Ibuprofen

used to relieve the symptoms of arthritis, primary dysmenorrhoea, fever; and as an analgesic, especially where there is an inflammatory component.

Indications

rheumatoid arthritis, osteoarthritis, juvenile rheumatoid arthritis, primary dysmenorrhoea

fever, relief of acute and/or chronic pain states in which there is an inflammatory component

MOA

inhibition of  cyclooxygenase (COX); thus inhibiting prostaglandin synthesis.

 Other sedatives: carisoprodol, cyclobenzaprine, and methocarbamol are used for muscle relaxation.

Baclofen
1. Used in spasticity states to relax skeletal muscle.
2. Occasionally used in trigeminal neuralgia.

Antihistamines (first-generation H1 receptor blockers)
1. Used for sedation (e.g., diphenhydramine).

Ethyl alcohol

Adverse effects 

Nitrates 
– Headache, hypotension, dizziness, lightheadedness, tachycardia, palpitations 

Beta-adrenergic blocking agents
– hypotension, bradycardia, bronchospasm, congestive heart failure 

Calcium channel blockers 
– hypotension, dizziness, lightheadedness, weakness, peripheral edema, headache, congestive heart failure, pulmonary edema, nausea, and constipation 

Drugs that increase effects of Antianginal drugs 
• Antihypertensive 
• Diuretics 
• Phenothiazine antipsychotic agents
• Cimetidine 
• Digoxin 

Drugs that decrease effects of Antianginal
• Adrenergic drugs - epinephrine 
• Anticholinergic 
• Calcium salts 
• Phenobarbital, Phenytoin

Adjunctive Antianginal Drugs

In addition to antianginal drugs, several other drugs may be used to control risk factors and prevent progression of myocardial ischemia to myocardial infarction and sudden cardiac death.

These may include:
• Aspirin. This drug has become the standard of care because of its antiplatelet (ie, antithrombotic) effects. Recommended doses vary from 81 mg daily to 325 mg daily or every other day; apparently all doses are beneficial in reducing the possibility of myocardial reinfarction, stroke, and death. Clopidogrel 75 mg/day,
Is an acceptable alternative for individuals with aspirin allergy.

• Antilipemics. These drugs may be needed by clients who are unable to lower serum cholesterol levels sufficiently with a low-fat diet. Lovastatin or a related “statin” is often used. The goal is usually to reduce the serum cholesterol level below 200 mg/dL and lowdensitylipoprotein cholesterol to below 
130 mg/dL.

• Antihypertensives. These drugs may be needed for clients with hypertension. Because beta blockers and calcium channel blockers are used to manage hypertension as well as angina, one of these drugs may be effective for both disorders.

Sympatholytics And Alpha Adrenergic Blockers 

Types 
1.    Alpha 1-receptor blockers: prazocin,doxazocin. 
2.    Centrally acting alpha 2- agonists: methyldopa, clonidine. 
3.    Peripherally acting adrenergic antagonists: reserpine. 
4.    Imidazoline receptor agonists: rilmenidine, moxonidine. 
 
Advantages 

- Alpha1- receptor blockers and imidazoline receptor agonists improve lipid profile and insulin sensitivity. 
- Methyldopa: increases renal blood flow. Drug of choice during pregnancy. 
- Reserpine: neutral metabolic effects and cheap. 

Indications: 

- Diabetes mellitus: alpha1- receptor blockers, imidazoline receptor agonists. 
- Dyslipidemia: alpha 1- receptor blockers, imidazoline receptor agonists. 
- Prostatic hypertrophy: alpha 1- receptor blockers. 
- When there is a need for rapid reduction in blood pressure: clonidine. 

Side Effects 

- Prazocin: postural hypotension, diarrhea, occasional tachycardia, and tolerance (due to fluid retention). 
- Methyldopa: sedation, hepatotoxicity, hemolytic anemia, and tolerance. 
- Reserpine: depression, lethargy, weight loss, peptic ulcer, diarrhea, and impotence
- Clonidine: dry mouth, sedation, bradycardia, impotence, and rebound hypertension if stopped suddenly. 

Considerations 
- Prazocin, methyldopa, and reserpine should be combined with a diuretic because of fluid retention. 

Direct Arterial Vasodilators 

Types: hydralazine, diazoxide, nitroprusside, and minoxidil

ISOPRENALINE

It is beta-receptor stimulant, which stimulates the heart and causes tachycardia.
It relaxes the smooth muscles particularly the bronchial and GIT. It is mainly used in bronchial asthma, in the treatment of shock and as a cardiac stimulant in heart block. 

ORCIPRENALINE
Is a potent β-adrenergic agonist.
Receptor sites in the bronchi and bronchioles are more sensitive to the drug than those in the heart and blood vessels.

AMPHETAMINE 

increases the systolic and diastolic blood pressure. Amphetamine is a potent CNS stimulant and causes alertness, insomnia, increased concentration, euphoria or dysphoria and increased work capacity.

Amphetamines are drugs of abuse and can produce behavioural abnormalities and can precipitate psychosis. 

PHENYLEPHRINE
It is used as a nasal decongestant and mydriatic agent and also in the treatment of paroxysmal supraventricular tachycardia.

UTERINE RELAXANTS (TOCOLYTICS)

ISOXSUPRINE
Isoxsuprine has a potent inhibitory effect on vascular and uterine smooth muscle and has been used in the treatment of dysmenorrhoea, threatened abortion, premature labour and peripheral vascular diseases. 
 

Griseofulvin

• Griseofulvin is an antifungal drug. It is used both in animals and in humans, to treat ringworm infections of the skin and nails. It is derived from the mold Penicillium griseofulvum.
• It is administered orally.
