. To make sure Haldol is safe for you, tell your doctor if you have:

• liver disease; • kidney disease; • heart disease, angina (chest pain); • a thyroid disorder; • epilepsy or other seizure disorder; • personal or family history of long QT syndrome; • an electrolyte imbalance (such as low levels of potassium or magnesium in your blood); or • if you take a blood thinner (warfarin, Coumadin, Jantoven). It is not known whether this medicine will harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant. Taking antipsychotic medication during the last 3 months of pregnancy may cause problems in the newborn, such as withdrawal symptoms, breathing problems, feeding problems, fussiness, tremors, and limp or stiff muscles. However, you may have withdrawal symptoms or other problems if you stop taking your medicine during pregnancy. If you become pregnant while taking Haldol, do not stop taking it without your doctor's advice. Haloperidol can pass into breast milk and may harm a nursing baby. You should not breast-feed while using this medicine.

How should I take Haldol? Follow all directions on your prescription label. Your doctor may occasionally change your dose to make sure you get the best results. Do not take Haldol in larger or smaller amounts or for longer than recommended. medicine at the same time each day.

Your blood pressure will need to be checked often. Your chest pain may become worse when you first start taking amlodipine or when your dose is increased. Call your doctor if your chest pain is severe or ongoing. If you are being treated for high blood pressure, keep using amlodipine even if you feel well. High blood pressure often has no symptoms. You may need to use blood pressure medicine for the rest of your life. Your hypertension or heart condition may be treated with a combination of drugs. Use all medications as directed by your doctor. Read the medication guide or patient instructions provided with each medication. Do not change your doses or stop taking any of your medications without your doctor's advice. This is especially important if you also take nitroglycerin. Amlodipine is only part of a complete program of treatment that may also include diet, exercise, weight control, and other medications. Follow your diet, medication, and exercise routines very closely. Store at room temperature away from moisture, heat, and light.

What happens if I miss a dose? Take the missed dose as soon as you remember. If you are more than 12 hours late, skip the missed dose. Do not take extra medicine to make up the missed dose

What is amlodipine?

Amlodipine is a calcium channel blocker that dilates (widens) blood vessels and improves blood flow. Amlodipine is used to treat chest pain (angina) and other conditions caused by coronary artery disease. Amlodipine is also used to treat high blood pressure (hypertension). Lowering blood pressure may lower your risk of a stroke or heart attack. Amlodipine is for use in adults and children who are at least 6 years old.

Important information Before taking amlodipine, tell your doctor if you have congestive heart failure or liver disease. Drinking alcohol can further lower your blood pressure and may increase certain side effects of amlodipine.

If you are being treated for high blood pressure, keep using amlodipine even if you feel well. High blood pressure often has no symptoms. You may need to use blood pressure medication for the rest of your life. Amlodipine is only part of a complete program of treatment that may also include diet, exercise, weight control, and other medications. Follow your diet, medication, and exercise routines very closely. Tell your doctor about all other heart or blood pressure medications you are taking. Your chest pain may become worse when you first start taking amlodipine or when your dose is increased. Call your doctor if your chest pain is severe or ongoing. The interpretation of any intuitionistically valid formula in the infinite Heyting algebra described above results in the top element, representing true, as the valuation of the formula, regardless of what values from the algebra are assigned to the variables of the formula.[7] Conversely, for every invalid formula, there is an assignment of values to the variables that yields a valuation that differs from the top element.[8][9] No finite Heyting algebra has both these properties.[7]

Kripke semantics[edit] Main article: Kripke semantics Building upon his work on semantics of modal logic, Saul Kripke created another semantics for intuitionistic logic, known as Kripke semantics or relational semantics.[10]

Tarski-like semantics[edit] It was discovered that Tarski-like semantics for intuitionistic logic were not possible to prove complete. However, Robert Constable has shown that a weaker notion of completeness still holds for intuitionistic logic under a Tarski-like model. In this notion of completeness we are concerned not with all of the statements that are true of every model, but with the statements that are true in the same way in every model. That is, a single proof that the model judges a formula to be true must be valid for every model. In this case, there is not only a proof of completeness, but one that is valid

according to intuitionistic logic.[11]

Relation to other logics[edit] Intuitionistic logic is related by duality to a paraconsistent logic known as Brazilian, anti-intuitionistic or dual-intuitionistic logic.[12] The subsystem of intuitionistic logic with the FALSE axiom removed is known as minimal logic. Relation to many-valued logic[edit] Kurt Gödel in 1932 showed that intuitionistic logic is not a finitelymany valued logic. (See the section titled Heyting algebra semantics above for a sort of "infinitely-many valued logic" interpretation of intuitionistic logic.) Relation to intermediate logics[edit] Any finite Heyting algebra which is not equivalent to a Boolean algebra defines (semantically) an intermediate logic. On the other hand, validity of formulae in pure intuitionistic logic is not tied to any individual Heyting algebra but relates to any and all Heyting algebras at the same time. Relation to modal logic[edit] Any formula of the intuitionistic propositional logic may be translated into the normal modal logic S4 as follows:

⊥

=⊥

∗

A

=◻A

if A is prime (a positive literal)

∗

(A∧B )

= A

∗

∗

∧ B ∗

(A∨B )

= A

∗

∗

∨ B ∗

(A→B

=◻

)

( A

∗

∗

→ B ∗

) (¬A )

=◻(¬( A

∗

∗

¬ A := A → ⊥

)) {\displaystyle {\begin{aligned}\bot ^{*}&=\bot \\A^{*}&=\Box A&&{\text{if }}A{\text{ is prime (a positive literal)}}\\(A\wedge B)^{*}&=A^{*}\wedge B^{*}\\(A\vee B)^{*}&=A^{*}\vee B^{*}\\(A\to B)^{*}&=\Box \left(A^{*}\to B^{*}\right)\\(\neg A)^{*}&=\Box (\neg (A^{*}))&&\neg A:=A\to \bot \end{aligned}}}

and it has been demonstrated[13] that the translated formula is valid in the propositional modal logic S4 if and only if the original formula is valid in IPC. The above set of formulae are called the Gödel– McKinsey–Tarski translation. There is also an intuitionistic version of modal logic S4 called Constructive Modal Logic CS4.[14]
