Common use

Isoptin is a Ca2+-channel blocker which relaxes (widens) veins and arteries, which makes it easier for the heart to pump and this way Isoptin reduces its workload. Calcium triggers contraction of smooth muscles and when its entrance to the myocytes, it results in relaxation of the arterial muscles, improved oxygen delivery to the myocardial tissue, and decreased total peripheral resistance, systemic blood pressure, and after-load. Isoptin also decreases the conduction of electrical impulses through the heart that control the coordination of contraction, this slows the rate of contraction. Isoptin is used to treat hypertension, to treat angina, control some types of irregular heartbeats.



Dosage and direction

Take orally with or without food. Daily dose is 180-480 mg which may be taken as a single dose or divided in two or three intakes. Take exactly as prescribed by your doctor, never exceed the dose recommended to you.



Precautions

Avoid drinking alcoholic beverages, grapefruit juice or eating grapefruit. Alcohol is able worsen side effects of Isoptin (drowsiness and dizziness) while grapefruit interacts with components of the drug. Do not get up too fast from a sitting or lying position as you may feel dizzy.



Contraindications

Isoptin is contraindicated in patients with hypersensitivity to components of the medication, severe left ventricular dysfunction, hypotension (systolic pressure less than 90 mm Hg) or cardiogenic shock, sick sinus syndrome (except in patients with a functioning artificial ventricular pacemaker), atrioventricular block degree II-III (except in patients with a functioning artificial ventricular pacemaker), atrial flutter or atrial fibrillation and an accessory bypass tract (Wolff-Parkinson-White, Lown-Ganong-Levine syndromes).



Side effects

Arpamyl is usually well tolerated. Most common side effects include dizziness, weakness or fainting, swelling of the lower extremities, rash, headache, and constipation. Jaundice, swelling, difficulty breathing, rashes are also possible. If you experience severe side effects listed above seek for immediate medical attention.



Drug interaction

Isoptin inhibits elimination of alcohol, increases the efficacy of doxorubicin both in tissue culture systems and in patients. Cyclophosphamide, oncovin, procarbazine, prednisone (COPP) and the vindesine, adriamycin, cisplatin (VAC) cytotoxic drug regimens are able to decrease absorption of Isoptin. Co-administration of Isoptin with aspiring in rare cases increases risk of bleeding. Correction of digoxin dosage is important in patients treated with Isoptin. Chronic verapamil treatment can increase serum digoxin levels by 50% to 75% during the first week of therapy leading to digitalis toxicity. Co-administration with oral antihypertensive agents results in additive effects. Inform your doctor about all medications you take, especially about Disopyramide, Flecainide, Quinidine, Phenobarbital, Cyclosporin, medications which contain lithium. This medication may change results of certain liver tests to mildly abnormal.



Missed dose

Take the dose you forgot as soon as you remember. If it is almost time for your next intake just skip the next dose and return to your regular schedule.



Overdose

If you experience slow heartbeat and fainting, they may be symptoms of overdose. Seek for immediate medical attention if you suppose that too much of Isoptin was taken.



Storage

Store at room temperature 15-30 C (59-86 F) away from light, moisture, pets and children.

Antibiotics

Antibiotics is one of most prescribed group of medications. Antibiotics are antibacterial (antimicrobial agents) that kills bacteria(bactericidal) or stop the growth of the bacteria(bacteriostatic action).

Antibiotics are used to treat bacterial infections and are not indicated for the viral infections. Currently there is a big variety of antibiotics available. All the antibiotics are divided into two main groups according to the action mechanism:

  • Antibiotics with bactericidal action(penicillins, cephalosporins, aminoglycoside)
  • Antibacterial with bacteriostatic action(macrolides, tetracyclines)

Penicillins and cephalospororins are the most prescribed group of antibiotics. They belong to half-synthetic beta lactam antibiotics. These antibiotics work by inhibiting the enzymes responsible for the production of peptidoglycan. Peptidoglycan is a biopolimer that is a main structural component of the bacterial cell wall. The blockage of peptidoglycan synthesis leads to the lysis of the microorganisms.

Another group of preparations are aminoglycosides. However, these antibiotics are prescribed in rare cases. The most of aminoglycosides possesses nephrotoxicity, ototoxicity and cab cause neuromuscular blockage. Bactericidal action of aminoglycosides is related to the interfering with the synthesis of proteins on the ribisomes in the microbial cells. When aminoglycosides are used with penicillins and cephalosporins the sinergism against gram-positive and gram-negative microorganisms is observed.

Among all bacteriostatic antibiotics macrolides and tetracyclines are the most indicated groups. Therapeutic effect of macrolides is associated with inhibiting the synthesis of proteins on the ribosomes in the microbial cell. As usual macrolides exert bacteriostatic action, however in high amounts are able to exert bactericidal action on some microorganisms. Besides antibacterial action, some macrolides possesses immunomodulatory and anti-inflammatory action.

Another group of bacteriostatic antibiotics are used less frequently as many microorganisms became resistant to the this type of antibiotics. Bacteriostatic effect of the tetracyclines is associated with inhibiting the synthesis of proteins. Tetracycline are indicated in clamydia infections, rickettsial disease, some zoonosis, severe acne.

Antibiotics are indicated and used only in the cases of the bacteria is sensitive to the antibiotics. There some specific tests like antibiogram that will help to determine the right antibiotic and corresponding dose.
